The medical abbreviation meaning "three times a day" is:

1. tid

2. qid

3. qh

4. pc

The correct answer is: tid

The abbreviation "tid" stands for "ter in die," which is a Latin phrase that translates to "three times a day." This abbreviation is commonly used in medical prescriptions to indicate the frequency with which a medication should be taken. It is important for healthcare providers and patients to understand this terminology for accurate dosing schedules. The other abbreviations are used to indicate different dosing frequencies. "qid" means "four times a day," which signifies a higher frequency than needed for the question's requirement. "qh" denotes "every hour," which is a much more frequent dosage interval. Finally, "pc," short for "post cibum," means "after meals," which does not specify a frequency per day but rather a timing related to meals. Understanding these distinctions is crucial for ensuring safe and effective medication administration.
