midline, between costal margins
Where is the umbilical region?
Around the umbilicus :)
makes sense, right???

above the pubic bone....
for example, a full bladder gives suprapubic distention.
What is on the midline of the ABD?

What are the hollow organs (that are usually not palpable)?
- small intestine
What does the right ribcage protect?
- right kidney
What does the left rib cage protect?
What is the umbilical cord composed of?
2 arteries and 1 vein
What are the developmental considerations of infant and children (in concern to the abdomen)?
- umbilical cord
- liver takes up more space in ABD
- bladder lies higher in ABD cavity (between symphysis pubis and umbilicus)

What is morning sickness r/t (related to)?
increased HCG [Human chorionis gonadotropin]- occurs in 1st trimester in 50-75% of individuals. Starts in 4th -6th week
What are the ABD concerns with pregnancy?
- Morning sickness
- Heartburn (r/t increased esophageal reflux 2 degree increased pressure from displaced ABD organs)
- Decreased GI motility (constipation)
- Increase pressure on venous system (hemmorrhoids, varicosities)
- Enlarging uterus (decreased bowel sounds r/t displacement of intestines upward and posterior)
- ABD skin changes
What developmental considerations do we see with Aging Adults in regards to their ABD?
- Increased adipose tissue on ABD
- Decreased salvation and taste
- Delayed gastric emptying (increases risk for aspiration with supine)
- Decreased gastric acid secretion (may cause altered B12 absorption, Fe deficiency anemia and calcium malabsorption)
- Increased incidence of gallstones
- Decreased liver size (impaired drug metabolism)
- Increased constipation
What does "start low, go slow mean?"
Start with lowest dose of a drug and advance slowly
difficulty swallowing indicating a problem with throat or esophagus
pain upon swallowing
gastric bloating r/t decreased lactase (enzyme for digesting lactose). This is not an allergic, histamine, response, but rather an intolerance; subsequent exposure will not be harmful.
What is a potential side affect with use of NSAIDS (particularily in the elderly?)
Even low doses may be harmful fr the elderly; risk of GI bleed. Always take with food to decrease this risk.
If they have N/V, what do you want to consider?
- Consider potential med side effects
- presence of fever/chills (infection)
- tiem of last meal (food poisioning)
- Hematemesis (blood)
black tarry stool= upper GI bleed (ulcer)
Fe, bismuth (peptobismal)
maroon stools; usually lower GI bleeding; may be UGI bleed if rapid GI motility present.
bright red blood per rectum.
Means lower GI bleed, e.g. hemmorrhoids
Clay colored stools
Decreased caliber of stool-- pencil thin
Obstruction (cancer), or decreased fiber
What are fissures (linear creacks in rectal mucosa) related to?
may be related to constipation adn hemmorrhoids
Destention (7 Fs)
- flatus (gas in GI)
- fatal mass
What are problems that ETOH (alcohol) can cause in the GI system?
GI ulceration, liver problems
What is a problem that nicotine can cause in the GI tract?
increased incidence of peptic ulcers
How will you position the patient for an ABD exam?
increase the HOB, patient's arms at side, full exposure of ABD, empty bladder, use good lighting, examiners nails should be short
What is accentuated when the patient does a little sit up for us?
accentuates ventral (ABD) hernias
What is diatis recti?
What are you looking for when you examine the umbilicus?
should be midline with no sign of discoloration, inflammation or hernia
Are pulsations from the aorta in the ABD normal?
yes, we may see some pulsations, but marked pulsations may indicate an aneurysm
What does peristalsis indicate?
Well, it can be normal to see in a thin person, or it may indicate an early bowel obstruction
What could an everted umbilicus mean?
- acites or underlying mass
What are striae?
stretch marks; color initially pink or blue, then white
What are purple striae related to?
cushing's syndrome (excess adrenocortical hormone)
What are acites associated with?
What are cutaneous angiomas
What can petechia and cutaneous angiomas signify?
liver disease (just an example)
What is a cause of prominent dialated veins?
Portal HTN (cirrhosis, ascites) or inderior vena cava obstruction

What is the normal frequency of bowel sounds?
5-30 per minute, listen up to 5 minutes until they are heard
What can greater than 30 bowel sounds per minute indicate?
hyperactive bowel-- rushing, tinkling. may indicate early bowel obstruction
What are the causes of hypoactive or absent bowel sounds?
- *abdominal surgery results in a paralytic ileus (absence of GI motility and BS)- mat take up to 48 hours for BS to return
- *bowel obstruction
What are the vascular sounds that we listen to in the ABD?
- *listen with the bell of the stethoscope
What does percussion detect?
distention, fluid, masses
What is the normal sound for percussion in most of the abd?
Where will you hear dullness while percussing the abd?
liver, distended bladder, adipose tissue, fluid, feces, mass
When will you find hyperresonance while percussing?
present with gaseous distention
What are the normal findings for liver span?
- RMCL- 6-12 cm. 5th ICS to R costal margin
- midsternal line (4-8cm) usually not measured
enlargement of the liver. greater than 12 cm at RMCL
displace the liver downwards
How large is the spleen normally?
Less than 7 cm while percussing
extends medial to MAL-- mononucleosis, trauma, leukemia
indicates kidney infection. Over 12th rib
What is a good position for palpation of the ABD?
bend knees, have patient relax ABD muscles
what is muscle guarding?
tightening abd muscles
What is rigidity?
hardness decondary to inflammation
How far down do you depress for light palpation?
- watch for involuntary guarding(board-like hardness)
what is deep palpation?
greater than 1 cm
What do you write down if you find a palpable mass?
describe location, size, shape, consistency, surface, mobility, pulsatility, tenderness
How do you palpate the liver border?
- feel edge at RUQ with deep inspiration; usually non-palpable.
- Abnormal if greater than 1-2 cm below right costal margin.
- inferior border should be smooth. If it is not, may indicate a heptoma
Function of Spleen
- Forms monocytes and lymphocytes
- Stores RBC adn releases into circulation if needed
- Filters old RBCs from blood
***Must be 3x normal size to palpate. But stop palpation if enlarged-- may rupture!! May extend to LLQ
If the aortic pulsation is far to the left, what may that indicate?
an AAA (abd aortic anneurysm)
What is the test for peritoneal inflammation (ruptured appendix, PID)?
- Rebound tenderness----
- deep palpation with quick withdrawl (hand at 90 degrees)
- Positive test (pain with quick release)
What is Murphy's sign?
- Positive test (inspiratory arrest with deep palpation under liver)
Considerations for infant/child exam
- *normally has protruberant contour until age 4
- *umbilical hernia:
- - may appear in 2-3 weekds
- - reaches max size by one month (2.5cm)
- - disappears by 1 year
- *Diastasis recti (separation of rectus ABD muscles causing bulge along midline)
- *ABD breathing until age 7 (normal)
