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 ["0.71"]
Explanation
Step 1 is to calculate the amount of medication per mL. This is done by dividing the total amount of medication (250 mg) by the concentration (350 mg/mL). So, 250 mg ÷ 350 mg/mL = 0.71 mL.
Correct Answer is ["0.8"]
Explanation
Step 1 is to convert the client’s weight from pounds to kilograms. Given that 1 kg = 2.2 lb, we calculate:
183 lb ÷ 2.2 = 83.18 kg
Rounding to the nearest hundredth, the client’s weight is 83.18 kg.
Step 2 is to calculate the total amount of medication needed. The prescribed dosage is 0.1 mg/kg, so we calculate:
0.1 mg/kg × 83.18 kg = 8.32 mg
Rounding to the nearest hundredth, the total medication required is 8.32 mg.
Step 3 is to determine the volume to administer. The available concentration of furosemide is 10 mg/mL, so we divide:
8.32 mg ÷ 10 mg/mL = 0.832 mL
Rounding to the nearest tenth, the correct amount to administer is 0.8 mL.
