Correct answer: C — Arrange urgent ultrasound and air/contrast enema reduction if stable

Arrange urgent ultrasound and air/contrast enema reduction if stable is best because episodic pain, vomiting and bloody stool suggest intussusception. Discharge with oral analgesia only is suboptimal because analgesia alone may mask a surgical emergency; Delay surgical assessment until routine clinic is suboptimal because time-sensitive surgical presentations require urgent assessment; Treat with laxatives or antacids as sole therapy is suboptimal because a benign gastrointestinal explanation does not account for the red flags; Perform an invasive bedside procedure without imaging or senior input is suboptimal because invasive treatment can worsen outcomes when anatomy or diagnosis is uncertain. Peritonitis or perforation requires surgery rather than enema.
