A nurse is preparing to administer digoxin 750 mcg IV bolus.
How many mg should the nurse administer? (Round the answer to the nearest hundredth.
Use a leading zero if it applies.
Do not use a trailing zero.). mg.
The Correct Answer is ["0.75"]
Step 1 is to convert mcg to mg. This is done by dividing the total amount of medication (750 mcg) by 1000 (since 1 mg = 1000 mcg). So, 750 mcg ÷ 1000 = 0.75 mg.

Correct Answer is ["33"]
Explanation
Step 1: Calculate the total volume to be administered. The total volume is the volume of the drug (ceftriaxone 1 g) which is in 0.9% sodium chloride 100 mL. So, the total volume is 100 mL.
Step 2: Calculate the total time for the drug to be administered. The drug is to be administered over 45 minutes.
Step 3: Calculate the flow rate in mL/min. The flow rate is the total volume divided by the total time. So, the flow rate is (100 mL ÷ 45 min) = 2.22 mL/min.
Step 4: Calculate the flow rate in gtt/min. The flow rate in gtt/min is the flow rate in mL/min multiplied by the drop factor. The drop factor is 15 gtt/mL. So, the flow rate in gtt/min is (2.22 mL/min × 15 gtt/mL) = 33.33 gtt/min.
Step 5: Round the answer to the nearest whole number. The flow rate in gtt/min rounded to the nearest whole number is 33 gtt/min.
So, the nurse should set the IV flow rate to deliver 33 gtt/min.
