Question

After the 10th week of pregnancy, cardiac output can increase 1.0-1.5 L/min because of the increase in plasma volume and decrease in vascular resistance of the uterus and placenta.

A.True
B.False

Answer 1

The statement that after the 10th week of pregnancy, cardiac output can increase 1.0-1.5 L/min due to the increase in plasma volume and decrease in vascular resistance of the uterus and placenta is true. During pregnancy, there are significant changes in the maternal circulatory system.

So, the correct answer is A. true.

Step-by-step explanation:

Cardiac output increases during pregnancy due to an increase in plasma volume and a decrease in vascular resistance in the uterus and placenta. The increase in blood volume by approximately 30 percent or about 1-2 liters by childbirth, helps accommodate the needs of the fetus for nourishment and waste removal. Concurrently, cardiac output increases to deliver the greater blood volume throughout the body. The vasculature of the uterus and placent.
So, the correct answer is A. true.
