A nurse is caring for client who has sepsis and a prescription for vancomycin 1 g in 250 mL dextrose 5% (DSW) over 2 hr by IV intermittent bolus. The nurse should set the IV pump to deliver how many mL/hr? (Round the answer to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
The Correct Answer is ["125"]
Understanding the Problem
We need to administer 250 mL of solution over 2 hours.
We need to calculate the infusion rate in mL/hr.
Calculations
Convert hours to minutes (optional, but can help visualize):
2 hours = 2 X 60 minutes = 120 minutes
Calculate the infusion rate:
Infusion rate (mL/hr) = Total volume (mL) / Time (hr)
Infusion rate = 250 mL / 2 hr = 125 mL/hr
Answer
The nurse should set the IV pump to deliver 125 mL/hr.

Correct Answer is ["167"]
Explanation
Convert pounds to kilograms: 245 lbs / 2.2 lbs/kg = 111.36 kg
Calculate the enoxaparin dose: 1.5 mg/kg X 111.36 kg = 167.04 mg
Round to the nearest whole number: 167 mg
Therefore, the nurse should administer 167 mg of enoxaparin per dose.
Correct Answer is ["24"]
Explanation
We need to deliver 1200 units of heparin per hour.
The bag contains 25,000 units of heparin in 500 mL of D5W.
To find the mL/hr needed to deliver 1200 units/hr, we can use the following formula:
(Desired dose in units/hr) / (Concentration of heparin in units/mL) = mL/hr
First, we need to find the concentration of heparin in the solution:
25,000 units / 500 mL = 50 units/mL
Now, we can calculate the infusion rate:
1200 units/hr / 50 units/mL = 24 mL/hr
