1. Which ECG change is associated with hyperkalemia?

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

Correct answer: A

Rationale: Flattened T waves are a characteristic ECG change seen in hyperkalemia. Hyperkalemia affects the repolarization phase of the cardiac cycle, leading to T wave abnormalities. Prominent U waves are typically seen in hypokalemia. Elevated ST segments are more indicative of myocardial infarction or pericarditis. Widened QRS complexes are commonly associated with conditions like bundle branch blocks or certain toxicities.

2. What is the first action a healthcare provider should take for a patient with possible acute coronary syndrome?

• A. Administer sublingual nitroglycerin
• B. Get IV access
• C. Auscultate heart sounds
• D. Obtain cardiac enzymes

Correct answer: A

Rationale: Administering sublingual nitroglycerin is the initial priority action for a patient with possible acute coronary syndrome. Nitroglycerin helps dilate blood vessels, reduce chest pain, and improve blood flow to the heart muscle. This helps in relieving symptoms and preventing further damage to the heart. Establishing IV access, auscultating heart sounds, and obtaining cardiac enzymes are important steps in the assessment and management of acute coronary syndrome but are not the first actions to be taken. IV access may be needed for administering medications or fluids, auscultating heart sounds helps in assessing the heart's function, and obtaining cardiac enzymes aids in diagnosing a heart attack.

3. What ECG changes are associated with hyperkalemia?

• A. Flattened T waves
• B. ST depression
• C. Prominent U waves
• D. Elevated ST segments

Correct answer: B

Rationale: Hyperkalemia is known to cause ST depression on an ECG. Flattened T waves are more commonly seen in hypokalemia. Prominent U waves are associated with hypokalemia rather than hyperkalemia. Elevated ST segments are not typical findings in hyperkalemia.

4. 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.

5. A nurse misreads a glucose reading and administers insulin for a blood glucose of 210 instead of 120. What should the nurse monitor the patient for?

• A. Monitor for hyperglycemia
• B. Monitor for signs of hypoglycemia
• C. Administer glucose IV
• D. Document the incident

Correct answer: B

Rationale: The correct answer is B: Monitor for signs of hypoglycemia. The nurse should monitor the patient for hypoglycemia due to the administration of excess insulin. Administering insulin for a blood glucose level of 210 instead of 120 can lead to a rapid drop in blood sugar levels, causing hypoglycemia. Option A is incorrect as hyperglycemia is high blood sugar, which is unlikely in this scenario. Option C is incorrect as administering glucose IV would worsen the hypoglycemia. Option D is not the immediate priority; patient safety and monitoring for adverse effects take precedence.
