The nurse is caring for a client who states: 'Can you tell this man sitting on the chair to leave my room. I am tired of him watching me.' The nurse notes that there is no one else in the room. The nurse would document the client's experience as which of the following?
- A. Delusion
- B. Dementia
- C. Hallucination
- D. Delirium
Correct Answer: C
Rationale: The nurse is correct to document the client's experience of a man in the room as a hallucination. Hallucinations are sensory experiences only the client perceives. They are auditory or visual in nature. A delusion is characterized by a disturbed thinking process. Dementia is the disturbance or decline in memory. Delirium is a sudden state of confusion.

The client asks the nurse if there is a diagnostic test that confirms the diagnosis of Alzheimer disease. Which response by the nurse identifies how the diagnosis is confirmed?
- A. Alzheimer disease is confirmed by validating mental decline and ruling out other diseases.
- B. Alzheimer disease is confirmed by the presence of biomarkers found in the blood.
- C. Alzheimer disease is evident on an MRI that highlights tangles in the brain.
- D. Alzheimer disease is diagnosed when acetylcholine is found in spinal fluid.
Correct Answer: A
Rationale: Much research is being done to determine a diagnostic test confirming Alzheimer disease. The nurse is most correct to confirm that Alzheimer disease is currently validated by noting mental decline and ruling out all other disease processes. Upon autopsy, neurofibrillary tangles are noted. There currently is not a test using biomarkers for Alzheimer disease. An MRI is used to exclude other disease processes and is not specific for Alzheimer disease. Acetylcholine may result in cognitive deficits but is not found in the spinal fluid.
The nurse is discharging four clients from the behavioral health unit. Which client would be the best candidate for long-term inpatient care?
- A. The client experiencing hallucinations
- B. The client with feelings of persecution
- C. The client with a love interest
- D. The client with suspicion and anger
Correct Answer: D
Rationale: Once a client is in the mental health system, every effort is made to avoid institutionalization. The exception is when the client is dangerous to self and others. The nurse is most correct to anticipate the client with suspicion and anger to be the best candidate for long-term inpatient care. Clients who have hallucinations or feelings of persecution and those with a love interest being discharged from a behavioral health unit can be monitored in an outpatient setting.
Which of the following is the primary reason for monitoring food and fluid intake and toilet patterns of a client with mental disabilities?
- A. Regular checkup
- B. To identify problems
- C. To determine common symptoms
- D. Physician's record

Rationale: The nurse monitors food and fluid intake and toilet patterns because data collection facilitates problem identification, not as part of a regular checkup or for determining common symptoms. The physician may refer to these records whenever required.
The nurse is relating medication classifications for Alzheimer type dementia to the pathophysiology of the disease process. Which neurotransmitter do most the medications on the market currently impact?
- A. Dopamine
- B. Acetylcholine
- C. Norepinephrine
- D. Epinephrine
Correct Answer: B
Rationale: Current drugs approved for treatment of dementia of the Alzheimer type include cholinesterase inhibitors, which increase acetylcholine by inhibiting cholinesterase, the enzyme that degrades it. When these drugs, tacrine (Cognex), donepezil (Aricept), or rivastigmine (Exelon), are administered in the early to middle stages of Alzheimer disease, some clients improve. Only memantine (Namenda) has a different mechanism of action.
