Correct Answer: C

Rationale: The correct way to monitor a patient who has been prescribed digoxin is by checking digoxin levels. Digoxin is a medication used to treat various heart conditions, and monitoring its levels in the blood is crucial to prevent toxicity. Monitoring potassium levels (Choice A) is important as well, as digoxin can affect potassium levels, but checking digoxin levels is more specific to monitoring the medication itself. Monitoring heart rate (Choice B) is relevant but does not directly assess the medication levels. Checking blood glucose levels (Choice D) is not typically indicated specifically for patients prescribed digoxin.

Correct Answer: C

Rationale: A respiratory rate of 26/min is a sign of respiratory distress and should be reported promptly in a client with pneumonia. Rapid breathing can indicate inadequate oxygenation and ventilation, which may lead to respiratory failure. Crackles in the lung bases are common in pneumonia but may not be as urgent as a high respiratory rate. A blood pressure of 100/64 mm Hg is slightly low but may not be immediately life-threatening. A heart rate of 86/min is within the normal range for an adult and is not the most critical finding to report.

Correct Answer: B

Rationale: The correct answer is B: 'Avoid lying down after meals.' This instruction is important for clients with GERD to prevent acid reflux. Lying down after meals can worsen GERD symptoms by allowing stomach acid to flow back into the esophagus. Choices A, C, and D are incorrect. Choice A is incorrect because lying flat after meals can increase the risk of acid reflux. Choice C is incorrect because hot liquids may aggravate GERD symptoms. Choice D is incorrect because consuming a high-carbohydrate snack at bedtime can also trigger acid reflux in individuals with GERD.

Correct Answer: D

Rationale: Clients diagnosed with tuberculosis should be placed in a negative pressure room to prevent the spread of airborne pathogens. Option A is incorrect because administering isoniazid is a treatment for tuberculosis, not a preventive measure related to infection control. Option B is incorrect as droplet isolation is used for diseases transmitted through respiratory droplets, not airborne pathogens like tuberculosis. Option C is incorrect as wearing a surgical mask is not sufficient to prevent the spread of tuberculosis in healthcare settings; placing the client in a negative pressure room is the most effective measure.

Correct Answer: B

Rationale: The correct answer is B: Tachycardia. In acute alcohol withdrawal, tachycardia is a common finding due to increased sympathetic activity. Bradycardia (Choice A) is less likely in this condition since the sympathetic nervous system is typically overactive. Hyperthermia (Choice C) is not a typical finding in acute alcohol withdrawal. Hypotension (Choice D) is less common compared to tachycardia in this situation.
