    Study Notes

    Fetal Development and Pregnancy Adaptations

    • Fundal height measurement during pregnancy is significant because it estimates fetal age and detects any potential fetal growth restriction.
    • Braxton Hicks contractions are characterized by irregular, mild, and short-lived contractions that are often painless and unpredictable.
    • Around 4 weeks before birth, the reproductive system adaptation that occurs is the formation of the placenta taking over the majority of estrogen production.
    • The combination of decreased peristalsis, increased venous pressure, and pressure from the uterus during pregnancy can result in constipation.
    • The primary cause of the waddle gait seen in pregnant women is the shift in the center of gravity due to the growing uterus.
    • A common integumentary system adaptation seen during pregnancy is the appearance of striae gravidarum (stretch marks) on the abdomen and breasts.
    • The respiratory system adaptation during pregnancy is the increase in tidal volume and oxygen consumption, allowing for adequate oxygenation of the fetus.
    • In the renal/urinary system, adaptation during pregnancy involves an increase in renal blood flow and glomerular filtration rate, leading to increased urine production.
    • The endocrine system adaptation that is NOT characteristic of pregnancy is a decrease in insulin production.
    • The musculoskeletal system adapts to pregnancy by increasing flexibility and relaxation of pelvic joints, preparing for childbirth.
    • The cardiovascular system adaptation characteristic of pregnancy is an increase in cardiac output, blood volume, and heart rate to meet the increased blood flow demands.
    • Braxton Hicks contractions are typically irregular, mild, and short-lived, and they often start and stop abruptly.
    • The primary purpose of measuring fundal height during pregnancy is to monitor fetal growth and detect any potential complications.
    • A potential complication associated with Braxton Hicks contractions is preterm labor.
    • Cardiovascular system adaptations in pregnancy primarily affect blood pressure by increasing cardiac output, which can lead to hypertension.
    • The gastrointestinal system adaptation that contributes to constipation is decreased peristalsis and increased venous pressure.
    • Braxton Hicks contractions are distinguished from true labor contractions by their irregularity, mildness, and short duration.
    • A potential effect of severe constipation during pregnancy is hemorrhoids.
    • The reproductive system adapts to support the increased blood flow demands during pregnancy by increasing blood flow to the uterus and placenta.
    • The cardiovascular system adapts to maintain adequate blood circulation during pregnancy by increasing cardiac output and blood volume.
    • Gastrointestinal system adaptations in pregnancy are characterized by increased nutrient absorption and storage to support fetal growth.
    • Respiratory system adaptations during pregnancy primarily affect lung function by increasing oxygen consumption and tidal volume.
    • The main characteristic of Braxton Hicks contractions is their irregular, mild, and short-lived nature.
    • Around 4 weeks before birth, the reproductive system adaptation that occurs is the formation of the placenta taking over the majority of estrogen production.
    • A common gastrointestinal system adaptation during pregnancy is constipation due to decreased peristalsis and increased venous pressure.
    • The cardiovascular system adaptation that occurs during pregnancy is an increase in cardiac output, blood volume, and heart rate to meet the increased blood flow demands.
    • Measuring fundal height during pregnancy is significant because it estimates fetal age and detects any potential fetal growth restriction.
    • Braxton Hicks contractions are distinguished from true labor contractions by their irregularity, mildness, and short duration.
    • A common gastrointestinal change during pregnancy is constipation due to decreased peristalsis and increased venous pressure.
    • The cardiovascular change that occurs as a result of hemodilution during pregnancy is an increase in blood volume and cardiac output.
