The nurse prepares to administer promethazine 35 mg intramuscularly prescribed as needed for a client with cholecystitis who has severe nausea. The ampule label reads that the medication is available in 25 mg/mL. How many milliliters should the nurse administer?
Record your answer using one decimal place.
1
1.4
1.5
0.7
The Correct Answer is B
Choice A rationale: this corresponds with 25 mg which is lower than the prescribed amount.
Choice B rationale: To answer this question, we need to use the formula: volume (mL) = dose (mg) / concentration (mg/mL). We plug in the given values: volume (mL) = 35 mg / 25 mg/mL. We simplify the fraction: volume (mL) = 7/5. We convert the fraction to a
decimal: volume (mL) = 1.4. Therefore, the nurse should administer 1.4 mL of promethazine.
Choice C rationale: this corresponds with 37.5 mg which is too high.
Choice D rationale: this corresponds with 17.5 mg which is too low.
