Correct Answer: C

Rationale: The most appropriate question for the nurse to ask is whether the client has any active herpes lesions. This is crucial because the presence of active lesions can necessitate a cesarean section to prevent transmission of the virus to the newborn. Asking about membrane rupture (choice A) is important but not directly related to the client's herpes simplex virus 2 status. Inquiring about the frequency of contractions (choice B) is relevant for assessing labor progression but does not address the immediate concern of herpes transmission. Asking about being positive for beta strep (choice D) is important for determining the need for prophylactic antibiotics during labor, but it is not directly related to the client's herpes simplex virus 2 status.

Correct Answer: B

Rationale: Fullness in the throat after a thyroidectomy could indicate bleeding or a hematoma, which can compress the airway, so hemorrhage is the priority concern. Hypocalcemia typically presents with symptoms like tingling around the mouth or in the extremities, muscle cramps, or seizures, not fullness in the throat. Hypoxia would manifest with symptoms like shortness of breath, confusion, or cyanosis, rather than a feeling of fullness in the throat. Hypothyroidism symptoms include fatigue, weight gain, and cold intolerance, but it does not typically cause acute fullness in the throat postoperatively.

Correct Answer: A

Rationale: The correct answer is A: "Hypnosis promotes increased control of pain perception during labor." Hypnosis can be effectively utilized during labor to help individuals enhance their control over how they perceive pain. Choice B is incorrect because hypnosis does not primarily use therapeutic touch to reduce anxiety. Choice C is incorrect as hypnosis is not primarily focused on biofeedback as a relaxation technique. Choice D is incorrect because hypnosis does not provide direct instructions to minimize pain but rather helps individuals gain control over their pain perception.

Correct Answer: A

Rationale: A paradoxical pulse is a sign of cardiac tamponade, a life-threatening complication of pericarditis that requires immediate intervention. It results from decreased cardiac output due to increased pressure in the pericardial sac. Reporting this finding promptly allows for timely treatment to prevent further deterioration. Dependent edema and substernal chest pain are common in pericarditis but are not as urgent as a paradoxical pulse. A pericardial friction rub is a classic finding in pericarditis and indicates inflammation but is not as critical as a paradoxical pulse.

Correct Answer: B

Rationale: The correct answer is B. A urine output of 20 mL/hour is a sign of magnesium toxicity because decreased urine output can lead to accumulation of magnesium. Choices A, C, and D are not indicators of magnesium toxicity. Elevated blood glucose, high systolic blood pressure, and normal BUN levels do not specifically point towards magnesium toxicity.
