A nurse is preparing to administer 0.9% sodium chloride 5 L IV to infuse over 6 hr. 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 ["250"]
Calculation:
Convert the total volume to milliliters:
Total volume: 1.5 L
Conversion: 1.5 L × 1000 mL/L = 1500 mL
Determine the total infusion time in hours:
Infusion time: 6 hours
Calculate the IV pump flow rate in mL/hr:
Formula: Flow rate (mL/hr) = Total volume (mL) / Total time (hours)
= 1500 mL / 6 hours
= 250 mL/hr

Correct Answer is ["2.5"]
Explanation
Calculation:
Ordered dose: 5 mg
Available strength: 2 mg per tablet
Calculate the number of tablets needed:
Formula: Number of tablets = Desired dose / Available dose per tablet
= 5 mg / 2 mg/tablet
= 2.5 tablets
Correct Answer is ["285"]
Explanation
Calculation:
Convert the client's weight from pounds (lbs) to kilograms (kg):
Formula: Weight in kg = Weight in lbs / 2.2 lbs/kg
= 167 lbs / 2.2 lbs/kg
≈ 75.91 kg
Calculate the total dose of amphotericin B lipid complex needed:
Ordered dose: 3.75 mg/kg
Client's weight in kg: ≈ 75.91 kg
Formula: Total dose (mg) = Ordered dose (mg/kg) × Client's weight (kg)
= 3.75 mg/kg × 75.91 kg
≈ 284.66 mg
Determine the concentration of the available amphotericin B lipid complex solution:
Available amount: 300 mg
Volume of solution: 300 mL
Formula: Concentration (mg/mL) = Total amount (mg) / Total volume (mL)
= 300 mg / 300 mL
= 1 mg/mL
Calculate the volume of solution to administer:
Formula: Volume to administer (mL) = Desired dose (mg) / Concentration (mg/mL)
= 284.66 mg / 1 mg/mL
= 284.66 mL
Round the answer to the nearest whole number:
284.66 mL rounded to the nearest whole number is 285 mL.
