Find the flow rate in gtt/min.

Ordered: 1,800 mL RL q24h using tubing calibrated to 10 gtt/mL
Answer and Explanation

The Correct Answer is ["13"]

Total volume = 1,800 mL

Infusion time = 24 hours

Drop factor = 10 gtt/mL

  • Convert the infusion time from hours to minutes.

Infusion time in minutes = 24 hours × 60 minutes/hour

 = 1440 minutes.

  • Calculate the flow rate in drops per minute (gtt/min) using the formula:

Flow rate (gtt/min) = (Total volume (mL) × Drop factor (gtt/mL)) / Infusion time (min)

      = (1800 mL × 10 gtt/mL) / 1440 min

      = 18000 / 1440

      = 12.5 gtt/min.

  • Round the answer to the nearest whole number.

= 13 gtt/min.

Correct Answer is ["120"]

Explanation

Given values:

Flow rate = 20 gtt/min

Infusion time = 6 hours

Drop factor = 60 gtt/mL

  • Convert the infusion time from hours to minutes.

Infusion time in minutes = 6 hours × 60 minutes/hour

= 360 minutes.

  • Calculate the total volume in milliliters (mL) using the formula:

Total Volume (mL) = (Flow rate (gtt/min) × Infusion time (min)) / Drop factor (gtt/mL)

= (20 gtt/min × 360 min) / 60 gtt/mL

= 7200 / 60

= 120 mL.

Correct Answer is C

Explanation

Calculation:

D10W stands for Dextrose 10% in Water.2 This means the solution contains 10 grams of dextrose for every 100 mL of solution.

  • Calculate the total grams of dextrose in 1,000 mL.

Using a ratio:

10g/100mL ​=x/1000mL. ​

To solve for x:

x= (10g×1000mL​)/ 100mL

=10g×10

=100grams
