Answer:
(c) four times a day.
Step-by-step explanation:
In pharmaceutical terminology:
"qid" stands for "quater in die," which is Latin for "four times a day."
This means that a medication should be taken four times a day, typically at evenly spaced intervals, such as every six hours.
This dosing schedule is commonly used for medications that require frequent administration to maintain a consistent level of the drug in the patient's system, especially for conditions that require continuous treatment or control throughout the day.
