For each finding or intervention, select the best classification. | | Major-bleeding cue | Appropriate urgent response | Unsafe or delays care | | --- | --- | --- | --- | | New severe headache and confusion after a head impact while taking warfarin | | | | | Melena with hypotension and a hemoglobin decrease of 2.4 g/dL | | | | | Hold warfarin, activate urgent evaluation, assess the bleeding source, and obtain ordered CBC, INR, type and screen, and imaging | | | | | Prepare prescribed IV vitamin K and four-factor PCC for life-threatening or major bleeding | | | | | Administer the next warfarin dose because interruption always causes immediate thrombosis | | | | | Wait for the routine INR appointment despite worsening neurologic and hemodynamic findings | | | | ## Explanation New neurologic symptoms after head trauma and melena with hypotension and a substantial hemoglobin decrease are major-bleeding cues. Hold warfarin, activate urgent evaluation, obtain the ordered CBC, INR, type and screen, and imaging, and control the bleeding source. For life-threatening or major warfarin bleeding, prepare prescribed IV vitamin K and four-factor PCC; do not give the next dose or wait for a routine follow-up INR. ## In-depth explanation Quick answer Treat new neurologic symptoms after head trauma and hemodynamically significant gastrointestinal bleeding as major warfarin-associated bleeding. Hold warfarin, escalate urgently, evaluate the source, and prepare prescribed reversal. Why this is correct Warfarin can cause major or fatal hemorrhage. Critical-site symptoms, hypotension, and a hemoglobin decrease of at least 2 g/dL meet major-bleeding criteria and require interruption of anticoagulation and active hemostatic management. Easy analogy or mental picture Warfarin lowers the clotting barrier. When bleeding becomes critical, stop the leak and rebuild the clotting factors while treating the source. Memory hook Head symptoms, shock, or major hemoglobin drop: hold, escalate, reverse. NCLEX decision rule Do not classify severity from the INR alone. Combine bleeding site, hemodynamics, hemoglobin trend, and transfusion or procedural need. Major VKA bleeding calls for vitamin K and usually four-factor PCC according to the prescribed emergency protocol. Why the other choices are wrong Giving another warfarin dose worsens anticoagulation. Waiting for a scheduled INR ignores active critical-site and hemodynamic cues, and intramuscular injections can create additional bleeding in an anticoagulated client.

The client also has melena, blood pressure 92/58 mm Hg, an INR of 5.6, and a hemoglobin decrease of 2.4 g/dL from baseline. Emergency imaging, laboratory testing, and reversal therapy are available. ## Key concepts - **Major bleeding** — Bleeding at a critical site or associated with hemodynamic instability, a major hemoglobin decrease, or substantial transfusion need. - **Four-factor prothrombin complex concentrate** — A concentrated replacement of vitamin K-dependent clotting factors used for rapid reversal of vitamin K antagonists in major bleeding. - **International normalized ratio** — A standardized measure of prothrombin time used to monitor warfarin effect, interpreted together with clinical bleeding. ## Related questions - [A client is admitted to the emergency department after ingesting an unknown amount of acet…](https://mymerci.kr/pages/nclex_q.php?qn_id=362720&lang=en) - [A client with chronic heart failure is prescribed metoprolol 25 mg orally twice daily.
