A patient develops nausea after receiving a prescribed medicine, but the symptom is mild and expected with that drug. How should the nurse classify this finding?
Correct answer: B. Expected adverse effect
- A. Therapeutic effect
- B. Expected adverse effect
- C. Idiosyncratic reaction
- D. Drug withdrawal effect
Explanation
A predictable, unwanted response occurring at a usual dose is an adverse effect. An idiosyncratic reaction is unusual and unpredictable, while withdrawal effects occur after reducing or stopping a drug that has caused physical dependence.
