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.

Answer and Explanation

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 ["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.

Correct Answer is ["1.5"]

Explanation

Step 1 is to determine the amount of medication needed. The order is for 30 mg and the available medication is 20 mg/mL.

So, we calculate 30 mg ÷ 20 mg/mL = 1.5 mL. Rounded to the nearest tenth, this is 1.5 mL.

So the correct answer is 1.5 mL.
