1. Which statement best describes the pathophysiology of dementia of the Alzheimer type?

• A. There is a genetic predisposition and dysregulation of neurotransmitters.
• B. The dementia is transient and secondary to a physical imbalance or disorder.
• C. Hypoxia and decreased perfusion of select areas of the brain cause tissue damage.
• D. The presence of amyloid plaques is associated with brain tissue destruction.

Correct answer: D

Rationale: In Alzheimer's disease, the accumulation of amyloid plaques in the brain is a hallmark feature. These plaques are associated with the destruction of brain tissue, contributing to the cognitive decline seen in dementia. Genetic predisposition and dysregulation of neurotransmitters are factors linked to the development of Alzheimer's disease, but the primary pathology lies in the amyloid plaques. Transient dementia is not characteristic of Alzheimer's disease, which is a progressive neurodegenerative disorder. Hypoxia and decreased perfusion are more typical of vascular dementia, where blood flow to the brain is compromised.

2. Which source of stress would the nurse anticipate in a 5-year-old client?

• A. Jealousy
• B. Stubbornness
• C. Procrastination
• D. Companionship

Correct answer: C

Rationale: Procrastination, which refers to delaying completing chores or activities, is a common source of stress for 5-year-old clients. At this age, children may start experiencing stress related to the pressure of tasks or expectations. Jealousy and stubbornness are more typical sources of stress for 3- and 4-year-old clients who are still developing social and emotional skills. Companionship, on the other hand, is generally seen as a positive aspect in a child's life and is not typically a source of stress but rather a source of support and comfort.

3. Which serum laboratory value should the nurse monitor carefully for a client who has a nasogastric (NG) tube to suction for the past week?

• A. White blood cell count
• B. Albumin
• C. Calcium
• D. Sodium

Correct answer: D

Rationale: The nurse should monitor the client's serum sodium levels carefully when they have been on nasogastric (NG) tube suction for an extended period. Prolonged NG suctioning can lead to fluid loss and subsequent hyponatremia. Monitoring sodium levels is crucial to prevent complications. White blood cell count (Option A), albumin (Option B), and calcium (Option C) are not typically affected by prolonged NG suctioning. Therefore, these values are not the priority for monitoring in this situation.

4. By rolling contaminated gloves inside-out, the nurse is affecting which step in the chain of infection?

• A. Mode of transmission
• B. Portal of entry
• C. Reservoir
• D. Portal of exit

Correct answer: A

Rationale: When the nurse rolls contaminated gloves inside-out, they are manipulating the mode of transmission in the chain of infection. The gloves, which are contaminated, act as a vehicle for transferring pathogens from the reservoir's portal of exit to a potential portal of entry. Choices B, C, and D are incorrect because the action of rolling contaminated gloves does not directly relate to the portal of entry, reservoir, or portal of exit in the chain of infection.

5. A female client with frequent urinary tract infections (UTIs) asks the nurse to explain her friend's advice about drinking a glass of juice daily to prevent future UTIs. Which response is best for the nurse to provide?

• A. Orange juice has vitamin C that deters bacterial growth.
• B. Apple juice is the most useful in acidifying the urine.
• C. Cranberry juice stops pathogens' adherence to the bladder.
• D. Grapefruit juice increases absorption of most antibiotics.

Correct answer: C

Rationale: The correct answer is 'Cranberry juice stops pathogens' adherence to the bladder.' Cranberry juice maintains urinary tract health by reducing the adherence of Escherichia coli bacteria to cells within the bladder. This helps prevent UTIs. Options A, B, and D are incorrect because orange juice with vitamin C, apple juice for urine acidification, and grapefruit juice for antibiotic absorption do not have the same proven effectiveness in preventing UTIs as cranberry juice does.
