West Virginia MPJE (Pharmacy Jurisprudence) Practice Exam

For all scheduled drugs, what three items on the prescription cannot be changed?

1. Drug strength, dosage form, and quantity prescribed

2. Patient's name, drug (except for generic substitution), and prescriber's signature

3. Prescriber's address, patient's address, and drug quantity

4. Refill amount, drug name, and prescriber's DEA number

The correct answer is: Drug strength, dosage form, and quantity prescribed

For all scheduled drugs, the three items on the prescription that cannot be changed are the drug strength, dosage form, and quantity prescribed. These elements are crucial for ensuring the patient receives the appropriate medication in the correct amount and formulation as determined by the prescriber. Making changes to these key components could result in potential medication errors or pose risks to the patient's health. Option B, the patient's name, drug (except for generic substitution), and prescriber's signature, are important parts of the prescription but are not among the three items that cannot be changed for scheduled drugs. Prescriber's address, patient's address, and drug quantity (Option C) can be modified if necessary. Option D, refill amount, drug name, and prescriber's DEA number, contains elements that may be subject to change under certain circumstances, unlike the three critical items specified in the correct answer.
