A nurse is explaining the musculoskeletal changes during pregnancy to a group of expectant mothers.
Which change alters the center of gravity and posture of the body?
Increased joint laxity.
Increased spinal curvature.
Increased muscle strain.
Decreased muscle strength.
The Correct Answer is B
This change alters the center of gravity and posture of the body because the uterus expands and shifts higher as the fetus grows during pregnancy.
This causes an increased strain on the muscles and ligaments supporting the vertebral column and leads to lower back pain.
Choice A is wrong because increased joint laxity does not alter the center of gravity and posture of the body.
It is caused by hormonal changes that loosen the ligaments throughout the body, resulting in decreased stability of the joints.
Choice C is wrong because increased muscle strain does not alter the center of gravity and posture of the body.
It is a consequence of the shift in the center of gravity and the weight gain during pregnancy, which put more pressure on the back muscles.
Choice D is wrong because decreased muscle strength does not alter the center of gravity and posture of the body.
It is not a common musculoskeletal change during pregnancy, although some women may experience fatigue or weakness due to hormonal changes or anemia.

Correct Answer is D
Explanation
Peristalsis and uterine contractility would increase.
This is because progesterone is a hormone that relaxes the smooth muscles of the uterus and the gastrointestinal tract during pregnancy.
If progesterone were reduced or withdrawn, the uterus would contract more and peristalsis would increase, leading to possible preterm labor and digestive problems.
Choice A is wrong because insulin resistance would be decreased, not increased, by lower progesterone levels.
Progesterone increases insulin resistance during pregnancy to ensure adequate glucose supply for the fetus.
Choice B is wrong because sweat and sebaceous glands would decrease production, not increase, by lower progesterone levels.
Progesterone stimulates the activity of these glands during pregnancy to regulate body temperature and protect the skin from infections.
Choice C is wrong because pyrosis (heartburn) would decrease in frequency, not increase, by lower progesterone levels.
Progesterone relaxes the lower esophageal sphincter during pregnancy, allowing gastric acid to reflux into the esophagus and cause pyrosis.
Correct Answer is B
Explanation
Back pain is a common symptom experienced due to increased muscle strain during pregnancy.
As the uterus grows and the center of gravity shifts, there is more pressure on the lower back muscles and ligaments.
This can cause pain, difficulty with balance, and reduced activity.
Choice A is wrong because leg cramps are not caused by muscle strain, but by other factors such as dehydration, electrolyte imbalance, or compression of blood vessels.
Choice C is wrong because pelvic pain is not a typical symptom of musculoskeletal changes during pregnancy.
Pelvic pain can be caused by other conditions such as urinary tract infection, preterm labor, or pelvic girdle pain.
Choice D is wrong because carpal tunnel syndrome is not a result of muscle strain, but of fluid retention and swelling that compresses the median nerve in the wrist.
This can cause numbness, tingling, or pain in the hand and fingers.
