What does the notation QH signify in a medication schedule?

The notation QH stands for "quaque hora," a Latin term that translates to "every hour." In medical contexts, this designation is used to indicate that a medication should be administered once every hour. Understanding these abbreviations is crucial for ensuring accurate timing and dosage of medications, which can significantly affect patient outcomes. It highlights the importance of precise communication in healthcare settings, promoting safety and efficacy in medication administration. Other choices reflect different dosing schedules, but they do not accurately represent what QH signifies.
