Correct Answer is ["75 "]
Explanation
- Formula: Dose (mg) = Volume (mL) x Concentration (mg/mL)
- Solution:
- Dose (mg) = 15 mL x (12.5 mg / 5 mL)
- Dose (mg) = 15 mL x 2.5 mg/mL
- Dose (mg) = 37.5 mg
- Answer: The client receives 37.5 mg of diphenhydramine every 12 hours PRN for pruritus.
The total daily dose in mg is 37.5 x 2 = 75 mg.
Correct Answer is ["0.64 mL"]
Explanation
- Calculate the dose of methylprednisolone in mL using the formula: Dose (mL) = Ordered Dose (mg) / Available Dose (mg) x Available Volume (mL)
- Substitute the values from the question: Dose (mL) = 40 mg / 125 mg x 2 mL
- Simplify the expression: Dose (mL) = 0.64 mL
- Round to the nearest hundredth if needed: Dose (mL) = 0.64 mL
- The nurse should administer 0.64 mL of medication.
