When to withhold Heparin? - The expected value for aPTT is 40 seconds. A therapeutic level of heparin increases the aPTT by a factor of 1.5 to 2, making the aPTT 60 to 80 seconds. An aPTT level of 98 is above the expected reference range, indicating that the dosage should be reduced or the infusion withheld until the aPTT returns to the therapeutic range. What does Valproic Acid treat? - Valproic acid is used to treat certain types of seizures (epilepsy). This medicine is an anticonvulsant that works in the brain tissue to stop seizures. Valproic acid is also used to treat the manic phase of bipolar disorder (manicdepressive illness), and helps prevent migraine headaches.

Which of the following laboratory tests should the nurse review prior to adjusting the client's heparin? - aPTT Prior to adjusting the client's continuous heparin infusion, the nurse should review the client's activated partial thromboplastin time (aPTT). The expected reference range for the aPTT is 40 seconds. Clients who are receiving continuous heparin therapy should have an aPTT of 60 to 80 seconds, which is 1.5 to 2 times of the expected aPTT level. The nurse should increase or decrease the heparin infusion according to this value.
