1. An older adult patient takes multiple medications daily. Over 2 days, the patient developed
confusion, slurred speech, an unsteady gait, and fluctuating levels of orientation. These
findings are most characteristic of:


a. delirium.


c. amnestic syndrome.


b. dementia.


d. Alzheimers disease.


a. delirium.


Delirium is characterized by an abrupt onset of fluctuating levels of awareness, clouded
consciousness, perceptual disturbances, and disturbed memory and orientation. The onset
of dementia or Alzheimers disease, a type of dementia, is more insidious. Amnestic
syndrome involves memory impairment without other cognitive problems.

2. A patient with fluctuating levels of awareness, confusion, and disturbed orientation shouts,
Bugs are crawling on my legs. Get them off! Which problem is the patient experiencing?


a. Aphasia


c. Tactile hallucinations


b. Dystonia


d. Mnemonic disturbance


c. Tactile hallucinations



The patient feels bugs crawling on both legs, even though no sensory stimulus is actually
present. This description meets the definition of a hallucination, a false sensory perception.
Tactile hallucinations may be part of the symptom constellation of delirium. Aphasia refers to
a speech disorder. Dystonia refers to excessive muscle tonus. Mnemonic disturbance is
associated with dementia rather than delirium.
