Study Notes
Definitions and Concepts
- Gestation: The period from fertilization to delivery, typically lasting around 40 weeks.
- Prenatal Care: Healthcare provided to a woman during pregnancy, aimed at maximizing health for both mother and baby.
- Gravida: Refers to a woman who is pregnant.
- Abortion: Termination of pregnancy before viability (24 weeks AOG or 400 grams); can be spontaneous or therapeutic.
- TPAL Approach: A system to summarize pregnancy history—T (term births), P (preterm births), A (abortions), L (living children).
Risk Factors in Pregnancy
-
High-Risk Indicators: Factors negatively impacting pregnancy outcomes include:
- Low income/education
- Poor diet
- High altitude living
- Multiple pregnancies (>3)
- Weight extremes (over 200 lbs or under 100 lbs)
- Age (≥35 years)
- Substance abuse (drugs, smoking, alcohol)
- Medical conditions (anemia, hypertension, diabetes)
Pregnancy Testing Methods
- Radio-receptor Assay (RRA): Identifies HCG in blood within 1 hour.
- Radioimmunoassay (RIA): Detects HCG within 1-3 hours; reliable pregnancy detection about 6 days post-conception.
- Enzyme-Linked Immunosorbent Assay (ELISA): Highly sensitive urine test for HCG, results in 4 minutes.
Measurement of Expected Delivery
- EDD Calculation: Various rules (Nagele's, McDonald's, Johnson’s) are used to estimate the expected date of delivery.
Danger Signals in Pregnancy
- Fever and Chills: May indicate intrauterine infection.
- Vaginal Bleeding: Should be reported regardless of severity; any unusual symptoms warrant notification.
Teratogens and Their Impact
-
Teratogens: Factors that can cause developmental malformations. Their effects can include:
- Physical and cognitive impairments.
- Growth restrictions.
-
Potential Teratogenic Features:
- Mental and motor development issues, eye defects, and hearing impairments.
- Certain vaccines (e.g., live virus vaccines) are contraindicated during pregnancy due to risk of fetal infection.
Fetal Development Timeline
- First Lunar Month: Heart starts to beat by the end of the 4th week; limbs and lungs begin forming.
- Two Lunar Months: More distinct head and external genitalia; amniotic fluid surrounds the embryo.
- Five Lunar Months: Brown fat forms; fetal movements become apparent.
- Eight Lunar Months: High likelihood of survival for preterm infants with proper care; responds to external stimuli.
- Nine Lunar Months: Fetus reaches a rounded body shape; develops skin and fat layers.
Key Points About Fetal Viability
- Infants born at 32 weeks have a high survival rate.
- Fetal heartbeat detectable; sex identifiable by 14 weeks through ultrasound.
- The L/S (lecithin/sphingomyelin) ratio supports lung maturity.
Medical Interventions
- Management of Infections (e.g., genital herpes): C-section may be recommended for women with lesions during labor.
- Syphilis Treatment: Benzathine penicillin effective in early pregnancy; untreated cases lead to severe fetal complications.
Understanding these key concepts, risks, and developmental milestones is crucial for maternal and child health nursing.
