ATI Pathophysiology Exam 1
1. A client with chronic obstructive pulmonary disease (COPD) is admitted to the hospital for pneumonia. Which intervention should the nurse prioritize?
- A. Administer bronchodilators as prescribed.
- B. Monitor oxygen saturation levels continuously.
- C. Administer intravenous antibiotics as prescribed.
- D. Provide respiratory therapy treatments as needed.
Correct answer: C
Rationale: Administering IV antibiotics is crucial for treating pneumonia in a client with COPD. Pneumonia is an infection of the lungs that requires prompt antibiotic therapy to prevent complications and improve outcomes. While bronchodilators may help with COPD symptoms, in the case of pneumonia, addressing the infection is the priority. Continuous monitoring of oxygen saturation is important, but administering antibiotics to treat the underlying infection takes precedence. Respiratory therapy treatments can be beneficial, but they are not the initial priority when managing pneumonia in a client with COPD.
2. A secondary immune response differs from the primary immune response in that:
- A. It is more rapid than the primary response and results in higher antibody levels
- B. It is slower than the primary response and doesn't change the antibody levels
- C. It occurs at the same time as the primary response but results in a decrease in antibodies
- D. It only occurs in hyperallergic reactions and results in a decrease in antibodies
Correct answer: A
Rationale: The correct answer is A. A secondary immune response is characterized by being more rapid than the primary response and results in higher antibody levels. This is because memory B cells are already present and can quickly differentiate into plasma cells upon re-exposure to the antigen. Choice B is incorrect because a secondary immune response is faster, not slower, than the primary response, and it does lead to higher antibody levels. Choice C is incorrect because a secondary response does not result in a decrease in antibodies; instead, it leads to an increase. Choice D is incorrect because a secondary immune response is not limited to hyperallergic reactions, and it results in an increase, not a decrease, in antibodies.
3. A client with a pneumothorax is receiving oxygen therapy. Which assessment finding would indicate that the treatment is effective?
- A. Increased respiratory rate
- B. Decreased oxygen saturation levels
- C. Improved breath sounds on the affected side
- D. Increased dyspnea and chest pain
Correct answer: C
Rationale: In a client with a pneumothorax receiving oxygen therapy, improved breath sounds on the affected side would indicate effective treatment. This finding suggests that the collapsed lung is re-expanding, allowing air to flow more freely in and out of the affected area. Choices A, B, and D are incorrect: Increased respiratory rate, decreased oxygen saturation levels, and increased dyspnea and chest pain are signs of ineffective treatment or worsening of the condition in a client with a pneumothorax.
4. After teaching the students about B cells, which statement indicates teaching was successful? B cells are originally derived from cells of the:
- A. Bone marrow
- B. Lymph nodes
- C. Gut-associated lymphoid tissue
- D. Thymus
Correct answer: A
Rationale: The correct answer is A: Bone marrow. B cells are originally derived from cells of the bone marrow. Bone marrow is the primary site where B cells develop and mature. Lymph nodes (choice B), gut-associated lymphoid tissue (choice C), and the thymus (choice D) are involved in the immune response but are not the primary site of origin for B cells.
5. A client with cystic fibrosis is admitted with a pulmonary exacerbation. Which intervention should the nurse prioritize?
- A. Administer a high-calorie, high-protein diet.
- B. Initiate airway clearance techniques.
- C. Encourage the client to maintain an active lifestyle.
- D. Monitor for signs of respiratory distress.
Correct answer: B
Rationale: During a pulmonary exacerbation in cystic fibrosis, the priority intervention is to initiate airway clearance techniques. These techniques help clear mucus from the airways, improving ventilation and reducing the risk of respiratory complications. Administering a high-calorie, high-protein diet is beneficial for overall nutrition but is not the priority during an exacerbation. Encouraging an active lifestyle is important for long-term health but does not address the immediate need for managing exacerbations. Monitoring for signs of respiratory distress is important, but initiating airway clearance techniques takes precedence in the management of pulmonary exacerbations in cystic fibrosis.
