1. What is the purpose of an escharotomy?

• A. To relieve pressure and improve circulation in burn injuries
• B. To reduce pain in the affected area
• C. To remove necrotic tissue from a wound
• D. To prevent infection from spreading

Correct answer: A

Rationale: An escharotomy is performed to relieve pressure and improve circulation in areas affected by deep burns. This procedure helps prevent complications such as compartment syndrome by releasing the constricting eschar. Choice B is incorrect because while pain relief may be a secondary outcome of the procedure, the primary purpose is to address pressure and circulation issues. Choice C is incorrect as an escharotomy specifically focuses on releasing pressure, not removing necrotic tissue. Choice D is incorrect as the primary goal of an escharotomy is not to prevent infection but rather to address the immediate issues related to deep burn injuries.

2. What symptoms are expected in a patient with compartment syndrome?

• A. Unrelieved pain, pallor, and pulselessness
• B. Localized swelling and numbness
• C. Fever and infection
• D. Weakness and fatigue

Correct answer: A

Rationale: In a patient with compartment syndrome, the key symptoms include unrelieved pain, pallor, and pulselessness. These symptoms indicate reduced circulation in the affected compartment. Choice B is incorrect as localized swelling and numbness are not typically associated with compartment syndrome. Choice C is incorrect as fever and infection are not primary symptoms of compartment syndrome. Choice D is incorrect as weakness and fatigue are not typically seen in compartment syndrome.

3. What are the expected changes on an ECG for a patient with hypokalemia?

• A. Flattened T waves
• B. Prominent U waves
• C. ST elevation
• D. Wide QRS complexes

Correct answer: A

Rationale: Flattened T waves are an early sign of hypokalemia on an ECG. Hypokalemia primarily manifests as flattened T waves on an ECG. While prominent U waves can be seen in hypokalemia, they are not as specific as flattened T waves. ST elevation is more commonly associated with conditions like myocardial infarction rather than hypokalemia. Wide QRS complexes are typically not a feature of hypokalemia on an ECG.

4. A nurse is caring for a client who has a traumatic brain injury. Which of the following findings should indicate to the nurse the need for immediate intervention?

• A. Axillary temperature 37.2°C (99°F)
• B. Apical pulse 100/min
• C. Respiratory rate 30/min
• D. Blood pressure 140/84 mm Hg

Correct answer: C

Rationale: The correct answer is C. The nurse should prioritize airway and breathing in a client with a traumatic brain injury. An increased respiratory rate may indicate CO2 retention, which could lead to increased intracranial pressure. Choice A, axillary temperature 37.2°C (99°F), is within normal range and does not indicate an immediate need for intervention. Choice B, apical pulse 100/min, is slightly elevated but not as critical as respiratory distress in this scenario. Choice D, blood pressure 140/84 mm Hg, is also within normal limits and does not require immediate intervention compared to the respiratory rate.

5. What are the expected signs in a patient with compartment syndrome?

• A. Unrelieved pain, pallor, and pulselessness
• B. Fever and infection
• C. Localized redness and swelling
• D. Loss of sensation in the affected area

Correct answer: A

Rationale: In a patient with compartment syndrome, the classic signs include unrelieved pain, pallor, and pulselessness. These signs indicate compromised circulation and neurovascular function in the affected compartment. Fever and infection (Choice B) are not typical signs of compartment syndrome. Localized redness and swelling (Choice C) can be seen in other conditions like cellulitis but are not specific to compartment syndrome. Loss of sensation in the affected area (Choice D) may occur in some cases but is not as specific or consistent as unrelieved pain, pallor, and pulselessness in diagnosing compartment syndrome.
