What does "hr" stand for in medication administration?

In medication administration, "hr" stands for "hour." This abbreviation is commonly used in medical and pharmaceutical contexts to indicate the timing of doses. For example, medication might be prescribed to be taken every "hr" to ensure that the patient receives the medication at the right intervals for effectiveness. Understanding this abbreviation is crucial for proper medication management and scheduling, as it helps caregivers to maintain consistent administration times, which can be vital for certain medications to work effectively.

The other options provided do not convey the standard meaning of "hr" in the context of medication. "Half" does not correspond to a recognized unit of time in this scenario, while "high risk" refers to a category of medications that may require special precautions, and "hygiene required" is not a commonly accepted abbreviation in medication administration. Thus, recognizing that "hr" signifies "hour" is critical for safe and proper medication practices.
