Patients usually report an episode of non‑bloody vomiting followed minutes later by bright‑red hematemesis. The volume may be modest (often < 200 mL) but can be massive if a larger submucosal artery is torn. Vital‑sign trends—tachycardia, orthostatic hypotension, narrowing pulse pressure—signal volume depletion. Physical findings may include a pale, diaphoretic appearance; the abdomen is usually soft unless concomitant obstruction exists. Clinical trajectory check Link new findings to the underlying process and the compensatory response that is succeeding or failing. Reassess objective trends such as perfusion, oxygenation, mental status, pain pattern, labs, and response to time-limited interventions so the next action reflects improvement or deterioration rather than a memorized label.

For NCLEX-RN (Canada), items rarely announce the topic in the first sentence. Anchor to objective data, trajectory, and the safest next step...
