Which of the following is a requirement for unit dose packaging?

Unit dose packaging is designed to ensure safe and effective medication administration, particularly in institutional settings like hospitals. One key requirement for unit dose packaging is that it must clearly identify the manufacturer’s name. This is important because it helps healthcare providers trace the medication back to its source, ensuring quality control and accountability. It also aids in identifying specific formulations, potential allergies, and recalls.

The other options, while important in various contexts, do not meet the specific legal requirements of unit dose packaging. For example, a patient's phone number is not relevant to the packaging of medications for distribution; rather, it's part of patient records. Directions for use, while important for patient understanding, are typically found in the accompanying documentation or in a package insert, rather than directly on the unit dose itself. Similarly, a pharmacist's signature is not a standard requirement for unit dose packaging, although it may be involved in the overall dispensing process. Thus, the focus on the manufacturer's name emphasizes the importance of accountability and traceability in medication distribution.
