A nurse is preparing to administer a liquid medication with a concentration of 250 mg/5 mL. The prescribed dose is 500 mg. How many mL of the medication should the nurse administer?
5 mL
10 mL
15 mL
20 mL
The Correct Answer is B
To calculate the volume of a liquid medication to administer based on its concentration and the prescribed dose, the nurse should divide the prescribed dose by the concentration and multiply by the volume in which the concentration is expressed. In this case, the concentration is 250 mg/5 mL and the prescribed dose is 500 mg, so the nurse should administer (500 mg / 250 mg) x 5 mL = 10 mL of the medication.

Correct Answer is A
Explanation
To calculate the volume of liquid medication to administer based on its concentration and prescribed dose, the nurse should divide the prescribed dose by concentration and multiply by the volume in which concentration is expressed. In this case, the concentration is 250 mg/5mL and the prescribed dose is 750 mg so, the nurse should administer(750mg/250mg)x5mL=15mL of medication. Since 1 tsp is equivalent to 5mL, the nurse should administer 15mL/5mL/tsp=3tsp of medication.
Correct Answer is B
Explanation
Step 1: 6 mL ÷ 3 min
Answer: 2 mL/min
