A practical nurse (PN) is caring for a client who is receiving a continuous intravenous (IV) infusion of Lactated Ringer's for fluid replacement. The healthcare provider's prescription is for to infuse over 12 hours. The primary IV tubing has a drop factor of . The registered nurse (RN) has initiated the infusion. At what rate, in drops per minute (gtt/min), should the PN verify the IV is infusing?

Cevap: 21 gtt/min
Cevap
21
To calculate the gravity flow rate in drops per minute, the nurse must first convert the total infusion time into minutes (12 hours * 60 = 720 minutes). Then, use the standard formula: (Total Volume / Total Time in minutes) * Drop Factor. Plugging in the values gives: (1,000 mL / 720 minutes) * 15 gtt/mL = 20.833 gtt/min. Because the nurse cannot administer a fraction of a drop, the final step is to round to the nearest whole number, which is 21.
