ATI Pathophysiology Final Exam

1. A 50-year-old female was diagnosed with sideroblastic anemia. Which of the following assessment findings would most likely occur?

A. Bronze-colored skin
B. Decreased iron
C. Normochromic erythrocytes
D. Aplastic bone marrow

Correct answer: A

Rationale: The correct answer is A: 'Bronze-colored skin.' Sideroblastic anemia is characterized by excess iron deposition, leading to bronze-colored skin. This occurs due to the abnormal accumulation of iron in tissues. Choices B, C, and D are incorrect because sideroblastic anemia does not typically present with decreased iron levels, normochromic erythrocytes, or aplastic bone marrow.

2. 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.

3. A patient is starting on alendronate (Fosamax) for the treatment of osteoporosis. What instructions should the nurse provide to ensure the effectiveness of the medication?

A. Take the medication with a full glass of water and remain upright for at least 30 minutes.
B. Take the medication with milk to enhance calcium absorption.
C. Take the medication at bedtime to ensure absorption during sleep.
D. Take the medication with food to prevent nausea.

Correct answer: A

Rationale: The correct answer is A. Alendronate should be taken with a full glass of water, and patients should remain upright for at least 30 minutes to prevent esophageal irritation and ensure proper absorption. Taking the medication with milk (choice B) is not recommended as it may interfere with alendronate absorption. Taking it at bedtime (choice C) is not necessary and may increase the risk of esophageal irritation. Taking the medication with food (choice D) can reduce its absorption and effectiveness.

4. A patient with breast cancer is prescribed tamoxifen (Nolvadex). What key point should the nurse include in the patient education?

A. Tamoxifen may increase the risk of venous thromboembolism.
B. Tamoxifen may cause hot flashes and other menopausal symptoms.
C. Tamoxifen may cause weight gain and fluid retention.
D. Tamoxifen may decrease the risk of osteoporosis.

Correct answer: A

Rationale: The correct answer is A: "Tamoxifen may increase the risk of venous thromboembolism." It is crucial for patients to be aware of the signs and symptoms of blood clots while taking tamoxifen. Choice B is incorrect because hot flashes and menopausal symptoms are common side effects of tamoxifen, but they are not the key point to emphasize. Choice C is incorrect as weight gain and fluid retention are potential side effects of tamoxifen but not the key point for patient education. Choice D is incorrect as tamoxifen does not decrease the risk of osteoporosis; in fact, it may increase the risk of bone loss.

5. What lab results would be noted in a client with leukocytosis?

A. Increased white blood cell count
B. Increased platelet count
C. Decreased white blood cell count
D. Decreased platelet count

Correct answer: A

Rationale: Leukocytosis is a condition characterized by an elevated white blood cell count, typically in response to infection or inflammation. Therefore, the correct answer is an increased white blood cell count (Choice A). Increased platelet count (Choice B) is not a typical finding in leukocytosis. Choices C and D, decreased white blood cell count and decreased platelet count respectively, are opposite to what would be expected in leukocytosis and are therefore incorrect.
