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 A
Explanation
Choice A rationale
Jitteriness indicates hypoglycemia in newborns as glucose is critical for neonatal brain function. Blood glucose less than 45 mg/dL supports this diagnosis, requiring prompt intervention to avoid neurological harm.
Choice B rationale
Hypertonia typically suggests central nervous system dysfunction but is not a hypoglycemia indicator. Normal newborn muscle tone ranges are neither hypertonic nor hypotonic in non-pathological states.
Choice C rationale
Acrocyanosis is common in newborns due to immature circulatory systems. It is not indicative of hypoglycemia and resolves as peripheral circulation improves.
Choice D rationale
Generalized petechiae suggest coagulation disorders or sepsis, not hypoglycemia. Petechiae warrant investigation of clotting abnormalities or infections, rather than focusing on glucose regulation.
Correct Answer is ["A","B"]
Explanation
Choice A rationale
Continuous monitoring of fetal heart rate provides early detection of distress in placenta previa cases, ensuring timely intervention to prevent complications such as fetal hypoxia or preterm birth.
Choice B rationale
Betamethasone accelerates fetal lung maturity, reducing the risk of respiratory distress syndrome if preterm delivery occurs, which is crucial in placenta previa cases at 35 weeks of gestation.
Choice C rationale
Cervical checks in placenta previa cases increase the risk of bleeding and further complications due to disruption of placental attachment, contraindicating frequent dilation assessments.
Choice D rationale
Misoprostol is contraindicated in placenta previa due to its potential to induce uterine contractions, which can worsen bleeding and lead to placental separation or fetal harm.
