Palpation

  • Shallow
  • Deep
  • Costovertebral angle
  • Audio – normal bowel sounds

Percussion

  • General abdomen – tympany
  • Liver length

Tips

  • You can also check liver span by using the scratch test, where you listen with a stethoscope by periodically scratching as you move vertically.
  • When palpating for hepatomegaly or splenomegaly, start in the pelvis and move upwards.
  • If palpation on exam is resisted or unreliable, press with your stethoscope while listening to bowel sounds to get a better sense.
  • If presence of peritoneal signs is unclear, try bumping the bed and seeing if patient reacts.

  • Psoas sign – to assess appendicitis; raising leg against resistance causes RLQ pain
  • Obturator sign – to assess appendicitis; flexing and internally rotating leg causes pain
  • Rovsing sign – to assess appendicitis; pressing on LLQ will cause RLQ pain
  • McBurney’s point – to assess appendicitis; pushing down causing point tenderness
