A medication label reads: "Take one tablet every 4 to 6 hours. Do not take more than 3 tablets in 12 hours. Take each tablet with 8 ounces of water. Check back with your doctor if symptoms are not relieved in 2 days." Based on this label, which of the following dosing schedules should the person follow?

Answer

6am, 11am, 3pm, 7pm

Rationale

The label requires doses spaced 4 to 6 hours apart, with no more than 3 tablets taken in any 12-hour period. The schedule 6am, 11am, 3pm, 7pm satisfies both constraints: each dose is 4-5 hours after the previous one, and within any rolling 12-hour window only 3 tablets are taken (e.g., 6am-6pm includes 6am, 11am, 3pm = 3 tablets), matching the maximum allowed.

Answer choices

• A. 7am, 9am, 11am, 1pm (four doses spaced 2 hours apart)

• B. 6am, 11am, 3pm, 7pm
