Q1 QUESTION 1 OF 58
What was the previous name of Neurocognitive Disorder?
Page 1
, CORRECT ANSWER
Dementia
RATIONALE
The term "dementia" was previously used to describe a syndrome characterized by significant
cognitive decline, which is now clinically referred to as neurocognitive disorder. This shift reflects a
move towards more specific and descriptive diagnostic terminology in mental health.
Q2 QUESTION 2 OF 58
What are similarities between delirum and neurocogntive disorders?
CORRECT ANSWER
- Confusion/disorientatoin
- Impaired memory and attention span
- Anxiety and agitation
- Sundowning
RATIONALE
Both delirium and neurocognitive disorders can manifest with confusion, impaired memory,
attention deficits, agitation, and sundowning due to overlapping disruptions in cerebral function.
The key underlying concept is the shared symptomatology arising from altered cognitive
processing.
Q3 QUESTION 3 OF 58
What are risk factors of delirium?
CORRECT ANSWER
- Advanced age
- Liver/kidney failure
- FLuid/electrolyte imbalance
- Disease
- Infection
- Surgery
- Substance use
- Polypharmacy
- Males > Females
Page 2
, RATIONALE
Delirium is a multifactorial syndrome precipitated by underlying vulnerability (e.g., advanced age,
organ failure, polypharmacy) and acute insults (e.g., infection, surgery, substance withdrawal,
electrolyte imbalance), leading to altered mental status. The key underlying concept tested is the
identification of both predisposing and precipitating factors that contribute to the development of
acute brain dysfunction.
Q4 QUESTION 4 OF 58
What are risk factors of dementia?
CORRECT ANSWER
- Advance age
- Prior head trauma
- Cardiovascular disease/respiratory disease
- Lifestyle factors
- Family history
RATIONALE
Dementia risk is multifactorial, encompassing intrinsic biological factors like advanced age and
genetics, alongside acquired conditions such as head trauma and cardiovascular disease, and
modifiable lifestyle choices. These elements collectively impact brain health and increase
susceptibility to neurodegenerative processes.
Q5 QUESTION 5 OF 58
What are the effects of neurocognitive disorder?
CORRECT ANSWER
- Disruption of thinking , memory, processing, and problem solving
RATIONALE
Neurocognitive disorders fundamentally impair cognitive domains including intellect, recall,
information processing, and executive functions like problem-solving. This disruption manifests as
a decline in abilities necessary for daily functioning and independence.
