Question 1 of 5
The client diagnosed with chronic obstructive pulmonary disease is being discharged and is prescribed the steroid prednisone. Which scientific rationale supports why the nurse instructs the client to taper off the medication?
Correct Answer: C
Rationale: Prednisone suppresses adrenal cortisol production; tapering allows adrenal glands to resume function, preventing adrenal crisis.
Question 2 of 5
A client is receiving digitalis. The nurse should instruct the client to report which of the following side effects?
Correct Answer: A
Rationale: Nausea, vomiting, fatigue. Side effects of digitalis toxicity include fatigue, nausea, vomiting, anorexia, and bradycardia. Digitalis inhibits the sodium potassium ATPase, which makes more calcium available for contractile proteins, resulting in increased cardiac output.

The male client comes to the emergency department and reports he stepped on a rusty nail at home about two (2) hours ago. Which question would be most important for the nurse to ask during the admission assessment?
