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 ["75"]
Explanation
The prescribed dosage is 15 mL every 12 hours, so the total daily dosage in mL would be:
DailydosageinmL = 2 × Dosageperdose = 2 ×15mL = 30mL
The medication is available in a concentration of 12.5 mg/5 mL. Therefore, the total daily dosage in mg would be:
Dailydosageinmg=DailydosageinmL×Concentrationinmg/mL=30mL×5mL12.5mg=75mg
So, the client receives a total daily dose of 75 mg of diphenhydramine.
Correct Answer is ["0.4"]
Explanation
Here's the breakdown of the calculation:
The medication vial is labeled 1,200,000 units/2 mL, which means there are 1,200,000 units of penicillin G per every 2 mL of the medication.
We need to find out how many mL are needed to administer the prescribed dose of 240,000 units.
To do this, we can divide the desired dose (240,000 units) by the concentration of the medication (units per mL).
Calculation:
Dose per mL = 1,200,000 units / 2 mL = 600,000 units/mL
Desired dose / Dose per mL = 240,000 units / 600,000 units/mL = 0.4 mL
Rounding to the nearest tenth, the nurse should administer 0.4 mL of Penicillin G procaine.
