Question

The PN starts his shift at 1900h. At report, he hears that his patient has 800 mL TBI at 150 mL/h.

What time should the PN hang a new bag of fluid?

Answer 1

The PN should hang a new bag of fluid at approximately 12:20 AM, 5.33 hours after starting their shift at 19:00 (7:00 PM).

Step-by-step explanation:

The student has a patient with 800 mL of total body irrigation (TBI) fluid to be infused at a rate of 150 mL/h. To calculate when the PN should hang a new bag of fluid, we divide the total volume of fluid by the hourly infusion rate:

Total volume (mL) ÷ Infusion rate (mL/h) = Time until new bag needed (hours)
800 mL ÷ 150 mL/h = 5.33 hours

Since the PN starts their shift at 19:00 (7:00 PM), we simply add the 5.33 hours to the start time:
19:00 + 5 hours and 20 minutes (0.33 of an hour is approximately 20 minutes) = 00:20 (12:20 AM)

Therefore, the PN should hang a new bag of fluid at approximately 00:20, or 12:20 AM, after their shift starts.
