Which of the following may a pharmacist change without authorization?

The patient's age may be changed without seeking authorization because it often pertains to straightforward information regarding the individual's identification that does not alter the nature of the prescription itself. Pharmacists are responsible for ensuring that prescriptions are accurate and safe; however, minor administrative details like the patient's age can typically be adjusted as part of the normal verification process.

In contrast, altering the drug name, date of prescription, or total quantity to dispense without authorization can lead to significant implications regarding the treatment plan, medication safety, and legal compliance. Changes to these elements require thorough consideration and authorization to avoid potential patient harm or misinterpretation of the prescription's intent. Adjustments made to the drug name could lead to dispensing the wrong medication, while changes to the date could affect the validity period of the prescription. Additionally, modifying the total quantity could have serious implications on dosage regimens and patient health outcomes.
