Correct Answer: B

Rationale: When an older adult with aspiration pneumonia coughs while attempting to drink, it may indicate aspiration. Aspiration can lead to serious complications. Therefore, the appropriate intervention for the nurse in this situation is to stop feeding immediately and assess the client for signs of aspiration. Encouraging the client to drink more slowly (Choice A) may not address the risk of aspiration. Elevating the head of the bed further (Choice C) is generally beneficial to prevent aspiration but is not the priority when immediate assessment is needed. Teaching coughing and deep breathing exercises (Choice D) is not appropriate when the client is actively coughing during feeding and requires immediate assessment for potential aspiration.

Correct Answer: B

Rationale: A decrease in white blood cell count indicates that the infection is responding to treatment and the client's condition is improving. Monitoring the white blood cell count is a more objective indicator of the body's response to the antibiotics. Choices A, C, and D may also be positive signs, but they are less specific and may vary among individuals. Respiratory rate alone may not be sufficient to indicate improvement, as other factors can influence it. Energy levels and cough characteristics are subjective and may not always correlate with the effectiveness of antibiotic treatment.

Correct Answer: B

Rationale: The correct answer is to monitor the client's heart rate. Digoxin slows the heart rate, so it is crucial to assess the heart rate before administering the medication. If the heart rate is below 60 beats per minute, the dose should be held, and the healthcare provider should be notified. Checking the blood pressure (Choice A) is important but not as crucial as monitoring the heart rate in this case. Assessing the respiratory rate (Choice C) is not directly related to the action of digoxin. Reviewing the client's potassium level (Choice D) is important for clients taking digoxin due to the risk of hypokalemia, but assessing the heart rate takes priority.

Correct Answer: B

Rationale: In a client with adrenal crisis presenting with a high temperature, tachycardia, and hypotension, the priority action for the nurse to implement first is to infuse an intravenous fluid bolus. This intervention aims to address the hypotension by increasing the circulating volume and improving perfusion. Obtaining an analgesic prescription (Choice A) is not the priority in this situation. Administering an oral antipyretic (Choice C) may help reduce the fever but does not address the primary issue of hypotension. Covering the client with a cooling blanket (Choice D) may help with temperature control but does not address the hemodynamic instability caused by the adrenal crisis.

Correct Answer: B

Rationale: The correct answer is B. Alendronate (Fosamax) should be taken with a full glass of water in the morning to prevent esophageal irritation and ensure proper absorption. Choice A is incorrect because taking alendronate at bedtime increases the risk of esophageal irritation due to lying down. Choice C is incorrect because patients should remain upright for at least 30 minutes after taking alendronate to prevent esophageal irritation. Choice D is incorrect because alendronate should be taken on an empty stomach, not with food, to enhance absorption.
