What indicates a severe case of anticoagulant overdose?

  1. No symptoms appear

  2. Symptoms of cold and flu

  3. Presence of hematuria and melena

  4. Increased platelet count

The correct answer is: Presence of hematuria and melena

The presence of hematuria (blood in urine) and melena (dark, tarry stools) is indicative of a severe case of anticoagulant overdose. This is because anticoagulants, also known as blood thinners, prevent blood clots from forming and therefore can cause excessive bleeding. The other choices (A, B, and D) are not accurate indicators of a severe case of anticoagulant overdose. Option A is incorrect because despite no symptoms initially appearing, the person could still have an overdose. Option B is incorrect because symptoms of cold and flu are not typically related to anticoagulant overdose. Option D is incorrect because anticoagulants can actually decrease platelet count in some cases. Thus, option C is the most accurate indicator of a severe case of anticoagulant overdose.
