Nursing Elites

1. 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.

2. 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.

3. What are the expected ECG findings in hypokalemia?

• A. Flattened T waves
• B. Prominent U waves
• C. Elevated ST segments
• D. Wide QRS complex

Correct answer: A

Rationale: Flattened T waves are the classic ECG finding in hypokalemia. Hypokalemia primarily affects the repolarization phase of the cardiac action potential, leading to T wave abnormalities. While prominent U waves are typically associated with hypokalemia as well, flattened T waves are the most specific and sensitive ECG abnormality seen in hypokalemia. Elevated ST segments and wide QRS complexes are not typically seen in hypokalemia and are more indicative of other electrolyte imbalances or cardiac conditions.

4. What ECG changes are expected in hypokalemia?

• A. Flattened T waves on ECG
• B. Prominent U waves on ECG
• C. Widened QRS complexes on ECG
• D. ST elevation on ECG

Correct answer: A

Rationale: In hypokalemia, flattened T waves are a common ECG finding due to the decreased extracellular potassium affecting repolarization. Prominent U waves are typically seen in hypokalemia as well, but flattened T waves are the more specific and early ECG change. Widened QRS complexes are associated with hyperkalemia, not hypokalemia. ST elevation is often seen in conditions like myocardial infarction, pericarditis, or early repolarization syndrome, not specifically in hypokalemia.

5. What dietary teaching should be provided to a patient with GERD?

• A. Avoid mint and pepper
• B. Consume liquids with meals
• C. Increase fluid intake with meals
• D. Eat large meals before bed

Correct answer: A

Rationale: The correct dietary teaching for a patient with GERD is to avoid mint and pepper. Mint and pepper can trigger reflux symptoms and increase gastric acid secretion, exacerbating GERD. Choices B and C are not recommended for patients with GERD as consuming liquids with meals and increasing fluid intake during meals can contribute to reflux by distending the stomach. Choice D, eating large meals before bed, can also worsen GERD symptoms by increasing pressure on the lower esophageal sphincter and promoting reflux.
