Question

a nurse is preparing to administer dextrose 5% in 0.45% sodium chloride 1l to infuse at 100 ml/hr. the nurse is using microtubing. the nurse should set the manual iv infusion to deliver how many gtt/min? (round to the nearest whole number.)

Explanation:

Step1: Recall the formula

The formula for calculating the infusion rate (gtt/min) is \( \text{Infusion rate (gtt/min)}=\frac{\text{Volume (mL)}×\text{Drip factor (gtt/mL)}}{\text{Time (min)}} \). For microtubing, the drip factor is 60 gtt/mL.

Step2: Convert the time unit

The volume is \( V = 100\space mL \) (since the infusion rate is 100 mL per hour). The time \( t=1\space h=60\space min \).

Step3: Substitute values into the formula

Substitute \( V = 100\space mL \), \( \text{Drip factor}=60\space gtt/mL \), and \( t = 60\space min \) into the formula: \( \text{Infusion rate (gtt/min)}=\frac{100\times60}{60} \).

Step4: Calculate the result

\(\frac{100\times60}{60}=100\space gtt/min\) (the 60s in the numerator and denominator cancel out).

Answer:

100 gtt/min
