The patient who vomited bright red blood is exhibiting active bleeding that is likely due to NSAID administration. This patient should be assessed first. The patient with dark, tarry stools should also be assessed quickly, but dark, tarry stools may reflect a slower pathophysiology than active bleeding in the stomach. The patient with new onset tinnitus should be assessed for signs of NSAID toxicity, but this manifestation is less life-threatening than gastrointestinal bleeding. The patient taking aspirin who sustains a small cut while shaving is at risk for prolonged bleeding, but the answer option does not suggest the patient is exsanguinating; this patient can wait.
