1. A patient with hypokalemia is being monitored. What should the nurse assess for?

A. Muscle weakness
B. Flattened T waves
C. Checking deep tendon reflexes
D. Seizures

Correct answer: A

Rationale: Corrected Question: A patient with hypokalemia is being monitored. What should the nurse assess for? Corrected Choice A: Muscle weakness Corrected Choice B: Flattened T waves Corrected Choice C: Checking deep tendon reflexes Corrected Choice D: Seizures Rationale: Hypokalemia is associated with muscle weakness due to the effect of low potassium levels on muscle function. Flattened T waves on an ECG are characteristic of hypokalemia but are not a direct assessment for the patient's condition. Checking deep tendon reflexes and seizures are not primary symptoms associated with hypokalemia, making them less relevant for monitoring a patient with this electrolyte imbalance.

2. What intervention is needed for a patient with a chest tube and an air leak?

A. Tighten the connections of the chest tube system
B. Replace the chest tube
C. Clamp the chest tube
D. Continue to monitor the chest tube

Correct answer: A

Rationale: The correct intervention for a patient with a chest tube and an air leak is to tighten the connections of the chest tube system. This step helps prevent air leaks and ensures the proper functioning of the chest tube. Choice B, replacing the chest tube, is not necessary as tightening the connections should be attempted first. Clamping the chest tube (Choice C) is not recommended as it can lead to complications by obstructing the drainage system. Continuing to monitor the chest tube (Choice D) without taking action may result in worsening of the air leak. Therefore, the priority intervention is to tighten the connections of the chest tube system.

3. 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.

4. During an escharotomy on a patient with a burn injury, what is the purpose of this procedure?

A. To release pressure and improve circulation in the affected area
B. To remove dead tissue from the burn area
C. To improve breathing by reducing skin tightness
D. To prevent infection in the burned area

Correct answer: A

Rationale: Corrected Question: During an escharotomy on a patient with a burn injury, the purpose of this procedure is to release pressure and improve circulation in the affected area. This intervention is crucial in severe burns where the formation of eschar (dead tissue) can lead to increased pressure, compromising circulation and potentially causing further tissue damage. Choices B, C, and D are incorrect because escharotomy specifically aims to address pressure and circulation issues in severe burn injuries, rather than removing dead tissue, improving breathing, or preventing infection.

5. What is the purpose of an escharotomy in burn management?

A. To relieve pressure and improve circulation in burn injuries
B. To remove necrotic tissue from a wound
C. To prevent infection in burn injuries
D. To remove excess fluid from burn wounds

Correct answer: A

Rationale: An escharotomy is performed to relieve pressure in areas affected by deep burns and improve circulation. This procedure involves making incisions through the eschar (burned and dead tissue) to release constricting tissue and allow for the return of blood flow. Choice B is incorrect because the removal of necrotic tissue is typically done through debridement, not escharotomy. Choice C is incorrect because preventing infection in burn injuries is usually achieved through proper wound care and antibiotic therapy, not escharotomy. Choice D is incorrect because removing excess fluid from burn wounds is managed through methods like fluid resuscitation and monitoring, not escharotomy.
