EXAM BLUEPRINT & CORE CLINICAL REFERENCE
Learning Objectives
1. Differentiate between the acute, fluctuating onset of delirium and the progressive, chronic decline of dementia [1,
2, 4, 17]. 2. Identify appropriate communication strategies (such as validation therapy and simple, structured
commands) for various stages of Alzheimer's disease [7, 14, 41]. 3. Assess safety priorities for disoriented, agitated,
or suicidal clients and implement appropriate behavioral limits [7, 8, 19, 25, 40]. 4. Evaluate psychiatric medication
profiles, identifying side effects, toxicities, and critical drug-food interactions for Lithium, MAOIs, TCAs, and
Antipsychotics [31, 32, 33, 45, 47, 51].
Clinical Terminology & Concepts
• Confabulation: The unconscious filling of memory gaps with fantasy. Not a conscious lie [10].
• Sundowning: A phenomenon of increased confusion and anxiety occurring in the early evening hours [30].
• Akathisia: An intense subjective feeling of motor restlessness, commonly induced by antipsychotics [93, 94].
• Apraxia / Dyspraxia: The inability to execute purposeful, learned motor tasks despite intact motor function [7, 75].
• Agnosia: Failure to recognize objects or familiar sensory stimuli despite normally functioning senses [32].
Commonly Confused Clinical Concepts
• Subjective vs. Objective Data: Subjective data are reports provided directly by the patient (e.g., pain, nausea,
anxiety). Objective data are information observed or measured by the clinician (e.g., heart rate, pupillary response).
• Delirium vs. Dementia: Delirium features an acute onset, fluctuating attention levels, and sympathetic autonomic
overactivity. Dementia features a slow, chronic decline with clear consciousness until late stages [2, 4, 17].
• Validation Therapy vs. Reality Orientation: Validation therapy acknowledges and validates the emotional
meaning behind a client's statements and is preferred in moderate-to-severe dementia [42, 44]. Reality orientation
reinforces basic orientation facts and is only appropriate in mild cognitive impairment when it does not induce distress
[1, 44].
• Displacement vs. Projection: Displacement involves redirecting a negative emotion (such as anger) to a safer,
less threatening recipient [68]. Projection involves taking one's own unacceptable feelings and ascribing them to
others [69].

Question 1: Nurse Isabelle enters the room of a client with a cognitive impairment disorder and
asks what day of the week it is; what the date, month, and year are; and where the client is. The
nurse is attempting to assess:
A. Confabulation.
B. Delirium.
C. Orientation.
D. Perseveration.
ANSWER ■: C — Orientation.
Explanation: Orientation is the assessment of awareness of time, place, and person. Real orientation reinforces
basic cognitive links and supports cognitive functioning for individuals with dementia. Confabulation involves
unconsciously filling memory gaps with fantasy. Delirium is an acute clinical syndrome of fluctuating
consciousness. Perseveration is the involuntary repetition of a specific response.
Question 2: A student nurse was asked which of the following best describes dementia. Which of
the following best describes the condition?
A. Memory loss occurring as part of the natural consequence of aging.
B. Difficulty coping with physical and psychological change.
C. Severe cognitive impairment that occurs rapidly.
D. Loss of cognitive abilities, impairing ability to perform activities of daily living.
ANSWER ■: D — Loss of cognitive abilities, impairing ability to perform activities of daily living.
Explanation: Dementia is a neurodegenerative disorder characterized by a global decline of cognitive abilities
(memory and other domains like personality, praxis, or executive function) that is severe enough to interfere with
normal activities of daily living and self-care. Memory loss is not a normal consequence of aging, and rapid
cognitive impairment is typical of delirium.
Question 3: Which of the following will Nurse Dory use when communicating with a client who has
cognitive impairment?
A. Complete explanations with multiple details.
B. Pictures or gestures instead of words.
C. Stimulating words and phrases to capture the client's attention.
D. Short words and simple sentences.
ANSWER ■: D — Short words and simple sentences.
Explanation: Short words and simple sentences minimize confusion and facilitate verbal communication for
clients with short attention spans or comprehension difficulties. Detailed explanations increase confusion. Pictures
and gestures may support but do not substitute for verbal communication. A quiet, non-stimulating environment is
preferred.

Question 4: Mrs. Mendoza is a 75-year-old client who has dementia of the Alzheimer’s type and
confabulates. The nurse understands that this client:
A. Denies confusion by being jovial.
B. Pretends to be someone else.
C. Rationalizes various behaviors.
D. Fills in memory gaps with fantasy.
ANSWER ■: D — Fills in memory gaps with fantasy.
Explanation: Confabulation is an unconscious communication device where memory gaps are filled with
fabricated or distorted events. The individual is not consciously attempting to deceive. Denial is refusing to
perceive reality. Reaction formation is adopting opposite behaviors. Rationalization is making excuses to minimize
anxiety.
Question 5: Which ability should Nurse Rebecca expect from a client in the mild stage of dementia
of the Alzheimer’s type?
A. Remembering the daily schedule.
B. Recalling past events.
C. Coping with anxiety.
D. Solving problems of daily living.
ANSWER ■: B — Recalling past events.
Explanation: In mild Alzheimer's disease, short-term episodic memory is typically impaired first, while long-term
memory (recalling past events) is preserved until late stages. Remembering schedules, coping, and complex
problem-solving are executive functions that show early decline.
Question 6: 82-year-old Mr. Robeson together with his daughter arrived at the medical-surgical
unit for diagnostic confirmation and management of probable delirium. Which statement by the
client’s daughter best supports the diagnosis?
A. "Maybe it's just caused by aging. This usually happens by age 82."
B. "The changes in his behavior came on so quickly! I wasn't sure what was happening."
C. "Dad just didn't seem to know what he was doing. He would forget what he had for breakfast."
D. "Dad has always been so independent. He's lived alone for years since mom died."
ANSWER ■: B — "The changes in his behavior came on so quickly! I wasn't sure what was
happening."
Explanation: Delirium is characterized by an acute, abrupt, and fluctuating onset of cognitive impairment and
altered consciousness. Dementia displays a slow, progressive decline (such as forgetting breakfast). Neither
cognitive disorder is a normal consequence of aging.
