Question

A nurse is preparing to administer 5% dextrose in water (D5W) 400ml IV to infuse over 1 hour. The drop factor of the manual IV tubing is 15 gtt/ml. The nurse should set the manual IV infusion to deliver how many gtt/min? (round whole number)

a) 100 gtt/min
b) 67 gtt/min
c) 50 gtt/min
d) 33 gtt/min

Answer 1

To calculate the drip rate for the manual IV infusion, you can use the formula:

\[ \text{Drip Rate (gtt/min)} = \frac{\text{Volume (ml)}}{\text{Time (min)}} \times \text{Drop Factor (gtt/ml)} \]

In this case:

\[ \text{Drip Rate} = \frac{400 \, \text{ml}}{60 \, \text{min}} \times 15 \, \text{gtt/ml} \]

Now, calculate the result to find the drip rate. The closest option is:

b) 67 gtt/min

Answer 2

The nurse should set the manual IV infusion to deliver 100 gtt/min.

Step-by-step explanation:

To calculate the drop rate, we can use the following formula:

Drop Rate (gtt/min) = Volume (ml) x Drop Factor (gtt/ml) / Time (min)

Given:
Volume = 400ml
Drop Factor = 15 gtt/ml
Time = 60 min

Substituting the values into the formula:

Drop Rate (gtt/min) = 400ml x 15 gtt/ml / 60 min = 100 gtt/min

Therefore, the nurse should set the manual IV infusion to deliver 100 gtt/min.
