A nurse is preparing to administer midazolam 3 mg IM to a child. The amount available is midazalam solution 5 mg/mL. How many mL should the nurse administer? (Round the answer to the nearest tenth. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["0.6"]
Identify the given information:
Dose of midazolam: 3 mg
Concentration of midazolam solution: 5 mg/mL
Calculate the volume of midazolam to be administered:
Volume = Dose (mg) / Concentration (mg/mL)
Substitute the values:
Volume = 3 mg / 5 mg/mL
Calculate the result:
Volume = 0.6 mL

Correct Answer is ["1.9"]
Explanation
Identify the given information:
Dose of nafcillin: 25 mg/kg/day
Weight of the child: 83 lb
Concentration of nafcillin injection: 250 mg/mL
Convert the child's weight from pounds to kilograms:
1 lb ≈ 0.453592 kg
Calculate the total daily dose of nafcillin in mg:
Total daily dose = Dose/kg/day x Weight (kg)
Substitute the values:
Total daily dose = 25 mg/kg/day x 83 lb x (0.453592 kg/1 lb)
Total daily dose ≈ 936.82 mg
Calculate the dose per dose (every 12 hours):
Dose per dose = Total daily dose / 2
Substitute the values:
Dose per dose = 936.82 mg / 2
Dose per dose ≈ 468.41 mg
Calculate the volume of nafcillin injection to be administered:
Volume = Dose per dose (mg) / Concentration (mg/mL)
Substitute the values:
Volume = 468.41 mg / 250 mg/mL
Volume ≈ 1.87 mL
Round the answer to the nearest tenth:
Volume ≈ 1.9 mL
Correct Answer is ["120"]
Explanation
Step-by-Step Solution:
Determine the total infusion time in hours.
The infusion time is 20 minutes.
There are 60 minutes in an hour.
The infusion time in hours = 20 minutes / 60 minutes/hour = 0.3333 hours.
Calculate the infusion rate in mL/hr.
The total volume to be infused is 40 mL.
The infusion time is 0.3333 hours.
The infusion rate = 40 mL / 0.3333 hours = 120 mL/hr.
