1. What are the expected findings in a patient with hypokalemia?

• A. Cardiac dysrhythmias
• B. Seizures and confusion
• C. Bradycardia
• D. Muscle weakness

Correct answer: A

Rationale: The correct answer is A: Cardiac dysrhythmias. Hypokalemia is commonly associated with cardiac dysrhythmias due to the role potassium plays in maintaining proper electrical conduction in the heart. Choices B, C, and D are incorrect. While hypokalemia can lead to muscle weakness, the most critical and life-threatening manifestation is cardiac dysrhythmias. Seizures and confusion are more commonly associated with other electrolyte imbalances, such as hyponatremia. Bradycardia is not a typical finding in hypokalemia, as it tends to cause tachycardia or other arrhythmias.

2. What are the dietary recommendations for a patient with pre-dialysis end-stage kidney disease?

• A. Reduce phosphorus intake to 700 mg/day
• B. Limit sodium intake to 1,500 mg/day
• C. Restrict protein intake to 0.55-0.60 g/kg/day
• D. Increase protein intake

Correct answer: A

Rationale: The correct recommendation for a patient with pre-dialysis end-stage kidney disease is to reduce phosphorus intake to 700 mg/day. High phosphorus levels can be harmful to individuals with kidney disease as the kidneys may not be able to filter it effectively. While limiting sodium intake to 1,500 mg/day and restricting protein intake to 0.55-0.60 g/kg/day are important in managing kidney disease, the primary concern for this patient population is to control phosphorus levels. Increasing protein intake is not recommended as it can put additional strain on the kidneys. Therefore, option A is the most appropriate recommendation in this scenario.

3. 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.

4. 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.

5. A patient who experienced an acute episode of gastritis should avoid which type of foods?

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

Correct answer: A

Rationale: Patients who have experienced an acute episode of gastritis should avoid foods high in potassium. Potassium-rich foods can irritate the gastric lining, exacerbating gastritis symptoms. Therefore, choices B, C, and D are incorrect. Avoiding foods high in sodium is beneficial for other health conditions like hypertension, increasing exercise is generally good for overall health but not specifically for gastritis management, and drinking milk may provide temporary relief for some but is not a definitive recommendation for gastritis management.
