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 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If progesterone were reduced or withdrawn, the uterus would contract more and peristalsis would increase, leading to possible preterm labor and digestive problems.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 D
Explanation
Prolactin is a hormone that is responsible for inhibiting ovulation and stimulating milk production during pregnancy.
It is produced by the anterior pituitary gland and increases throughout pregnancy.
Choice A is wrong because hCG (human chorionic gonadotropin) is a hormone that is produced by the placenta and maintains the corpus luteum, which secretes progesterone and estrogen.
hCG does not inhibit ovulation or stimulate milk production.
Choice B is wrong because progesterone is a hormone that is produced by the corpus luteum and the placenta and supports the endometrium, prevents uterine contractions, and prepares the breasts for lactation.
Progesterone does not inhibit ovulation or stimulate milk production.
Choice C is wrong because estrogen is a hormone that is produced by the corpus luteum and the placenta and stimulates uterine growth, blood flow, and breast duct development.
Estrogen does not inhibit ovulation or stimulate milk production.
