Question

a nurse is preparing to administer dextrose 5% in water (d₅w) 250 ml iv to infuse over 4 hr. the drop factor of the manual iv tubing is 60 gtt/ml. the nurse should set the manual iv infusion 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.)

Explanation:

Step1: Convert infusion time to minutes

Since \(1\) hour has \(60\) minutes, for \(4\) hours, the time in minutes is \(t = 4\times60=240\) minutes.

Step2: Use the formula for IV flow rate (gtt/min)

The formula for calculating the IV flow rate (in gtt/min) is \(\text{Flow rate (gtt/min)}=\frac{\text{Volume (mL)}\times\text{Drip factor (gtt/mL)}}{\text{Time (min)}}\).
We are given that the volume \(V = 250\) mL, the drip factor \(gtt/mL=60\) gtt/mL, and the time \(t = 240\) minutes.
Substitute the values into the formula: \(\text{Flow rate}=\frac{250\times60}{240}\).
First, calculate \(250\times60 = 15000\). Then, \(\frac{15000}{240}=\frac{15000\div60}{240\div60}=\frac{250}{4}=62.5\).

Answer:

\(63\)
