Study Notes on Nursing and Maternal Health
Advanced Nursing Roles
Nurse Practitioner (NP)
Has a Doctorate of Nursing Practice (DNP) or master's degree.
Provides ambulatory care services.
Title is determined by the area of specialization, e.g., Family NP, Pediatric NP, Psychiatric NP.
Clinical Nurse Specialist (CNS)
Holds a master’s degree.
Possesses specialized knowledge and competence in a specific area.
Commonly found in:
Mother-baby units
Pediatric units
Intensive care units assisting staff in providing excellent evidence-based care; focuses on improving patient outcomes through evidence-based practice, staff education, and consultation.
Certified Nurse Midwife (CNM)
Educated in nursing and midwifery, certified by the American College of Nurse Midwives (ACNM).
Independently manages the care of women at low risk for complications during pregnancy and birth, as well as the care of healthy newborns. Provides comprehensive well-woman care, family planning, preconception care, and care during labor, birth, and the postpartum period.
Nurse Researcher
Holds a doctoral degree, typically a PhD.
Plays a leadership role in creating new research, generally within a university setting.
Key role in advancing evidence-based practices that improve patient outcomes and the quality of patient care.
Informed Consent
Definition: For a nurse to touch a person without consent is considered battery. Battery refers to the unlawful touching of another person without their consent.
Consent is not informed unless the patient or guardian understands:
Procedures or treatments involved
The rationale and benefits of each alternative treatment
Any associated risks.
This includes explaining risks, benefits, and alternatives in a language the patient understands, ensuring voluntary decision-making, and verifying competency. Consent is generally obtained by the healthcare provider performing the procedure, but the nurse's role is to ensure the patient understands the information and to witness the signature.
In many states, a pregnant teenager is considered emancipated and can consent independently if they are a parent or pregnant. In some states, other criteria for emancipation might apply, allowing minors to consent, such as living independently or being married.
After obtaining consent, the nurse documents the teaching and learning outcomes in the patient's record.
Types of Families
Types of Family Structures:
Nuclear Family: Parents and children. Often referred to as the traditional family unit.
Childfree Family: Couples without children. Couples who choose not to have children or are unable to, focusing on their relationship and other life pursuits.
Extended Family: Includes relatives like grandparents, aunts, uncles. Provides significant social and economic support.
Extended Kin Network Family: Two nuclear families living near each other and helping each other. Members often share chores, resources, and child-rearing responsibilities.
Single Parent Family: Single parent (mother or father) raising children. Can arise from divorce, separation, death of a partner, or intentional single parenthood; faces unique financial and emotional challenges.
Blended Family: Parents with children from previous relationships. Requires adaptation and adjustment from all members to integrate traditions and parenting styles.
Binuclear Family: Co-parenting arrangements where children live in two houses. Children maintain significant relationships with both parents and their respective extended families.
Heterosexual Cohabitating Family: Unmarried couples living together who may have children. May choose this arrangement for various reasons, including financial, emotional, or as a step before marriage.
Gay/Lesbian Family: Same-sex parents raising children. May involve biological, adoptive, or foster children; often face societal challenges but build strong family units.
Transfamily: Families with transgender members. Focuses on supporting the gender identity and expression of its transgender members, which can profoundly impact family dynamics.
Cultural Influences on Families:
Families come together with a combination of knowledge, beliefs, and behaviors.
Teaching highlights should include:
Involvement of grandparents in cultural health practices. Emphasize respecting diverse cultural practices in health care, especially regarding decision-making and healing methods.
Signs of Illness in Newborns: Need for immediate follow-up care, such as fever, poor feeding, lethargy, difficulty breathing, jaundice, or unusual cries, require immediate medical attention.
Safety Alert
Use of Herbs and Natural Products: Raises many issues; individuals interested in using herbs are advised to consult their healthcare provider before taking. Many herbs can interact negatively with prescription medications, alter drug metabolism, or have unknown effects on pregnancy, lactation, or children. Lack of regulation means purity and dosage can also be inconsistent.
Genetic & Genomic Influences in Maternal, Newborn, & Child Health
Monosomy: Missing one chromosome (e.g., Turner syndrome, where the individual has ).
Trisomy: One extra chromosome (e.g., Down syndrome, where the individual has or ).
Inheritance Patterns:
Autosomal Dominant: One gene is sufficient to cause a disorder. The abnormal gene dominates the normal gene, so only one copy of the defective gene is needed to cause the disorder. Affects males and females equally, and a child has a 50% chance of inheriting the disorder if one parent is affected.
Autosomal Recessive: Requires two alleles to express the disorder; involves one dominant and one recessive allele. Requires two copies of the abnormal gene (one from each parent) for the disorder to be expressed. Carriers have one copy but do not show symptoms. If both parents are carriers, there is a 25% chance of the child inheriting the disorder.
Examples:
Achondroplasia: A form of dwarfism caused by one bad allele, a mutation in the FGFR3 gene, affecting bone growth.
Neurofibromatosis (NF1): Variable expression of the disorder; a genetic disorder causing tumors to grow on nerve tissue.
Sickle Cell Disease: Affects hemoglobin and leads to vaso-occlusive events and chronic anemia. An autosomal recessive disorder; a single point mutation in the beta-globin gene leads to abnormal hemoglobin (hemoglobin S), causing red blood cells to become stiff and sickle-shaped.
X-Linked Conditions: Genetic conditions associated with an allele on the X chromosome; examples include Hemophilia A. Primarily affect males because they have only one X chromosome. Females are typically carriers and are less severely affected or asymptomatic. Other examples include Duchenne Muscular Dystrophy, Fragile X syndrome.
Diagnostic Testing
Prenatal Testing: Invasive diagnostic tests should be available for abnormal findings, particularly before 20 weeks of pregnancy. Invasive tests like chorionic villus sampling (CVS) (typically 10-13 weeks) and amniocentesis (typically 15-20 weeks) are used to diagnose chromosomal abnormalities, genetic disorders, and sometimes neural tube defects, following abnormal screenings or high-risk indicators.
Genetic Testing Goals: To develop effective treatment plans, psychosocial support, referrers to genetic specialists. Includes providing accurate diagnosis, clarifying prognosis, facilitating informed reproductive decisions, and offering tailored support.
Indicator of Genetic Conditions: Noticing multiple minor anomalies in a newborn can signal major anomalies, warranting genetic referral. Minor anomalies include unusual hair whorls, single palmar creases, ear tags, or unusual facial features.
Health Promotion
Who Needs Preconceptual or Prenatal Genetic Counseling:
Women aged 35 or over at the time of birth.
Individuals with known genetic disorders or a family history of them.
Individuals with a previous child with a genetic disorder or birth defect, those with a history of recurrent miscarriages or stillbirths, and certain ethnic groups with higher incidences of specific genetic conditions.
Contraception
Fertility Awareness Based Methods (FAB): Natural family planning methods focusing on monitoring the fertile window. Examples include the calendar rhythm method, basal body temperature (BBT) method, and cervical mucus method (Billings Ovulation Method), which track physiological changes to identify the fertile window. Requires consistent self-monitoring and can be less effective than hormonal or LARC methods.
Barrier Methods:
Effective for preventing pregnancies when used correctly, may include male and female condoms, diaphragms, and cervical caps. Mechanism involves physically blocking sperm from reaching the egg. Efficacy varies with correct and consistent use. Condoms also offer protection against STIs.
Long-Acting Reversible Contraception (LARC):
Intrauterine contraception effective for 3-10 years.
Nexplanon contraceptive lasts for 3 years. Highly effective, convenient, and reversible contraceptive options. Examples include copper IUDs (e.g., Paragard) and hormonal IUDs (e.g., Mirena, Skyla), and the contraceptive implant (Nexplanon).
Pregnancy Health Promotion: Domestic Violence and Assault
Prevalence of Domestic Violence: Nearly 1 in 5 women experience severe physical violence in their lives. It is crucial for healthcare providers to screen all women for domestic violence, as pregnancy can sometimes be a trigger or intensify existing abuse.
Cycle of Violence Phases: Includes tension-building, acute battering, and the loving phase. Understanding these phases ('tension escalates,' 'abuser lashes out,' 'period of remorse/honeymoon phase') helps in identifying patterns and providing effective support and safety planning.
Common Gynecologic Problems
Bacterial Vaginosis: Characterized by discharge with a foul odor, treated with Metronidazole. Caused by an imbalance of normal vaginal bacteria, leading to an overgrowth of certain bacteria. The foul odor is often described as 'fishy,' especially after intercourse or douching. Treatment with Metronidazole (oral or vaginal gel).
Genital Herpes: Symptoms include blister-like lesions. A viral infection caused by the herpes simplex virus (HSV-1 or HSV-2). Symptoms include painful, itchy blister-like lesions on the genitals, buttocks, or inner thighs, often preceded by tingling or burning sensations. It is a recurring condition with no cure, but antiviral medications can manage outbreaks.
Reproductive Physiology, Conception, & Fetal Development
Female Hormones: Estrogens and progesterone contribute to pregnancy maintenance and organize reproductive functions. Estrogens, primarily estradiol, are responsible for the development of female secondary sexual characteristics and play a crucial role in regulating the menstrual cycle and preparing the uterus for pregnancy. Progesterone is vital for maintaining pregnancy by thickening the uterine lining, relaxing uterine muscles, and preventing premature contractions.
Stages of Fertilization and Development:
Fertilization: The fusion of sperm and egg, usually occurring in the fallopian tube, forming a zygote.
Pre-embryonic stage (first 2 weeks): Involves rapid cell division, implantation in the uterine wall, and the formation of embryonic membranes and primary germ layers (ectoderm, mesoderm, endoderm).
Embryonic stage (weeks 3-8): Critical period of organogenesis, where major body structures and internal organs develop. Exposure to teratogens during this stage can cause significant birth defects.
Fetal stage (week 9 to birth): Period of rapid growth and maturation of organ systems, including the brain, lungs, and digestive system.
Assessment of Pregnancy
Significant Changes in Pregnancy:
Weight gain recommendations vary based on pre-pregnancy BMI:
Underweight: 28-40 lbs
Normal weight: 25-35 lbs
Overweight: 15-25 lbs
Obese: 11-20 lbs. These guidelines aim to optimize maternal and fetal health outcomes, with excessive or insufficient weight gain associated with various risks.
Diagnostic Tests in Pregnancy: Screening for conditions like gestational diabetes, hemoglobin disorders, and STIs. Includes routine blood tests (CBC, blood type, Rh factor, syphilis, hepatitis B, HIV), urinalysis, ultrasound for dating and fetal anatomy, gestational diabetes screening (GTT) around 24-28 weeks, and Group B Streptococcus (GBS) screening around 35-37 weeks.
Warning Signs in Pregnancy:
Sudden gush of fluid, vaginal bleeding, severe abdominal pain, dizziness, and significant changes in fetal movement. These signs warrant immediate medical attention as they may indicate serious complications such as preterm labor, placental abruption, preeclampsia, or fetal distress. Nurses play a crucial role in patient education regarding recognition and prompt reporting of these signs.
Teaching Highlights
Exercise & Nutrition Guidelines for Pregnant Women: Regular exercisers may continue high-intensity programs; newly active women should gradually increase exercise, focusing on low-impact options. Regular exercise can improve mood, reduce back pain, and prepare the body for labor. Avoid activities with a high risk of falling or abdominal trauma. Listen to your body and stay hydrated.
Nutrition: Emphasize a balanced diet rich in fruits, vegetables, lean proteins, and whole grains. Key nutrients include folic acid (to prevent neural tube defects), iron (to prevent anemia), calcium, and Vitamin D. Advise against raw fish, unpasteurized dairy, and excessive caffeine. Supplementation with prenatal vitamins is usually recommended.
Conclusion
Continued education and advocacy are critical for enhancing reproductive health outcomes for women, newborns, and children throughout different family structures and societal challenges.
