Question

a nurse is preparing to administer 0.9% sodium chloride (0.9% nacl) 500 ml iv to infuse over 2 hr. the drop factor of the manual iv tubing is 10 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.) gtt/min

Explanation:

Step1: Convert hours to minutes

Since there are 60 minutes in an hour, for 2 hours, the number of minutes is \(2\times60 = 120\) minutes.

Step2: Use the formula for calculating the infusion rate (gtt/min)

The formula for the manual IV infusion rate (gtt/min) is \(\text{Infusion rate}=\frac{\text{Volume}(mL)\times\text{Drip factor}(gtt/mL)}{\text{Time}(min)}\).
Here, the volume \(V = 500\) mL, the drip factor \(gtt/mL=10\) gtt/mL, and the time \(t = 120\) min.
Substitute the values into the formula: \(\frac{500\times10}{120}=\frac{5000}{120}\approx41.67\)

Answer:

42
