Study Notes
Sexual Response Cycle
- Excitement: Rapid erection occurs in men; women experience clitoral enlargement and vaginal lubrication.
- Plateau: Cowper’s gland secretes fluid, penis continues to enlarge; uterus elevates and cervix rises in women.
- Orgasm: Characterized by expulsive contraction of the urethra and ejaculation in men; women experience orgasmic platform contractions.
- Resolution: Return to pre-arousal state for both genders.
Menstrual Flow Characteristics
- Menarche: Average onset is between 11-13 years, with a range of 9-17 years.
- Cycle Interval: Average cycle is 28 days; cycles can vary from 23-25 days.
- Flow Duration: Average menstrual flow lasts 2-7 days; a range of 1-9 days is not abnormal.
- Flow Amount: Average blood loss is 30-80ml per period; saturating a pad/tampon within an hour indicates heavy bleeding.
- Flow Color: Typically dark red due to a mixture of blood, mucus, and endometrial cells.
- Odor: Resembles the scent of marigolds.
Menstruation Education
- Focus on: Exercise, sexual relations, daily activities, pain relief, nutrition, and rest.
Key Pregnancy Terms
- Primipara: A woman who has completed one pregnancy to viability.
- Nulligravida: A woman who has never been pregnant.
- Parity: Number of past pregnancies that reached viability.
- Term: Pregnancy duration from 38 to 42 weeks.
- FHR: Fetal heart rate as an indicator of fetal well-being.
Fetal Development
- All oocytes are present in ovaries at birth.
- External genital development occurs around week 12; influenced by testosterone in males and absence in females.
- Puberty: Triggered by gonadotropin-releasing hormone (GnRH); leads to the release of follicle-stimulating hormone (FSH) and luteinizing hormone (LH) promoting secondary sex characteristics.
- Early onset of dramatic reproductive maturation in girls (9-12 years).
Hormonal Roles
- Androgens: Promote muscle development and secondary male characteristics; produced in males and females.
- Estrogens: Initiate female reproductive organ development and secondary sex characteristics; include estrone, estradiol, and estriol.
Secondary Sex Characteristics During Puberty
- Girls: Growth spurts, pelvic widening, breast growth, pubic hair, menstruation onset, axillary hair development, vaginal secretions.
- Boys: Weight increase, testicular growth, facial hair, voice changes, penile growth, height increase.
Fetal Growth Stages
-
Conceptus stages from ovum to fetus:
- Ovum: From ovulation to fertilization.
- Zygote: From fertilization to implantation.
- Embryo: From implantation to 5-8 weeks.
- Fetus: From 5-8 weeks to term.
Fetal Circulation Structures
- Placenta: Facilitates gas exchange.
- Umbilical Arteries: Carry deoxygenated blood from the fetus to the placenta.
- Umbilical Vein: Delivers oxygenated blood to the fetus.
- Foramen Ovale: Shunts blood from the right to left atrium.
- Ductus Venosus: Bypasses the liver, connecting umbilical vein to inferior vena cava.
- Ductus Arteriosus: Redirects blood from the pulmonary artery to the aorta.
Signs and Symptoms of Pregnancy
- Presumptive Symptoms: Subjective signs like missed periods.
- Probable Signs: Objective evidence like positive pregnancy tests.
- Positive Signs: Confirmatory signs such as fetal heartbeat.
Maternal Physiology During Pregnancy
- Uterus: Enlarges significantly by 20 weeks.
- Cervix: Softens and exhibits cyanosis.
- Ovaries: Cease ovulation.
- Breast Changes: Tenderness, enlargement, and colostrum production.
- Weight Gain: Average of 11-13 kg during pregnancy consisting of fetus, placenta, and increased fluid volume.
Common Discomforts During Pregnancy
- Includes: Ankle edema, backache, breast tenderness, constipation, fatigue, heartburn, nausea, urinary frequency, and varicose veins.
Prenatal Visits
- Consists of checkups to monitor health and address potential complications.
Exercise During Pregnancy
- Suggested activities: Pelvic tilts, tailor-sitting, squatting, and Kegel exercises.
Immunization Schedule
- TT1: As early as possible during pregnancy.
- TT2: At least 4 weeks later.
- TT3: At least 6 months later.
Prenatal Visit Measurements
- Includes: CBC, edema check, fetal heart tones (FHT), fundal height, weight, and vital signs.
Calculating Due Date and AOG
- Nagele's Rule: Start with the first day of the last menstrual period, subtract three months, add seven days, and then add one year to estimate the delivery date.
- AOG Calculation: Number of days since LMP divided by 7 to determine weeks of gestation.
