Which factors would change during pregnancy if the hormone progesterone were withdrawn or reduced?
Insulin resistance would be increased.
Sweat and sebaceous glands would increase production.
Pyrosis would increase in frequency.
Peristalsis and uterine contractility would increase.
The Correct Answer is D
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If progesterone were reduced or withdrawn, the uterus would contract more and peristalsis would increase, leading to possible preterm labor and digestive problems.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 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
95 to 105 mmHg.
This is the normal range for PaO2 in pregnancy according to several sources.
PaO2 is the partial pressure of oxygen in arterial blood and reflects the oxygenation of the blood.
It is influenced by factors such as ventilation, perfusion, diffusion, and hemoglobin affinity.
Choice A is wrong because 27 to 32 mmHg is too low for PaO2 and would indicate severe hypoxemia or low oxygen levels in the blood.
Choice C is wrong because 500 to 700 mL is a measure of tidal volume, not PaO.
Tidal volume is the amount of air that moves in and out of the lungs with each breath.
Choice D is wrong because 7 to 10 L/min is a measure of oxygen flow rate, not PaO.
Oxygen flow rate is the amount of oxygen delivered to a patient through a device such as a nasal cannula or a mask.
