Correct Answer: C

Rationale: The correct answer is C: 'Monitor for signs of yellowing skin or eyes.' Tetracycline can cause hepatotoxicity, leading to jaundice which may present as yellowing of the skin or eyes. This is a serious side effect that the nurse should emphasize to the client. Choice A is incorrect because tetracycline should generally be taken on an empty stomach, not with food or milk. Choice B is also incorrect as tetracycline can cause photosensitivity, but it is not directly related to yellowing skin or eyes. Choice D is incorrect because tetracycline can cause yellow-brown discoloration of the teeth, but this is usually seen in children under 8 years of age, not a common concern for adult clients.

Correct Answer: B

Rationale: The correct answer is B: 'I should use my rescue inhaler when I start to experience wheezing.' A rescue inhaler is used during the onset of asthma symptoms, such as wheezing, to quickly open the airways. It is not intended for routine daily use or prevention, which is the role of a maintenance inhaler. Option A is incorrect because a rescue inhaler is not used for prevention but for immediate relief during an asthma attack. Option C is incorrect because the peak flow meter reading is used to monitor asthma control, not to determine when to use a rescue inhaler. Option D is incorrect because using a rescue inhaler only before going to bed does not address the need for immediate relief when wheezing or experiencing asthma symptoms.

Correct Answer: B

Rationale: The correct answer is B because gabapentin is prescribed to treat phantom limb pain, which is common in individuals with amputations. Option A is not the most important intervention at this time since the client is reporting physical pain, not emotional distress. Option C is not appropriate because the client is reporting aching in the foot, not the stump. Option D does not address the underlying issue of phantom limb pain that needs to be managed.

Correct Answer: C

Rationale: In sepsis with multi-organ failure, monitoring intake and output is critical to assess renal function and fluid balance, as organ failure can cause fluid shifts and decreased kidney function. Antibiotics are essential to treat the infection, but monitoring intake and output provides real-time insight into the client's status, helping to detect early signs of worsening organ function. Early ambulation and blood glucose monitoring are important aspects of care but are not as crucial as maintaining strict intake and output in this situation.

Correct Answer: B

Rationale: The correct answer is B. A hemoglobin level of 8 g/dL suggests anemia, which commonly occurs in clients with chronic kidney disease and requires prompt intervention. Reporting this finding is crucial to address the anemic condition. Choices A, C, and D are important in the context of chronic kidney disease but do not directly relate to the symptoms of fatigue and swelling in the lower extremities described in the scenario.
