    Study Notes

    Ovulation

    • Ovulation happens around day 14 in a 28-day cycle
    • It lasts about 24 hours
    • Symptoms:
      • Slight rise in basal body temperature
      • Thicker discharge with the texture of egg whites

    Luteal Phase

    • The follicle transforms into the corpus luteum after releasing its egg
    • The corpus luteum releases hormones, mainly progesterone and some estrogen
    • The rise in hormones keeps the uterine lining thick and ready for implantation
    • If pregnant, the body produces human chorionic gonadotropin (HCG), maintaining the corpus luteum and uterine lining
    • If not pregnant, the corpus luteum shrinks, leading to decreased estrogen and progesterone, initiating menstruation

    Twins

    • Two babies born at the same time
    • Can be identical (monozygotic) or fraternal (dizygotic)

    Identical Twins

    • Formed when a single fertilized egg splits into two embryos
    • Genetically identical
    • Always the same sex (boy-boy or girl-girl)
    • Relatively rare, occurring in about 1 in 250 births
    • Higher risk of certain genetic disorders

    Fraternal Twins

    • Formed when two separate eggs are fertilized by two separate sperm
    • Genetically different, like any other siblings
    • Can be the same sex or different sexes

    Challenges of Raising Twins

    • Double the work
    • Lack of sleep
    • Financial strain
    • Social isolation

    Fertilization

    • Sperm cells travel through the vagina, cervix, and uterus to reach the egg in the Fallopian tube
    • One sperm cell penetrates the egg and fertilizes it
    • The fertilized egg (zygote) divides and develops into a blastocyst
    • The blastocyst implants in the uterine wall and develops into an embryo
    • Genetic material from sperm and egg combine to form a single diploid nucleus with 46 chromosomes
    • The zygote undergoes mitosis, dividing into two identical daughter cells

    2nd Trimester

    • Weeks 13-28
    • Fetal movements
    • Skin darkening
    • Swelling in extremities
    • Breast/belly growth
    • Braxton-Hicks

    3rd Trimester

    • Weeks 29-40
    • Dyspnea (hard breathing)
    • Difficulty sleeping
    • Colostrum leaks
    • Lochia (blood: body fluid)
    • Fatigue
    • Breast soreness/leaking
    • Postpartum depression risk

    False Labor Symptoms

    • Discomfort over the lower abdomen and groin areas, not associated with dilation
    • Typically shorter in duration
    • Less intense
    • Relieved by sedatives or ambulation

    True Labor Symptoms

    • Discomfort over the fundus with radiation to the back and low abdomen
    • Associated with effacement and dilation
    • Increasingly intense and frequent
    • Regular and effective

    Medical Intervention for Ectopic Pregnancy

    • Methotrexate: Injections that stop the growth of ectopic tissue allowing the body to reabsorb it, most effective when diagnosed early
    • Laparoscopy: A minimally invasive procedure using small incisions and a laparoscope to remove the ectopic tissue or the affected fallopian tube
    • Laparotomy: A more invasive surgery with a larger incision, used for severe internal bleeding, significant damage, or when laparoscopy isn’t feasible
    • Expectant Management: Watchful waiting by monitoring with blood tests and ultrasounds for small, asymptomatic ectopic pregnancies

    Psychological Changes of Pregnancy

    • The woman’s attitude toward pregnancy depends on the environment she’s raised in
    • Social influences: Pregnancy is not an illness, the family is included
    • Increased use of birthing centers
    • Demedicalize childbirth

    Factors Affecting Labor (5 P’s)

    • Passenger (the fetus): The fetus’s relationship to the passageway is the major factor in the birthing process

    Complete Blood Count (CBC)

    • Measures the number of red blood cells, white blood cells, and platelets in the blood

    Hemoglobin Levels

    • Measures the amount of hemoglobin in the blood

    Serum Iron Levels

    • Measures the amount of iron in the blood

    Ferritin Levels

    • Measures the amount of iron stored in the body

    Iron Deficiency Anemia Treatment

    • Address underlying cause and replenish iron stores
    • Oral iron supplements
    • Intravenous (IV) iron
    • Consuming vitamin C-rich foods

    Antepartum Hemorrhage and Placenta Previa

    • Associated with IUGR

    Intrauterine Growth Retardation (IUGR)

    • Structural abnormalities in the fetus can impede growth
    • Twins or higher-order multiples can experience restricted growth due to competition for resources
    • Uterine abnormalities like fibroids can impact fetal growth
    • IUGR Symptoms:
      • Small for Gestational Age (SGA)
      • Reduced Fetal Movements
      • Low Amniotic Fluid
      • Abnormal Doppler Ultrasound Findings

    IUGR Medical Intervention

    • Monitoring and diagnosis through ultrasounds and Doppler studies

    Gestational Diabetes

    • Can increase the risk of having a cesarean section because the baby may be large
    • A cesarean section is a major surgery

    Pregnancy Food Recommendations

    • Choose high-protein or carbohydrate foods like crackers, bread, pretzels, nuts, and low-fat yogurt
    • Avoid spicy, greasy, or acidic foods
    • Drink cold, clear fluids like sports drinks or ginger ale, and avoid coffee
    • Drink between meals instead of with them
    • Suck on popsicles or ginger-flavored lollipops
    • Brush your teeth right after eating
    • Avoid lying down right after eating
    • Take your vitamins at bedtime with a snack, not in the morning
    • Stay away from things that upset your stomach like stuffy rooms, strong smells, hot places, or loud noises
    • Have someone else prepare your meals
    • Wear acupressure bands on your wrists to help with nausea

    Hyperemesis Gravidarum Treatment

    • Treatment focuses on managing symptoms and preventing dehydration
    • Intravenous fluids
    • Anti-nausea medications
    • Diet modifications
    • Rest and relaxation

    Family Planning Objectives (WHO)

    • Avoid unwanted birth
    • Bring about wanted birth
    • Produce a change in the number of children born
    • Regulate the intervals between pregnancies
    • Control the time at which birth occurs

    Scope of Family Planning

    • Proper spacing and limitation of births
    • Advice on sterility
    • Education for parenthood
    • Sex education
    • Screening for pathological conditions related to the reproductive system
    • Genetic counseling

    Advantages of Natural Family Planning

    • Free from side effects of artificial substances
