Correct Answer: B

Rationale: In this scenario, the most appropriate action for the nurse to take is to obtain a specimen of urethral drainage for culture. This procedure can help diagnose the cause of burning on urination, which could be indicative of a sexually transmitted infection. Option A, observing for a chancroid-like lesion, may not be the most immediate or relevant action in this case. Option C, assessing for perineal itching, erythema, and excoriation, is important but obtaining a culture specimen would provide more specific diagnostic information. Option D, identifying all sexual partners, is relevant for contact tracing but obtaining a culture specimen is the priority to determine the current infection status.

Correct Answer: C

Rationale: Continuing to monitor the fluid output is the appropriate action in this situation. Monitoring the fluid output helps the nurse assess the client's ongoing response to the procedure and detect any sudden changes, such as increased or decreased drainage rate, which could indicate complications. Palpating for abdominal distention, sending fluid to the lab for analysis, or clamping the drainage tube are not necessary actions at this point, as the priority is to monitor the client's condition post-procedure.

Correct Answer: B

Rationale: The correct intervention the nurse should implement first is to determine the client's blood pressure. Assessing the blood pressure is crucial in this situation to rule out physiological causes like hypotension leading to the client's disorientation. Administering a sedative (Choice A) without understanding the underlying cause may worsen the situation. Applying soft restraints (Choice C) should not be the initial action and can be considered later if necessary. Calling for assistance (Choice D) may be needed eventually, but assessing the client's blood pressure takes precedence to address the immediate concern.

Correct Answer: D

Rationale: Thrombolytic therapy increases the risk of bleeding, not infection, fluid volume deficit, or impaired skin integrity. The most significant concern with thrombolytic therapy is the potential for bleeding complications, which can lead to various injuries. Therefore, 'Risk for injury related to effects of thrombolysis' is the most appropriate nursing diagnosis in this scenario. Choices A, B, and C are incorrect as they do not directly correlate with the primary risk associated with thrombolytic therapy.

Correct Answer: A

Rationale: The correct answer is A: 'Report any signs of a sore throat or fever immediately.' Phenytoin can cause blood dyscrasias, which can manifest as a sore throat or fever. These symptoms could indicate a serious side effect that requires immediate medical attention. Choice B is incorrect because phenytoin should not be taken with antacids as they can decrease its absorption. Choice C is incorrect because discontinuing phenytoin abruptly can lead to rebound seizures; drowsiness is a common side effect that may improve with time. Choice D is incorrect because adjusting the dosage of phenytoin should only be done under healthcare provider supervision, not based on experiencing an aura.
