1. What is an escharotomy and why is it performed?

• A. A surgical incision made to improve circulation in burn injuries
• B. A procedure to remove dead tissue from a wound
• C. A procedure to remove excess fluid from the lungs
• D. A procedure to relieve pain from burns

Correct answer: A

Rationale: An escharotomy is a surgical procedure involving an incision through the eschar (dead tissue) to relieve pressure in burn injuries. It is performed to improve circulation to the affected area, prevent further damage, and restore blood flow. Choice B is incorrect because an escharotomy is not primarily focused on removing dead tissue but rather on relieving pressure. Choice C is incorrect as it describes a procedure related to pulmonary issues, not burn injuries. Choice D is incorrect because while pain relief may be a result of an escharotomy, it is not the primary purpose of the procedure.

2. What should be taught to a patient following cataract surgery?

• A. Avoid NSAIDs
• B. Wear dark glasses when outdoors
• C. Report green or yellow drainage immediately
• D. Itching is normal unless accompanied by pain and nausea

Correct answer: A

Rationale: The correct answer is to avoid NSAIDs after cataract surgery to reduce the risk of bleeding. Choice B, wearing dark glasses when outdoors, is generally recommended after cataract surgery to protect the eyes from bright sunlight, but it is not the most critical instruction. Choice C, reporting green or yellow drainage immediately, is important to monitor for signs of infection, but it is not specific to cataract surgery. Choice D, itching is normal unless accompanied by pain and nausea, is not the most crucial advice post-cataract surgery. Therefore, the key instruction is to avoid NSAIDs to minimize bleeding risk.

3. What ECG change is associated with hyperkalemia?

• A. Flattened T waves
• B. ST depression
• C. Prominent U waves
• D. Elevated ST segments

Correct answer: B

Rationale: The correct ECG change associated with hyperkalemia is ST depression. Hyperkalemia typically presents with ECG changes such as peaked T waves, prolonged PR interval, widened QRS complex, and finally, ST segment depression. Flattened T waves are more commonly associated with hypokalemia. Prominent U waves are seen in hypokalemia as well. Elevated ST segments are not a typical ECG finding in hyperkalemia.

4. A nurse is providing discharge teaching to a client following a heart transplant. Which of the following information should the nurse include in the teaching?

• A. Immunosuppressant medications need to be taken for up to 1 year
• B. Shortness of breath might be an indication of transplant rejection
• C. The surgical site will heal in 3 to 4 weeks after surgery
• D. Begin 45 minutes of moderate aerobic exercise per day following discharge

Correct answer: B

Rationale: The correct answer is B. Shortness of breath is an important sign of transplant rejection. Other manifestations of rejection include fatigue, edema, bradycardia, and hypotension. Choices A, C, and D are incorrect because: A) Immunosuppressant medications are typically required for life, not just up to 1 year. C) The surgical site healing time can vary and may take longer than 3 to 4 weeks. D) Starting a specific exercise regimen should be individualized and guided by healthcare providers; a general recommendation like 45 minutes of exercise per day may not be suitable for all heart transplant recipients.

5. What are the expected findings in a patient experiencing hypokalemia?

• A. Flattened T waves on an ECG
• B. Elevated ST segments
• C. Prominent U waves
• D. Bradycardia

Correct answer: A

Rationale: The correct answer is A: Flattened T waves on an ECG. Hypokalemia is characterized by flattened T waves on an ECG, which is an early indicator of low potassium levels. Elevated ST segments (Choice B) are associated with conditions like myocardial infarction, not hypokalemia. Prominent U waves (Choice C) are typically seen in hypokalemia, but flattened T waves are more specific. Bradycardia (Choice D) can be a manifestation of severe hypokalemia but is not as specific as flattened T waves on an ECG.
