Correct Answer: B

Rationale: When mothers smoke during pregnancy, it is associated with intrauterine growth restriction, which leads to lower birth weights in infants. Maternal smoking can restrict the flow of oxygen and nutrients to the fetus, affecting its growth and development. This can result in babies being born with lower birth weights, which can have various health implications for the newborn. Choices A, C, and D are incorrect as smoking during pregnancy is primarily linked to intrauterine growth restriction and lower birth weights in infants, rather than lower Apgar scores, respiratory distress, or a higher rate of congenital anomalies.

Correct Answer: A

Rationale: The administration of Betamethasone (Celestone) is crucial in cases of preterm labor to promote fetal lung maturation and reduce the risk of respiratory distress syndrome in the newborn. Betamethasone helps enhance the production of surfactant in the fetal lungs, improving their functionality and decreasing the likelihood of respiratory complications upon birth. Butorphanol is an analgesic and not indicated for preventing respiratory syndrome in preterm infants. Ampicillin is an antibiotic used for infection prevention and treatment, not for fetal lung maturation. Terbutaline is a tocolytic agent used to inhibit contractions, but it does not have a direct effect on fetal lung maturity.

Correct Answer: A

Rationale: The best nursing intervention for a pregnant woman with hyperemesis gravidarum is to administer the prescribed IV solution. Hyperemesis gravidarum is a severe form of nausea and vomiting during pregnancy that can lead to dehydration and electrolyte imbalances. Administering IV fluids helps in managing dehydration, replenishing electrolytes, and providing the necessary hydration for both the mother and the fetus. Giving oral rehydration solution (Choice B) may not be sufficient for severe cases of hyperemesis gravidarum where IV fluids are required. Encouraging small, frequent meals (Choice C) may not be effective as the woman may not be able to tolerate oral intake. Offering ginger tea (Choice D) is not the most appropriate intervention for hyperemesis gravidarum, as it may not provide adequate hydration or electrolyte balance needed in severe cases.

Correct Answer: A

Rationale: Complete bedrest is necessary for a pregnant client with mitral stenosis Class III to reduce the workload on the heart, lower oxygen consumption, and prevent complications associated with cardiac conditions like mitral stenosis. By remaining in bed, the client can help maintain cardiac function and promote a safer pregnancy outcome. Choice B is incorrect as it does not provide a specific reason related to the client's medical condition. Choice C is not addressing the medical necessity of bedrest for this particular client. Choice D is irrelevant and does not explain the importance of bedrest for a pregnant client with mitral stenosis Class III.

Correct Answer: D

Rationale: In the scenario presented, the client is exhibiting signs and symptoms of severe preeclampsia, including hypertension, proteinuria, facial and hand swelling, visual disturbances, and a severe headache. The medication of choice for preventing seizures in preeclampsia is magnesium sulfate. This drug helps to prevent and control seizures in clients with preeclampsia, making it the most appropriate option for this client. Clonidine hydrochloride (Choice A) is an antihypertensive medication used for managing hypertension but is not the first-line treatment for preeclampsia. Carbamazepine (Choice B) is an anticonvulsant used for seizure disorders like epilepsy and is not indicated for preeclampsia. Furosemide (Choice C) is a diuretic used to manage fluid retention but is not the drug of choice for treating preeclampsia.
