Nursing Elites

1. The nurse is caring for a client with an acute myocardial infarction. Which symptom requires immediate intervention?

• A. Dizziness
• B. Shortness of breath
• C. Severe chest pain
• D. Nausea and vomiting

Correct answer: C

Rationale: Severe chest pain is the hallmark symptom of an acute myocardial infarction (heart attack) and requires immediate intervention to prevent further damage to the heart muscle. Chest pain in this context is often described as crushing, pressure, tightness, or heaviness. It can radiate to the arms, neck, jaw, back, or upper abdomen. Other symptoms like dizziness, shortness of breath, nausea, and vomiting may also occur in acute myocardial infarction, but chest pain is the most critical sign requiring prompt action as it signifies inadequate blood flow to the heart muscle. Shortness of breath may indicate heart failure, while nausea and vomiting can be associated with the sympathetic response to myocardial infarction. Dizziness could result from decreased cardiac output but is not as specific to myocardial infarction as severe chest pain.

2. A client with a recent myocardial infarction is prescribed a beta-blocker. What side effect should the nurse monitor for?

• A. Monitor the client for bradycardia.
• B. Check the client’s blood pressure for signs of hypotension.
• C. Monitor the client for signs of hyperglycemia.
• D. Monitor for signs of fluid retention.

Correct answer: B

Rationale: The correct answer is B: 'Check the client’s blood pressure for signs of hypotension.' Beta-blockers can lead to decreased heart rate, but bradycardia is not the primary side effect to monitor. Monitoring for bradycardia is more relevant when administering medications like digoxin. Hyperglycemia is associated with medications like corticosteroids, not beta-blockers. Fluid retention is a side effect seen with medications like corticosteroids or calcium channel blockers, not beta-blockers. Therefore, in a client taking a beta-blocker after a myocardial infarction, monitoring for hypotension is crucial due to the medication's mechanism of action.

3. A client with hypertension is prescribed a beta-blocker. What teaching should the nurse provide about this medication?

• A. Instruct the client to avoid high-potassium foods.
• B. Monitor the client’s heart rate and report any bradycardia.
• C. Advise the client to rise slowly from a sitting or lying position.
• D. Instruct the client to avoid sudden position changes.

Correct answer: C

Rationale: The correct answer is to advise the client to rise slowly from a sitting or lying position. Beta-blockers can cause bradycardia and hypotension, so clients should be advised to rise slowly to prevent dizziness and falls. Monitoring the client's heart rate and blood pressure regularly is essential. Instructing the client to avoid high-potassium foods (Choice A) is not directly related to beta-blockers. While monitoring the client's heart rate (Choice B) is important, advising the client to rise slowly (Choice C) is more directly related to potential side effects of beta-blockers. Instructing the client to avoid sudden position changes (Choice D) is not as specific or essential as advising them to rise slowly to prevent adverse effects.

4. After an older client receives treatment for drug toxicity, the healthcare provider prescribes a 24-hour creatinine clearance test. Before starting the urine collection, the nurse noted that the client's serum creatinine was 0.3 mg/dL. Which action should the nurse implement?

• A. Check the client's urine output hourly
• B. Instruct the client to increase fluid intake
• C. Notify the healthcare provider of the results
• D. Start the 24-hour urine collection

Correct answer: C

Rationale: A serum creatinine level of 0.3 mg/dL is abnormally low, indicating potential issues with the interpretation of the creatinine clearance test. It is crucial for the nurse to notify the healthcare provider of this result before proceeding with the 24-hour urine collection. Checking urine output, instructing the client to increase fluid intake, or starting the urine collection without consulting the healthcare provider could lead to incorrect test results and misinterpretation of the client's renal function.

5. A client with a history of atrial fibrillation is prescribed warfarin. What is the nurse's priority teaching?

• A. Avoid eating foods high in potassium.
• B. Avoid foods high in vitamin K.
• C. Take the medication on an empty stomach.
• D. Take the medication at bedtime for best results.

Correct answer: B

Rationale: The correct answer is B: 'Avoid foods high in vitamin K.' Warfarin is an anticoagulant medication that works by interfering with vitamin K-dependent clotting factors. Therefore, consuming foods high in vitamin K can affect the medication's effectiveness. Choices A, C, and D are incorrect because: A) Warfarin is not affected by foods high in potassium; C) Warfarin should be taken with food to minimize gastrointestinal side effects; D) There is no specific requirement for taking warfarin at bedtime for best results.
