A nurse is caring for a client who is at 12 weeks of gestation and has hyperemesis gravidarum. Which of the following manifestations should the nurse expect?
Decreased BP.
WBC count 15,000/mm³ (5,000 to 15,000/mm³).
Pruritus.
Hemoglobin 18 g/dL (11 to 16 g/dL). .
The Correct Answer is A
Choice A rationale
"Decreased BP.”. This is correct because hyperemesis gravidarum can lead to dehydration, which in turn can cause hypotension (decreased blood pressure).
Choice B rationale
"WBC count 15,000/mm³ (5,000 to 15,000/mm³).”. This is incorrect because while WBC count can be elevated due to stress or infection, it is not a primary manifestation of hyperemesis gravidarum.
Choice C rationale
"Pruritus.”. This is incorrect because pruritus is not commonly associated with hyperemesis gravidarum. It is more likely related to other conditions like cholestasis of pregnancy.
Choice D rationale
"Hemoglobin 18 g/dL (11 to 16 g/dL).”. This is incorrect because an elevated hemoglobin level is not a direct manifestation of hyperemesis gravidarum, although dehydration can potentially concentrate blood components and slightly elevate hemoglobin.

Correct Answer is A
Explanation
Choice A rationale
Amniocentesis is used to detect fetal genetic abnormalities, such as Down syndrome, by analyzing the amniotic fluid for genetic markers.
Choice B rationale
An empty bladder is required for the test only in late pregnancy to prevent bladder injury; however, in early pregnancy, a full bladder may be required to better visualize the uterus and amniotic fluid.
Choice C rationale
An x-ray is not typically used during the needle placement for amniocentesis. Ultrasound is the preferred method to guide the needle to avoid harm to the fetus and mother.
Choice D rationale
The test does not determine the volume of amniotic fluid; it is used primarily for genetic analysis, assessing fetal lung maturity, and diagnosing certain fetal infections.
Correct Answer is B
Explanation
Choice A rationale
Increasing the frequency of feedings from the affected nipple may aggravate nipple soreness, as it doesn't allow the area to recover and heal properly between feedings.
Choice B rationale
Exposing the affected nipple to the air between feedings can help it to dry and heal, reducing soreness. Air exposure can help prevent bacterial growth and keep the nipple area healthy.
Choice C rationale
Applying vitamin E oil to the affected nipple before each feeding is not recommended as it can make the nipple slippery, affecting the baby's latch, and it might not be safe if ingested by the baby.
Choice D rationale
Washing the affected nipple with soap and water before each feeding can strip the natural oils from the skin, leading to further dryness and irritation, which can increase soreness.
