Question

question 2 of 5, step 4 of 6
8/30
correct
order: lactated ringer’s 1,000 ml iv for 9.6 h at 125 ml/h
drop factor: 10 gtt/ml
step 4 of 6: recalculate flow rate (the adjusted) in gtt/min.
answer
gtt/min

Explanation:

Step1: Convert mL/h to mL/min

We know 1 hour = 60 minutes. So, if the rate is 125 mL/h, then to convert to mL/min, we divide by 60. The formula is $\text{mL/min}=\frac{125}{60}$.

Step2: Calculate drops - per - minute

The drop factor is 10 gtt/mL. The formula for flow rate in gtt/min is $\text{Flow rate (gtt/min)}=\text{Drop factor (gtt/mL)}\times\text{Flow rate (mL/min)}$. Substituting the values, we get $\text{Flow rate (gtt/min)} = 10\times\frac{125}{60}=\frac{1250}{60}=\frac{125}{6}\approx20.83$. Rounding to the nearest whole number, we get 21 gtt/min.

Answer:

21 gtt/min
