Which of the following is NOT an example of an error in dispensing?

Correctly following the prescription terms is indeed an example of not making an error in dispensing. When a pharmacist adheres to the specific instructions provided by the prescriber—such as the medication name, dosage, quantity, and directions for use—they are executing their responsibility accurately. This alignment with the prescription is essential to ensure patient safety and therapeutic effectiveness.

In contrast, other options illustrate scenarios that constitute dispensing errors. For instance, dispensing a quantity less than prescribed compromises the patient's treatment plan by providing insufficient medication. Providing an unapproved label may lead to patient confusion or misuse, which poses significant risks. Illegally substituting one medication for another without the prescriber's consent also represents a serious violation of professional standards and can have dangerous consequences for the patient. Each of these scenarios highlights a failure in the dispensing process, while correctly following prescription terms represents the necessary standard for a safe and effective pharmacy practice.
