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 ["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

Correct Answer is ["50"]

Explanation

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

1. Calculate the total infusion time in minutes:
8 hours x 60 minutes/hour = 480 minutes

2. Calculate the drops per minute:
Total volume (mL) x Drop factor (gtt/mL) / Infusion time (minutes) = Drops per minute (gtt/min)
400 mL x 60 gtt/mL / 480 minutes = 50 gtt/min
