Rebound Tenderness

Definition

Rebound tenderness is abdominal pain that occurs upon sudden release of pressure applied to a specific area, rather than during the application of pressure itself. It suggests peritoneal irritation or inflammation.

Associated Conditions

• Appendicitis (McBurney's point)
• Peritonitis
• Perforated ulcer
• Ectopic pregnancy rupture
• Diverticulitis
• Pelvic inflammatory disease

Assessment Technique

Press down gradually and deeply with fingers, then release quickly. A positive sign is sharp pain on release. Involuntary guarding (rigidity) often accompanies.

Nursing Interventions

Combined with rigid abdomen, fever, and tachycardia, suggests peritonitis, a surgical emergency. Priority: NPO, IV access, notify provider, prepare for imaging (CT) and possible surgery. Avoid analgesics that mask symptoms until diagnosis confirmed.

NCLEX Relevance

Classic appendicitis cue. Rebound tenderness + rigidity + fever = peritonitis emergency.
