ATI Pathophysiology Exam 2
1. What causes atherosclerotic plaques to form in the body?
- A. Poor dietary habits
- B. Administration of statin medication
- C. Interruption of blood flow to the brain
- D. Injury to the endothelium of the coronary arteries
Correct answer: D
Rationale: Atherosclerotic plaques form in the body due to injury to the endothelium of the coronary arteries. When the endothelium is damaged, it triggers an inflammatory response that leads to the accumulation of fats, cholesterol, and other substances, forming plaques. These plaques can narrow the arteries, reducing blood flow and potentially leading to serious complications like heart attacks or strokes. Poor dietary habits (choice A) can contribute to the development of atherosclerosis by promoting the buildup of plaque-forming substances in the blood, but the direct cause is the injury to the endothelium. Administration of statin medication (choice B) is actually a treatment for high cholesterol and aims to reduce the risk of plaque formation. Interruption of blood flow to the brain (choice C) is more related to conditions like ischemic stroke rather than the primary cause of atherosclerotic plaque formation.
2. Which of the following is an example of a macro-level health policy?
- A. Local health ordinances
- B. State licensing regulations
- C. National healthcare legislation
- D. Institutional policies
Correct answer: C
Rationale: The correct answer is national healthcare legislation. This type of policy operates at a broad level, influencing healthcare delivery and financing across an entire nation. It sets overarching frameworks and regulations that impact various aspects of the healthcare system on a large scale, affecting a wide population rather than specific localities or institutions. Choices A, B, and D are not examples of macro-level health policy. Local health ordinances pertain to specific areas or communities, state licensing regulations focus on a state level, and institutional policies are internal regulations of a particular healthcare facility.
3. A nurse is planning care for a client who has pneumonia. Which of the following interventions should the nurse include to promote airway clearance?
- A. Encourage the client to increase fluid intake.
- B. Suction the client every 2 hours.
- C. Perform chest physiotherapy every 8 hours.
- D. Administer oxygen via nasal cannula.
Correct answer: A
Rationale: Encouraging the client to increase fluid intake is essential to promote airway clearance in pneumonia. Adequate hydration helps to thin respiratory secretions, making them easier to expectorate. Suctioning every 2 hours may be too frequent and can lead to airway trauma and irritation. Chest physiotherapy is not typically indicated for pneumonia unless there are specific complications. Administering oxygen via nasal cannula may be necessary to maintain oxygen saturation but does not directly promote airway clearance.
4. A client receiving total parenteral nutrition (TPN is awaiting the next container. What fluid should the nurse infuse in the interim?
- A. Dextrose 5% in water
- B. 0.9% sodium chloride
- C. Dextrose 10% in water
- D. Lactated Ringer’s solution
Correct answer: 0.9% sodium chloride
Rationale: The correct answer is 0.9% sodium chloride. When a client receiving TPN is awaiting the next container, infusing 0.9% sodium chloride is the appropriate choice to maintain fluid and electrolyte balance. Dextrose solutions are not recommended as they do not provide sufficient nutrition. Lactated Ringer’s solution contains electrolytes but lacks essential nutrients found in TPN, making it an inadequate choice during the delay in TPN delivery.
5. A client with chronic kidney disease is receiving dietary teaching from a nurse. Which of the following client statements indicates an understanding of the teaching?
- A. I will increase my intake of bananas.
- B. I will limit my intake of foods high in potassium.
- C. I will increase my intake of protein-rich foods.
- D. I will increase my intake of dairy products.
Correct answer: B
Rationale: The correct answer is B. Limiting potassium-rich foods is crucial for clients with chronic kidney disease to prevent hyperkalemia, a common complication. Increasing intake of potassium-rich foods like bananas (choice A), protein-rich foods (choice C), or dairy products (choice D) can exacerbate hyperkalemia in these clients. Bananas, protein-rich foods, and dairy products are all high in potassium, which is detrimental for individuals with chronic kidney disease. Therefore, choices A, C, and D are incorrect.
