Question 1 of 5
After receiving Nembutal PO at bedtime, a client is wide awake all night instead of going to sleep. What kind of adverse reaction to a drug does this situation represent?
Correct Answer: C
Rationale: The correct answer is C: Idiosyncrasy. Idiosyncrasy refers to a unique and unexpected reaction to a drug that is not related to the drug's pharmacological action. In this case, the client experiencing insomnia after taking Nembutal, a sedative, suggests an idiosyncratic reaction as it goes against the expected sedative effect.
A:
Toxic effect is incorrect because the client did not exhibit symptoms of poisoning.
B: Drug allergy is incorrect as the client's reaction is not consistent with an allergic response.
D: Drug tolerance is incorrect because the client's lack of sedation is not due to tolerance buildup.
In summary, the client's unexpected reaction to Nembutal indicates an idiosyncratic response rather than toxicity, allergy, or tolerance.
