Practice Question

The healthcare provider prescribes acyclovir 800 mg by mouth (PO) every 6 hours for an adolescent with chicken pox. The medication is available in 400 mg tablets PO. How many tablets should the nurse administer to the client every 24 hours? (Enter the numeric value only.)

Answer Choices:

Correct Answer:

8

Rationale:

📘Step 1: Determine how many doses the client receives in 24 hours.

Every 6 hours = 4 doses per day

📘 Step 2: Each dose is 800 mg.

Total daily dose = 800 mg × 4 = 3,200 mg/day

📘 Step 3: Each tablet is 400 mg, so:

3,200 mg ÷ 400 mg/tablet

8 tablets/day
