A nurse is preparing to administer dextrose 5% in water (DSW) 200 mL IV to infuse over 24 hr. The drop factor of the manual IV tubing is 15 gtt/mL. The nurse should set the manual IV infusion to deliver how many gtt/min? (Round to the nearest whole number. Use a leading zero if it applies. Do not use a trailing zero.)
Answer and Explanation

The Correct Answer is ["2"]

Let's calculate the IV flow rate step-by-step:

1. Calculate the total infusion time in minutes:
24 hours x 60 minutes/hour = 1440 minutes

2. Calculate the drops per minute:
Total volume (mL) x Drop factor (gtt/mL) / Infusion time (minutes) = Drops per minute (gtt/min)
200 mL x 15 gtt/mL / 1440 minutes = 2.083 gtt/min

3. Round to the nearest whole number:
2.083 gtt/min ≈ 2 gtt/min

Correct Answer is ["25"]

Explanation

Here's the step-by-step calculation:

Given information:
Infusion volume: 100 mL
Infusion time: 1 hour (60 minutes)
Drop factor: 15 gtt/mL

Calculate the infusion rate in mL/min:
Divide the infusion volume by the infusion time: 100 mL / 60 min = 1.67 mL/min (rounded to two decimal places).

Calculate the number of drops per minute:
Multiply the infusion rate by the drop factor: 1.67 mL/min x 15 gtt/mL = 25.05 gtt/min.

Round off:
Rounding to the nearest whole number, we get 25 gtt/min.

Correct Answer is ["10"]

Explanation

Here's the step-by-step calculation:

Given information:
Desired dose: 50 mg
Available concentration: 25 mg/5 mL

Calculate the volume needed:
Set up a proportion:
Desired dose / Available concentration = Volume needed / 5 mL
50 mg / 25 mg/5 mL = Volume needed / 5 mL

Solve for Volume needed:
Volume needed = 50 mg x 5 mL / 25 mg
Volume needed = 10 mL
