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?

Toxic effect

Drug allergy

Idiosyncrasy

Drug tolerance

Answer and Explanation

The Correct Answer is C

Choice A reason: Toxic effects involve overdose symptoms like coma; staying awake isn’t toxicity, as Nembutal’s sedative intent is reversed, not exaggerated, in this reaction.

Choice B reason: Drug allergy causes immune responses (e.g., rash); insomnia isn’t allergic, but a paradoxical effect, differing from hypersensitivity reactions entirely.

Choice C reason: Idiosyncrasy is an unexpected reaction; Nembutal, a barbiturate, should sedate, but wakefulness is an abnormal, individual response, fitting this category precisely.

Choice D reason: Tolerance reduces efficacy over time; this acute, opposite reaction to a sedative isn’t tolerance, but an immediate, unpredictable drug response.

Correct Answer is A

Explanation

Choice A reason: Consulting ensures safety; not all drugs can be altered, and the provider adjusts the order, preventing errors in bioavailability or efficacy.

Choice B reason: Liquid may work, but without approval, it’s unauthorized; some drugs lack liquid forms, and this bypasses necessary prescriber oversight.

Choice C reason: Parenteral needs an order change; administering without it violates scope, and it’s invasive, escalating care unnecessarily as a first step.

Choice D reason: Crushing alters pharmacokinetics; many tablets (e.g., extended-release) can’t be crushed, and doing so without checking risks toxicity or inefficacy.

A. After showing the drug label to the client B. Before returning the drug container to the client’s medication drawer C. Before calling the pharmacy D. After checking the drug container with a colleague

Correct Answer is B

Explanation

Choice A reason: Showing the client isn’t a standard check; patients don’t verify MAR, and this step lacks relevance to the nurse’s triple-check safety protocol.

Choice B reason: Checking before returning ensures accuracy; the third check confirms the right drug post-administration, completing the three-point verification process safely.

Choice C reason: Calling the pharmacy is unrelated; label checks occur during administration, not external consultation, making this an irrelevant timing option.

Choice D reason: Colleague checks aren’t routine; the three checks are individual, and this step doesn’t align with standard MAR verification timing protocols.
