A client with an extrapyramidal reaction receives a prescription for diphenhydramine 35 mg IM. The medication is supplied as 50 mg/mL in a 1 mL prefilled single use syringe. How many mL should the nurse give? (Enter the numerical value only. If rounding is required, round to the nearest tenth.)
The Correct Answer is ["0.7"]
The nurse should administer 0.7 mL of diphenhydramine.
Here's the calculation:
Medication dosage: 35 mg (diphenhydramine)
Medication concentration: 50 mg/mL (given on the syringe label)
We need to find the volume (mL) containing the prescribed dose (35 mg) of diphenhydramine.
Volume to administer (mL) = Dose (mg) / Concentration (mg/mL)
Volume to administer (mL) = 35 mg / 50 mg/mL
Volume to administer (mL) = 0.7 mL (round to nearest tenth)
Therefore, the nurse should administer 0.7 mL of diphenhydramine

Correct Answer is ["2000"]
Explanation
Here's how to calculate the total milligrams of ampicillin the child should receive per day:
Convert child's weight to kilograms:
Weight (kg) = Weight (lbs) / Conversion factor (lbs/kg)
Weight (kg) = 88 lbs / 2.205 lbs/kg
Weight (kg) = 40 kg (round to nearest whole number)
Calculate the total daily dosage:
Daily dosage (mg) = Dose per kg (mg/kg/day) * Weight (kg)
Daily dosage (mg) = 50 mg/kg/day * 40 kg
Daily dosage (mg) = 2000 mg
Therefore, the child should receive 2000 mg of ampicillin per day.
