The abdomen is a large oval cavity extending from the diaphragm down to the brim of the pelvis.
1. Borders
2. Abdominal muscles
1. Bordered in back by the vertebral column and paravertebral muscles, at the sides and front by the lower rib cage and abdominal muscles
2. 4 layers of large, flat muscles form the ventral abdominal wall (rectus abdomninis, external oblique, internal oblique, transversus)

Internal Organs
Internal Organs
1. Liver location?
2. Palpable?
3. Kidney's palpable?
4. Ovaries palpable?
1. fills most of the right upper quadrant and extends over to the left midclavicular line
2. lower edge is palpable
3. right kidney normally can be palpable
4. ovaries normally palpable only on bimanual examination during pelvic exam
1. Spleen location?
2. Palpable?
1. soft mass of lymphatic tissue on the posterolateral wall of the abdominal cavity immediately under the diaphragm and lies obliquely with its long axis behind/parallel to the 10th rib
2. not normally palpable, if enlarged its lower pole moves downard and toward the midlne
The Pancreas is?
soft, lobulated gland located behind the stomach, stretches obliquely across the posterior abdominal wall to the left upper quadrant
Kidneys are?
bean shaped, are retroperitoneal or posterior to the abdominal contents, protected by the posterior ribs and musculature.
Costovertebral angle?
The 12th rib forms an angle with the vertebral column
Because of the placement of the liver, the right kidney?
rests 1 to 2 cm lower than the left kidney and sometimes may be palpable
Four Quadrants
Picture of kidneys
Anatomic locations of organ and quadrant
Aorta is just left of the midline in upper part of the abdomen, bifurcates into the right and left common iliac arteries opposite of the 4th lumbar, they become left and right femoral arteries. all palpable.
Function of the GI
Secretion, digestion, absorption, motility, elimination
Alimentary Tract
- mouth
- esophagus
- stomach
- small intestine: movement, digestion, absorption
- large intestine: colon & rectum: movement, absorption, elimination
Accessory organs
- liver: storage, protection, metabolism
- gallbladder: collects, concentrates, stores bile from liver, releases bile into duodenum
- pancreas: exocrine and endocrine
- spleen
Urinary Tract
- kidney: regulatory and hormonal functions
- ureters
- bladder
Refered Abdominal Pain
Developmental Considerations
Infants and Children
- digestive organs begin to form at 4 weeks gestation
- Infants abdomen less muscular, easy to palpate organs
Developmental Considerations
Pregnant Female
- abdominal muscles lose tone
- stomach displaced upwards: GERD
- peristaltic activity decreased and water absorption increased: constipation
- hemorrhoid formation occurs
- bladder compression
- decreased gallbladder emptying
- bowel sounds diminished-intestines displaced upward and posteriorly
Developmental Considerations
- aging causes adipose tissue to redistribute away from face and extremities and to abdomen and hips
- liver size decreases leading to altered metabolism
- esophageal emptying delayed
- altered intestinal motility
- decreased gastric secretion
- delayed colon and rectal emptying: constipation

Preparation for Objective Data
- Use good lighting
- Enhance abdominal wall relaxation:
- empty bladder
- keep room warm
- position supie, head on pillow, arms to sides relaxed
- avoid abdominal tensing, keep hands, fingers, tools warms
- use distraction, breathing exercises, emotive imagery, low soothing voice, patient talk while palpating
1. check contour profile from rib margin to pubic bone
2. check symmetry
3. check umbilicus
1. flat, rounded, protuberant, scaphoid
2. bulges, masses or hernia
3. central without displacement, inverted or protruded slightly, free of inflammation, swelling, or bulges that indicate hernia, color should be consistent with body
Cullens sign?
Bluish periumbilical color occurs with intraabdominal bleeding
Inspection of Skin - Abnormal on back
- surface is smooth, even, homogenous color
- striae is common pigment
- pigmented nevi, brown macular or papular areas are common on abdomen
- surgical scars, draw its location on record in cm
- veins usually not seen, fine venous network ok
- pulsations or aorta, peristalsis ok
- pattern of pubic hair normal
- demeanor=relaxed, benign expression, slow even respirations
- purple-blue striae are Cushing's systdrome
- striae occur with pregnancy + ascites
- cutaneous angiomas (spider nevi) occur with portal HTN liver disease
- veins are more visible with malnutrition
- poor turgor=dehydration
- altered pubic hair patterns occur with hormone abnormality and chronic liver disease
- absolute stillness, resisting any movement occurs with peritonitis
Potential causes of abdominal distention:
- obesity
- air or gas
- ascites
- ovarian cyst
- pregnancy
- feces
- tumor
Ascites is collection of free fluid in peritoneal cavity by increased hydrostatic pressure from portal HTN
- Diaphragm and press LIGHTLY
- Bowel sounds
- listen in all 4 quads starting in RLQ
- normal = gurgles 5-30 times per minute
- silent abdomen is uncommon must listen for 5 minutes before stating it is absent of sound
- Borborygmus is normal=stomach growling
Abnormal Bowel Sounds
1. Hyperactive
2. Hypoactive
1. sounds are loud, high-pitched, rushing, tinkling sounds signal increased motility
2. absent sounds follow abdominal surgery or with inflammation of the peritoneum
Vascular Sounds (house shape)
- listen for bruits w/bell w/firm pressure
Rrenal Lrenal

Riliac Liliac

Rfemoral Lfemoral
- all 4 quadrants
- should predominantly be tympanic (air)
- dullness occurs?
- hyperresonance occurs?
- dullness occurs over a distended bladder, adipose tissue, fluid, or a mass
- hyperresonance is present with gaseous distention
Percuss for liver span
- percuss downward at the right MCL from resonance to dullness, mark area (5-7th ICS)
- percuss upward at the right MCL from tympany to dullness, mark area
- span is usually 6-12 cm
- (males=10.5cm) (females=7cm)
Percussion of Liver using Scratch Test
- place stethoscope over liver
- scratch the abdomen lightly from the RLQ upwards
- when the sound becomes magnified you are at the liver
- what is Hepatomegaly?
- enlarged liver span
- percuss for a dull note from the 9th to 11th ICS behind the left midaxillary line MAL
- usually less than 7 cm
- percuss in the lowest interspace in the left anterior axillary line AAL=tympanic
- deep breath=should remain tympanic
- what is splenomegaly?
enlarged spleen occurs when percussion becomes dull from tympany, also mononucleosis, malaria, hepatic cirrhosis
Percuss for CVA costovertebral angle
- indirect fist percussion causes the tissues to vibrate instead of producing a sound
- assess the kidney at 12th rib at the costovertebral angle on lower left back
- place hand over and thump with ulnar edge
- thud should be felt but no pain
Assessing Ascites-Fluid Wave
- patient has bulging flanks, distended abdomen, protruding umbilicus
- differentiate ascites from gaseous distention
1. assess for fluid wave: large amounts of fluids
1. stand on patient's right side (patient supine)
2. place ulnar edge of patients hand firmly on abdomen in the midline
3. place your left hand on person's right flank
4. with right hand, reach across abdomen and give the left flank a firm strike
4. if ascites present, fluid wave will be present and will tap left hand
5. if distention is due to gas or adipose tissue no tap will be present across the abdomen
Assessing Ascites-Shifting Dullness (percussion)
- patient has bulging flanks, distended abdomen, protruding umbilicus
- differentiate ascites from gaseous distention
1. assess for Shifting dullness: > 500mL
2. NOTE it will not detect < 500mL
1. ascites fluid settles by gravity into the flanks, displacing the air-filled bowel upward
2. should hear tympanic over the top of the abdomen due to gas-filled intestines float over the fluid
3. percuss down the side of the abdomen and mark the location as it goes from tympanic to dull
4. roll patient toward you or on right side
5. fluid will gravitate to the dependent side, dispacing the lighter bowel upward
6. percuss the upper side of the abdomen and move downward until you reach dullness and mark this spot
7. this new level should up higher towards umbilicus
Picture of Ascites
**NOTE** Ultrasound is only definitive tool
Palpation is used to judge the size, location, consistency of certain organs and to screen for abnormal mass or tenderness
1. use additional measure to ensure patient comfort and muscle relaxness
1. bend patient's knees
2. keep your palpating hand low and parallel to the abdomen
3. teach patient to breathe slowly (in nose, out mouth)
4. keep your own voice low and soothing, conversate
5. use emotive imagery (scene of a beach on nice day)
6. with ticklish person, keep their hand under your own
7. alternative method is to palpate right after percussing using the stethoscope as a distractionary tool
1. Light palpation
2. Deep palpation
1. palpate lightly using finger pads in all 4 quadrants about 1 cm deep look for with gentle rotary motion do not drag fingers as you move from spot to spot:
2. palpate deeply 5-8 cm deep, to overcome obese/muscular use bimanual technique (top hand pushes, bottom hand palpates)
3. note location, size, consistency and mobility of any palpable organs and presence of any abnormal enlargement, tenderness, or masses
4. voluntary guarding is normal reaction to cold, tense, or ticklish and is bilateral
5. look for involuntary rigidity, it is constant board like hardness of the muscles, may be unilateral and protective mechanism of inflammation of the peritoneum, can be painful when trying to sit up
Organs normally palpated
- Liver
- Spleen
- Kidney
- Aorta
Mild tenderness normally is present when palpating ? Any other tenderness should be investigated.
If mass identified note the following?
1. Sigmoid colon
2. Location, Size, Shape, Consistency (soft, firm, hard), Surface (smooth, nodular), Mobility, Pulsatility, Tenderness
Palpating Liver
1. palpate in RUQ for borders
2. place left hand in back 11th to 12th rib
3. place right hand on RUQ with fingers parallel to midline
4. press deeply down and under right costal margin while patient inhales deeply
5. normal is to feel liver bump fingers as diaphragm pushes it down
Hook Technique for Liver Palpation
- stand up at the person's shoulder, face their feet, hook fingers over the costal margin, during inhalation feel for liver bumping against your fingertips
Palpating Spleen
1. place left hand over patients abdomen and behind left side at 11th and 12th rib, lifting to support
2. place right hand on LUQ with fingers pointing to axilla just below rib margin
3. push down and under the left costal margin while the patient is breathing deeply
If Spleen is enlarged it may be displaced if you suspect this you can?
Roll the person onto his right side to displace the spleen more forward and downward, then proceed with normal palpation technique
Palpate the kidneys
1. right kidney (yes palpable)
2. left kidney (not normally palpable)
1. place hands together in a "ducks bill" in right flank while patient takes a deep breath, press 2 hands together firmly, may feel slight round, smooth, mass
2. reach left hand across abdomen and behind the left flank, push your right hand deep into abdomen while person breathes deeply, should not be palpable
Palpate the Aorta
- use your opposing thumbs and fingers (like pinching) to palpate the aortic puslation and upper abdomen slightly left of midline
- normal is 2.5 to 4 cm wide
- 80% of aneurysms palpable
1. enlarged liver
2. enlarged nodular liver
3. enlarged gallbladder
4. enlarged spleen
5. enlarged kidney
6. aortic aneurysm
1. smooth, nontender, occurs with fatty infiltration, portal obstruction or cirrhosis and lymphocytic leukemia
2. nodular occurs with late portal cirrhosis, metastic cancer or tertiary syphilis
3. tender suggests acute cholecystitis, involuntary rigidity, area is painful to fist percussion and inspiratory arrest (Murph's sign) enlarged nontender has stones
4. it enlarges down and midline, acute is soft with round edges and chronic is firm and hard with sharp edges, tenderness is associated with inflammation of peritoneum
5. occurs with hydronephrosis, cyst or neoplasm, has splenic notch, spleen is dull to percussion, kidney is not
6. 95% located below renal arteries, 80% palpable during routine physical examination and feel like pulsating mass in upper abdomen just left of midline, bruit will be heard
Rebound Tenderness (Blumberg's sign)
- press deeply into abdomen, remote from the area of discomfort
- hold hand at 90 degree angle and push slowly, deeply
- rapidly withdraw hand and fingers and assess for sharp stabbing pain, normal=no pain
Murphy's Sign (inspiratory arrest)
- hold fingers perpendicular under liver border
- ask person to take a deep breath
- normal=no pain during inspiration
Test for Appendicities
1. iliopsoas muscle test (w/acute appendicitis)
2. obturator test (ruptured appendix, pelvic abscess)
1. with person supine, examiner lifts right leg straight up, flexing at hip, then push down over thigh as patient tries to resist and hold leg up, normal=no pain
2. with patient supine, lift right leg, flexing at hip and 90 degree angle at knee, hold ankle and rotate leg internally and externally (sitting indian style) normal=no pain
Abdominal Reflexes
- patient in supine position with knees slightly bent
- use handle end of reflex hammer, wood applicator tip, to stroke the skin from side of abdomen to midline
