2024 PN NCLEX Questions Nursing Practice Question
A chemical reaction between drugs prior to their administration or absorption is known as:
Correct Answer: A
Rationale: A drug incompatibility occurs when two or more drugs interact chemically before administration or absorption, potentially reducing efficacy or causing harmful effects. This is distinct from a side effect (B), which refers to unintended effects that occur after the drug is administered. An adverse event (C) encompasses any negative outcome during treatment, regardless of its cause, while an allergic response (D) specifically involves the immune system's reaction to a drug. Thus, only drug incompatibility accurately describes the interaction before administration.
