Final answer:
The patient is receiving 2,083,333 units/hr of Heparin.
Step-by-step explanation:
To calculate the rate at which the patient is receiving Heparin, we can use the formula:
Rate = (Amount of Heparin) / (Time)
In this case, the client is receiving 25,000 units of Heparin in 500 mL of solution. We need to convert the volume from mL to L to match the units of the rate. There are 1000 mL in 1 L, so the volume is 0.5 L. The time is given as 12 mL/hr, so we need to convert to L/hr by dividing by 1000. Therefore, the time is 0.012 L/hr.
Substituting the values into the formula, we get:
Rate = (25,000 units) / (0.012 L/hr) = 2,083,333 units/hr
