What does the abbreviation 'q.h.' represent?

The abbreviation 'q.h.' stands for "quaque hora," which is Latin for "every hour." This term is frequently used in medical prescriptions and documentation to indicate that a certain medication or treatment should be administered at hourly intervals. Understanding this abbreviation is important for medical assistants, as it ensures proper timing and adherence to medication schedules, which can be critical for patient care and treatment effectiveness.

The other options, while relevant in medical terminology, do not accurately capture the meaning of 'q.h.': "Every" is too vague without a specified interval, "Without" does not relate to frequency, and "Subcutaneous" refers specifically to a method of drug administration rather than a timing schedule. Hence, the correct interpretation of 'q.h.' as "every hour" is essential in the context of medical practices.
