1. What ECG changes are seen in hypokalemia?

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

Correct answer: A

Rationale: The correct answer is A: Flattened T waves on the ECG. Flattened T waves are an early indicator of hypokalemia on an ECG. Choice B, Elevated ST segments, is not typically seen in hypokalemia but can be a sign of myocardial infarction. Choice C, Widened QRS complex, is more commonly associated with hyperkalemia. Choice D, Prominent U waves, is typically associated with hypokalemia, but flattened T waves are considered a more specific and early sign.

2. What should be taught to a patient following cataract surgery?

• A. Avoid NSAIDs
• B. Wear dark glasses when outdoors
• C. Report green or yellow drainage immediately
• D. Itching is normal unless accompanied by pain and nausea

Correct answer: A

Rationale: The correct answer is to avoid NSAIDs after cataract surgery to reduce the risk of bleeding. Choice B, wearing dark glasses when outdoors, is generally recommended after cataract surgery to protect the eyes from bright sunlight, but it is not the most critical instruction. Choice C, reporting green or yellow drainage immediately, is important to monitor for signs of infection, but it is not specific to cataract surgery. Choice D, itching is normal unless accompanied by pain and nausea, is not the most crucial advice post-cataract surgery. Therefore, the key instruction is to avoid NSAIDs to minimize bleeding risk.

3. What is an escharotomy, and why is it performed?

• 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 remove fluid from a burn wound

Correct answer: A

Rationale: An escharotomy is a surgical procedure performed to relieve pressure and improve circulation in areas affected by deep burns. Choice A is the correct answer because the primary goal of an escharotomy is to prevent compartment syndrome caused by increased pressure within the affected tissues. Choices B, C, and D are incorrect because an escharotomy is not primarily performed to reduce pain, remove necrotic tissue, or drain fluid from a burn wound, but to address the specific issue of compromised blood flow and pressure within deep burn injuries.

4. What should a healthcare provider teach a patient who has experienced an acute episode of gastritis?

• A. Avoid foods high in potassium
• B. Avoid foods high in sodium
• C. Increase exercise to reduce stress
• D. Drink milk as a snack

Correct answer: A

Rationale: The correct answer is A: Avoid foods high in potassium. During an acute episode of gastritis, it is advisable to avoid foods high in potassium as they can exacerbate symptoms. Potassium-rich foods may irritate the stomach lining, leading to increased discomfort. Choices B, C, and D are incorrect. Avoiding foods high in sodium is not specifically related to managing gastritis. Increasing exercise to reduce stress is a good general recommendation but not directly related to managing gastritis symptoms. Drinking milk as a snack is not recommended for gastritis as dairy products can sometimes worsen symptoms due to their fat content.

5. A patient has been diagnosed with a thrombotic stroke. What are the expected manifestations?

• A. Gradual loss of function on one side of the body
• B. Sudden loss of consciousness
• C. Seizures and confusion
• D. Loss of sensation in the affected limb

Correct answer: A

Rationale: The correct answer is A: 'Gradual loss of function on one side of the body.' Thrombotic strokes lead to slow and progressive symptoms as a result of decreased blood flow to a specific area of the brain. Choices B, C, and D are incorrect because sudden loss of consciousness, seizures, confusion, and loss of sensation in the affected limb are not typical manifestations of a thrombotic stroke.
