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

• A. A surgical incision to release pressure in burn injuries
• B. A procedure to remove dead tissue from wounds
• C. An incision to improve circulation in tight skin after burns
• D. A procedure to remove excess fluid from the chest

Correct answer: A

Rationale: An escharotomy is a surgical incision made to release pressure in a part of the body that has a deep burn and excessive swelling. This procedure is crucial in preventing further damage due to restricted blood flow and compromised circulation. Choice B is incorrect because it describes debridement, which is the removal of dead tissue from wounds. Choice C is incorrect as it does not specifically address the purpose of relieving pressure in burn injuries. Choice D is incorrect as it describes a procedure more related to thoracentesis, which is the removal of excess fluid from the chest, typically the pleural space.

2. What is the first medication to administer for a patient experiencing wheezing due to an allergic reaction?

• A. Albuterol 3 ml via nebulizer
• B. Cromolyn 20 mg via nebulizer
• C. Methylprednisolone 100 mg IV
• D. Aminophylline 500 mg IV

Correct answer: A

Rationale: The correct answer is A, Albuterol 3 ml via nebulizer. Albuterol is the first-line medication for wheezing due to its rapid bronchodilatory effects. Choice B, Cromolyn, is used more for preventing allergic reactions rather than acute relief of wheezing. Choice C, Methylprednisolone, is a steroid used for its anti-inflammatory effects and is not the initial choice for acute relief of wheezing. Choice D, Aminophylline, is a bronchodilator but is not the first-line treatment for wheezing due to allergic reactions.

3. What is the initial nursing action for a patient with chest pain and acute coronary syndrome?

• A. Administer sublingual nitroglycerin
• B. Check the patient's urine output
• C. Check cardiac enzymes
• D. Obtain IV access

Correct answer: A

Rationale: Administering sublingual nitroglycerin is the priority initial action for a patient with chest pain and acute coronary syndrome. Nitroglycerin helps vasodilate coronary arteries, improving blood flow to the heart muscle and reducing chest pain. Checking the patient's urine output (choice B) and cardiac enzymes (choice C) are important assessments but are not the first priority when managing acute chest pain. Obtaining IV access (choice D) is essential for administering medications and fluids, but administering sublingual nitroglycerin takes precedence in the initial management of chest pain in acute coronary syndrome.

4. What ECG changes are seen with hyperkalemia?

• 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 ECG sign of hyperkalemia. Hyperkalemia affects the repolarization phase of the cardiac action potential, leading to changes such as peaked T waves, prolonged PR interval, widened QRS complex, and ultimately sine wave pattern. Elevated ST segments, prominent U waves, and widened QRS complex are not typically associated with hyperkalemia, making choices B, C, and D incorrect.

5. What precaution should be advised to a patient following a cataract surgery?

• A. Wear dark glasses while outdoors
• B. Avoid NSAIDs
• C. Use warm compresses
• D. Apply cold packs

Correct answer: A

Rationale: Following cataract surgery, patients are advised to wear dark glasses while outdoors. This is crucial to protect the eyes from bright light and prevent complications such as excessive glare or discomfort. Choice B, avoiding NSAIDs, is not directly related to post-cataract surgery care. Choices C and D, using warm compresses and applying cold packs, are not typically part of the standard post-operative care for cataract surgery.
