Question

when a patient does not follow a dosing regimen, it is called a(n):
a. improper dose error.
b. deteriorated drug error.
c. adherence error.
d. wrong dosage form error.

Explanation:

To solve this, we analyze each option:

• Option A: Improper dose error relates to incorrect dosage amount, not non - adherence to the regimen.
• Option B: Deteriorated drug error is about the drug's quality (like expiration or degradation), not following the regimen.
• Option C: Adherence error is defined as a patient not following the prescribed dosing regimen, which matches the description in the question.
• Option D: Wrong dosage form error is about using the wrong form of the drug (e.g., tablet instead of liquid), not non - adherence.

Answer:

C. adherence error.
