The healthcare provider prescribes a hydration IV of normal saline to run over 3 hours at 30 mL/kg for a client who is dehydrated and weighs 154 pounds. The nurse should program the infusion pump to deliver how many mL/hour? (Enter numeric value only.)
The Correct Answer is ["699"]
First, we need to convert the client’s weight from pounds to kilograms since the dosage is prescribed in mL/kg.
We know that 1 kg is approximately 2.20462 pounds. So,
Weight in kg= Weight in pounds/2.20462 = 154 / 2.20462 ≈ 69.85kg
The prescribed dosage is 30 mL/kg, so the total volume in mL would be:
Volume in mL= Dosage per kg × Weight in kg=30mL/kg × 69.85kg ≈ 2095.5mL
The medication is to be administered over 3 hours. Therefore, the rate in mL/hour would be:
Rate in mL/hour = Volume in mL / Time in hours = 2095.5mL/3hours ≈ 698.5mL/hour
So, the nurse should program the infusion pump to deliver approximately 699 mL/hour.

Correct Answer is ["0.4"]
Explanation
Here's how to calculate the volume (mL) of ketorolac the nurse should administer:
1. We know:
Dose of ketorolac to administer: 12 mg (given)
Concentration of ketorolac in the vial: 30 mg/mL (given)
2. We need to find:
Volume to administer (mL)
3. Calculation:
Volume (mL) = Dose (mg) / Concentration (mg/mL)
Volume (mL) = 12 mg / 30 mg/mL
Volume (mL) = 0.4 mL (round to one decimal place as appropriate for medication administration)
Therefore, the nurse should administer 0.4 mL of ketorolac.
Correct Answer is ["12","000"]
Explanation
Here's the calculation for how many heparin units the client will receive in 12 hours:
Heparin concentration: The concentration of the heparin solution is 20,000 units in 500 mL (given). This translates to 40 units/mL (concentration = total units / volume).
Infusion rate: The client is receiving the solution at a rate of 25 mL/hour (given).
Time: We need to find the total heparin units received over 12 hours.
Calculation:
Find the total volume of the solution infused in 12 hours:
Total volume (mL) = Rate (mL/hour) x Time (hours)
Total volume (mL) = 25 mL/hour x 12 hours
Total volume (mL) = 300 mL
Find the total heparin units delivered in the infused volume:
Total heparin units = Volume of solution (mL) x Concentration (units/mL)
Total heparin units = 300 mL x 40 units/mL
Total heparin units = 12,000 units
Therefore, the client will receive 12,000 units of heparin in 12 hours.
