Question

a nurse is preparing to administer 0.9% sodium chloride 1 l iv to infuse over 8 hr. the drop factor of the manual iv tubing set is 15 gtts/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.) gtts/min

Explanation:

Step1: Convert volume to mL

$1\ \text{L} = 1000\ \text{mL}$

Step2: Convert time to minutes

$8\ \text{hr} \times 60 = 480\ \text{min}$

Step3: Calculate infusion rate

$\text{Infusion rate (gtt/min)} = \frac{\text{Total volume (mL)} \times \text{Drop factor (gtt/mL)}}{\text{Total time (min)}}$
$\text{Infusion rate} = \frac{1000 \times 15}{480}$

Step4: Compute and round result

$\frac{15000}{480} = 31.25 \approx 31$

Answer:

31 gtts/min
