Concept Map Cirrhosis (page 1198)

Evaluate the effects of chronic inflammation and necrosis resulting from cirrhosis (assess for jaundice, edema, ecchymosis, rashes, listen to bowel sounds, look for abdominal distention) 2. Prevent hemorrhage and death (monitor for complications) 3. Proteins provide some protection against bacteria and antibiotics if ordered to prevent infection (low grade fever, loss of appetite, pain, mental change s/s infection) 4. Monitor BUN, serum protein, H&H, platelets, and electrolytes 5. Drug Therapy: Antibiotics, Propranolol, Vasoconstrictors-octreotide (prevents or controls bleeding or infection with esophageal varices) - Thiamine for alcohol withdrawal 6. Daily weights, I&Os (pt. may be dehydrated, hypokalemic, hypernatremic) 7. Sodium Restriction (controls fluid excess) 8. Decrease Activity (to decrease pressure put on varices or abdominal distention strain) 9. Priority: PREVENTING INFECTION, protect skin integrity 10. Monitor for decreased LOC if patient is bleeding or has hepatic encephalopathy because this indicates decreased oxygenation to the brain

SIADH

-Increased ADH *HYPONATREMIA, decreased urine output, High BP -Fluid volume excess, Edema TX: Fluid restriction, Conivaptan (IV) or Tolvaptan (PO) to promote water excretion w/o losing sodium (these two drugs only given in hospital, closely monitor sodium levels)

Hiatal Hernia

-Increases intra-abdominal pressure -Complications include: volvulus (twisting of a GI structure), obstruction, GERD S/S: heartburn, belching, chest pain, dysphagia, fullness or breathlessness after eating, worsening when in recumbent position (feel worse lying down, so elevate HOB) -Management is aimed towards controlling reflux and treating the symptoms.
