A patient who has portal systemic encephalopathy is receiving Neomycin (neomycin sulfate). Which manifestation should indicate to the nurse that the patient's condition is improving?
1. increase in potassium level
2. asterixis
3. relief of jaundice
4. increased level of consciousness
Correct Answer: 4
Portal systemic encephalopathy is characterized by impaired judgment, confusion, disorientation, and incoherence related to high level of ammonia in the blood. Administering Neomycin (neomycin sulfate) should reduce ammonia levels by decreasing the number of bacteria-producing microorganisms in the bowel. Neomycin (neomycin sulfate) causes diarrhea, which decreases rather than increases potassium. Asterixis, the downward flapping of the hands, is a sign of portal systemic encephalopathy and should improve with administration of Neomycin (neomycin sulfate). Neomycin does not improve jaundice.
