When used for treatment of patients diagnosed with Alzheimer's disease, which medication would be expected to antagonize N-methyl-D-aspartate (NMDA) channels rather than cholinesterase?
- A. Donepezil
- B. Rivastigmine
- C. Memantine
- D. Galantamine
Correct Answer: C
Rationale: Memantine blocks the NMDA channels and is used in moderate-to-late stages of the disease. Donepezil, rivastigmine, and galantamine are all cholinesterase inhibitors. These drugs increase the availability of acetylcholine and are most often used to treat mild-to-moderate Alzheimer's disease.
A patient diagnosed with stage 2 moderate Alzheimer's disease calls the police saying, 'An intruder is in my home.' Police investigate and discover the patient misinterpreted a reflection in the mirror as an intruder. This phenomenon can be characterized using which term?
- A. Hyperorality
- B. Aphasia
- C. Apraxia
- D. Agnosia
Correct Answer: D
Rationale: Agnosia is the inability to recognize familiar objects, parts of one's body, or one's own reflection in a mirror. Hyperorality refers to placing objects in the mouth. Aphasia refers to the loss of language ability. Apraxia refers to the loss of purposeful movements, such as being unable to dress.
A nurse should anticipate that which symptoms of Alzheimer's disease will become apparent as the disease progresses from stage 3, moderate to severe to stage 4, late stage?
- A. Agraphia
- B. Hyperorality
- C. Fine motor tremors
- D. Hypermetamorphosis
- E. Improvement of memory
Correct Answer: A,B,D
Rationale: The memories of patients with Alzheimer's disease continue to deteriorate. These patients demonstrate the inability to read or write (agraphia), the need to put everything into the mouth (hyperorality), and the need to touch everything (hypermetamorphosis). Fine motor tremors are associated with alcohol withdrawal delirium, not dementia. Memory does not improve.
What is the priority nursing need for a patient diagnosed with late-stage dementia?
- A. Promotion of self-care activities
- B. Meaningful verbal communication
- C. Maintenance of nutrition and hydration
- D. Prevention of the patient from wandering
Correct Answer: C
Rationale: In late-stage dementia, the patient has often forgotten how to eat, chew, and swallow. Nutrition and hydration needs must be met if the patient is to live. The patient is incapable of self-care, ambulation, or verbal communication.
Two patients in a residential care facility are diagnosed with dementia. One shouts to the other, 'Move along, you're blocking the road.' The other patient turns, shakes a fist, and shouts, 'I know what you're up to; you're trying to steal my car.' What is the nurse's best action?
- A. Administer one dose of an antipsychotic medication to both patients.
- B. Reinforce reality. Say to the patients, 'Walk along in the hall. This is not a traffic intersection.'
- C. Separate and distract the patients. Take one to the day room and the other to an activities area.
- D. Step between the two patients and say, 'Please quiet down. We do not allow violence here.'
Correct Answer: C
Rationale: Separating and distracting prevents escalation from verbal to physical acting out. Neither patient loses self-esteem during this intervention. Medication is probably not necessary. Stepping between two angry, threatening patients is an unsafe action, and trying to reinforce reality during an angry outburst will probably not be successful when the patients are cognitively impaired.
