Correct Answer: B

Rationale: Smoking during pregnancy is associated with intrauterine growth restriction, leading to lower birth weights. This occurs due to the harmful effects of smoking on fetal development, which can result in reduced nutrient and oxygen supply to the fetus, impacting its overall growth and leading to lower birth weights. Choices A, C, and D are incorrect as smoking during pregnancy primarily affects fetal growth and development, leading to lower birth weights rather than lower Apgar scores, respiratory distress, or a higher rate of congenital anomalies.

Correct Answer: B

Rationale: In a child with a sickle cell crisis, the priority intervention is to initiate normal saline IV at 50 ml/hr to manage dehydration and help alleviate pain. This intervention helps improve hydration status and supports the circulation of sickled red blood cells, reducing the risk of vaso-occlusive episodes and associated pain. Obtaining a culture of any sputum or wound drainage (Choice A) may be necessary but is not the initial priority. Administering a loading dose of penicillin IM (Choice C) is important but not the first intervention. Administering the initial dose of folic acid PO (Choice D) is beneficial but does not address the immediate need for hydration in a sickle cell crisis.

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.

Correct Answer: D

Rationale: The best time for the couple to attend childbirth preparation classes is around 30 weeks gestation, which is during the third trimester. Attending classes at this time allows the couple to learn essential information and skills as labor and delivery are approaching, maximizing the benefit of the classes. Option A is too early in the second trimester, and the couple might forget important details by the time labor approaches. Option B is also early in the second trimester, and attending later allows for better preparation. Option C is still in the second trimester, and waiting until the third trimester provides more practical knowledge closer to delivery.

Correct Answer: C

Rationale: An abnormal oral glucose tolerance test result is indicative of gestational diabetes. This test is crucial in diagnosing gestational diabetes as it evaluates how well the body processes glucose after a sugary drink. Reporting abnormal results promptly allows for timely intervention and management to ensure the well-being of both the mother and the baby. The other options are not the primary tests used to diagnose gestational diabetes. Hemoglobin A1C is not recommended for diagnosing gestational diabetes as it reflects long-term glucose control. Postprandial blood glucose and fasting blood glucose tests are not as sensitive as the oral glucose tolerance test for diagnosing gestational diabetes.
