A multidisciplinary team working with the spouse of a home care client who has end-stage liver failure is teaching the spouse about pain management. Which statement by the spouse indicates the need for further teaching?

In the client with liver disease, the ability to metabolize medication is affected. A decreased level of consciousness is a potential clinical indicator of medication overdose, as well as fluid, electrolyte, and oxygenation deficiencies; thus, the nurse teaches the client's spouse about the differences between sleep related to pain relief and a deteriorating change in neurological status. Options 1, 2, and 3 all indicate an understanding of suitable steps to be taken in pain management.
