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 ["2.5"]
Explanation
Identify the given information:
Volume of fluoxetine oral solution: ½ tsp
Use the conversion factor:
1 tsp = 4.929 mL
Set up the conversion:
½ tsp x (4.929 mL / 1 tsp)
½ tsp x 4.929 mL/tsp = 2.4645 mL
Round the answer to the nearest tenth:
≈ 2.5 mL
Correct Answer is ["0.65"]
Explanation
Identify the given information:
Dose of prochlorperazine: 0.13 mg/kg
Weight of the child: 55 lb
Concentration of prochlorperazine injection: 5 mg/mL
Convert the child's weight from pounds to kilograms:
1 lb ≈ 0.453592 kg
Calculate the total dose of prochlorperazine in mg:
Total dose = Dose/kg x Weight (kg)
Substitute the values:
Total dose = 0.13 mg/kg x 55 lb x (0.453592 kg/1 lb)
Total dose ≈ 3.4 mg
Calculate the volume of prochlorperazine injection to be administered:
Volume = Total dose (mg) / Concentration (mg/mL)
Substitute the values:
Volume = 3.4 mg / 5 mg/mL
Volume ≈ 0.68 mL
Round the answer to the nearest hundredth:
Volume ≈ 0.65 mL
