Pathophysiology Exam 1 Quizlet
1. A client with a history of smoking presents with a chronic cough and shortness of breath. The nurse should suspect which condition?
- A. Pulmonary fibrosis
- B. Chronic obstructive pulmonary disease (COPD)
- C. Lung cancer
- D. Pulmonary edema
Correct answer: B
Rationale: The correct answer is B: Chronic obstructive pulmonary disease (COPD). COPD is often associated with a chronic cough and shortness of breath, especially in individuals with a history of smoking. Pulmonary fibrosis (choice A) typically presents with progressive dyspnea and dry cough. Lung cancer (choice C) may present with a chronic cough, shortness of breath, and other symptoms like weight loss and hemoptysis. Pulmonary edema (choice D) presents with symptoms such as acute shortness of breath, orthopnea, and pink, frothy sputum.
2. What is the characteristic of the condition of leukemia?
- A. A benign growth of skin cells
- B. A malignant growth of skin cells
- C. A malignant growth of white blood cells
- D. A benign growth of white blood cells
Correct answer: C
Rationale: The correct answer is C: 'A malignant growth of white blood cells.' Leukemia is a type of cancer that affects the blood and bone marrow, leading to an overproduction of abnormal white blood cells. These cells are malignant and impair the normal function of healthy blood cells. Choices A, B, and D are incorrect because leukemia does not involve skin cells or benign growths; instead, it specifically refers to the abnormal proliferation of white blood cells.
3. What specific instructions should the nurse provide to ensure proper administration of alendronate (Fosamax) for the treatment of osteoporosis?
- A. Take the medication with a full glass of water and remain upright for at least 30 minutes.
- B. Take the medication at bedtime to ensure absorption during sleep.
- C. Take the medication with milk to enhance calcium absorption.
- D. Take the medication with food to prevent gastrointestinal upset.
Correct answer: A
Rationale: The correct answer is to take the medication with a full glass of water and remain upright for at least 30 minutes. This is important to prevent esophageal irritation and ensure proper absorption. Choice B is incorrect because alendronate should be taken in the morning on an empty stomach, at least 30 minutes before eating or drinking anything other than water. Choice C is incorrect because alendronate should not be taken with milk as it can interfere with its absorption. Choice D is incorrect because alendronate should be taken on an empty stomach, not with food.
4. A 30-year-old has poorly controlled asthma and is taking prednisone 10 mg by mouth once a day. He has been on this regimen for 6 weeks. Abrupt withdrawal or discontinuation of this medication can cause:
- A. adrenal crisis
- B. hypercortisolism
- C. ACTH stimulation
- D. thyroid crisis
Correct answer: A
Rationale: Abrupt withdrawal or discontinuation of prednisone, a corticosteroid, can lead to adrenal crisis. This occurs due to the suppression of the adrenal glands' natural cortisol production caused by prolonged exogenous steroid administration. Adrenal crisis presents with symptoms such as weakness, fatigue, abdominal pain, and hypotension. Hypercortisolism (Cushing syndrome) results from chronic excessive exposure to cortisol, not abrupt withdrawal. ACTH stimulation would be expected in response to low cortisol levels, not as a direct consequence of prednisone withdrawal. Thyroid crisis (thyroid storm) is associated with severe hyperthyroidism and is not directly related to corticosteroid withdrawal.
5. A 20-year-old male shoots his hand with a nail gun while replacing roofing shingles. Which of the following cell types would be the first to aid in killing bacteria to prevent infection in his hand?
- A. Eosinophils
- B. Neutrophils
- C. Leukotrienes
- D. Monocytes
Correct answer: B
Rationale: Neutrophils are the first responders to bacterial infections. When there is a breach in the skin like in this scenario, neutrophils are quickly recruited to the site of injury to phagocytize and kill bacteria. Eosinophils are primarily involved in parasitic infections and allergic reactions, making choice A incorrect. Leukotrienes are lipid mediators involved in inflammation but are not cells, so choice C is incorrect. Monocytes are precursors to macrophages and play a role in immune response, but they are not the first cells to arrive at the site of a bacterial infection, making choice D incorrect.
