Question

a qid.
b ac and bedtime.
c pc and bedtime.
d every 6 hours.

Explanation:

Step1: Calculate time between doses

$\frac{24}{4} = 6$ hours

Step2: Match to options

Both A (QID, meaning 4 times daily) and D fit the 4 doses over 24 hours, but the question asks for the exact schedule to implement, which is every 6 hours as it explicitly defines the timing between doses.

Answer:

D. Every 6 hours.
