Question

a nurse is preparing to administer 0.45% sodium chloride (0.45% nacl) 750 ml iv to infuse over 10 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 hours to minutes

Since there are 60 minutes in an hour, for 10 hours, the number of minutes is \(10\times60 = 600\) minutes.

Step2: Use the formula for IV flow rate

The formula for the IV flow rate (in gtt/min) is \(\text{Flow rate}=\frac{\text{Volume}(mL)\times\text{Drip factor}(gtt/mL)}{\text{Time}(min)}\).
We have Volume \(V = 750\) mL, Drip factor \(D = 60\) gtt/mL, and Time \(T=600\) min.
Substitute the values into the formula: \(\text{Flow rate}=\frac{750\times60}{600}\).
First, calculate \(750\times60 = 45000\).
Then, \(\frac{45000}{600}=75\).

Answer:

75
