The healthcare provider prescribes a liter of normal saline IV to be infused over 9 hours for a client who is NPO. The nurse should program the infusion pump to deliver how many mL/hour? (Enter numeric value only. If rounding is required, round to the nearest whole number).
The Correct Answer is ["111"]
Here's how to calculate the rate for the infusion pump:
Total volume to infuse: 1 liter (given)
Infusion time: 9 hours (given)
We need to find the volume delivered per hour (mL/hour) considering the total volume and infusion time.
Volume conversion: Since the volume is given in liters, convert it to mL:
1 liter * 1000 mL/liter = 1000 mL
Infusion rate (mL/hour):
Infusion rate (mL/hour) = Total volume (mL) / Infusion time (hours)
Infusion rate (mL/hour) = 1000 mL / 9 hours
Infusion rate (mL/hour) = 111.11 mL/hour (round to nearest tenth)
Therefore, the nurse should program the infusion pump to deliver approximately 111 mL/hour.

Correct Answer is ["59.147"]
Explanation
Here's how to calculate the number of mL the nurse should document:
Client dosage: 2 ounces (given)
Conversion factor: 1 ounce (oz) = 29.5735 mL (conversion factor)
Magnesium hydroxide concentration: 400 mg per 5 mL (from bottle label)
We need to find the equivalent volume in mL of the 2 ounces dosage the client reported.
Steps:
a. Convert ounces to mL:
Client dosage (mL) = Client dosage (oz) x Conversion factor (mL/oz)
Client dosage (mL) = 2 oz * 29.5735 mL/oz
Client dosage (mL) = 59.147 mL (round to nearest hundredth)
Correct Answer is ["0.29"]
Explanation
Here's how to calculate the volume (mL) of epoetin alfa the nurse should administer:
1. Client weight conversion:
Client weight: 126 pounds
Medication dosage is based on weight per kilogram (kg).
We need to convert the weight to kg for accurate calculation.
Conversion factor: 1 kg = 2.205 lbs
Client weight (kg) = 126 pounds / 2.205 lbs/kg
Client weight (kg) = 57.14 kg (round to nearest hundredth)
2. Epoetin alfa dosage:
Prescribed dose: 50 units/kg (given)
3. Epoetin alfa concentration:
Vial label: 10,000 Units/mL
4. We need to find the volume (mL) to administer that provides the prescribed dose (50 units/kg) based on the client's weight (57.14 kg) and the medication concentration (10,000 Units/mL).
Calculation:
Total epoetin alfa dose (units): Dose (units/kg) x Client weight (kg)
Total epoetin alfa dose (units): 50 units/kg * 57.14 kg
Total epoetin alfa dose (units): 2857 units (round to nearest whole number)
Volume to administer (mL): Total dose (units) / Concentration (units/mL)
Volume to administer (mL): 2857 units / 10,000 Units/mL
Volume to administer (mL): 0.2857 mL (round to nearest hundredth as requested)
Therefore, the nurse should administer approximately 0.29 mL of epoetin alfa subcutaneously.
