A nurse is preparing to administer cefazolin 1g intermittent IV bolus in 0.9% sodium chloride 250 mL over 30 min.
The drop factor on the manual IV tubing is 10 gtt/mL. The nurse should set the manual 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.). gtt/min.
The Correct Answer is ["83"]
Step 1 is to calculate the total volume to be infused in mL/min. This is done by dividing the total volume (250 mL) by the time in minutes (30 min). So, 250 mL ÷ 30 min = 8.33 mL/min. Step 2 is to convert mL/min to gtt/min using the drop factor. So, (8.33 mL/min) × (10 gtt/mL) = 83.3 gtt/min. Round off to the nearest whole number, the correct answer is 83 gtt/min.

Correct Answer is ["5"]
Explanation
Step 1 is to calculate the total daily dose. The total daily dose is 150 mg. Step 2 is to divide the total daily dose by the number of doses. The number of doses is 3. So, the calculation is 150 mg ÷ 3 = 50 mg/dose. Step 3 is to calculate the volume to administer using the available medication concentration. The available medication concentration is 50 mg/5 mL. So, the calculation is 50 mg ÷ (50 mg/5 mL) = 5 mL.
So, the correct answer is 5 mL, after rounding to the nearest whole number.
Correct Answer is ["0.04"]
Explanation
Step 1 is to determine the amount of medication in 1 mL. This is calculated by dividing the total available medication (250 mcg) by the total volume (1 mL):
250 mcg ÷ 1 mL = 250 mcg/mL
Step 2 is to determine how many mL are needed to obtain 10 mcg. This is done by dividing the required dose (10 mcg) by the concentration (250 mcg/mL):
10 mcg ÷ 250 mcg/mL = 0.04 mL
Thus, the correct amount to administer is 0.04 mL.
