Pharmacy Technician Certification Board Practice Exam Practice Question

Correct Answer: D

Rationale: When a medication quantity is omitted from a prescription, it primarily reflects a lapse during the prescribing phase, where critical information is not communicated.

- **A: Administration** refers to errors occurring during the actual giving of the medication to the patient, which is not applicable here.
- **B: Dispensing** involves errors made by pharmacists when preparing or delivering the medication, which does not pertain to the initial omission in the prescription.
- **C: Dosage** errors relate specifically to incorrect amounts or frequencies specified, but the absence of a quantity indicates a broader issue in the prescribing process.

Thus, the omission is best categorized as a prescribing error.
