Accepted Answer

Delirium tremens is a severe form of acute alcohol withdrawal that can occur in individuals with a history of heavy and prolonged alcohol use. Symptoms include confusion, disorientation, hallucinations, agitation, tremors, and seizures. It is a medical emergency that requires immediate treatment. Withdrawal from benzodiazepines or opioids can also cause delirium, but they present with different symptoms. High fever is not typically associated with delirium tremens.

Question 2

Which one of the following is not included in the list of characteristic cognitive symptoms of traumatic brain injury?

Accepted Answer

Accepted Answer

C

Question 4

In 2016, the annual total health care costs of caring for people with dementia in Canada was:

Accepted Answer

In 2016, the annual total health care costs of caring for people with dementia in Canada was estimated to be 10.4 billion dollars, reflecting the significant economic impact of this condition on the healthcare system.

Question 5

Question 6

What per cent of patients in intensive care units have an alcohol use disorder and are at risk of developing alcohol withdrawal delirium?

Accepted Answer

Up to 31% of patients in intensive care units have an alcohol use disorder and are at risk of developing alcohol withdrawal delirium.

Question 8

According to the WHO, how many people worldwide suffer from dementia?

Accepted Answer

According to the WHO, approximately 50 million people worldwide suffer from dementia.

Question 9

Factors contributing to a decline in the incidence of dementia in the United States include:

Accepted Answer

Improved treatments for cardiovascular risk factors, such as high blood pressure and diabetes, have been shown to lower the risk of developing cognitive decline and dementia. Other factors listed may contribute to overall health and well-being, but there is less evidence linking them specifically to a decline in dementia incidence.

Question 10

Which one of the following is not included in the list of medical conditions causing delirium?

Accepted Answer

Chronic Fatigue is not typically associated with delirium. Brain tumours, metabolic disorders, and cardiopulmonary disorders can all cause delirium.

Question 11

Microscopic-level traumatic brain injuries include:

Accepted Answer

The answer of Microscopic-level traumatic brain injuries include:
...

Question 12

Frontotemporal dementia is the most common form of early onset dementia, accounting for what per cent of all dementia cases before age 65?

Accepted Answer

Frontotemporal dementia accounts for 20-50% of all dementia cases before age 65, making it a significant form of early onset dementia.

Question 13

A number of neurocognitive disorders are caused by specific medical conditions, including:

Accepted Answer

Parkinson's disease is a neurodegenerative disorder that affects movement and can lead to neurocognitive disorders.

Question 14

Mild cognitive impairment progresses to dementia at the rate of approximately 3 to 15 per cent per year. Within 10 years, what percentage of MCI cases will have developed Alzheimer's?

Accepted Answer

Based on the given progression rate of 3-15% per year, within 10 years, an estimated 30-85% of MCI cases will have developed dementia. However, the majority of MCI cases progress to Alzheimer's (60-80% according to some studies), so the most likely percentage range would be 70-80%.

Question 15

As Alzheimer's disease progresses a number of physical changes occur. Which one of the following is not included in the list of changes within the text?

Accepted Answer

Weight gain is not typically associated with Alzheimer's disease progression. Appetite disturbance, difficulty walking, and tremors are often seen as the disease advances.

Question 16

Routine laboratory tests should be performed when determining treatable causes of dementia, including:

Accepted Answer

Fasting glucose is a routine laboratory test that should be performed when determining treatable causes of dementia. This is because diabetes can contribute to cognitive decline and may need to be treated to improve symptoms. Coagulation tests, blood cholesterol tests, and liver function tests are not typically associated with treatable causes of dementia.

Question 17

The clock drawing test can be used to assess a number of cognitive domains. Which one of the following is not included in the list provided by the text?

Accepted Answer

The answer of The clock drawing test can be used...

Question 18

A significant degree of caregiver stress has emerged as a result of government policies that focus on:

Accepted Answer

Deinstitutionalization policies have led to an increase in the number of older adults and individuals with disabilities receiving care in community-based settings, which has placed a significant burden on caregivers. This often leads to increased stress levels among caregivers, as they may not receive adequate support or resources to provide quality care to their loved ones.

Question 19

What is the approximate percentage of Canadian patients currently in long term care with a diagnosis of dementia?

Accepted Answer

Approximately 66% of Canadian patients in long-term care have a diagnosis of dementia, reflecting the significant impact of this condition on the need for long-term care services.

Question 20

Due to behavioural and emotional issues associated with TBI, behavioural and psychosocial interventions are an important adjunct to:

Accepted Answer

Behavioural and emotional issues associated with TBI require rehabilitation programs that focus on physical, occupational, and speech therapy. These programs aim to help individuals regain functional abilities so they can resume their daily living activities. Since behavioural and psychosocial issues are also common with TBI, behavioural interventions to manage emotional and cognitive issues, and therapies to prevent depression, anxiety, and PTSD are essential as an adjunct to physical rehabilitation. These interventions help individuals to cope and adapt to life with TBI, which ultimately improves their overall outcome.
