2024 PN NCLEX Questions Nursing Practice Question
An allergic reaction is classified as what type of pharmacological effect?
Correct Answer: C
Rationale: An allergic reaction is classified as an adverse effect, as it represents an unintended and harmful response to a medication or substance.
Option A, a therapeutic effect, refers to the intended and beneficial outcomes of a drug, which does not apply to allergic reactions. Option B, a side effect, typically describes mild, non-harmful effects that occur alongside the therapeutic effect but do not include severe allergic responses. Option D, an incompatibility, pertains to interactions between drugs that can lead to ineffective treatment or harmful reactions but does not specifically address the immune response involved in allergies.
