Question

Minute ventilation increases primarily due to an increase in tidal volume. Hypocapnia (30 mm Hg) is common in late pregnancy.

A. True
B. False

Answer 1

Minute ventilation increases primarily due to an increase in tidal volume. Hypocapnia (30 mm Hg) is not common in late pregnancy. False.

Step-by-step explanation:

The statement is false. Minute ventilation increases primarily due to an increase in tidal volume, which is the amount of air that is inhaled or exhaled during a normal respiratory cycle. Hypocapnia refers to a decreased level of carbon dioxide in the blood, typically below 35 mm Hg. It does not occur commonly in late pregnancy because minute ventilation increases to compensate for the increased oxygen demands of the fetus and the mother's metabolic rate. Therefore, the level of carbon dioxide in the blood during late pregnancy is unlikely to be as low as 30 mm Hg.
