What abbreviation indicates that medication should be administered every hour?

The abbreviation that indicates that medication should be administered every hour is "qh." This stands for "quaque hora," which is Latin for "every hour." It is commonly used in medical prescriptions to specify the frequency of drug administration. For example, if a doctor writes a prescription with this instruction, it means the patient should take the medication once every hour throughout the day.

Other abbreviations, while important in the context of medication administration, denote different frequencies. "qid" means "four times a day," indicating that the medication should be taken four times within a 24-hour period, usually at evenly spaced intervals. "bid" stands for "twice a day," instructing patients to take the medication two times in a day. "ac" refers to "before meals," indicating the timing related to food intake rather than the frequency of dosing. Understanding these abbreviations is crucial for ensuring correct medication administration and patient safety.
