A healthcare professional is getting ready to give a patient voriconazole 6 mg/kg through an intermittent IV bolus. The patient weighs 127 lb. The voriconazole available is 5 mg/mL.

The patient weighs 100 lb.

The voriconazole available is 6 mg/mL.

The medication will be given orally.

The medication will be given through an intermittent IV bolus.

Answer and Explanation

The Correct Answer is D

Choice A rationale
This choice is incorrect because the patient weighs 127 lb, not 100 lb. The weight of the patient is important in calculating the correct dosage of medication.
Choice B rationale
This choice is incorrect because the available voriconazole is 5 mg/mL, not 6 mg/mL. The concentration of the medication is important in calculating the correct volume to administer.
Choice C rationale
This choice is incorrect because the medication will not be given orally. The route of administration is important in determining how the medication will be absorbed and distributed in the body.
Choice D rationale
This choice is correct because the medication will be given through an intermittent IV bolus. This route of administration allows the medication to be delivered directly into the bloodstream, providing a rapid onset of action.

Correct Answer is ["83"]

Explanation

Step 1: Convert 1g of cefazolin to mg. We know that 1g = 1000mg. So, 1g of cefazolin is 1000mg.

Step 2: Calculate the total volume of the solution. We have 1000mg of cefazolin in 250mL of 0.9% sodium chloride. So, the total volume of the solution is 250mL.

Step 3: Calculate the time for the infusion. We are told that the infusion should be over 30 minutes. So, the time for the infusion is 30 minutes.

Step 4: Calculate the drop factor. We are told that the drop factor on the manual IV tubing is 10 gtt/mL. So, the drop factor is 10 gtt/mL.

Step 5: Calculate the flow rate. The flow rate is calculated by dividing the total volume of the solution by the time for the infusion, and then multiplying by the drop factor. So, the flow rate is (250mL ÷ 30min) × 10 gtt/mL.

Step 6: Round the answer to the nearest whole number. The calculated flow rate is 83.33 gtt/min. When rounded to the nearest whole number, the flow rate is 83 gtt/min.

Correct Answer is ["31"]

Explanation

Step 1: Calculate the total volume of the IV solution. The doctor ordered 1,000 mL.

Step 2: Calculate the total time for the infusion. The doctor ordered the infusion to run over 8 hours. So, 8 hours × 60 min/hour = 480 min.

Step 3: Calculate the IV flow rate in mL/min. So, 1,000 mL ÷ 480 min = 2.083 mL/min. Step 4: Calculate the IV flow rate in gtt/min. The tubing has a drop factor of 15 gtt/mL. So,

2.083 mL/min × 15 gtt/mL = 31.25 gtt/min. The nurse should set the IV flow rate to deliver 31

gtt/min.
