Correct Answer is A
Explanation
The half-life of a medication is the time it takes for the concentration of the medication in the body to decrease by half. In this case, the medication has a half-life of 2 hours and a current toxic level of 40 mEq/dL. After 2 hours, the level will decrease to 20 mEq/dL. After another 2 hours (4 hours total), the level will decrease to 10 mEq/dL, which is within the normal range. However, it will take another 21 half-lives (42 hours) for the level to reach 5 mEq/dL, which is the lower end of the normal range. Therefore, it will take a total of 25 hours (4 + 21) for the medication to reach the normal range.
Option B is incorrect because it would take much longer than 24 hours for the medication to reach the normal range.
Option C is incorrect because it would only take 2 hours for the medication to decrease by half, not reach the normal range.
Option D is incorrect because it would take longer than 4 hours for the medication to reach the normal range.
