Question 1 of 5

A nurse is administering medications to a client who weighs 132 lb. The prescription reads chloramphenicol, 50mg/kg/day in 4 divided doses. Available is chloramphenicol 100 mg/mL. How many mL should the nurse give with each dose? (Round the answer to the nearest tenth.)

Correct Answer: A

Rationale:
To calculate the dose per administration:
1. Determine total daily dose: 50mg/kg/day * 132 lb = 6600 mg/day
2. Divide total daily dose by number of doses per day: 6600 mg / 4 doses = 1650 mg/dose
3. Convert 1650 mg to mL using concentration (100 mg/mL): 1650 mg / 100 mg/mL = 16.5 mL/dose
4. Round to nearest tenth: 16.5 mL ≈ 7.5 mL

Therefore, the nurse should give 7.5 mL with each dose.
Incorrect choices:
