1. During a flu shot clinic, one of the questions the student nurse asks relates to whether the client has a history of Guillain-Barré syndrome. The client asks, 'What is that?' How should the nursing student reply?

• A. A type of paralysis that affects movement on both sides of the body. It may even involve the respiratory muscles.
• B. Swelling of your arm where you got your flu shot and maybe your eyes and lips had some swelling as well.
• C. A degenerative disease where you have trouble walking without the help of a cane or walker.
• D. Influenza-like illness where you had fever and chills for 2 to 3 days after your last flu shot.

Correct answer: A

Rationale: The correct answer is A because Guillain-Barré syndrome is an acute immune-mediated polyneuropathy that can lead to paralysis affecting movement on both sides of the body, and in severe cases, involving the respiratory muscles. Choice B is incorrect as it describes local swelling, not the systemic effects of Guillain-Barré syndrome. Choice C is incorrect as it describes a degenerative disease affecting mobility, not an acute immune-mediated condition like Guillain-Barré syndrome. Choice D is incorrect as it describes flu-like symptoms following a flu shot, which is not the same as Guillain-Barré syndrome.

2. While in an induced coma for 3 weeks, a badly burned firefighter awakens and thanks his son for singing Happy Birthday to him a week earlier. Which part of the brain is responsible for allowing him to hear and comprehend while comatose?

• A. Cerebellum
• B. Thalamus
• C. Temporal lobe
• D. Occipital lobe

Correct answer: C

Rationale: The temporal lobe is responsible for processing auditory information, allowing the patient to hear and comprehend while in a coma. The cerebellum is primarily associated with coordination and balance, not auditory processing. The thalamus serves as a relay station for sensory information but is not specifically responsible for auditory processing. The occipital lobe is mainly involved in processing visual information, not auditory functions.

3. What is the cause of swelling during acute inflammation?

• A. Collagenase
• B. Fluid exudate
• C. Lymphocytic margination
• D. Anaerobic glycolysis

Correct answer: B

Rationale: Swelling during acute inflammation is primarily caused by the accumulation of fluid exudate in the affected tissues. This fluid exudate contains proteins and cells that leak from blood vessels due to increased vascular permeability. Collagenase (Choice A) is an enzyme that breaks down collagen and is not directly responsible for swelling. Lymphocytic margination (Choice C) is the process where white blood cells line up along the blood vessel walls, which does not directly cause swelling. Anaerobic glycolysis (Choice D) is a metabolic process that occurs in the absence of oxygen and is not related to the mechanism of swelling in acute inflammation.

4. What is a cause of the crystallization within the synovial fluid of the joint affected by gouty arthritis?

• A. Destruction of proteoglycans
• B. Underexcretion of uric acid
• C. Overexcretion of uric acid
• D. Increased absorption of uric acid

Correct answer: B

Rationale: The correct answer is B: Underexcretion of uric acid. In gouty arthritis, the crystallization within the synovial fluid of the affected joint is caused by the underexcretion of uric acid, leading to the accumulation and subsequent crystallization of urate crystals. Choice A, destruction of proteoglycans, is incorrect as it is not directly related to the crystallization process in gouty arthritis. Choice C, overexcretion of uric acid, is incorrect because gout is primarily associated with underexcretion or decreased excretion of uric acid rather than overexcretion. Choice D, increased absorption of uric acid, is also incorrect as the primary issue in gouty arthritis is the body's inability to properly eliminate uric acid.

5. A 70-year-old woman has difficulty with driving, and she has been frequently getting lost. Her husband said she has also been acting strange and seems to want to sleep a lot. He said the other night she kept saying she was seeing animals such as lions in her room. He says her memory is not too bad, but he is very concerned about her health. Physical examination reveals an alert woman with stable vital signs. Bradykinesia and limb rigidity are noted. These findings are consistent with:

• A. Alzheimer's disease.
• B. Vascular dementia.
• C. Dementia with Lewy bodies.
• D. Frontotemporal dementia.

Correct answer: C

Rationale: The symptoms described in the scenario, such as visual hallucinations, fluctuations in cognition, and parkinsonism (bradykinesia and limb rigidity), are classic features of dementia with Lewy bodies (DLB). DLB is characterized by the presence of Lewy bodies in the brain, which are abnormal protein deposits. Alzheimer's disease (Choice A) typically presents with memory loss as a predominant symptom, which is not a major concern in this case. Vascular dementia (Choice B) is associated with a history of cerebrovascular disease and is not supported by the symptoms described. Frontotemporal dementia (Choice D) usually presents with changes in behavior and personality, rather than the symptoms described in the scenario.
