Document Summary
20 year old man hospitalized with crohn"s disease. Experienced nausea, anorexia, abdominal pain, and severe, bloody diarrhea. Direct pressure should be applied to the puncture site: b/c of the potential for hemorrhage from the artery pressure should be applied for at least. Bp does not need to be taken after arterial puncture. Does not need to be positioned in the fowler"s position after arterial puncture. Jackie is at risk for metabolic acidosis: he is primarily losing base ( bicarbonate, hco3) in diarrhea, an excess of acid in proportion to base can result. Remember: metabolic acidosis can occur when: acid production increases, acid accumulates, or bicarbonate (hco3, base) is lost. What conditions can contribute to metabolic acidosis: acute kidney failure. The kidneys regulate and maintain the level of base in the serum. When kidney failure occurs, the kidneys lose their ability to reabsorb bicarbonate (hco3, base) which causes serum bicarbonate to decrease.
