Correct Answer: B

Rationale: Corrected Question: When caring for a client receiving nifedipine for prevention of preterm labor, the nurse should monitor the client for which of the following manifestations? Rationale: Nifedipine, a calcium channel blocker, causes vasodilation, potentially leading to a decrease in blood pressure and side effects such as dizziness. Monitoring for dizziness is essential to ensure the client's safety and well-being during treatment. Choices A, C, and D are incorrect as they are not typically associated with nifedipine use for preventing preterm labor. Blood-tinged sputum may indicate other conditions like pulmonary issues, pallor could suggest anemia or circulatory problems, and somnolence is not a common side effect of nifedipine.

Correct Answer: A

Rationale: Vaginal bleeding during pregnancy is a concerning sign that could indicate serious complications like miscarriage or placental issues. Prompt reporting to the healthcare provider is crucial for timely evaluation and management to ensure the best outcomes for both the mother and the baby. Swelling of the ankles (choice B), heartburn after eating (choice C), and lightheadedness when lying on the back (choice D) are common discomforts during pregnancy but are not typically associated with serious complications that require immediate attention.

Correct Answer: C

Rationale: Maternal hypotension during pregnancy is often caused by the weight of the uterus pressing on the vena cava when the client is lying on her back, which reduces blood flow to the heart. This compression can lead to a decrease in blood pressure and subsequent symptoms of hypotension. Choice A is incorrect because an increase in blood volume typically leads to increased blood pressure rather than hypotension. Choice B is incorrect as pressure from the uterus on the diaphragm is not a common cause of maternal hypotension. Choice D is incorrect because increased cardiac output would not directly cause maternal hypotension.

Correct Answer: A

Rationale: Ceftriaxone is the preferred medication to treat gonorrhea, a bacterial infection. It is essential to promptly treat gonorrhea to prevent complications such as pelvic inflammatory disease, infertility, and the spread of the infection to others. Fluconazole is used for fungal infections, Metronidazole treats certain bacterial and parasitic infections, and Zidovudine is an antiretroviral medication used in HIV treatment; none of these are appropriate for gonorrhea.

Correct Answer: D

Rationale: The correct answer is D: Neural tube defects. Folic acid deficiency during pregnancy can lead to neural tube defects in the fetus, affecting the brain, spine, or spinal cord development. Iron deficiency anemia (choice A) is not directly related to folic acid deficiency. Poor bone formation (choice B) is more associated with calcium and vitamin D deficiencies. Macrosomic fetus (choice C) refers to a baby with excessive birth weight and is not a typical outcome of folic acid deficiency in pregnancy. Therefore, it is crucial for individuals of childbearing age to take recommended folic acid supplements to prevent neural tube defects.
