Antepartal Period Quiz

Antepartal Period

Normal Pregnancies

• Subjective Signs and Symptoms of Pregnancy*
• Amenorrhea: Absence of menstruation typically occurs; fertilization takes place in the fallopian tube, with the egg fertile for 12-24 hours.
• Nausea & Vomiting: Commonly known as morning sickness, it typically begins around 6 weeks after the last menstrual period and can last 6-12 weeks.
• Fatigue: Increased exhaustion during the first trimester; rest and activity modification are essential.
• Breast Changes: Hormonal alterations lead to growth and sensitivity, usually beginning before missed period; breasts can increase by one cup size.
• Abdominal Enlargement: First trimester shows little abdominal change; noticeable growth occurs as the uterus rises into the abdomen.
• Urinary Frequency: Increased urge due to pressure on bladder; symptoms may return in the third trimester.
• Objective Changes*
• Pregnancy Tests*
• Urine Tests: Detect hCG; home tests are most accurate at 1-2 weeks after missed period.
• Serum Tests: More precise than urine, can detect hCG earlier; monitoring progesterone can indicate pregnancy viability.
• Fundal Height*
• Palpation of the uterine fundus begins at 10-12 weeks; height corresponds to weeks of gestation from about 16 to 36 weeks.
• Variations in fundal height may suggest multiple births or abnormalities in fetal presentation.
• Maternal Psychosexual Changes*
• First Trimester: Women may experience stress and anxiety; partner involvement is crucial for support.
• Second Trimester: Body image issues may affect intimacy; encourage communication about sexual health.
• Third Trimester: Decline in sexual interest due to body discomfort and fear of labor; reassurance is important.
• Paternal Psychosexual Changes*
• First Trimester: Fathers may feel excitement but can also feel excluded; understanding mood swings is key.
• Second Trimester: Connection may deepen with involvement in prenatal activities; anxiety about responsibilities may arise.
• Third Trimester: Concerns about labor and delivery increase; physical symptoms like insomnia may manifest.

Developmental Tasks of Becoming Parents

• Ambivalence to Acceptance*
• Common feelings of ambivalence regarding body image, sexual attractiveness, and mood swings during pregnancy.
• Acceptance often occurs by the third trimester as mothers adjust to their changing bodies.
• Preparation of Siblings*
• Preparing siblings for a new infant can help mitigate anxiety and rivalry; activities include early education and participation in family preparations.
• Preparation of Grandparents*
• Grandparents may have varying reactions; their support is beneficial but boundaries in decision-making are important.

Health Promotion

• Rest and Fatigue Management*
• Adequate sleep (8-10 hours) is vital; naps and adjusted schedules can help combat fatigue.
• Encourage gentle activities and healthy eating.
• Daily Living Activities*
• Bathing: Daily cleansing is encouraged; safety measures are important in the third trimester.
• Dressing: Comfortable, non-constrictive clothing is recommended, with avoidance of restrictive girdles.
• Exercising: Moderate exercise for 30 minutes daily is beneficial; avoid supine positions during second and third trimesters.

Nutritional Needs

• Dietary Guidelines*
• Increased caloric needs for pregnancy: 300 extra calories for singles, 600 for twins.
• Recommended intake of vitamins and minerals to support fetal development includes folic acid, calcium, vitamins A, C, D, E, and K.
• Maternal Malnutrition*
• Inadequate nutrition can affect fetal development and lead to complications; recommended weight gain varies by pre-pregnancy weight status.
• Vitamin and Mineral Deficiencies*
• Important for fetal health; deficiencies in thiamine, folic acid, Vitamin D, and calcium can lead to severe health issues for infants.
• Folic Acid is crucial for DNA synthesis and cell division; women should take 0.4mg daily, especially important prior to and during early pregnancy.
• Infants of Obese Women*
• May face complications such as macrosomia, fetal distress, and delivery issues. Close monitoring is essential.### Folic Acid Deficiency
• Folic acid levels vary significantly with diet, complicating diagnosis.
• Insufficient intake leads to nausea, vomiting, reduced appetite, and low hemoglobin in women.
• Deficiency is linked to serious neural tube defects in fetuses, including myelomeningocele, spina bifida, and anencephaly.

Iron Requirements During Pregnancy

• Essential for red blood cell production; increased plasma volume (up to 50%) results in lowered hematocrit levels (from 38-47% to as low as 34%).
• Daily iron recommendations:
  • Normal hematocrit: 30 mg elemental iron
  • Maternal iron deficiency anemia: 60-120 mg until normalization, then reduce to 30 mg daily.
• Low hemoglobin (<11 g/dL) elevates risks of infection, pre-eclampsia, and postpartal hemorrhage, which can endanger the fetus.
• Severe anemia (<6 g/dL) can lead to maternal cardiac failure and increase miscarriage, stillbirth, low birth weight, and neonatal death rates.

Fetal Development Timeline: Conception to 12 Weeks

• Embryonic stage begins 15 days post-conception; organ formation starts, making the fetus vulnerable to teratogenic agents.

Week-by-Week Development

• Week 3: Major tube structures developing (brain, spinal cord, GI system); risk of limb congenital absence.
• Week 4: Heart beats regularly; arm, leg, and tail buds appear; early eyes and ears forming; teratogenic risks include omphalocele and tracheoesophageal fistula.
• Week 5: Eyes and nasal pits present; limb development progresses with paddle-like hands/feet; teratogens may lead to cataracts and facial clefts.
• Week 6: Full arms and legs with digit formation; development of jaws and mouth; heart has chambers; teratogenic risks include cleft lip and septal defects.
• Week 7: Head rounding, eyes becoming closer together; notable fetal heartbeats; risk of significant anomalies such as intraventricular septal defects.
• Week 8: The embryo reaches 3 cm; human resemblance begins; long bones develop; risks include persistent atrial septal openings.
• Weeks 9-12: Transition to fetus; reaching 5 cm in length by week 9 and 8 cm by week 12; visible facial features, functioning movements, and developing urinary system; risk of complications decreases as vital structures mature.

Later Development: Weeks 13-16

• Growth spurt, gender differentiation becomes apparent; skin transparent, vascular structures are evident; involves rapid development in other bodily systems.

Important Milestones: Weeks 24 to 40

• Week 24: Fetus measures 28 cm, weighs 780 g; lungs developing; noticeable reflexes; distinguished skin features.
• Weeks 25-28: Central nervous system maturation; eyelids functioning; significant lung development aids potential for premature viability.
• Weeks 29-32: Increased weight (up to 2000 g); muscle and fat accumulation; lung development still maturing.
• Weeks 35-36: Smooth skin, significant fat development; preparation for successful birth increases with neurological and respiratory maturation.
• Weeks 38-40: Full-term definitions including size (48-52 cm, 3000-3600 g); preparations for delivery, with adequate antibody transfer from mother.

Intrauterine Growth Restriction (IUGR)

• Diagnosis occurs when fetal growth potential is not fulfilled; assessed via prenatal ultrasound.
• Associated conditions include oligohydramnios and pre-eclampsia.
• Types of IUGR:
  • Symmetric: Smaller overall size, often due to early pregnancy complications like chromosomal abnormalities.
  • Asymmetric: Disproportionate head size; usually develops later in pregnancy, often linked to maternal factors.
