Correct Answer: C

Rationale: The correct action to include in caring for a client scheduled for a lumbar puncture is to instruct the client to increase oral fluid intake after the procedure. Increasing oral fluid intake helps replace cerebrospinal fluid lost during the lumbar puncture and reduces the risk of headaches. Restricting fluid intake (Choice A) is not recommended as it can lead to dehydration. Applying cold compresses (Choice B) is not necessary after a lumbar puncture. Keeping the client in a prone position for 12 hours (Choice D) is not required after a lumbar puncture and can cause discomfort and complications.

Correct Answer: C

Rationale: The correct information the nurse should include is that menopausal hormone therapy helps prevent osteoporotic fractures by maintaining bone density. Option A is incorrect as hormone therapy should be taken consistently at the same time each day for optimal effectiveness. Option B is incorrect as menopausal hormone therapy is not primarily aimed at preventing cerebral hemorrhage. Option D is incorrect because taking an extra dose is not recommended if a dose is missed; instead, the missed dose should be taken as soon as remembered, unless it is close to the time for the next dose.

Correct Answer: C

Rationale: Administering oxygen by face mask is the priority intervention when late decelerations are observed in the fetal heart rate. Late decelerations indicate uteroplacental insufficiency, and administering oxygen helps to improve fetal oxygenation. Repositioning the client may also be necessary to relieve pressure on the umbilical cord, but providing oxygen takes precedence to enhance fetal oxygenation. Decreasing IV fluids may not directly address the underlying issue leading to late decelerations. Documenting the findings is important but should not be the first action taken when managing late decelerations.

Correct Answer: C

Rationale: Corrected Rationale: Dantrolene is the medication of choice to treat malignant hyperthermia, a life-threatening reaction to general anesthesia. It works by inhibiting the release of calcium ions in skeletal muscle cells, preventing muscle contracture and hypermetabolism. Acetaminophen (Choice A) and ibuprofen (Choice B) are not indicated for treating malignant hyperthermia. Diazepam (Choice D) may be used to control muscle spasms but is not the first-line treatment for malignant hyperthermia.

Correct Answer: A

Rationale: The correct answer is A. Common side effects of opioid analgesics include drowsiness and dizziness. These side effects can impair a person's ability to operate machinery or drive safely. To manage these side effects, it is essential to advise patients to avoid activities that require alertness until they know how the medication affects them. Choices B, C, and D are incorrect because respiratory depression, constipation, and nausea are also common side effects of opioids, but they are not the primary side effects being asked for in this question.
