Question

Nurse is preparing to administer NS 1L over 8 hr to a patient. Drop factor of manual IV tubing is 15 gtt/mL. Nurse should set manual IV infusion to deliver how many gtt/min?

A) 60 gtt/min
B) 120 gtt/min
C) 30 gtt/min
D) 15 gtt/min

Answer 1

The nurse should set the manual IV infusion to deliver approximately 31.25 gtt/min.

Step-by-step explanation:

First, we need to convert the 1L of NS (normal saline) to mL, which is 1000 mL. Since we want to administer the fluid over 8 hours, we need to find the drop rate per minute. To do this, we can use the formula:

Drop Rate = Volume (mL) × Drop Factor ÷ Time (minutes)

Plugging in the values: Drop Rate = 1000 mL × 15 gtt/mL ÷ 480 min = 31.25 gtt/min.

So, the nurse should set the manual IV infusion to deliver approximately 31.25 gtt/min.
