Introduce

‘I’m now going to examine your abdomen. Are you ok lying flat? We can use this sheet/your gown/bra to cover your chest.’

Exposure: Nipples to knees (in practice sheet covers external genitalia.)
Position: Lower bed flat, with patient resting on one pillow. Arms by sides.

Inspect
Distension, scars (ask patient to identify), drains and stomas (follow the drain and see what is draining. Identify type of stoma), masses, vessels, striae, hernias.
‘Can you raise your head off the pillow for me. Can you breathe in and out. Can you suck your tummy in and puff it out as best you can. And can you give a cough.’ ‘What is this scar from?’

Palpation & Percussion
Assess for a triple A by placing hands either side of umbilicus.
Feel for hernias in inguinal region and ask patient to cough.
‘I’m going to feel for a pulse in your groin and feel for any hernias.’
Squat by side of bed so patient’s abdomen is at eye level. ‘I’m going to feel your abdomen. Are you in any pain?’ Look at patient’s face and begin light palpation at point farthest from pain. Palpate in the four quadrants.
‘I’m going to press a little more firmly now.’
Palpating a mass: feel for size, shape, surface, consistency, mobility, pulsatile nature, movement with respiration.

Percuss Liver - map upper and lower borders of liver.

Percuss Spleen - percuss from umbilicus to left costal margin. Unable to map top due to heart

Kidneys: Place left hand behind right loin Place right hand at costal margin. Push down with right hand balloting the kidney. Repeat for left kidney.
