If a medication is to be given every 4 hours, what would be the appropriate abbreviation?

The abbreviation for "every 4 hours" is expressed as "q4." This nomenclature stems from the Latin term "quaque," which means "every." When it is combined with the number four, it clearly conveys the intended dosing schedule of taking the medication four times a day at regular intervals of four hours.

Using correct abbreviations in medication dosing is crucial for avoiding misunderstandings that could lead to medication errors. In this situation, "q4" specifically communicates the frequency that the medication should be administered, aligning with standard medical practices.

The other options represent different concepts: "q6" would indicate every six hours, "hs" is used for medications that are to be given at bedtime (from the Latin "hora somni"), and "stat" denotes an immediate need for medication. Understanding these abbreviations helps ensure proper communication in healthcare settings.
