Medical Surgical Assignment Exam HESI
1. A client who is experiencing respiratory distress is admitted with respiratory acidosis. Which pathophysiological process supports the client’s respiratory acidosis?
- A. Low oxygen levels are present in the blood.
- B. High levels of carbon dioxide have accumulated in the blood.
- C. Increased bicarbonate levels are causing alkalosis.
- D. Respiratory rate is increased, causing hyperventilation.
Correct answer: B
Rationale: High levels of carbon dioxide in the blood lead to respiratory acidosis due to inadequate ventilation. The correct answer is B. In respiratory acidosis, the accumulation of carbon dioxide in the blood occurs due to inadequate exhalation, leading to acidosis. Choice A is incorrect as low oxygen levels are related to hypoxemia, not respiratory acidosis. Choice C is incorrect as increased bicarbonate levels would lead to alkalosis, not acidosis. Choice D is incorrect as an increased respiratory rate causing hyperventilation would actually help decrease carbon dioxide levels, not lead to respiratory acidosis.
2. A client who is newly diagnosed with emphysema is being prepared for discharge. Which instruction is best for the nurse to provide the client to assist them with dyspnea self-management?
- A. Allow additional time to complete physical activities to reduce oxygen demand.
- B. Practice inhaling through the nose and exhaling slowly through pursed lips.
- C. Use a humidifier to increase home air quality humidity between 30-50%.
- D. Strengthen abdominal muscles by alternating leg raises during exhalation.
Correct answer: B
Rationale: The correct answer is B. Instructing the client to practice inhaling through the nose and exhaling slowly through pursed lips can help improve oxygenation and reduce dyspnea. This technique, known as pursed lip breathing, can help regulate breathing patterns and decrease the work of breathing in clients with emphysema. Choice A is incorrect because allowing additional time for physical activities does not directly address dyspnea management. Choice C is incorrect as using a humidifier, although beneficial for respiratory conditions, does not specifically assist with dyspnea self-management. Choice D is also incorrect as strengthening abdominal muscles through leg raises does not directly target dyspnea relief.
3. Twelve hours following a unilateral total knee replacement, a client reports being unable to sleep because of severe incisional pain. What is the best initial nursing action?
- A. Administer a prescribed sedative.
- B. Reposition the client for comfort.
- C. Apply ice packs to the surgical site.
- D. Instruct the client in the use of the prescribed patient-controlled analgesia (PCA) pump.
Correct answer: D
Rationale: Instructing the client in the use of the PCA pump is the best initial nursing action for managing severe incisional pain after knee replacement surgery. The PCA pump allows the client to self-administer pain medication effectively, promoting better pain management. Administering a sedative may mask the pain temporarily but doesn't address the root cause. Repositioning the client for comfort or applying ice packs may provide some relief but doesn't address the need for effective pain control as the PCA pump does.
4. A client with hypertension is prescribed a low-sodium diet. Which food should the client avoid?
- A. Fresh fruits
- B. Processed cheese
- C. Whole grain bread
- D. Fresh vegetables
Correct answer: B
Rationale: The correct answer is B: Processed cheese. Processed cheese is high in sodium and should be avoided in a low-sodium diet for clients with hypertension. Fresh fruits, whole grain bread, and fresh vegetables are generally low in sodium and can be part of a healthy diet for clients with hypertension.
5. Methotrexate is prescribed for a client with rheumatoid arthritis (RA) who is also taking aspirin. What is the best explanation for the nurse to provide as to why a second medication has been added?
- A. Methotrexate slows the disease progression while aspirin controls the symptoms.
- B. Methotrexate helps to reduce the side effects of aspirin.
- C. Methotrexate has fewer harmful side effects than aspirin.
- D. Methotrexate enhances the effect of aspirin.
Correct answer: A
Rationale: The correct answer is A. Methotrexate is a disease-modifying antirheumatic drug (DMARD) that slows the progression of rheumatoid arthritis (RA), while aspirin helps control symptoms such as pain and inflammation. Therefore, the combination of methotrexate and aspirin is beneficial in managing RA by addressing both disease progression and symptom control. Choices B, C, and D are incorrect because methotrexate is not added to reduce the side effects of aspirin, has different side effects compared to aspirin, and does not enhance the effect of aspirin.
