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 ["4.8"]
Explanation
The vial is labeled as “100 mg per 4 mL.”
This means that each mL contains 25 mg of the medication (100 mg / 4 mL = 25 mg/mL).
The nurse needs to administer 120 mg of the medication.
To find out how many mL this is, we divide the dose by the concentration:
VolumeinmL = 120mg / 25mg/mL = 4.8mL
If rounding is required to the nearest tenth, the nurse should administer 4.8 mL of the medication.
Correct Answer is ["2000"]
Explanation
Here's how to calculate the total milligrams of ampicillin the child should receive per day:
Convert child's weight to kilograms:
Weight (kg) = Weight (lbs) / Conversion factor (lbs/kg)
Weight (kg) = 88 lbs / 2.205 lbs/kg
Weight (kg) = 40 kg (round to nearest whole number)
Calculate the total daily dosage:
Daily dosage (mg) = Dose per kg (mg/kg/day) * Weight (kg)
Daily dosage (mg) = 50 mg/kg/day * 40 kg
Daily dosage (mg) = 2000 mg
Therefore, the child should receive 2000 mg of ampicillin per day.
