PPN 301 Class 3: Pregnancy at Risk: Social & Physiological Factors Age Considerations: Adolescent Pregnancy Risk Impact of adolescent Adolescent individuals (ages 10 to 19 Pregnancy years) are at increased risk for Social factors Meeting developmental eclampsia, puerperal endometritis, and systemic infections milestones Still developing own Maternal mortality Perinatal complications are the independence Social isolation leading cause of death for 15 to 19 Lack of social support years-old girls globally Fear of child services Early pregnancy or marriage cause Stigma (actual & perceived) an estimated 5 to 33% of girls (aged Need to be perceived as a 15 to 24 years) to drop out of school “good mother” (World Bank, 2017). Even if this means not asking for help/staying with a non-supportive partner/not Adolescent Friendly Perinatal Care See: NFB video- bridge film: Unxpected https://www.nfb.c a/film/unexpecte d https://www.nfb.ca/film/unexp Age Considerations: Advance Maternal Age Pregnancy > 35 years Increased risk of: Maternal death (even higher over 40) Miscarriage Stillbirth Preterm Low birth weight Perinatal mortality Down syndrome Despite higher risk, overall risks are still low for women who are healthy, and free of pre-existing disease What are the reasons people delay pregnancy and parenthood? https://dudemom.com/advanced-maternal-age-35-pregnant/ Women with Disabilities Higher risk for social, economic & physical problems Stigma/assumptions of care providers & family Higher risk for social service involvement Need for pre-planning, social support Think about: How can a CHN’s assumptions & biases affect care for a pregnant woman with disabilities? What should a CHN assess when working with a pregnant woman with physical disability? Developmental/cognitive disability? How could a CHN support a pregnant woman with physical disability? Developmental/cognitive disability? Intimate Partner Violence and Pregnancy People at risk during pregnancy: Pre-pregnancy abuse Women under 25 Substance use by woman or partner Single or lone parents Recently separated or process of ending a relationship Indigenous women Women with disability Lesbian, bisexual, transgendered Low SES Associated with preterm labour, prematurity, LBW, Neonatal & infant/maternal mortality IPV Screening Tools RADA R Tool HITS Tool (Deshpande & Lewis-O'Connor, Role of CHN and IPV uty to report if there is a child under 16 in house More likely to disclose if she feels comfortable & trusts CHN Show that you believe the woman Reassure that there is help Do NOT JUDGE: Leaving an abusive relationship is a process that takes time Reinforce that abuse is not her fault; abuse is a crime Reinforce that partner’s apologies will not end the abuse Explain (without blaming) that abuse affects the developing fetus & other children in the house Reinforce that woman’s safety is paramount; ask if you can consult with local police if risk of immediate danger is support Explore immediate concerns & needs to develop a plan of action Offer referral, provide information, leave numbers of resources Document interaction Application A person comes to your clinic with their partner who insists on being present during prenatal visits. You suspect that the client is being abused. What would be the best approach to use? A. Confront the partner with your suspicions B. Ask the client, in front of their partner, if they are afraid of their partner C. Try to have a colleague engage the partner outside the room so that you can broach the subject of abuse D. Tell the partner to go outside as you want to talk to the client alone Substance Use During Pregnancy Alcohol and other drugs can easily pass from mother to baby through the placenta. Cocaine, heroin, Met, Alcohol Poses a serious health risk: Bleeding complications Miscarriage Stillbirth Prematurity Low birth weight Sudden infant death syndrome Congenital anomalies (Basso, 2022b; Rutman et al., 2020) Substance Use During Pregnancy May result in lack of prenatal care Barriers to treatment Guilt, fear, shame, fear of losing custody of child Substance-use treatment programs usually do not address issues affecting pregnant women. Long waiting lists for treatment and lack of women-only recovery spaces are further barriers to treatment. Legal considerations Non-judgemental and person-centred approach Harm reduction model Nurses should encourage prenatal care, counselling, and treatment Drug testing during pregnancy No legal requirement in Canada Substance Use - Nursing Care Assess for a history of violence, abuse, and mental health concerns, poverty and lack of housing and social supports Ensure confidentiality Non-judgemental, trauma-informed approach Harm reduction: supporting a patient's desire to stop using as well as assisting them in reducing risks Person-focused framework Women are more receptive to making lifestyle changes during pregnancy than at any other time. Opioid agonist therapy (OAT) – methadone or buprenorphine treatment recommended Cannabis users need to be educated on the effects of cannabis use in pregnancy Maternal–infant attachment Breastfeeding Discharge planning Postpartum follow-up visits Application You are a nurse working with a client who continues to smoke during pregnancy. You know that this has implications for the baby. What would be the best approach to address the issue of smoking during pregnancy? A. Advise the client to request the “patch” from their doctor B. Tell client that smoking is dangerous as it may cause preterm birth or a baby that is small for gestational age. C. Explore ways in which the client can reduce the amount they smoke during pregnancy. D. Tell the client’s doctor that the client is continuing to smoke despite the risks. Early Pregnancy Bleeding Types of pregnancy loss: Miscarriage (spontaneous abortion): Loss of A: Threatened pregnancy before 20 weeks gestation or less than B: Inevitable C: Incomplete 500-g fetal weight D: Complete E: Missed Incidence – 10-15% pregnancies. 80% occurs before 12 weeks of gestation Early loss: before 12 weeks Majority related to chromosomal abnormalities, teratogenic drugs, faulty implantation, maternal abnormalities of reproductive tract, cervical insufficiency, placental abnormalities, chronic maternal illness, endocrine imbalances (hypothyroidism, DM etc), maternal infections e.g. varicella, malaria Late loss: 12-20 weeks Assessment and care Early Pregnancy Initial/general assessment Confirmation of pregnancy with Vital signs laboratory testing Number of pregnancies, number of Bleeding (bright or dark, spotting or live births continuous) Last menstrual period/estimated Pain (type, intensity, location, date of birth persistence) Pregnancy history (previous and Vaginal discharge current) Late Pregnancy Allergies Estimated date of birth Nausea and vomiting Bleeding (amount, pinky, menstrual- Pain (onset, quality, precipitating like, heavy) event, location) Pain (location, severity, intermittent, Bleeding or coagulation issues continuous) Level of consciousness Vaginal discharge Emotional status and need for Amniotic membrane status (Basso, Uterine activity support Management of Incomplete Expectant management: allows miscarriage to expel on its own. Nearly 50% of patients will miscarry on their own within 2 weeks of a diagnosis of pregnancy demise in the first trimester. Medical management: involves the use of 2-drug combination Mifepristone helps to prepare your uterus for miscarriage Misoprostol is given 24-48 hours later which helps the cervix soften and dilate to expedite the miscarriage. Surgical management: Dilation and curettage (D&C) is a surgical procedure in which the cervix is gently opened (dilation) and the pregnancy is removed with a suction device (curettage) Discharge Teaching After Pregnancy Loss Advise the patient to report any heavy, profuse, or bright red bleeding A scant, dark discharge may persist for 1 to 2 weeks. Avoid putting anything into the vagina for 2 Acknowledge the patient loss. Encourage client to speak with family and weeks or until bleeding has stopped (e.g., no tampons, no vaginal intercourse). seek support from friends. Take antibiotics as prescribed.

Non-Stress Test A nonstress test (NST) is used to measure the fetal Reactive/Normal nonstress test. (Fetal heart rate accelerations with fetal heart rate in response to the movement of the movement) fetus Involves monitoring of fetal heart rate in response to the fetal movements using electronic fetal monitor. Heart rate of a healthy fetus should increase when the fetus moves. Reactive (normal)- at least two FHR accelerations lasting at least 15 seconds and rising at least 15 beats/minute above the established baseline heart rate. Non-reactive/abnormal Nonreactive- lacks sufficient fetal heart rate nonstress test accelerations over a 40-minute period. (no fetal heart rate accelerations). Biophysical Profile - BPP Indications The pregnancy has gone past Recommended for women at increased risk 40 weeks gestation of problems that could lead to complications or pregnancy loss. Multiple gestation pregnancy The test is usually done after week 32 of Previous Stillbirth pregnancy but can be done when Polyhydramnios or pregnancy is far enough along for delivery to be considered — usually after week 24. Oligohydramnios Non-invasive test using ultrasound and fetal Gestational Diabetes (GDM) heart monitoring. Preeclampsia or other A low score on a biophysical profile might hypertensive disorder in indicate that further testing is needed. In pregnancy some cases, early or immediate delivery IUGR might be recommended. Other Pregnancy (Watts, 2022) Complications Bio-physical Profile Indications Five components of the biophysical profile are as follows: nonstress test fetal breathing movements (one or more episodes of rhythmic fetal breathing movements of 30 seconds or more within 30 minutes) fetal movement (three or more discrete body or limb movements within 30 minutes); fetal tone (one or more episodes of extension of a fetal extremity with return to flexion, or opening or closing of a hand determination of the amniotic fluid volume (a single vertical pocket of amniotic fluid exceeding 2 cm is considered evidence of adequate amniotic fluid). Each components is given a score of 2 (normal or present or 0 (abnormal, absent or insufficient). Biophysical Profile Scoring Contraction stress test (CST) Contraction stress test (CST) Use to measure the response of the fetus (FHR) after the uterus is stimulated to contract Is done to ensure during labor the fetus can handle contractions and get the oxygen needed from the placenta. Procedure: Negative contraction stress Nipple-stimulated contraction test test Oxytocin-stimulated contraction test (normal external fetal heart rate Interpretation tracing Negative test: FHR does not show deceleration or late decelerations Positive test: FHR is showing decelerations and late decelerations Indicated when there is abnormal nonstress test or biophysical profile. Provides a warning of fetal compromise than NST Positive contraction stress test (late decelerations with uterine contractions Ultrasound for Fetal Well-Being Biophysical profile (BPP) Assesses fetal breathing movements, fetal movements, fetal tone, and AFV Amniotic fluid volume (AFV) Abnormalities in AFV are frequently associated with fetal disorders. Oligohydramnios (less than 300 mL of amniotic fluid, associated with fetal renal abnormalities polyhydramnios (more than 2 L of amniotic fluid, associated with gastrointestinal and other malformations) Nursing Role in Antepartum Assessment for Risk Psychological considerations Patients undergoing antenatal assessments are anxious. Tests may show suspected fetal compromise, deterioration of maternal condition, or both. Third-trimester patients are concerned about protecting themselves and their fetuses and consider themselves vulnerable and can lead to ambivalence. When a patient is diagnosed with high-risk pregnancy, they and their family will likely experience stress related to the diagnosis. The patient may exhibit various psychological responses: Anxiety Low self-esteem and guilt Frustration Inability to function References All images, except as noted, Images: @ CC Unsplash Basso, M.
