Quiz zum Vortrag
Which of the following physiologic changes occur in the cardiovascular system during pregnancy?
- Cardiac output increases due to multiple factors, including an increase in heart rate.
- Cardiac output increases due to multiple factors, including an increase in mean arterial pressure.
- Cardiac output increases due to multiple factors, including a decrease in heart rate and an increase in systemic vascular resistance.
- Cardiac output decreases due to multiple factors, including a decrease in blood pressure.
- Cardiac output remains the same due to an increase in heart rate and a decrease in mean arterial pressure.
Which of the following changes occurs in the cardiovascular system during pregnancy?
- The heart is displaced leftward and upward.
- The systemic vascular resistance increases.
- The mean arterial pressure increases.
- The heart rate decreases.
- The cardiac output decreases.
Which of the following hematological changes occur during pregnancy?
- Maternal blood volume increases by 40–45% compared with non-maternal blood volume.
- Maternal iron requirements decrease due to an increase in erythropoiesis.
- The maternal immune system strengthens to protect the fetus from pathogens.
- Maternal plasma volume decreases relative to whole blood volume.
- Maternal hypocoagulable state increases the risk of abnormal bleeding during pregnancy.
A 28-year-old female is post-operative day one after an emergency C-section of her term infant. She had no other complications during pregnancy and has no other past medical problems. Which of the following factors puts her at an increased risk of developing a deep vein thrombosis?
- Increased hypercoagulability during pregnancy and immediate post-partum state and post-operative status
- Increased hypercoagulability due to post-operative status only
- Increased plasma volume during pregnancy
- Increased cardiac output during labor and delivery
- Physiologic anemia
Which of the following changes occur in the maternal respiratory physiology during pregnancy?
- Decreased expiratory residual volume
- Decreased minute ventilation
- Increased total lung capacity
- Increased residual volume
- Decreased tidal volume
Which of the following changes occurs in the pulmonary system during pregnancy?
- The diaphragm rises by 4 cm, decreasing functional residual capacity.
- The diaphragm drops by 4 cm, increasing minute ventilation.
- The diaphragm drops by 4 cm, increasing tidal volume.
- The diaphragm rises by 4 cm, increasing residual volume.
- The diaphragm rises by 4 cm, decreasing total lung capacity.

Dr. Gillispie has a great presence and attitude that regardless my very low interest in obstetrics I get hooked to her lessons. I am glad I found her videos because Obstetrics is one of my weak areas.
The presentation was brief and simplified thanks too much and I hope like these lectures in future
very simple to the point and explain many thing was difficult to me
This lecture was engaging, clearly explained and time efficient. It's really easy to memorize key information using this short video. Thank you!
