1. 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.

2. 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.

3. What should the healthcare provider do first when a patient is admitted with chest pain and possible acute coronary syndrome?

• A. Administer sublingual nitroglycerin
• B. Get IV access
• C. Auscultate heart sounds
• D. Obtain cardiac enzymes

Correct answer: A

Rationale: Administering sublingual nitroglycerin is the priority intervention when a patient presents with chest pain and suspected acute coronary syndrome. Nitroglycerin helps dilate blood vessels, improve blood flow to the heart, and relieve chest pain. It is crucial to address the pain and potential ischemia promptly to prevent further cardiac tissue damage. Getting IV access, auscultating heart sounds, and obtaining cardiac enzymes are important assessments and interventions, but administering nitroglycerin takes precedence in managing acute coronary syndrome.

4. A patient with a chest tube has continuous bubbling in the water seal chamber. What does this indicate?

• A. An air leak
• B. A blocked chest tube
• C. Drainage from the site
• D. Blood clot in the chest tube

Correct answer: A

Rationale: Continuous bubbling in the water seal chamber of a chest tube indicates an air leak. This situation requires immediate attention to prevent complications such as lung collapse. A blocked chest tube would typically result in absent or fluctuating bubbling. Drainage from the site would be observed in the collection chamber, not the water seal chamber. A blood clot in the chest tube would lead to cessation of drainage.

5. A client has a Transient Ischemic Attack (TIA). What should the nurse teach?

• A. Avoid eating within 3 hours of bedtime
• B. Consume liquids between meals
• C. Eat large meals to increase caloric intake
• D. Avoid liquids to prevent aspiration

Correct answer: A

Rationale: The correct answer is A: Avoid eating within 3 hours of bedtime. For a client with a Transient Ischemic Attack (TIA), it is crucial to avoid eating within 3 hours of bedtime to reduce reflux that can worsen symptoms. Choice B is incorrect because consuming liquids between meals is not specifically related to managing TIA. Choice C is incorrect as eating large meals may not be recommended, especially if the client needs to watch their caloric intake. Choice D is incorrect because avoiding liquids entirely can lead to dehydration and is not a standard recommendation for TIA management.
