ATI Pathophysiology Quizlet
1. An older adult patient has just sheared the skin on her elbow while attempting to boost herself up in bed, an event that has precipitated acute inflammation in the region surrounding the wound. Which of the following events will occur during the vascular stage of the patient's inflammation?
- A. Outpouring of exudate into interstitial spaces
- B. Chemotaxis
- C. Accumulation of leukocytes along epithelium
- D. Phagocytosis of cellular debris
Correct answer: A
Rationale: During the vascular stage of inflammation, there is an outpouring of exudate into the interstitial spaces, leading to swelling and edema. Choice B, chemotaxis, occurs during the cellular stage of inflammation, where leukocytes move to the site of injury in response to chemical signals. Choice C, accumulation of leukocytes along the epithelium, is not a typical event during the vascular stage. Phagocytosis of cellular debris, as in choice D, mainly occurs during the resolution stage of inflammation.
2. Which of the following are manifestations of Cushing syndrome?
- A. Truncal obesity with thin extremities.
- B. Enlargement of face, hands, and feet.
- C. Cachexia.
- D. Thick scalp hair.
Correct answer: A
Rationale: Truncal obesity with thin extremities is a classic manifestation of Cushing syndrome due to the redistribution of fat. Enlargement of face, hands, and feet is seen in conditions like acromegaly, not Cushing syndrome. Cachexia is a state of severe weight loss and muscle wasting, typically seen in conditions like cancer or advanced infections. Thick scalp hair is not typically associated with Cushing syndrome.
3. Which ability should Nurse Rebecca expect from a client in the mild stage of dementia of the Alzheimer’s type?
- A. Remembering the daily schedule
- B. Recalling past events
- C. Coping with anxiety
- D. Solving problems of daily living
Correct answer: B
Rationale: In the mild stage of dementia of the Alzheimer’s type, clients can often recall past events but may have difficulty with new information. Therefore, Nurse Rebecca should expect the client to have the ability to recall past events. Choice A is incorrect because remembering the daily schedule may become challenging as the disease progresses. Choice C is incorrect as clients in the mild stage may experience anxiety, but coping with anxiety is not a specific ability associated with this stage of dementia. Choice D is incorrect as solving problems of daily living becomes more challenging as the disease advances, not in the mild stage.
4. Interpret the following arterial blood gas results: PH = 7.30; PaCO2 = 55 mmHg; HCO3 = 24 mEq/L
- A. Respiratory acidosis
- B. Metabolic acidosis
- C. Respiratory alkalosis
- D. Metabolic alkalosis
Correct answer: A
Rationale: The correct answer is A: Respiratory acidosis. In respiratory acidosis, there is an accumulation of CO2 in the blood, leading to a decrease in pH. The elevated PaCO2 of 55 mmHg in the given results indicates hypoventilation, causing respiratory acidosis. Choices B, C, and D are incorrect because the provided data does not show metabolic acidosis, respiratory alkalosis, or metabolic alkalosis.
5. During an assessment of a male client suspected of having a disorder of motor function, which finding would suggest a possible upper motor neuron (UMN) lesion?
- A. Hypotonia
- B. Hyperreflexia
- C. Muscle atrophy
- D. Fasciculations
Correct answer: B
Rationale: Hyperreflexia, or exaggerated reflexes, is a common sign of an upper motor neuron (UMN) lesion. An UMN lesion indicates damage to the central nervous system pathways that control movement. Hypotonia (choice A) refers to reduced muscle tone, which is more indicative of lower motor neuron lesions. Muscle atrophy (choice C) suggests long-standing denervation or disuse of muscles. Fasciculations (choice D) are involuntary muscle contractions that can be seen in lower motor neuron lesions, like in amyotrophic lateral sclerosis (ALS), rather than UMN lesions.
