When planning care for a patient with colon cancer experiencing lower gastrointestinal bleeding, which intervention should be prioritized?

Choice A reason: In any case of active gastrointestinal bleeding, the most immediate threat to life is hemodynamic collapse. Monitoring vital signs—specifically checking for tachycardia, hypotension, and tachypnea—allows for the early detection of hypovolemic shock. This assessment is the priority to guide emergency fluid resuscitation and stabilization efforts. Choice B reason: While hydration is important, oral intake is not the priority during an acute bleed. The patient may need to be NPO for diagnostic procedures like a colonoscopy or emergency surgery. Furthermore, if the bleed is severe, oral fluids are insufficient to replace lost blood volume; intravenous access for fluids or blood products is required. Choice C reason: Ibuprofen is a non-steroidal anti-inflammatory drug (NSAID) that can inhibit platelet aggregation and irritate the gastrointestinal mucosa. Administering an NSAID to a patient with an active GI bleed is dangerous and contraindicated, as it can worsen the bleeding and interfere with the body's natural clotting mechanisms. Choice D reason: Physical therapy is a long-term rehabilitative intervention and is completely inappropriate for a patient experiencing an acute medical emergency like a GI bleed. The patient should remain on bed rest to minimize oxygen demand and prevent syncopal episodes while their hemodynamic status is being assessed and stabilized.
