If your doctor gave you 5 doses of medicine and advised to take one every 4 hours how long would they last:
Correct answer: B. 16 hours
- A. Two days
- B. 16 hours
- C. 20 hours
- D. 12 hours
Explanation
The correct answer is 16 hours. You begin with the first dose at hour 0. Each dose is taken 4 hours apart. Therefore, the sequence of doses occurs at hours 0, 4, 8, 12, and 16. By the time the last dose is taken (at hour 16), a total of 16 hours has passed since the first dose.Options A, C, and D are incorrect as they either exceed the time frame established by 5 doses at 4-hour intervals or do not account for all doses.
