A 74-year-old man presents to the emergency department after passing a large volume of bright red blood per rectum. He denies abdominal pain, nausea, vomiting, or fever. His medical history is significant for hypertension, coronary artery disease, and diverticulosis. Medications include aspirin, metoprolol, and atorvastatin. Temperature is 36.9°C (98.4°F), blood pressure is 92/58 mm Hg, pulse is 118/min, and respiratory rate is 22/min. Physical examination reveals pale conjunctiva and delayed capillary refill. Rectal examination confirms bright red blood.
Which of the following is the most appropriate initial management?
The correct answer is:
B: Intravenous fluids and hemodynamic stabilization.
This patient has a hemodynamically significant acute lower gastrointestinal bleed. Initial management follows the principles of resuscitation, including intravenous fluids, blood products when indicated, and stabilization before diagnostic procedures. Stabilization always takes priority over definitive localization of bleeding.
Answer choice A: Colonoscopy immediately, is incorrect.
Colonoscopy is often used after stabilization, but unstable patients require resuscitation first.
Answer choice C: Oral iron supplementation, is incorrect.
Iron therapy does not address acute blood loss or hemodynamic instability.
Answer choice D: Outpatient gastroenterology referral, is incorrect.
The patient’s hypotension and tachycardia require immediate inpatient management.
Answer choice E: Sigmoidoscopy, is incorrect.
Limited endoscopic evaluation is unlikely to identify the bleeding source and should not precede stabilization.
Key Learning Point
In patients with significant gastrointestinal bleeding, hemodynamic stabilization is the first priority before diagnostic procedures.
