What is the correct usage frequency for a medication if the prescription states "bid"?

  1. 4 times a day

  2. Every other day

  3. 2 times a day

  4. Once a day

The correct answer is: 2 times a day

"Bid" is a Latin term that stands for "bis in die," which translates to "twice a day" in English. When a prescription states "bid," it means the medication should be taken two times a day. This frequency helps ensure a consistent level of the medication in the patient's system to maintain its therapeutic effect. Therefore, the correct answer is "2 times a day." By understanding the Latin abbreviation for prescription terms like "bid," medication aides can accurately interpret and administer medications according to the physician's instructions, ensuring the safety and well-being of the patients under their care.
