A nurse is preparing to administer pantoprazole 7 mg PO to an infant. The amount available is pantoprazole 2 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 ["3.5"]
Identify the given information:
Dose of pantoprazole: 7 mg
Concentration of pantoprazole: 2 mg/mL
Calculate the volume of pantoprazole to be administered:
Volume = Dose (mg) / Concentration (mg/mL)
Substitute the values:
Volume = 7 mg / 2 mg/mL
Calculate the result:
Volume = 3.5 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
Correct Answer is ["300"]
Explanation
Identify the given information:
Volume of lactated Ringer's solution: 150 mL
Infusion time: 30 minutes
Convert the infusion time to hours:
30 minutes = 30/60 hours = 0.5 hours
Calculate the infusion rate in mL/hr:
Infusion rate = Volume / Time
Substitute the values:
Infusion rate = 150 mL / 0.5 hr
Calculate the result:
Infusion rate = 300 mL/hr
