Correct Answer: A

Rationale: The correct answer is A: Medication compliance over the past few weeks. In a client with chronic emphysema experiencing acute symptoms, it is crucial to assess medication compliance as it directly impacts symptom control and disease management. Ensuring the client has been adherent to their prescribed medications can provide insights into potential exacerbating factors or the need for adjustments in the treatment plan. Choices B, C, and D are less critical during the initial assessment compared to medication compliance. Recent sleep patterns and rest (choice B) may be relevant but are secondary to ensuring proper medication management. While smoking history (choice C) is important in chronic lung conditions, the immediate focus should be on the current status of medication use. Activity level prior to symptom onset (choice D) is also pertinent but not as crucial as confirming medication compliance to address the acute symptoms.

Correct Answer: B

Rationale: A significant drop in blood pressure following anesthesia could indicate a serious reaction, such as hypovolemia or anesthetic-induced hypotension. This requires immediate medical attention, while other symptoms like dizziness, mild nausea, and dry mouth are more common and less critical. Dizziness could be expected due to the effects of anesthesia, mild nausea is a common side effect, and dry mouth is a known effect of anesthesia as well.

Correct Answer: C

Rationale: A negative Pap smear does not rule out ovarian cancer, which often requires more comprehensive evaluation, including imaging studies or surgery. The client should be informed that the Pap smear primarily detects cervical cancer, not ovarian cancer. Therefore, further evaluation involving imaging studies or surgery may be necessary to determine the presence of ovarian cancer. Choice A is incorrect because a Pap smear is not sufficient to detect ovarian cancer. Choice B is incorrect because surgery may be necessary for further evaluation if ovarian cancer is suspected. Choice D is incorrect because further tests are needed to confirm or rule out ovarian cancer.

Correct Answer: C

Rationale: The correct answer is C, 'Highly protein-bound.' Drugs that are highly protein-bound can displace from protein-binding sites, leading to increased free drug levels in the blood, which can result in toxicity. Monitoring the client for toxicity is crucial when administering highly protein-bound drugs. Choices A, B, and D are incorrect. A short half-life does not necessarily indicate a need for monitoring toxicity; a high therapeutic index indicates a wide safety margin between the effective dose and the toxic dose, reducing the risk of toxicity; low bioavailability refers to the fraction of the drug that reaches the systemic circulation unchanged and does not directly relate to the risk of toxicity.

Correct Answer: B

Rationale: Oliguria, or decreased urine output, after surgery can indicate tubular necrosis due to hypoperfusion, which may require intervention to restore renal function. Choice A is incorrect as oliguria is not a normal finding after surgery. Choice C is incorrect because dehydration is less likely in this context compared to tubular necrosis. Choice D is incorrect as a urine output of 25 ml/hour is not expected after splenectomy and should raise concern for renal impairment.
