Correct Answer is ["300"]
Explanation
Understanding the problem
We need to administer 150 mL of the medication over 30 minutes.
We need to determine the flow rate in mL/hr.
Step-by-step calculation
Convert minutes to hours:
30 minutes = 0.5 hours
Calculate the flow rate:
Flow rate (mL/hr) = Total volume (mL) / Infusion time (hours) = 150 mL / 0.5 hours = 300 mL/hr
Therefore, the nurse should set the IV pump to deliver 300 mL/hr.
Correct Answer is ["8"]
Explanation
Understanding the problem
We need to administer 2g of nafcillin.
The reconstituted solution has a concentration of 250 mg/mL.
We need to determine the volume to administer.
Step-by-step calculation
Convert grams to milligrams:
2 g = 2000 mg
Use the formula:
Volume (mL) = Desired dose (mg) / Concentration (mg/mL) = 2000 mg / 250 mg/mL
Calculate the volume:
Volume (mL) = 8 mL
Therefore, the nurse should administer 8 mL of the reconstituted nafcillin solution.
