For each of the following potential antihypertensive medications, indicate whether it is recommended or not recommended for use in a pregnant client.
Methyldopa.
Lisinopril.
Labetalol.
Losartan.
Hydralazine.
The Correct Answer is {"A":{"answers":"A"},"B":{"answers":"B"},"C":{"answers":"A"},"D":{"answers":"B"},"E":{"answers":"A"}}
Choice A rationale
Methyldopa is a first-line antihypertensive for pregnancy-induced hypertension. It is safe, effective, and preferred due to its minimal placental transfer and limited fetal impact.
Choice B rationale
Lisinopril, an ACE inhibitor, is contraindicated in pregnancy due to teratogenic risks, including fetal renal malformations and oligohydramnios. It poses significant dangers to fetal health.
Choice C rationale
Labetalol, a combined alpha and beta-blocker, is recommended for managing hypertensive crises in pregnancy. It offers effective blood pressure control with a favorable safety profile.
Choice D rationale
Losartan, an angiotensin II receptor blocker, is not recommended in pregnancy. It risks fetal toxicity, including kidney dysfunction and growth restriction, similar to ACE inhibitors.
Choice E rationale
Hydralazine is a vasodilator safe for pregnancy. It is recommended for treating severe hypertensive emergencies, particularly in preeclampsia, due to its efficacy in reducing vascular resistance.

Correct Answer is B
Explanation
Choice A rationale
Inspecting the perineum does not address uterine atony, which is the leading cause of postpartum hemorrhage. Interventions should focus on uterine contraction to minimize bleeding.
Choice B rationale
Massaging the fundus stimulates uterine contractions, reducing uterine atony and preventing further hemorrhage. This is a first-line intervention for postpartum excessive bleeding.
Choice C rationale
Administering oxytocin enhances uterine contractions and is effective in managing hemorrhage. However, fundal massage is prioritized initially to assess uterine tone and response.
Choice D rationale
Assisting the client to void helps empty the bladder, which may improve uterine contraction. However, fundal massage is the most immediate measure to prevent further bleeding.
Correct Answer is B
Explanation
Choice A rationale
Intravenous medications are not administered for a nonstress test, which evaluates fetal heart rate response to movement using external monitoring. No pharmacological intervention is needed.
Choice B rationale
Nonstress tests typically last about 20–40 minutes, depending on fetal activity and reactivity. This duration allows sufficient time to observe fetal heart rate accelerations.
Choice C rationale
There are no dietary restrictions for a nonstress test, as the procedure involves non-invasive external monitoring and does not affect digestion or metabolic processes.
Choice D rationale
A nonstress test does not assess fetal lung maturity but evaluates fetal heart rate accelerations in response to fetal movement to ensure fetal well-being.
