Correct Answer: C

Rationale: The correct answer is C: Fever. When a client is taking clozapine, fever can indicate serious conditions such as infection or severe reactions, which need immediate medical attention. Constipation (choice A), blurred vision (choice B), and dry mouth (choice D) are common side effects of clozapine but are not as urgent as fever. Constipation can be managed with dietary changes or medications, blurred vision can improve over time, and dry mouth can be relieved with frequent sips of water.

Correct Answer: C

Rationale: The correct answer is to monitor digoxin levels in a patient on digoxin. Digoxin is a medication commonly used to treat heart conditions, and monitoring its levels in the blood is crucial to ensure that the patient is within the therapeutic range and to prevent toxicity. Monitoring potassium levels (Choice A) is important due to the potential of digoxin-induced hypokalemia, but the primary focus should be on monitoring digoxin levels. Monitoring calcium levels (Choice B) and sodium levels (Choice D) are not directly related to digoxin therapy and are not the primary lab values of concern when administering digoxin.

Correct Answer: C

Rationale: The correct answer is C because the client stating they should only take the inhaler when feeling short of breath indicates a need for further teaching. Clients with asthma should use their inhaler as prescribed, not just when short of breath. Choices A, B, and D demonstrate good asthma management practices. Choice A indicates understanding of using the albuterol inhaler before exercise to prevent exercise-induced symptoms. Choice B mentions the importance of not overusing the inhaler, which can indicate poor asthma control. Choice D shows awareness of rinsing the mouth after using a corticosteroid inhaler to prevent oral thrush.

Correct Answer: A

Rationale: Corrected Rationale: Daily weight monitoring is crucial in managing patients with chronic heart failure as it helps assess fluid balance. Monitoring daily weight allows healthcare providers to detect any sudden weight gain, which could indicate fluid retention and worsening heart failure. This intervention helps in adjusting treatment plans promptly. Providing fluid restriction (Choice B) can be a part of managing heart failure but is not the primary intervention mentioned in the question. Administering diuretics (Choice C) is a treatment modality for heart failure but does not encompass the comprehensive approach to patient management. Monitoring intake and output (Choice D) is important but does not specifically address the direct assessment of fluid status as daily weight monitoring does.

Correct Answer: A

Rationale: A glomerular filtration rate of 14 mL/minute indicates severe kidney dysfunction, necessitating hemodialysis. The other options, BUN of 16 mg/dL, serum magnesium of 1.8 mg/dL, and serum phosphorus of 4.0 mg/dL, are within normal ranges and do not serve as indications for hemodialysis.
