A nurse is preparing to administer potassium chloride 40 mEq in dextrose 5% in 0.9% sodium chloride 1,000 mL IV to infuse over 8 hr. The tubing has a drop factor of 15 gtt/mL.
The nurse should set the IV flow rate to deliver how many gtt/min?
(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 ["31"]
To calculate the IV flow rate in drops per minute (gtt/min), we can use the following steps:
Calculate the total number of minutes for the infusion:
8 hours × 60 minutes/hour = 480 minutes
Determine the total number of drops needed for the infusion:
The total volume to be infused is 1000 mL.
The drop factor is 15 gtt/mL.
1000 mL × 15 gtt/mL = 15000 gtt
Calculate the IV flow rate in drops per minute:
15000 gtt ÷ 480 min ≈ 31 gtt/min
Rounding to the nearest whole number, the nurse should set the IV flow rate to deliver 31 gtt/min.

Correct Answer is ["0.7"]
Explanation
To calculate the amount of epoetin to administer, we can use the following formula:
Amount to administer (mL) = (Desired dose (units) / Available dose (units/mL))
Plugging in the given values:
Amount to administer (mL) = (7,000 units / 10,000 units/mL)
Now, let's solve for the amount to administer:
Amount to administer (mL) = (7,000 / 10,000) = 0.7 mL
So, the nurse should administer 0.7 mL of epoetin subcutaneously for the management of anemia related to chronic kidney disease.
Correct Answer is ["69"]
Explanation
To calculate the amount of voriconazole to be administered, we can follow these steps:
Convert the client's weight from pounds to kilograms.
Calculate the total amount of voriconazole needed based on the client's weight.
Determine the volume of the medication to be administered based on the concentration of the available solution.
Let's proceed with the calculations:
Converting the client's weight from pounds to kilograms:
Client's weight = 127 lb
1 lb ≈ 0.453592 kg
Client's weight ≈ 127 lb 0.453592 kg/lb ≈ 57.61 kg
Calculating the total amount of voriconazole needed:
Voriconazole dose = 6 mg/kg 57.61 kg ≈ 345.66 mg
Determining the volume of the medication to be administered:
Available voriconazole concentration = 5 mg/mL
Volume to be administered = 345.66 mg / 5 mg/mL ≈ 69.132 mL
Rounding to the nearest whole number, the nurse should administer 69 mL of voriconazole.
