While precepting a new nurse, which abbreviation indicates a need for further teaching?

The abbreviation "q.d." stands for "quaque die," which translates to "once a day." The use of "q.d." is discouraged in medical practice due to the potential for misinterpretation, especially when handwritten. Miscommunication regarding medication administration frequency can lead to serious medication errors, making it crucial for healthcare professionals to use abbreviations that are clear and universally understood.

In contrast, "mcg" stands for micrograms, "mL" refers to milliliters, and "PO" is an abbreviation for "per os," meaning by mouth. These abbreviations are widely accepted and recognized within the healthcare community. As a result, they do not pose the same risk for misunderstanding or error as "q.d." does, highlighting the need for clarity in communication among healthcare providers, especially in situations involving medication administration.
