Pt inr normal range on coumadin9/23/2023 ![]() Please do not copy this quiz directly however, please feel free to share a link to this page with students, friends, and others.The PT/INR is a helpful test for assessing the coagulation process. Please refer to the latest NCLEX review books for the latest updates in nursing. ![]() *Disclaimer: While we do our best to provide students with accurate and in-depth study quizzes, this quiz/test is for educational and entertainment purposes only. You can also take more fun nursing quizzes. The answer is C: Normal…an approximate normal range for an aPTT is about 30-40 seconds.ĭon’t forget to tell your friends about this quiz by sharing it your Facebook, Twitter, and other social media. Too high, the patient is at risk for bleeding. The nurse would interpret this lab result as?Ī. All of these could increase the PT level (a normal range is approximately 10-12 seconds).ġ0. What conditions below could cause this result? Select all that apply: Fibrin is one of the main ingredients for clot formation.ĩ. When thrombin is on board it is responsible for turning fibrinogen to fibrin. The answer is C: Thrombin….Prothrombin turns into thrombin by clotting factor V. Fill in the blank: Prothrombin turns into _ with the assistance of clotting factor V. Therefore, the patient’s medication is not effective at this time for preventing blood clots.Ĩ. A therapeutic INR for a patient taking Warfarin should be 2-3. The patient is experiencing Warfarin toxicity. The medication is not effective at preventing blood clots.ĭ. Your patient, who is prescribed Warfarin for blood clots, has an INR of 1. The answer is A: 10-12 seconds (varies among labs).ħ. What is an approximate normal range for a PT (prothrombin) level? It may be slightly higher if a patient is at a high risk for clot formation….(ex: up to 4.5)Ħ. What is the therapeutic INR range for this medication to be effective? A patient is prescribed Warfarin (Coumadin) for the treatment of a blood clot. If the aPTT is too high, bleeding can occur.ĥ. If the aPTT is too low, blood clots can form. An aPTT should be 1.5-2.5 times the normal value range for Heparin to achieve a therapeutic effect in a patient to prevent blood clots. In order for this medication to have a therapeutic effect on the patient, the aPTT should be? A patient is receiving continuous IV Heparin. The answer is B: 30-40 seconds (This range varies among labs).Ĥ. What is the approximate normal range for an aPTT result? The aPTT is an important result used to assess the effectiveness of Heparin (NOT Warfarin), and it’s measured in SECONDS (not milliseconds).ģ. The intrinsic pathway is activated when there is inside injury within the vascular system. Therefore, clotting factors I, II, V, X (which are part of common pathways) and clotting factors XII, XI, IX, VIII (which are part of intrinsic pathway) are assessed. The aPTT assesses the intrinsic pathway of coagulation and common pathways. The answer is B: The aPTT assess the intrinsic pathway of coagulation and common pathways. The aPTT only assesses clotting factor VII. The aPTT assesses the intrinsic pathway of coagulation and common pathways.ĭ. The aPTT is an important result used to assess the effectiveness of Warfarin.ī. Which statement is TRUE about this coagulation test?Ī. Your patient is being evaluated for a bleeding disorder. The extrinsic pathway is activated when there is outside/external injury that results in blood loss from the vascular system.Ģ. The PT/INR assesses the extrinsic pathway of coagulation (which uses clotting factor VII) and common pathways (which uses factor I, II, V, X). The answer is A: Extrinsic pathway of coagulation and common pathways. Intrinsic pathway of coagulation and common pathways Extrinsic pathway of coagulation and common pathwaysī. As the nurse you know that this blood test assesses?Ī. A patient is ordered a PT/INR blood test. (NOTE: When you hit submit, it will refresh this same page. ![]()
