Final answer:
The patient will receive fluid 6 times before the doctor checks on him.
Step-by-step explanation:
To find out how many times the patient will receive fluid before the doctor checks on him, we need to divide the total amount of fluids given by the amount given in each interval.
The nurse provides 0.25 liters of fluid every 4 hours, which is 250 milliliters.
We are given that the doctor wants to stop the fluid intake after 1,500 milliliters. So, we divide 1,500 by 250 to get the number of times the patient will receive fluid.
1,500 mL / 250 mL = 6
Therefore, the patient will receive fluid 6 times before the doctor checks on him.
