ATI Pathophysiology Exam 3

1. What is reperfusion injury?

Correct answer: C

Rationale: Reperfusion injury refers to the secondary injury that occurs after blood flow is reestablished following ischemia. This process leads to tissue damage due to the sudden reintroduction of oxygen and nutrients, causing oxidative stress, inflammation, and cell death. Choice A is incorrect as it describes the normal healing process of bone tissue after a fracture. Choice B is incorrect as it describes specific mechanisms related to skin wounds, not reperfusion injury. Choice D is incorrect as it refers to a different concept, which is adverse reactions or complications that can occur after a blood transfusion, not reperfusion injury.

2. What is the characteristic of the condition of leukemia?

Correct answer: C

Rationale: The correct answer is C: 'A malignant growth of white blood cells.' Leukemia is a type of cancer that affects the blood and bone marrow, leading to an overproduction of abnormal white blood cells. These cells are malignant and impair the normal function of healthy blood cells. Choices A, B, and D are incorrect because leukemia does not involve skin cells or benign growths; instead, it specifically refers to the abnormal proliferation of white blood cells.

3. A client with a diagnosis of depression has been prescribed a medication that ultimately increases the levels of the neurotransmitter serotonin between neurons. Which process will accompany the actions of the neurotransmitter in a chemical synapse?

Correct answer: D

Rationale: When serotonin levels increase, more neurotransmitters will cross the synaptic cleft and bind with postsynaptic receptors, facilitating enhanced communication. Option A is incorrect because chemical synapses, unlike electrical synapses, are unidirectional. Option B is incorrect because neurotransmitters impact communication with multiple neurons, not just a single connected neuron. Option C is incorrect because neurotransmitters cross the synaptic cleft, not gap junctions.

4. A 56-year-old woman has been experiencing memory loss and confusion for the past year. The client is diagnosed with Alzheimer's disease. Which finding is most characteristic of this disease?

Correct answer: C

Rationale: The correct answer is C: Accumulation of beta-amyloid plaques. Alzheimer's disease is characterized by the accumulation of beta-amyloid plaques in the brain. These plaques are formed from the buildup of beta-amyloid protein fragments between nerve cells. Choice A, neurofibrillary tangles, are a hallmark of another neurodegenerative disease called Alzheimer's disease. Choice B, demyelination of neurons, is more characteristic of diseases like multiple sclerosis. Choice D, formation of Lewy bodies, is associated with Lewy body dementia, not Alzheimer's disease.

5. Which patient is most likely to be diagnosed with complex regional pain syndrome II (CRPS II)?

Correct answer: D

Rationale: Complex regional pain syndrome II (CRPS II) typically occurs after an injury to a peripheral nerve. In this case, a brachial plexus injury involves damage to the nerves that control muscles in the arm and hand, leading to chronic pain and swelling. Choices A, B, and C describe pain related to other conditions such as spinal cord injury, carpal tunnel surgery, and fracture immobilization, which are not typically associated with CRPS II.
