1. 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.

2. 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.

3. What should be monitored for in a patient with compartment syndrome?

• A. Unrelieved pain, pallor, and pulselessness
• B. Localized redness and swelling
• C. Fever and infection
• D. Muscle weakness and fatigue

Correct answer: A

Rationale: Correct Answer: A. Unrelieved pain, pallor, and pulselessness are classic signs of compartment syndrome that indicate inadequate blood flow to the affected area. These symptoms are crucial to monitor as they signify a medical emergency requiring immediate intervention. Choices B, C, and D are incorrect because they do not align with the typical manifestations of compartment syndrome. Localized redness and swelling may be present but are not the primary indicators. Fever and infection are also not specific to compartment syndrome, and muscle weakness and fatigue are not typically prominent symptoms of this condition.

4. What are the signs and symptoms of a hemorrhagic stroke?

• A. Sudden severe headache, decreased level of consciousness, and seizures
• B. Loss of consciousness and weakness
• C. Temporary vision loss
• D. Severe chest pain and shortness of breath

Correct answer: A

Rationale: The correct answer is A. A hemorrhagic stroke often presents with a sudden severe headache, decreased level of consciousness, and seizures due to bleeding in the brain. Choice B, loss of consciousness and weakness, is more indicative of an ischemic stroke where a clot blocks blood flow to the brain. Choice C, temporary vision loss, is more commonly seen in conditions like transient ischemic attacks (TIAs) or retinal migraines. Choice D, severe chest pain and shortness of breath, are symptoms more associated with cardiac issues like a heart attack.

5. A client with Ménière's disease is experiencing episodes of vertigo. Which of the following interventions should the nurse include in the plan of care?

• A. Maintain strict bed rest
• B. Restrict fluid intake to the morning hours
• C. Administer aspirin
• D. Provide a low sodium diet

Correct answer: D

Rationale: The correct intervention for a client with Ménière's disease experiencing vertigo is to provide a low sodium diet. This helps reduce fluid retention, which can alleviate the symptoms of Ménière's disease. Maintaining strict bed rest is not necessary and can lead to deconditioning. Restricting fluid intake to the morning hours does not specifically address the underlying cause of Ménière's disease. Administering aspirin is not indicated for Ménière's disease and can potentially worsen symptoms.
