A client in a late stage of acquired immunodeficiency syndrome (AIDS) shows signs of AIDS-related dementia. Which nursing diagnosis takes highest priority?
Correct Answer: C
Rationale: The nursing diagnosis that takes the highest priority for a client in a late stage of AIDS with signs of AIDS-related dementia is Ineffective cerebral tissue perfusion. This diagnosis is prioritized because AIDS-related dementia is associated with changes in brain function due to HIV affecting the brain tissues. Ensuring adequate cerebral perfusion is crucial to maintaining brain function and preventing further deterioration. Monitoring and addressing any factors that could affect cerebral perfusion, such as blood pressure, oxygenation, and circulation, are essential in managing this condition. Other nursing diagnoses are also important, but addressing ineffective cerebral tissue perfusion should be the highest priority in this situation to prevent further complications related to neurological function.
