Nursing Elites

1. A patient has acute respiratory failure (ARF). Which of the following would the nurse expect to find?

• A. Alkalosis and hyperventilation
• B. Hypoxemia and hypercapnia
• C. Alkalosis and high potassium
• D. Elevated sodium and acidosis

Correct answer: B

Rationale: In acute respiratory failure, hypoxemia (low blood oxygen) and hypercapnia (high blood carbon dioxide) are commonly observed. Choice A is incorrect because alkalosis (high pH) and hyperventilation are not typically seen in acute respiratory failure. Choice C is incorrect as it mentions alkalosis and high potassium, which are not characteristic of acute respiratory failure. Choice D is also incorrect because elevated sodium and acidosis are not typically associated with acute respiratory failure.

2. What property is found in clients with metastatic cancer?

• A. Tumors that are well encapsulated
• B. Tumors with slow, stable growth
• C. Cells that are genetically stable
• D. Cells invading local tissue and overrunning neighboring cells

Correct answer: D

Rationale: Metastatic cancer is characterized by cells that invade local tissue and overrun neighboring cells. Therefore, the correct answer is D. Choices A, B, and C are incorrect because metastatic cancer is associated with aggressive behavior where cells invade and spread to other parts of the body, rather than being well encapsulated, growing slowly, or being genetically stable.

3. Which term should the nurse use to document a situation in which cells increase in size and function?

• A. Atrophy
• B. Hypertrophy
• C. Metaplasia
• D. Hyperplasia

Correct answer: B

Rationale: Hypertrophy is the correct term used to describe the situation in which cells increase in size and function. Atrophy (Choice A) is the opposite, indicating a decrease in cell size. Metaplasia (Choice C) refers to the reversible replacement of one mature cell type by another. Hyperplasia (Choice D) involves an increase in the number of cells, not just an increase in size and function as in hypertrophy.

4. A patient is being educated on the administration of tinidazole (Tindamax). Which of the following indicates that the patient understands the administration of tinidazole?

• A. “I will report to the doctor if I have a slow heart rate.”
• B. “The medicine will leave a bitter or metallic taste in my mouth.”
• C. “I will report urinary urgency and incontinence.”
• D. “The medication is given in two doses every day.”

Correct answer: B

Rationale: The correct answer is B. Tinidazole (Tindamax) is known to cause a bitter or metallic taste in the mouth. This side effect is common and indicates that the patient understands the medication they are taking. Choices A, C, and D are incorrect because they do not specifically relate to the common side effects or administration details of tinidazole.

5. When a patient asks the nurse what hypersensitivity is, how should the nurse respond? Hypersensitivity is best defined as:

• A. A reduced immune response found in most pathologic states
• B. A normal immune response to an infectious agent
• C. An excessive or inappropriate response of the immune system to a sensitizing antigen
• D. Antigenic desensitization

Correct answer: C

Rationale: Hypersensitivity is correctly defined as an excessive or inappropriate response of the immune system to a sensitizing antigen. This response leads to tissue damage or other clinical manifestations. Choice A is incorrect as hypersensitivity involves an exaggerated, not a reduced, immune response. Choice B is incorrect because hypersensitivity is not a normal immune response to an infectious agent but rather an exaggerated one. Choice D is incorrect as it refers to desensitization, which is the opposite of hypersensitivity.
