Question 1

Increased lumbar lordosis during pregnancy results primarily from:

Accepted Answer

The anterior shift of the center of gravity as the uterus enlarges

Answer

As the pregnant abdomen grows anteriorly, the center of gravity shifts forward, prompting compensatory increased lumbar lordosis to maintain balance.

Question 2

Which term describes the common condition where the pregnant uterus rotates slightly to the right?

Accepted Answer

Dextrorotation

Answer

Dextrorotation (rightward rotation) of the uterus is common because the rectosigmoid colon on the left side displaces the uterus toward the right.

Question 3

Carpal tunnel syndrome during pregnancy is largely caused by:

Accepted Answer

Fluid retention causing edema that compresses the median nerve at the wrist

Answer

Pregnancy-associated edema increases fluid in the carpal tunnel, compressing the median nerve and producing tingling, numbness, and weakness in the hand.

Question 4

The hormone progesterone contributes to constipation during pregnancy primarily by:

Accepted Answer

Reducing intestinal smooth muscle motility

Answer

Progesterone relaxes smooth muscle throughout the body, including the intestines, slowing peristalsis and causing the constipation common in pregnancy.

Question 5

During pregnancy the cardiac output increases by approximately:

Accepted Answer

30–50%

Answer

Cardiac output rises 30–50% above pre-pregnancy baseline, achieved through increased heart rate and stroke volume to meet the metabolic demands of the mother and fetus.
