FAR EASTERN UNIVERSITY INSTITUTE OF NURSING SECOND SEMESTER – AY 2020 – 2021 NUR 1210 – NCM 109 CARE OF THE MOTHER AND CHILD AT RISK OR WITH PROBLEM MOULE #1 – FRAMEWORK FOR MATERNAL AND CHILD HEALTH NURSING INTRODUCTION This module discusses the current situation of maternal and child health in the Philippines and the causes of the maternal and pediatric mortality, morbidity, and maternal risk assessment. It also includes the basic principles by which disorders can be inherited and information about the necessary assessments, care, and guidelines for counseling of families if it is discovered that there is a potential for a genetic disorder in the family. Such information can influence the health of a childbearing or childrearing family for generations to come. LEARNING OUTCOMES: After the successful completion of the module you should be able to: LO1 Integrate current situation of maternal and child health in the Philippines and concepts of genetic inheritance in the formulation and application of appropriate nursing care to mothers and children at-risk / high risk to achieve quality maternal and child health nursing care.

Maternal and Neonatal Mortality II. High Risk Maternal Condition III. Genetics and Genetic Counselling IV. Nursing process of Genetic Assessment and Counselling CONTENT The health of Filipino mothers and children determines the health of the next generation of Filipinos. This is the primary goal of maternal and child health nursing care stated simply as the promotion and maintenance of optimal family health to ensure cycles of optimal childbearing and childrearing. I. Maternal, Neonatal and Child Mortality Significant improvements in maternal and childcare have been realized in the past four decades. However, pregnancy and childbirth still pose a great risk to Filipino women of the reproductive age (DOH, 2011). Maternal mortality rate is still high, reported by UNICEF, 2009 at 160 per 100,000 live births declining slowly to 120 in 2013. Furthermore, UNICEF also reported the maternal situation in the Philippines. § 160 women for every 100,000 births die. § Roughly over 11 women die every day. § 7 out of 10 deaths occur at childbirth or within a day after delivery. § 4 out of 10 deaths are due to complications and widespread infections § For every death, 40 more women get sick. § 8 out of 10 births in rural areas are delivered outside a health facility 2 |P a g e NUR 1210 – MATERNAL CONCEPT (Melanie C.

This is followed by hypertension complicating pregnancy, childbirth and puerperium; postpartum hemorrhage and pregnancy with abortive outcome (DOH, 2011). These deaths of women while pregnant or within 42 days of termination of pregnancy, irrespective of the duration and site of the pregnancy, from any cause related to or aggravated by the pregnancy or its management but not from accidental or incidental causes.

Mother-to-child transmission of HIV continues to be a major problem, with up to 45 per cent of HIV-infected mothers transmitting infection to their children. In 2013, although the infant mortality rate slightly increased, the number of registered infant deaths slightly decreased by more than one percent, from last year’s 22,254 cases to 21,992 cases. It comprised of 4.1 percent of the total deaths (531,280) reported during the year. This represented a daily average of 60 infant deaths and was equivalent to an Infant Mortality Rate (IMR) of 12.5 deaths per thousand live births. The top three leading causes of infant mortality were Pneumonia (3,146; 14.3%); Bacterial sepsis of newborn (2,731; 12.4%); and Respiratory distress of newborn (2,347; 10.7%). The listed top ten leading causes of infant mortality in 2013 were the same with what was recorded in 2012 which only differ in ranks (Figure 1) 4 |P a g e NUR 1210 – MATERNAL CONCEPT (Melanie C.

Infant mortality These direct causes of maternal and neonatal deaths require care by skilled health professionals in well-equipped facilities. However, more than 59% of births take place at home, with more than 25% of the births attended by traditional birth attendants or hilots. This contributes to the three delays that lead to maternal and neonatal deaths. 1. Delay in identification of complications a. Failure to recognize danger signs b. Lack of money c. Unplanned/unwanted pregnancy d. Lack of companion in going to health facility e. No person to take care of children/home. f. Fear of being ill-treated in health facility 5 |P a g e NUR 1210 – MATERNAL CONCEPT (Melanie C.

Lack of community support 3. Delay in management of complications a. Lack of health care providers b. Shortage of supplies c. Lack of equipment d. Lack of competence of health providers e. Weak referral system The country is on target in its efforts towards lowering child mortality rate, with infant mortality rate at 25.72 per 1,000 births in 2008 and under-five mortality rate at 32.8 per 1,000 live births. The Food and Nutrition Research Institute (FNRI), however, estimates that prevalence of underweight among children less than five years of age. It is worth noting that man of the leading causes of infant mortality (Figure 1) can be prevented by quality and accessible maternal and newborn, and child services and improvement in maternal, infant and child nutrition.

Addressing the risk factors of maternal complication and identifying danger signs early reduce significantly both maternal and fetal mortality. The danger signs of pregnancy which must be referred immediately are: 1. High fever 2. Severe vomiting 3. Severe headache 4. Pallor and laboured breathing 5. Swelling of hands and feet 6.

Furthermore, fetal death and infant morbidity and mortality will be avoided. III. Genetics and Genetic Counselling Although the number three leading cause of infant mortality is chromosomal abnormalities, limited attention has been given to birth defects and other genetic conditions (http://www.doh.gov.ph/mortality). Table 2 describes the prevalence of congenital disorders by cause in the Philippines. This situation has been aggravated by the small number of geneticists and genetic counselors who can provide genetic diagnosis, management, and counseling services to patients. The delivery of medical genetic services thus remains a challenge in both private and public sectors. 10 |P a g e NUR 1210 – MATERNAL CONCEPT (Melanie C.

Inherited or genetic disorders are disorders that can be passed from one generation to the next. They result from some disorder in gene or chromosome structure and occur in 5% to 6% of newborns. o Genetics is the study of heredity and the variation of inherited characteristics o Cytogenetics is the study of chromosomes by light microscopy and the method by which chromosomal aberrations are identified. A. Nature of Inheritance o Genes are the basic units of heredity that determine both the physical and cognitive characteristics of people. It is composed of segments of DNA, they are woven into strands in the nucleus. o Chromosomes are threadlike structures of nucleic acids and protein found in the nucleus of most living cells, carrying genetic information in the form of genes 11 |P a g e NUR 1210 – MATERNAL CONCEPT (Melanie C. Tapnio, MAN, RN) Prepared by MCN FEU Faculty Lecturers January 2021  FAR EASTERN UNIVERSITY INSTITUTE OF NURSING SECOND SEMESTER – AY 2020 – 2021 NUR 1210 – NCM 109 CARE OF THE MOTHER AND CHILD AT RISK OR WITH PROBLEM o In humans, each cell, except for the sperm and ovum, contains 46 chromosomes (22 pair of autosomes and 1 pair of sex chromosomes). o Spermatozoa and ova each carry only half of the chromosome number, or 23 chromosomes. For each chromosome in the sperm cell, there is a like chromosome of similar size and shape and function (autosome, or homologous chromosome) in the ovum. Because genes are always located at fixed positions on chromosomes, two like genes (alleles) for every trait are represented in the ovum and sperm on autosomes. The one chromosome in which this does not occur is the chromosome for determining gender. o If the sex chromosomes are both type X (large symmetric) in the zygote formed from the union of a sperm and ovum, the individual is female. If one sex chromosome is an X and one a Y (a smaller type), the individual is a male. o A person’s phenotype refers to his or her outward appearance or the expression of genes. o A person’s genotype refers to his or her actual gene composition. It is impossible to predict a person’s genotype from the phenotype, or outward appearance. o A person’s genome is the complete set of genes present o A normal genome is abbreviated as 46XX or 46XY. B. Mendelian Inheritance: Dominant and Recessive Patterns o The principles of genetic inheritance of disease are the same as those that govern genetic inheritance of other physical characteristics, such as eye or hair color. These principles were discovered and described by Gregor Mendel, an Austrian naturalist, in the 1800s and are known as mendelian laws. o Homozygous traits are two like chromosomes (one from the mother and one from the father) o Heterozygous traits occur when the genes differ (a healthy gene from o the mother and an unhealthy gene from the father, or vice versa) o Dominant genes are always expressed in preference to the recessive genes. For example, a gene for brown eyes is dominant over one for blue eyes which is 12 |P a g e NUR 1210 – MATERNAL CONCEPT (Melanie C. Tapnio, MAN, RN) Prepared by MCN FEU Faculty Lecturers January 2021  FAR EASTERN UNIVERSITY INSTITUTE OF NURSING SECOND SEMESTER – AY 2020 – 2021 NUR 1210 – NCM 109 CARE OF THE MOTHER AND CHILD AT RISK OR WITH PROBLEM recessive; a child is born with a gene for brown eyes and a recessive one for blue eyes will have brown eyes. o An individual with two homozygous genes for a dominant trait is said to be homozygous dominant; an individual with two genes for a recessive trait is homozygous recessive. 1. Autosomal Dominant Disease o Although more than 3000 autosomal dominant disorders are known, only a few are commonly seen because the majority of these are not compatible with life after birth. With an autosomal dominant condition, either a person has two unhealthy genes (is homozygous dominant) or is heterozygous, with the gene causing the disease stronger than the corresponding healthy recessive gene for the same trait. o If a person who is heterozygous for an autosomal dominant trait (the usual pattern) mates with a person who is free of the trait, as shown in Figure 1, the chances are even (50%) that a child born to the couple would have the disorder or would be disease and carrier free (i.e., carrying no affected gene for the disorder). o Two heterozygous people with a dominantly inherited disorder are unlikely to choose each other as reproductive partners. If they do there would be only a 25% chance of a child’s being disease and carrier free, a 50% chance that the child would have the disorder as both parents do, and a 25% chance that a child would be homozygous dominant (i.e., have two dominant disorder genes), a condition that probably would be incompatible with life (Figure 2) 13 |P a g e NUR 1210 – MATERNAL CONCEPT (Melanie C.

Autosomal Dominant Inheritance In assessing family genograms (maps of family relationships) for the incidence of inherited disorders, a number of common findings are usually discovered when a dominantly inherited pattern is present in a family (Fig. 3) : g. One of the parents of a child with the disorder also will have the disorder (a vertical transmission picture). h. The sex of the affected individual is unimportant in terms of inheritance. i. There is usually a history of the disorder in other family members. An example of autosomal dominant disease is Huntington disease. It is a progressive neurologic disorder characterized by loss of motor control and intellectual deterioration, symptoms usually manifest at 35-45 y/o. 14 |P a g e NUR 1210 – MATERNAL CONCEPT (Melanie C.

Family genogram of Autosomal Dominant Inheritance 2. Autosomal Recessive Inheritance o More than 1500 autosomal recessive disorders have been identified. Such diseases do not occur unless two genes for the disease are present (i.e., a homozygous recessive pattern). Examples include cystic fibrosis, albinism, Tay-Sachs disease, galactosemia, phenylketonuria, Rh Incompatibility) An example of autosomal recessive inheritance is shown in Figure 4. Both parents are disease free of cystic fibrosis, but both are heterozygous in genotype, so they carry a recessive gene for cystic fibrosis. When this genetic pattern occurs, a. there is a 25% chance that a child born to a couple will be disease and carrier free (homozygous dominant for the healthy gene); b. a 50% chance that the child will be, like the parents, free of disease but carrying the unexpressed disease gene (heterozygous); c. a 25% chance that the child will have the disease (homozygous recessive). 15 |P a g e NUR 1210 – MATERNAL CONCEPT (Melanie C. Tapnio, MAN, RN) Prepared by MCN FEU Faculty Lecturers January 2021  FAR EASTERN UNIVERSITY INSTITUTE OF NURSING SECOND SEMESTER – AY 2020 – 2021 NUR 1210 – NCM 109 CARE OF THE MOTHER AND CHILD AT RISK OR WITH PROBLEM Figure 4. Autosomal Recessive Inheritance o When family genograms are assessed for the incidence of inherited disease, situations commonly discovered when a recessively inherited disease is present in the family include (Fig.5): a. Both parents of a child with the disorder are clinically free of the disorder. b. The sex of the affected individual is unimportant in terms of inheritance. c. The family history for the disorder is negative—that is, no one can identify anyone else who had it (a horizontal transmission pattern). A known common ancestor between the parents sometimes exists. This explains how both male and female came to possess a like gene for the disorder. 16 |P a g e NUR 1210 – MATERNAL CONCEPT (Melanie C. Tapnio, MAN, RN) Prepared by MCN FEU Faculty Lecturers January 2021  FAR EASTERN UNIVERSITY INSTITUTE OF NURSING SECOND SEMESTER – AY 2020 – 2021 NUR 1210 – NCM 109 CARE OF THE MOTHER AND CHILD AT RISK OR WITH PROBLEM Figure 5. Family genogram: Autosomal Recessive Inheritance 3. X-Linked Dominant Inheritance Some genes for disorders are located on, and therefore transmitted only by, the female sex chromosome (the X chromosome). There are about 300 known disorders associated this way and their transmission is termed X-linked inheritance. If the affected gene is dominant, only one X chromosome with the trait need be present for symptoms of the disorder to be manifested (Fig. 6). Figure 6. X-linked Dominant Inheritance Family characteristics seen with this type of inheritance usually include: a. All individuals with the gene are affected (the gene is dominant). 17 |P a g e NUR 1210 – MATERNAL CONCEPT (Melanie C. Tapnio, MAN, RN) Prepared by MCN FEU Faculty Lecturers January 2021  FAR EASTERN UNIVERSITY INSTITUTE OF NURSING SECOND SEMESTER – AY 2020 – 2021 NUR 1210 – NCM 109 CARE OF THE MOTHER AND CHILD AT RISK OR WITH PROBLEM b. All female children of affected men are affected; all male children of affected men are unaffected. c. It appears in every generation. d. All children of homozygous affected women are affected. Fifty percent of the children of heterozygous affected women are affected (Fig. 7). An example of a disease in this group is Alport’s syndrome, a progressive kidney failure disorder. Figure 7. Family genogram: X-linked Dominant inheritance 4. X-Linked Recessive Inheritance The majority of X-linked inherited disorders are not dominant, but recessive. When the inheritance of a recessive gene comes from both parents (homozygous recessive) it appears to be incompatible with life. Therefore, females who inherit the affected gene will be heterozygous, and, because a normal gene is also present, the expression of the disease will be blocked. On the other hand, because males have only one X chromosome, the disease will be manifested in any male children who receive the affected gene from their mother. Such a pattern is shown in Figure 8, in 18 |P a g e NUR 1210 – MATERNAL CONCEPT (Melanie C. Tapnio, MAN, RN) Prepared by MCN FEU Faculty Lecturers January 2021  FAR EASTERN UNIVERSITY INSTITUTE OF NURSING SECOND SEMESTER – AY 2020 – 2021 NUR 1210 – NCM 109 CARE OF THE MOTHER AND CHILD AT RISK OR WITH PROBLEM which the mother has the affected gene on one of her X chromosomes and the father is disease-free: a. 50% that a male child will manifest the disease b. 50% that a female child will carry the disease gene. Figure 8. X-linked Recessive Inheritance If the father has the disease and chooses a sexual partner who is free of the disease gene, the chances are 100% that a daughter will have the sex linked recessive gene, but there is no chance that a son will have the disease (see Fig. 9). Figure 9. X-linked Recessive Inheritance 19 |P a g e NUR 1210 – MATERNAL CONCEPT (Melanie C.

Only males in the family will have the disorder. b. A history of girls dying at birth for unknown reasons often exists (females who had the affected gene on both X chromosomes). c. Sons of an affected man are unaffected. d. The parents of affected children do not have the disorder. Figure 10. Family genogram: X-linked Recessive inheritance 5. Multifactorial (Polygenic) Inheritance o Many childhood disorders such as heart disease, diabetes, pyloric stenosis, cleft lip and palate, neural tube disorders, hypertension, and mental illness tend to have a higher-than usual incidence in some families. They appear to occur from multiple gene combinations possibly combined with environmental factors. o Diseases caused by multiple factors this way do not follow Mendelian laws because more than a single gene or human lymphocyte antigen (HLA) is involved. Their incidence is so unpredictable. A family history, for instance, may reveal no set pattern. Some of these conditions have a predisposition to occur more frequently in one sex (cleft palate occurs more often in girls than boys), but they can occur in either sex. 20 |P a g e NUR 1210 – MATERNAL CONCEPT (Melanie C.

Chromosomal Abnormalities (Cytogenic Disorders) o In some instances of genetic disease, the abnormality occurs not because of dominant or recessive gene patterns but through a fault in the number or structure of chromosomes which results in missing or distorted genes. When chromosomes are photographed and displayed, the resulting arrangement is termed a karyotype. 1. Nondisjunction Abnormalities o Meiosis is the type of cell division in which the number of chromosomes in the cell is reduced to the haploid (half) number for reproduction (i.e., 23 rather than 46 chromosomes). o All sperm and ova undergo a meiosis cell division early in formation. The cell then divides cleanly, with 23 chromosomes in the first new cell and 23 chromosomes in the second new cell. o Chromosomal abnormalities occur if the division is uneven (nondisjunction). The result may be that one new sperm cell or ovum has 24 chromosomes and the other has only 22. If a spermatozoon or ovum with 24 or 22 chromosomes fuses with a normal spermatozoon or ovum, the zygote (sperm and ovum combined) will have either 47 or 45 chromosomes, not the normal 46. The following are the chromosomal abnormalities because of nondisjunction. a. Down Syndrome / Trisomy 21 syndrome (47XY21+ OR 47XX21+) a. Trisomy 21, the most frequently occurring chromosomal disorder, occurs in about 1 in 800 pregnancies. In women who are older than 35 years of age, the incidence is as 1 in 100 live births.

Management of children with trisomy 21 § Early educational and play programs so they can develop to their full capacity. § Good handwashing since they are prone to infection. § Feed slowly. The enlarged tongue may interfere with swallowing and cause choking § Physical examination at birth to enable the detection of the genetic disorder and the initiation of parental counseling, support and future planning. 22 |P a g e NUR 1210 – MATERNAL CONCEPT (Melanie C.

At puberty, the following are observed: § Small testes and produce ineffective sperm § Gynecomastia (increased breast size) § An increased risk of male breast cancer e. Turner syndrome (45XO) The child with Turner syndrome (gonadal dysgenesis) has only one functional X chromosome. The incidence is approximately 1 per 10,000 live births. The disorder can be identified during pregnancy because of the extra skin at the sides of the neck. Their other characteristics are: § Gonodal dysgenesis § Only one functional ovaries § Sterile § Secondary sex characteristics do not develop at puberty § Edema of the hands and feet § Coarctation (stricture) of the aorta § Kidney disorders § Hairline at the nape is low set § Webbed and short neck § Congenital heart defect § Severely cognitive challenged Management of a child with Turner Syndrome § Human growth hormone § Estrogen at 13 years old § To become pregnant IVF with surrogate oocyte transfer 24 |P a g e NUR 1210 – MATERNAL CONCEPT (Melanie C.

Deletion Abnormalities o Deletion abnormalities are a form of chromosome disorder in which part of a chromosome breaks during cell division, causing the affected person to have the normal number of chromosomes plus or minus an extra portion of a chromosome, such as 45.75 chromosomes or 47.5. a. Cri-du-chat syndrome (46XY5P-) - In cri-du-chat syndrome (46XY5q_), one portion of chromosome 5 is missing. § Abnormal cry (sound of a cat than human) § Small head § Wide-set eyes § Downward slant palpebral fissure of the eye § Recessed mandible § Severely cognitively challenge b. Fragile X Syndrome (46XY23Q-) - Fragile X syndrome is the most common cause of cognitive challenge in males. It is an X-linked disorder in which on long arm of an X chromosome is defective, which results in inadequate protein synaptic responses. The incidence of the syndrome is about 1 in 4,000 males. The following are the characteristics of a boy with fragile X syndrome: § Hyperactivity, aggression, or autism § Reduced intellectual functioning, with marked deficits in speech and arithmetic § Large head, long face with high forehead § Prominent lower jaw § Large protruding ears § Obesity 25 |P a g e NUR 1210 – MATERNAL CONCEPT (Melanie C.

Translocation Abnormalities o Translocation abnormalities are perplexing situations in which a child gains an additional chromosome through another route. A form of Down syndrome occurs as an example of this. o In this instance, one parent of the child has the correct number of chromosomes (46), but chromosome 21 is misplaced; it is abnormally attached to another chromosome, such as chromosome 14 or 15. o The parent’s appearance and functioning are normal because the total chromosome count is a normal 46. He or she is termed a balanced translocation carrier. o If, during meiosis, this abnormal chromosome 14 (carrying the extra 21 chromosome) and a normal chromosome 21 from the other parent are both included in one sperm or ovum, the resulting child will have a total of 47 chromosomes because of the extra number 21. Such a child is said to have an unbalanced translocation syndrome. The phenotype (appearance) of the child will be indistinguishable from that of a child with the form of Down syndrome that occurs from simple nondisjunction. 4. Mosaicism o Mosaicism is an abnormal condition that is present when the nondisjunction disorder occurs after fertilization of the ovum, as the structure begins mitotic division (in simple nondisjunction, uneven cell division occurs during meiosis. 26 |P a g e NUR 1210 – MATERNAL CONCEPT (Melanie C. Tapnio, MAN, RN) Prepared by MCN FEU Faculty Lecturers January 2021  FAR EASTERN UNIVERSITY INSTITUTE OF NURSING SECOND SEMESTER – AY 2020 – 2021 NUR 1210 – NCM 109 CARE OF THE MOTHER AND CHILD AT RISK OR WITH PROBLEM o If this occurs, different cells in the body will have different chromosome counts. The extent of the disorder depends on the proportion of tissue with normal chromosome structure to tissue with abnormal chromosome constitution. o Children with Down syndrome who have near normal intelligence may have this type of pattern. o The occurrence of such a phenomenon at this stage of development suggests that a teratogenic (harmful to the fetus) condition, such as x-ray or drug exposure, existed at that point to disturb normal cell division. This genetic pattern in a female with Down syndrome caused by mosaicism would be abbreviated as 46XX/47XX21_ to show that some cells contain 46 and some 47 chromosomes. 5. Isochromosomes o If a chromosome accidentally divides not by a vertical separation but by a horizontal one, a new chromosome with mismatched long and short arms can result. This is an isochromosome. It has much the same effect as a translocation abnormality when an entire extra chromosome exists. o Some instances of Turner syndrome (45XO) may occur because of isochromosome formation. D. Genetic Counselling and Testing It is advantageous for an individual concerned with the possibility of transmitting a disease to his or her children to ask for genetic counseling at a preconception health visit for advice on the inheritance of disease because counseling can serve to: 1. Provide concrete, accurate information about the process of inheritance and inherited disorders 2. Reassure people who are concerned that their child may inherit a particular disorder that the disorder will not occur 3. Allow people who are affected by inherited disorders to make informed choices about future reproduction 4. Allow people to pursue potential interventions that may exist such fetal surgery. 27 |P a g e NUR 1210 – MATERNAL CONCEPT (Melanie C.

Allow families to begin preparation for a child with special needs Couples who are most apt to benefit from a referral for genetic testing or counseling include: - A couple who has a child with a congenital disorder or an inborn error of metabolism. Many congenital disorders occur because of teratogenic invasion during pregnancy that has gone unrecognized. Learning that the abnormality occurred by chance rather than inheritance is important, because the couple will not have to spend the remainder of their childbearing years in fear that another child may be born with the disorder (although a chance circumstance could occur again). If a definite teratogenic agent, such as a drug a woman took during pregnancy, can be identified, the couple can be advised about preventing this occurrence in a future pregnancy. - A couple whose close relatives have a child with a genetic disorder such as a chromosomal disorder or an inborn error of metabolism. It is difficult to predict the expected occurrence of many “familial” or multifactorial disorders. In these instances, counseling should be aimed at educating the couple about the disorder, treatment available, and the prognosis or outcome of the disorder. Based on this information, the couple can make an informed reproductive choice about children. - Any individual who is a known carrier of chromosomal disorder. Understanding of his or her own chromosome structure and the process by which future children could be affected can help such an individual make an informed choice about reproduction or can alert him or her to the importance of fetal karyotyping during any future pregnancy - Any individual who has an inborn error of metabolism or chromosomal disorder. Any person with a disease should know the inheritance pattern of the disease and, like those who are balanced translocation carriers, should be aware if prenatal diagnosis is possible for his or her particular disorder. 28 |P a g e NUR 1210 – MATERNAL CONCEPT (Melanie C.

The more closely related are two people, the more genes they have in common, so the more likely it is that a recessively inherited disease will be expressed. A brother and sister, for example, have about 50% of their genes in common; first cousins have about 12% of their genes in common. - Any woman older than 35 years and any man older than 55 years. This is directly related to the association between advanced parental age and the occurrence of Down syndrome. - Couples of ethnic backgrounds in which specific illnesses are known to occur. Mediterranean people, for example, have a high incidence of thalassemia, a blood disorder; those with a Chinese ancestry have a high incidence of glucose-6- phosphate dehydrogenase (G6PD) deficiency, a blood disorder where destruction of red cells can occur IV. Nursing Process for Genetic Assessment and Counseling A. Assessment for Genetic Disorders Genetic assessment begins with careful study of the pattern of inheritance in a family. A history, physical examination of family members, and laboratory analysis, such as karyotyping or DNA analysis, are performed to define the extent of the problem and the chance of inheritance. 1. History - Diseases in family members for a minimum of three generations (include half brother and sisters or anyone related in any way as family) - Document whether the parents are consanguineous or related to each other - Include family’s ethnic back ground - Obtain as much as information by letting the couple describe the appearance or activities of affected individual or asking permission to obtain health records - Obtain an extensive prenatal history of any affected person whether environmental conditions could account for the condition. 29 |P a g e NUR 1210 – MATERNAL CONCEPT (Melanie C. Tapnio, MAN, RN) Prepared by MCN FEU Faculty Lecturers January 2021  FAR EASTERN UNIVERSITY INSTITUTE OF NURSING SECOND SEMESTER – AY 2020 – 2021 NUR 1210 – NCM 109 CARE OF THE MOTHER AND CHILD AT RISK OR WITH PROBLEM - Draw a family genogram to identify the possibility of a chromosomal disorder occurring in a particular couple’s children and identify other family member who might benefit from genetic counseling. 2. Physical Assessment Because genetic disorders often occur in varying degrees of expression, a careful physical assessment of any family member with a disorder, that child’s siblings, and the couple seeking counseling is needed. During inspection, pay particular attention to certain body areas, such as: - the space between the eyes - the height, - contour, and shape of ears - the number of fingers and toes, and the presence of webbing. - Dermatoglyphics (the study of surface markings of the skin) can also be helpful. - abnormal fingerprints or palmar creases - abnormal hair whorls or coloring of hair can also be present. Careful inspection of newborns is often sufficient to identify a child with a potential chromosomal disorder. Infants with multiple congenital anomalies, those born at less than 35 weeks’ gestation, and those whose parents have had other children with chromosomal disorders need extremely close assessment. 3. Screening and Diagnostic Testing 1. Many diagnostic tests are available to provide important clues about possible disorders. Before pregnancy, DNA analysis or karyotyping of both parents and an already affected child provides a picture of the family’s genetic pattern and can be used for prediction in future children. Once a woman is pregnant, several other tests may be performed to help in the prenatal diagnosis of genetic disorder (Table 3 and Table 4). During first trimester, women are offered a routine sonogram screening (a nuchal translucency scan) and an analysis of maternal serum levels of alpha fetoprotein (MSAFP), pregnancy- associated plasma protein A (PAPP-A), and free beta hCG to evaluate for chromosomal 30 |P a g e NUR 1210 – MATERNAL CONCEPT (Melanie C. Tapnio, MAN, RN) Prepared by MCN FEU Faculty Lecturers January 2021  FAR EASTERN UNIVERSITY INSTITUTE OF NURSING SECOND SEMESTER – AY 2020 – 2021 NUR 1210 – NCM 109 CARE OF THE MOTHER AND CHILD AT RISK OR WITH PROBLEM disorders in the fetus. Additionally, women over the age of 35 years may be offered a more accurate noninvasive blood test, circulating cell-free DNA (cfDNA) testing, to screen for chromosomal disorders. The chorionic villi sampling and amniocentesis are diagnostic tests that assess the karyotype when fetal chromosomes are photographed and displayed, which can provide a definite answer about the presences or absences of disorders. Deciding to terminate a pregnancy based on a laboratory finding is rarely easy. If a couple decides to terminate pregnancy, they need support for their decision to end the pregnancy. If they decide not to terminate the pregnancy, they may need support during the remainder of the pregnancy and in the days following birth. a. Karyotyping. For karyotyping, a sample of peripheral venous blood or a scraping of cells from the buccal membrane is taken. Cells are allowed to grow until they reach metaphase, the most easily observed phase. Cells are then stained, placed under a microscope, and photographed. Chromosomes are identified according to size, shape, and stain; cut from the photograph, and arranged. Any additional, lacking, or abnormal chromosomes can be visualized by this method. A newer method of staining, FISH, allows karyotyping to be done immediately, rather than waiting for the cells to reach metaphase. This makes it possible for a report to be obtained in only 1 day. Fetal skin cells can be obtained by amniocentesis or CVS. A few fetal cells circulate in the maternal bloodstream, most noticeably trophoblasts, lymphocytes, and granulocytes. They are present but few in number during the first and second trimesters but plentiful during the third trimester. Such cells can be cultured and used for genetic testing for such disorders as the trisomies. b. Chorionic Villi Sampling. 31 |P a g e NUR 1210 – MATERNAL CONCEPT (Melanie C. Tapnio, MAN, RN) Prepared by MCN FEU Faculty Lecturers January 2021  FAR EASTERN UNIVERSITY INSTITUTE OF NURSING SECOND SEMESTER – AY 2020 – 2021 NUR 1210 – NCM 109 CARE OF THE MOTHER AND CHILD AT RISK OR WITH PROBLEM CVS is a diagnostic technique that involves the retrieval and analysis of chorionic villi from the growing placenta for chromosome or DNA analysis. The test is highly accurate and yields no more false-positive results than does amniocentesis. Although this procedure may be done as early as week 5 of pregnancy, it is more commonly done at 8 to 10 weeks. With this technique, the chorion cells are located by ultrasound. A thin catheter is then inserted vaginally, or a biopsy needle is inserted abdominally or intravaginally, and a number of chorionic cells are removed for analysis (Fig. 11). CVS carries a small risk (less than 1%) of causing excessive bleeding, leading to pregnancy loss. There have been some instances of children being born with missing limbs after the procedure (limb reduction syndrome). This has occurred with a high enough frequency that women need to be well informed of these risks beforehand. After CVS, instruct a woman to report chills or fever suggestive of infection or symptoms of threatened miscarriage (uterine contractions or vaginal bleeding). Women with an Rh-negative blood type need Rh immune globulin administration after the procedure to guard against isoimmunization in the fetus. The cells removed in CVS are karyotyped or submitted for DNA analysis to reveal whether the fetus has a genetic disorder. Because chorionic villi cells are rapidly dividing, results are available quickly, perhaps as soon as the next day. If a twin or multiple pregnancy is present, with two or more separate placentas, cells should be removed separately from each placenta. Because fraternal twins are derived from separate ova, one twin could have a chromosomal abnormality while the other does not. Not all inherited diseases can be detected by CVS. Be certain that parents understand that only those disorders involving abnormal chromosomes or nondisjunction, and those whose specific gene location is known, can be identified by CVS. The test is not apt to reveal the extent of spinal cord abnormalities, for example. 32 |P a g e NUR 1210 – MATERNAL CONCEPT (Melanie C.

Since the villi arise from trophoblast cells, their chromosome structure is the same as in the fetus. c. Amniocentesis. Amniocentesis is the withdrawal of amniotic fluid through the abdominal wall for analysis at the 14th to 16th week of pregnancy. Because amniotic fluid has reached about 200 mL at this point, enough fluid can be withdrawn for karyotyping of skin cells found in the fluid as well as an analysis of AFP or acetylcholinesterase. If no acetylcholinesterase, a breakdown product of blood, is found in the specimen, it confirms that an elevated AFP level is not a false-positive reading caused by blood in 33 |P a g e NUR 1210 – MATERNAL CONCEPT (Melanie C. Tapnio, MAN, RN) Prepared by MCN FEU Faculty Lecturers January 2021  FAR EASTERN UNIVERSITY INSTITUTE OF NURSING SECOND SEMESTER – AY 2020 – 2021 NUR 1210 – NCM 109 CARE OF THE MOTHER AND CHILD AT RISK OR WITH PROBLEM the fluid. For the procedure, a pocket of amniotic fluid is located by ultrasound. Then a needle is inserted transabdominally, and about 20 mL of fluid is aspirated. Skin cells in the fluid are karyotyped for chromosomal number and structure. The level of AFP is analyzed. Some disorders, such as Tay-Sachs disease, can be identified by the lack of a specific enzyme, such as hexosaminidase A, in amniotic fluid. Amniocentesis has the advantage over CVS of carrying only a 0.5% risk of spontaneous miscarriage. Unfortunately, it usually is not done until the 14th to 16th week of pregnancy. This may prove to be a difficult time because, by this date, a woman is beginning to accept her pregnancy and bond with the fetus. In addition, termination of pregnancy during the second trimester is more difficult than during a first trimester. Support women while they wait for test results and to make a decision about the pregnancy. Women with an Rh-negative blood type need Rh immune globulin administration after the procedure to protect against isoimmunization in the fetus. All women need to be observed for about 30 minutes after the procedure to be certain that labor contractions are not beginning and that the fetal heart rate remains within normal limits 34 |P a g e NUR 1210 – MATERNAL CONCEPT (Melanie C.

Nursing Diagnosis Typical nursing diagnoses related to the area of genetic disorders include: 1. Decisional conflict related to testing for an untreatable genetic disorder 2. Fear related to outcome of genetic screening tests 3. Situational low self-esteem related to identified chromosomal abnormality 4. Deficient knowledge related to inheritance pattern of the family’s inherited disorder 5. Health-seeking behaviors related to potential for genetic transmission of disease 6. Altered sexuality pattern related to fear of conceiving a child with a genetic disorder C. Outcome Identification and Planning Outcome identification and planning for families undergoing genetic assessment differ according to the types of assessments performed and the results obtained. This may include determining what information the couple needs to know before testing can proceed or helping couples arrange for further assessment measures. Be certain that goals are realistic and consistent with the individual’s or couple’s lifestyle (not all people want to be totally informed about family illnesses). 39 |P a g e NUR 1210 – MATERNAL CONCEPT (Melanie C.

Implementation Parental reactions to the knowledge that their child has a possible genetic disorder or to the birth of a child with a genetically inherited disorder usually involves a grief reaction, similar to that experienced by parents whose child has died at birth (their “perfect” child is gone). Both parents may pass through stages of: 1. Shock and denial (“This cannot be true”), 2. Anger (“It’s not fair that this happened to us”), 3. Bargaining (“If only this would go away”) 4. Acceptance (“It has happened to us and it is all right”). For some couples, a genetic disorder is diagnosed during the pregnancy; for others, it may not be discovered until birth, or possibly not even until the child is of school age. For these parents, the reaction will occur at that later point of diagnosis. E. Outcome Evaluation Examples of expected outcomes for a family with a known genetic disorder might be: 1. Couple states they feel capable of coping no matter what the outcome of genetic testing. 2. Client accurately states the chances of a genetic disorder occurring in her next child. 3. Couple states they have resolved their feelings of low self-esteem related to birth of a child with a genetic disorder. A couple’s decisions about genetic testing and childbearing can change over time. For example, a decision made at age 25 not to have children because of a potential genetic disorder may be difficult to maintain at age 30, as the couple sees many of their friends with growing families. Be certain that such couples have the telephone number of a genetic counselor. Urge them to call periodically for news of recent advances in genetic screening techniques or disease treatments so they can remain current and well informed for future planning. 40 |P a g e NUR 1210 – MATERNAL CONCEPT (Melanie C.
