ATI Pathophysiology Exam
1. How should rifampin most likely be administered to a patient diagnosed with tuberculosis?
- A. Orally, with food
- B. Orally, on an empty stomach
- C. Intramuscularly
- D. Intravenously, as a bolus
Correct answer: A
Rationale: Rifampin is typically administered orally, and it is recommended to be taken with food to enhance its absorption and reduce gastrointestinal side effects. Administering rifampin intramuscularly or intravenously is not the standard route of administration for this medication used in tuberculosis treatment.
2. A 50-year-old woman has had a relapse of her multiple sclerosis (MS) after several years of being symptom-free. Which of the following factors is most likely to have contributed to her relapse?
- A. Emotional stress
- B. Dietary indiscretion
- C. Physical overexertion
- D. Adequate rest and relaxation
Correct answer: C
Rationale: The correct answer is C: Physical overexertion. In individuals with multiple sclerosis (MS), physical overexertion can exacerbate symptoms and contribute to a relapse. It is important for individuals with MS to balance physical activity to avoid triggering symptom reoccurrence. Choices A, B, and D are less likely to have directly contributed to the relapse. Emotional stress and dietary indiscretion may play a role in exacerbating symptoms in some individuals, but physical overexertion is more commonly associated with MS relapses. Adequate rest and relaxation are important for overall well-being but are not typically linked to MS relapses.
3. 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.
4. Which of the following are characteristic, localized cardinal signs of acute inflammation? (Select ONE that does not apply.)
- A. Redness
- B. Fatigue
- C. Swelling
- D. Warmth
Correct answer: B
Rationale: The correct answers are A, C, and D. Redness, swelling, and warmth are classic signs of acute inflammation. Redness occurs due to increased blood flow, swelling is caused by leakage of fluid into tissues, and warmth is due to the vasodilation and increased blood flow in the affected area. Fatigue is not a cardinal sign of acute inflammation and is not directly associated with the inflammatory response.
5. After a patient is exposed to a specific antigen, B cells will differentiate into:
- A. B cytotoxic cells
- B. Plasma cells
- C. Bursal cells
- D. Clonal equivalents
Correct answer: B
Rationale: After exposure to a specific antigen, B cells undergo differentiation into plasma cells. Plasma cells are responsible for producing antibodies in response to the antigen. Choice A ('B cytotoxic cells') is incorrect because B cells do not differentiate into cytotoxic cells; cytotoxic cells are typically associated with T cells. Choice C ('Bursal cells') is incorrect as bursal cells are specific to birds and not relevant to human immune responses. Choice D ('Clonal equivalents') is incorrect as it does not describe the differentiation process of B cells exposed to antigens.
