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 ["0.4"]
Explanation
The prescribed dosage of enoxaparin is 40 mg. The available medication is in a concentration of 100 mg/mL. So, the volume to administer is 40 mg ÷ 100 mg/mL = 0.4 mL. Rounding to the nearest tenth, the nurse should administer 0.4 mL.
So, the correct answer is 0.4 mL.
Correct Answer is ["2.1"]
Explanation
First, we need to calculate the total daily dose of tobramycin for the client. The total daily dose is calculated as follows:
Total daily dose = Dose per kg per day x Weight Total daily dose = 3 mg/kg/day x 85 kg Total daily dose = 255 mg/day
Since the total daily dose is divided into three doses, each dose will be:
Each dose = Total daily dose / Number of doses Each dose = 255 mg / 3 Each dose = 85 mg
Now, we need to convert this dose into mL. We know that we have tobramycin 40 mg/mL, so:
Volume to administer = Each dose / Concentration Volume to administer = 85 mg / 40 mg/mL Volume to administer = 2.125 mL
Rounding this to the nearest tenth, we get 2.1 mL.
