Heparin therapy is usually considered therapeutic when the patient’s activated partial thromboplasin time (aPTT) is how many times normal?
a) 1.5 to 2
The amount of heparin administered is based on aPTT results, which should be obtained in follow-up to any alteration of dosage.
b) .5 to 1
The patient’s aPTT value would have to be greater than .5 to 1 times normal to be considered therapeutic.
c) 2.5 to 3
An aPTT value that is 2.5 to 3 times normal would be too high to be considered therapeutic.
d) .25 to .75
The patient’s aPTT value would have to be greater than .25 to .75 times normal to be considered therapeutic.
