A patient needs 250 mg of a drug. Each tablet contains 50 mg. How many tablets are needed?
Answer and explanation
Correct answer: C. 5 tablets
- Step 1: Number of tablets = total dose / dose per tablet. Step 2. 250 / 50 = 5. Answer: 5 tablets. Why not the others: 125 tablets: mass and tablet strength were multiplied. 1 tablets: the number was doubled. 2 tablets: the tablet strength was subtracted.
