Final answer:
To calculate the infusion rate in mL/hr for a patient to receive 1.3 L of NS over 4 hours, convert liters to milliliters and divide by the time in hours, resulting in a rate of 325 mL/hr.
Step-by-step explanation:
The subject in question relates to calculating the infusion rate of a saline solution as part of a patient's health care. The scenario presented involves a patient who is to receive 1.3 liters of Normal Saline (NS) over a span of 4 hours. To determine the infusion rate in milliliters per hour (mL/hr), a straightforward conversion must be performed. Since 1 liter is equivalent to 1000 milliliters, 1.3 liters is the same as 1300 milliliters. To calculate the rate, divide the total volume (1300 mL) by the time in hours (4 hours), which gives us an infusion rate of 325 mL/hr.
