    About the Lecture

    The lecture Pregnancy Physiology: Cardiovascular, Hematologic and Respiratory System by Veronica Gillispie, MD, FACOG is from the course Antenatal Care. It contains the following chapters:

    • Physiology of Pregnancy
    • Cardiovascular System
    • Hematologic System
    • Respiratory System

    Included Quiz Questions

    1. Cardiac output increases due to multiple factors, including an increase in heart rate
    2. Cardiac output increases due to multiple factors, including an increase in mean arterial pressure.
    3. Cardiac output increases due to multiple factors, including a decrease in heart rate and an increase in systemic vascular resistance.
    4. Cardiac output decreases due to multiple factors, including a decrease in blood pressure.
    5. Cardiac output remains the same due to an increase in heart rate and a decrease in mean arterial pressure.
    1. The heart is displaced leftward and upward
    2. The systemic vascular resistance increases
    3. The mean arterial pressure increases
    4. The heart rate decreases
    5. The cardiac output decreases
    1. Maternal blood volume increases by 40-45%.
    2. Maternal iron requirements decrease due to an increase in erythropoiesis .
    3. Maternal immune system is strengthened to protect the fetus from pathogens.
    4. Maternal plasma volume decreases relative to her whole blood volume.
    5. Maternal hypocoagulable state increases risk of abnormal bleeding during pregnancy.
    1. Normal hypercoagulability during pregnancy and immediate post-partum state AND post-operative status.
    2. Post-operative status only
    3. Increased plasma volume during pregnancy
    4. Increased cardiac output during labor and delivery
    5. Physiologic anemia
    1. Decreased end reserve volume
    2. Decreased total lung capacity
    3. Increased total lung capacity
    4. Increased end reserve volume
    5. Decreased tidal volume
    1. The diaphragm rises by 4cm, decreasing functional residual capacity
    2. The diaphragm drops by 4cm, increasing minute ventilation
    3. The diaphragm drops by 4cm, increasing tidal volume
    4. The diaphragm rises by 4cm, increasing residual volume
    5. The diaphragm rises by 4cm, decreasing total lung capacity
