What is the appropriate action for a licensed practical nurse (LPN) who notes that the activated partial thromboplastin time (aPTT) level of a client receiving heparin sodium via continuous intravenous infusion for deep vein thrombosis is 90 seconds when it was 30 seconds before therapy was initiated?


The LPN should promptly inform the RN about the aPTT level.

When the aPTT is too high, it indicates that there may be an increased risk of bleeding. Therefore, the RN should be informed so that they can evaluate whether to adjust the dosage of heparin sodium or to take other appropriate measures to prevent the risk of bleeding. It is also helpful to monitor the client for any signs of bleeding.
