A nurse is preparing to administer dextrose 5% in lactated Ringer's 2 L IV to infuse over 12 hr. The drop factor on the manual IV tubing is 20 gtt/mL. The nurse should set the 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 ["56"]
Step 1 is to calculate the total volume to be infused in minutes. This is done by multiplying the total volume (2000 mL) by the drop factor (20 gtt/mL), and then dividing by the total time (12 hr × 60 min/hr). So, (2000 mL × 20 gtt/mL) ÷ (12 hr × 60 min/hr) = 55.56 gtt/min, which rounds to 56 gtt/min.

Correct Answer is ["48"]
Explanation
Step 1 is to convert the client’s weight from pounds to kilograms since the medication dosage is prescribed in mg/kg. Given that 1 kg is approximately 2.2 lb, the conversion is:
210 lb ÷ 2.2 = 95.45 kg (rounded to the nearest hundredth).
Step 2 is to calculate the total amount of medication needed using the formula:
Dose (mg/kg) × Weight (kg) = Total medication needed (mg)
5 mg/kg × 95.45 kg = 477.27 mg (rounded to the nearest hundredth).
Step 3 is to calculate the volume to administer using the formula:
Total medication needed (mg) ÷ Concentration (mg/mL) = Volume to administer (mL)
477.27 mg ÷ 10 mg/mL = 47.73 mL
Rounding off to the nearest whole number, the nurse should administer 48 mL of gentamicin.
