A nurse is caring for a pregnant client who has hyperemesis gravidarum and is receiving IV fluids and antiemetics in an acute care facility.
Which of the following outcomes indicates that treatment has been effective?
The client reports a decrease in nausea and vomiting.
The client gains 1 kg (2.2 lb) in 24 hr.
The client's urine specific gravity is 1.035
The client's hematocrit is 38%.
The Correct Answer is A
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 A
Explanation
Progesterone is responsible for maintaining the corpus luteum and stimulating fetal growth.
Progesterone also prevents miscarriage by relaxing the uterus and maintaining the endometrium.
Choice B is wrong because estrogen is not responsible for maintaining the corpus luteum or stimulating fetal growth.
Estrogen helps develop the female sexual traits and supports the growth of the uterus and placenta.
Choice C is wrong because thyroid hormones are not responsible for maintaining the corpus luteum or stimulating fetal growth.
Thyroid hormones regulate the metabolism and energy levels of the mother and the fetus.
Choice D is wrong because prolactin is not responsible for maintaining the corpus luteum or stimulating fetal growth.
Prolactin stimulates milk production in the breasts after delivery.
Correct Answer is B
Explanation
Serum creatinine and urea are waste products of protein metabolism that are normally filtered by the kidneys and excreted in urine.
In pregnancy, the glomerular filtration rate (GFR) increases by about 50%, which means more creatinine and urea are cleared from the blood.Therefore, serum creatinine and urea levels decrease in pregnancy compared to nonpregnant women.
A. Increased serum creatinine and urea levels are wrong because they indicate impaired kidney function or dehydration, which are not normal in pregnancy.
C. Unchanged serum creatinine and urea levels are wrong because they do not reflect the increased GFR in pregnancy.
D. Increased glomerular filtration rate is correct but it is not a finding regarding serum creatinine and urea levels, which are the focus of the question.
Normal ranges for serum creatinine and urea vary depending on the laboratory and the units used, but based on a nonpregnant reference interval of 45-90 μmol/l (0.51-1.02 mg/dl) for creatinine and 2.5-6.4 mmol/l (7-18 mg/dl) for urea, a serum creatinine of >77 μmol/l (0.87 mg/dl) and a blood urea of >8.5 mmol/l (24 mg/dl) should be considered outside the normal range for pregnancy.
