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. A patient with a new diagnosis of diabetes insipidus is planning care. What should be included in the plan of care?

• A. Avoid alcohol
• B. Increase exercise to reduce stress
• C. Increase fluid intake
• D. Restrict sodium intake

Correct answer: A

Rationale: The correct answer is to avoid alcohol. In diabetes insipidus, excessive urination leads to fluid loss, so it is essential to avoid alcohol which can exacerbate dehydration. Choice B is incorrect as increasing exercise may not directly impact diabetes insipidus. Choice C is also incorrect because although increasing fluid intake may seem intuitive, it is not the primary concern in managing diabetes insipidus. Choice D is not directly related to managing diabetes insipidus; sodium restriction is more relevant in conditions like hypertension or heart failure.

3. What intervention should be done if continuous bubbling is seen in the chest tube water seal chamber?

• A. Tighten the connections of the chest tube system
• B. Replace the chest tube system
• C. Clamp the chest tube
• D. Continue monitoring the chest tube

Correct answer: A

Rationale: When continuous bubbling is observed in the chest tube water seal chamber, the appropriate intervention is to tighten the connections of the chest tube system. This step helps address an air leak in the system, which could compromise its effectiveness. Choice B (Replace the chest tube system) is not the initial step and may be unnecessary if the issue can be resolved by tightening connections. Choice C (Clamp the chest tube) is incorrect as clamping the chest tube could lead to a dangerous increase in pressure within the system. Choice D (Continue monitoring the chest tube) is also not the best immediate action to take when continuous bubbling is present, as prompt intervention is needed to prevent complications.

4. What are the early signs of hypokalemia on an ECG?

• A. Flattened T waves
• B. Elevated ST segments
• C. Prominent U waves
• D. Widened QRS complex

Correct answer: A

Rationale: Flattened T waves are an early sign of hypokalemia on an ECG. In hypokalemia, the T waves may flatten and eventually invert. Elevated ST segments are not typically associated with hypokalemia. Prominent U waves are seen in conditions like hypokalemia, but they are not considered an early sign. A widened QRS complex is more commonly associated with hyperkalemia rather than hypokalemia.

5. A nurse in an emergency department is caring for a client who has sustained multiple injuries. The nurse observes the client's thorax moving inward during inspiration and outward during expiration. The nurse should suspect which of the following injuries?

• A. Flail chest
• B. Hemothorax
• C. Pulmonary contusion
• D. Pneumothorax

Correct answer: A

Rationale: The correct answer is A: Flail chest. Flail chest results from multiple rib fractures, causing paradoxical chest movement where the injured part moves inward during inspiration and outward during expiration, interfering with ventilation. Choice B, Hemothorax, involves blood in the pleural cavity and does not typically cause paradoxical chest movement. Choice C, Pulmonary contusion, is a bruise to the lung tissue and does not present with paradoxical chest movement. Choice D, Pneumothorax, is the presence of air in the pleural space, leading to lung collapse, but it does not demonstrate paradoxical chest movement like in flail chest.
