Correct Answer: B

Rationale: The correct action the nurse should take prior to administering digoxin is to assess the client's apical pulse. Digoxin is known to affect the heart rate, potentially causing bradycardia. Monitoring the client's respiratory rate (Choice A) is not directly related to administering digoxin. Reviewing the client's potassium level (Choice C) is important but not a direct prerequisite for administering digoxin. Monitoring the client's fluid intake (Choice D) is also important but not a specific action to take just before administering digoxin.

Correct Answer: D

Rationale: The correct answer is D. An elevated WBC count can indicate a potential infection, especially in a postoperative client. This finding should be reported to the provider for further evaluation and management. Choices A, B, and C are common occurrences in postoperative clients and may not necessarily indicate a severe issue. Serosanguineous drainage on the surgical dressing is a normal finding in the immediate postoperative period. A temperature of 37.8°C (100°F) can be a mild fever, which is common postoperatively due to the body's response to tissue injury. Urine output of 75 mL in the past 4 hours may be within normal limits for a postoperative client, especially if they are still recovering from anesthesia.

Correct Answer: D

Rationale: The correct action for the nurse to take when caring for a client with schizophrenia who is pacing the hall and agitated is to walk with the client at a gradually slower pace. This approach can help reduce the client's agitation and prevent the situation from escalating. Choice A is incorrect because directly asking about harm may increase the client's anxiety. Choice B is inappropriate as it may worsen the client's agitation. Choice C is not recommended as the client may benefit from the nurse's presence and support during this time of distress.

Correct Answer: B

Rationale: The correct answer is B. The nonstress test typically takes about 10 minutes and evaluates the fetal heart rate in response to fetal movement. Having a full bladder or fasting for 12 hours is not required for a nonstress test. Checking blood glucose levels is not part of the nonstress test procedure.

Correct Answer: B

Rationale: The correct answer is B. Alendronate should be taken with a full glass of water before breakfast to prevent esophageal irritation and improve absorption. Choice A is incorrect as alendronate is not associated with causing drowsiness. Choice C is incorrect because alendronate can be taken with or without food, so avoiding dairy products is not necessary. Choice D is incorrect as the recommended time to remain upright after taking alendronate is 30 minutes to 1 hour, not just 30 minutes.
