Correct Answer: A

Rationale: Visual disturbances, such as yellow-tinged vision or seeing halos around lights, are common signs of digoxin toxicity. These symptoms should be reported immediately to healthcare providers for further evaluation and management.

Warfarin works by inhibiting vitamin K-dependent clotting factors, and administering vitamin K can replenish these factors, thereby counteracting the anticoagulant effects of Warfarin.

Correct Answer: A

Rationale: Visual disturbances, such as yellow-tinged vision or seeing halos around lights, are common signs of digoxin toxicity. These symptoms should be reported immediately to healthcare providers for further evaluation and management.

Correct Answer: A

Rationale: Amphotericin B is known to cause nephrotoxicity, a potential adverse effect that can be monitored by checking the client's serum creatinine levels. Regular monitoring of serum creatinine helps in early identification of kidney damage and allows for timely intervention to prevent further complications.

Correct Answer: C

Rationale: The correct answer is C. Changing positions slowly can help prevent orthostatic hypotension, a common adverse effect of tricyclic antidepressants like Amitriptyline. It is essential to educate the client to avoid sudden position changes to minimize the risk of dizziness and falls. Choices A, B, and D are incorrect. Therapeutic effects of Amitriptyline may not be noticeable for 1-3 weeks, so expecting them in 24 to 48 hours (choice A) is unrealistic. Discontinuing the medication abruptly can lead to withdrawal symptoms and should be done gradually under healthcare provider supervision, so choice B is incorrect. Amitriptyline can actually cause constipation, so decreasing dietary fiber intake would not be recommended to control diarrhea, making choice D incorrect.
