Nursing Elites

1. Although stress exposure initiates integrated responses by multiple systems, which system first activates the most important changes?

• A. Pulmonary
• B. Gastrointestinal
• C. Neuroendocrine
• D. Cardiovascular

Correct answer: C

Rationale: The correct answer is C, the Neuroendocrine system. When the body is exposed to stress, the neuroendocrine system plays a crucial role in initiating the body's response. This system, particularly through the hypothalamic-pituitary-adrenal axis, triggers a cascade of physiological responses to stress. Choices A, B, and D are incorrect because while other systems like the cardiovascular and gastrointestinal systems also respond to stress, the neuroendocrine system is primarily responsible for the initial and significant changes in the body's stress response.

2. A 35-year-old male has enlarged lymph nodes in the neck and a mediastinal mass. He was diagnosed with Hodgkin lymphoma. Which of the following abnormal cells would the nurse expect to find with this disease?

• A. Merkel cell
• B. Schwann cell
• C. Reed-Sternberg cell
• D. Kupffer cell

Correct answer: C

Rationale: Reed-Sternberg cells are characteristic of Hodgkin lymphoma. These large abnormal cells have a bi-lobed or multi-lobed nucleus and are essential for diagnosing Hodgkin lymphoma through histological examination. Merkel cells are associated with Merkel cell carcinoma, Schwann cells are related to nerve sheaths, and Kupffer cells are liver macrophages. Therefore, choices A, B, and D are incorrect for Hodgkin lymphoma.

3. A 37-year-old woman has a 10 pack-year smoking history and has been using oral contraceptives for the past 2 years. The nurse should plan health education interventions knowing that this patient faces an increased risk of

• A. osteoporosis.
• B. dementia.
• C. myocardial infarction.
• D. deep vein thrombosis.

Correct answer: C

Rationale: The correct answer is C: myocardial infarction. Women aged 35 and older who smoke, especially with a history of 10 pack-years like in this case, face an increased risk of cardiovascular disorders, including myocardial infarction, when using oral contraceptives. Choice A, osteoporosis, is incorrect because smoking and oral contraceptives do not significantly increase the risk of osteoporosis. Choice B, dementia, is not directly associated with smoking, oral contraceptives, or their combination. Choice D, deep vein thrombosis, is a risk associated with oral contraceptives, especially in combination with smoking, but the highest increased risk in this case is for myocardial infarction.

4. Which pathophysiologic process causes the decreased glomerular filtration rate in a patient with acute glomerulonephritis?

• A. Decreased renal-induced constriction of the renal arteries
• B. Immune complex deposition, increased capillary permeability, and cellular proliferation
• C. Necrosis of 70% or more of the nephrons secondary to increased kidney interstitial hydrostatic pressure
• D. Scar tissue formation throughout the proximal convoluted tubule secondary to toxin-induced collagen synthesis

Correct answer: B

Rationale: The correct answer is B: Immune complex deposition, increased capillary permeability, and cellular proliferation. In acute glomerulonephritis, immune complexes deposit in the glomerulus, leading to inflammation, increased capillary permeability, and cellular proliferation. These processes collectively reduce the glomerular filtration rate. Choices A, C, and D do not accurately describe the pathophysiologic process in acute glomerulonephritis. Decreased renal-induced constriction of the renal arteries, necrosis of nephrons due to increased kidney interstitial hydrostatic pressure, and scar tissue formation in the proximal convoluted tubule are not the primary mechanisms responsible for the decreased filtration rate in this condition.

5. A client has been admitted to the hospital with symptoms of Guillain-Barré syndrome. Which aspect of the client's condition would require priority monitoring?

• A. Monitoring oxygen saturation levels
• B. Monitoring for signs of respiratory compromise
• C. Monitoring for changes in consciousness
• D. Monitoring blood pressure closely

Correct answer: B

Rationale: In Guillain-Barré syndrome, respiratory muscle weakness can lead to respiratory compromise, making it crucial to prioritize monitoring for signs of respiratory distress. Monitoring oxygen saturation levels is important but is secondary to assessing for respiratory compromise in this condition. Changes in consciousness and monitoring blood pressure closely are not typically the priority in Guillain-Barré syndrome.
