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 ["8"]
Explanation
Step 1 is to convert the client’s weight from pounds to kilograms since the dosage is ordered in units/kg. There are approximately 2.2 lb/kg, so 130 lb ÷ 2.2 lb/kg = 59.1 kg. The doctor ordered calcitonin at a dosage of & units/kg, so we multiply the client’s weight in kg by the dosage: 59.1 kg × & units/kg = & units. The medication is available at a concentration of 200 units/mL, so we divide the total units needed by the units per mL: & units ÷ 200 units/mL = & mL.
So, the correct answer is 8mL.
Correct Answer is ["9.4"]
Explanation
Step 1 is to calculate the dose to be administered which is 300 mg. Step 2 is to calculate the concentration of the available medication which is 160 mg/5 mL. Step 3 is to calculate the volume to be administered as (300 mg ÷ (160 mg/5mL)) = 9.375 mL.
So, the correct answer is, after analyzing all steps, the nurse should administer 9.4 mL per dose (rounded to the nearest tenth).
