2024 PN NCLEX Questions Nursing Practice Question
When medications have an additive, synergistic, or antagonistic effect on a tissue, a reaction has occurred.
Correct Answer: B
Rationale: When medications exert additive, synergistic, or antagonistic effects on a tissue, they are interacting at the site of action, which is described by pharmacodynamics. This field studies how drugs affect the body and their mechanisms of action.
Option A, pharmaceutical, refers to the formulation and preparation of drugs, not their effects. Option C, pharmacokinetic, deals with how the body absorbs, distributes, metabolizes, and excretes drugs, focusing on the drug's journey rather than its effects on tissues. Option D, drug incompatibility, pertains to chemical interactions that occur outside the body, often affecting drug stability rather than physiological responses.
