Question

At the beginning of the shift at 7:00 am, a client has 650 ml of normal saline solution left in the intravenous bag, which is infusing at 125 ml/hr. at 9:30 am the healthcare provider changes the iv solution to lactated ringer solution, which is to infuse at 100 ml/hr. what total amount of intravenous solution should the client have received by the end of the 8-hour shift? record your answer using a whole number.

Answer 1

The 8 hour shift is from 7.00 am to 3.00 pm.
At the beginning, from 7.00 am to 9.30am (2.5 hrs.), the client has normal saline which is infusing at 125 ml/hr.
Hence amount of normal saline which was injected= 2.5 hrs. x 125 ml/hr.
                                                                                 = 312.5 ml
from 9.30am to 3.00 pm (5.5 hrs) lactated ringer solution, which is to infuse at 100 ml/hr was given. 
Hence amount of lactated ringer solution given = 5.5 hrs x 100 ml/hr
                                                                           = 550 ml
Total amount of IV solution given = normal saline + lactated ringer solution
                                                     = 312.5 ml + 550 ml
                                                     = 862.5 ml
                                                     = 863 ml
