PT and INR are used to measure clotting times in patients who are taking Warfarin (Coumadin). It is important that the nurse collect an aPTT in 6 hours (some protocols may say 4 hours) after starting the drip. An activated partial thromboplastin time (aPTT) is used to measure clotting time in patients who are on Heparin. Collect an aPTT level in 6 hours per protocol. Collect a Troponin level in 6 hours per protocol.ĭ. Collect an INR level in 4 hours per protocol.Ĭ. Collect a PT level in 6 hours per protocol.ī. What will be your next important nursing action?Ī. You administer a bolus of Heparin and start the drip per protocol as ordered by the physician. Your patient is started on a Heparin drip.
