In Alzheimer's disease, plaques are commonly found in this area of the brain:
-
Hypothalamus
-
Brain stem

A. HippocampusExplanation
The correct answer is hippocampus. In Alzheimer's disease, plaques, which are abnormal clusters of protein fragments, are commonly found in the hippocampus. The hippocampus is a vital region of the brain involved in memory formation and consolidation. Damage to the hippocampus due to the accumulation of plaques is believed to be a major contributor to memory loss and cognitive decline in Alzheimer's disease patients.Rate this question:

The decline in cognitive function is usually progressive and can significantly impact a person's independence and quality of life.Rate this question:

-
Autism
-
Fragile X syndrome
-
Head injury
-
Borderline personality
Correct Answer
A. Fragile X syndromeExplanation
Fragile X syndrome is the correct answer because it is the most common known genetic cause of intellectual disability. It is a genetic condition that causes a range of developmental problems, including learning disabilities and cognitive impairment. Fragile X syndrome is caused by a mutation in the FMR1 gene, which leads to a deficiency in a specific protein that is important for brain development and function. This genetic disorder affects both males and females, but males are typically more severely affected.Rate this question:

A family member expresses concern to a nurse about behavioral changes in an elderly aunt. Which would cause the nurse to suspect a cognitive impairment disorder?
-
Decreased interest in activities that she once enjoyed
-
Fearfulness of being alone at night
-
Increased complaints of physical ailments
-
Problems with preparing a meal or balancing her checkbook
Correct Answer
A. Problems with preparing a meal or balancing her checkbookExplanation
The nurse would suspect a cognitive impairment disorder based on the problems with preparing a meal or balancing her checkbook. This is because difficulty with tasks that require organization, planning, and problem-solving skills can be indicative of cognitive impairments such as dementia or Alzheimer's disease. The other options, such as decreased interest in activities, fearfulness of being alone, and increased complaints of physical ailments, may be indicative of other issues but are not specific to cognitive impairment disorders.Rate this question:
