Assessment Technique Diagnostic Evaluation
Inspection: • Skin changes Abdominal ultrasonography • Fast 8-12 hrs prior— decreases aniybt if gas in
supine c knees flexed • Nodules bowel
• Lesions: GI diseases often produce skin changes • Gallbladder studies: eat a fat free meal evening
• Scarring prior
• Discoloration • Barium studies should be scheduled after UTZ
• Inflammation • Moderate sedation: observe for 1 hr, assess for
• Bruising LOC, orientation, and ability to ambulate
• Striae
• Contour + symmetry of abdomen: flat, scaphoid, Upper GI tract study • Clear liquid diet
distended Barium sulfate • NPO midnight night before study
Diatrizoate sodium • No gum/smoking: increases gastric secretions +
Auscultation • Occur irregularly — 5-30 per minute salivation
Use diaphragm, soft clicks & gurgles • Normal: sounds heard every 5020 seconds • Polyethylene glycol (PEG): bowel cleansing
• Hypoactive: 1-2 sounds in 2 minutes agent.
Use bell for bruits over aortic, renal, and femoral • Hyperactive: 5-6 sounds in < 30 sec
arteries • Friction rubs are heard over liver and spleen during Lower GI tract study • Low residue diet 1-2 days before test
inspiration Barium enema • Clear liquid diet + laxative enema evening before
*begin in the RLQ • Borborygmi: loud prolonged gurgle Air contrast barium enema • Barium enemas should be scheduled before any
Diatrazoic acid if active inflamm dse, fistulas, or user GI series
perforation is suspected • Post procedure: increase pt fluid intake— barium
increases output.
Percussion Size + density of abdominal organs
Typmpani: air filled: stomach + small intestines CT-scan • W/ contrast: assess for iodine/shellfish allergy
Dullness: solid organs + masses • Kidney function: assess creatinine level
• Pregnancy status
Palpation Light palpation: Identify areas of tenderness or • IV sodium bicarb: 1 hr before & 6 hrs post study
muscular resistance • N-acetylcysteine (mucomyst) before/after study
Deep palpation: used to identify masses
MRI scan NPO 6-8 hrs
CI: pts w devices containing metal: pacemakers,
aneurysm clips, foil backed skin patches
Endoscopy Colonoscopy
• NPO 8 hrs • Adequate bowel prep
• Midazolam Versed) local anesthetic • Laxatives 2 nights prior to exam
• Atropoine: reduce secretions • PEG electrolyte lavage solutions (GoLYTELY)
• Left lateral position: facilitate clearanc of • 2-L PEG split dose for low risk pts
pulmonary secretions + provide smooth entry of • 4-L split dose with sodium picosulfate c
scope bisacodyl in pts c comorbidities
• Signs of perforation: pain, bleeding, dysphagia, • Clear liquid diet noon day before exam
rapidly inc temp • S/E: nausea, bloating, cramps, abdominal
• Hold food and fluids until gag reflex returns fullness, fluid and electrolyte imbalance,
hypothermia.
