Answer:
According to the order, to administer 5 U/hr of the Heparin solution, 0.125 ml/hr should be administered.
Step-by-step explanation:
Heparin is an anticoagulant that is administered parenterally, subcutaneously or intravenously.
If 20000 U are diluted in a 500 ml solution, to pass 5 U/hr to the patient, it must be established how many milliliters must be passed in 1 hour.
Knowing that the concentration of Heparin in the sodium chloride solution is 20000 in 500 ml, which is equivalent to 40 U/ml, the calculation is made:
40 U ------------ 1 ml
5 OR ------------ X
X = (5 X 1)/ 40
X = 0.125 ml /hr
In the infusion pump, the amount of Heparin solution to be passed in 1 hour is 0.125 ml.
