What is the abbreviation for the term "every" in medical notation?

The abbreviation for "every" in medical notation is represented by the letter "q." This abbreviation originates from the Latin word "quaque," which means "every." It is commonly used in prescriptions and medical documentation to indicate the frequency of medication administration or medical procedures.

In contrast, the other options represent more specific frequencies and may include additional context. For instance, "qd" stands for "quaque die," which means "every day," whereas "qod" means "every other day." "q2h" indicates that something should occur "every two hours." Therefore, the choice of just "q" is a general representation for "every," which makes it the correct abbreviation in this context.
