A pregnant client reports experiencing frequent urination at night.
The nurse explains that this symptom is primarily caused by:.
Increased glomerular permeability.
Decreased renal blood flow.
Increased tubular reabsorption.
Increased urinary output.
The Correct Answer is D
This is because a pregnant client may experience frequent urination at night due to increased urinary output caused by the increased blood volume and renal function during pregnancy.
This symptom is more common in the first and third trimesters.
Choice A is wrong because increased glomerular permeability does not cause nocturia, but it may cause proteinuria, which is the presence of protein in the urine.
Choice B is wrong because decreased renal blood flow does not cause nocturia, but it may cause renal ischemia, which is a condition where the kidneys do not receive enough blood supply.
Choice C is wrong because increased tubular reabsorption does not cause nocturia, but it may cause water retention and edema, which are swelling of the body tissues due to fluid accumulation.

Correct Answer is A
Explanation
The correct answer is choice A. The client reports a decrease in nausea and vomiting.
This indicates that the treatment has been effective in reducing the symptoms of hyperemesis gravidarum and improving the quality of life of the client.
Choice B is wrong because weight gain alone is not a reliable indicator of treatment effectiveness.
Weight gain may be due to fluid retention or other factors unrelated to nausea and vomiting.
Choice C is wrong because urine specific gravity of 1.035 is high and indicates dehydration, which is a complication of hyperemesis gravidarum.
The normal range of urine specific gravity is 1.005 to 1.0302.
Choice D is wrong because hematocrit of 38% is within the normal range for pregnant women (33 to 39%) and does not reflect the severity or improvement of hyperemesis gravidarum.
Correct Answer is B
Explanation
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.
