Nursing Elites

1. A client with heart failure is being discharged with a prescription for digoxin (Lanoxin). The nurse should include which instruction in the discharge teaching?

• A. Take your pulse before each dose and hold the medication if your pulse is below 60 beats per minute
• B. Increase your fluid intake to at least 3 liters per day
• C. Report any weight loss of more than 2 pounds in a week
• D. Take the medication with meals to avoid gastrointestinal upset

Correct answer: A

Rationale: The correct instruction for a client taking digoxin is to monitor the pulse before each dose and hold the medication if the pulse is below 60 beats per minute. Digoxin can cause bradycardia, so it is crucial to assess the pulse rate before administration to prevent potential complications. Choices B, C, and D are incorrect because increasing fluid intake, reporting weight loss, or taking the medication with meals are not specific instructions related to the safe use of digoxin.

2. A client is admitted with coronary artery disease (CAD) and reports dyspnea at rest. What is the nurse's priority intervention?

• A. Elevate the head of the bed.
• B. Administer oxygen.
• C. Perform continuous ECG monitoring.
• D. Apply a nasal cannula.

Correct answer: A

Rationale: The nurse's priority intervention for a client with coronary artery disease (CAD) experiencing dyspnea at rest is to elevate the head of the bed. Elevating the head of the bed helps improve lung expansion and reduces the workload on the heart, aiding in respiratory effort and cardiac function. This intervention is crucial in enhancing oxygenation and optimizing cardiac output in individuals with CAD presenting with dyspnea. Administering oxygen (Choice B) is important but elevating the head of the bed takes precedence as it directly addresses the client's respiratory distress. Continuous ECG monitoring (Choice C) and applying a nasal cannula (Choice D) are relevant interventions but not the priority when a client with CAD reports dyspnea at rest.

3. The LPN/LVN is assisting in caring for a client in the telemetry unit who is receiving an intravenous infusion of 1000 mL of 5% dextrose with 40 mEq of potassium chloride. Which occurrence observed on the cardiac monitor indicates the presence of hyperkalemia?

• A. Tall, peaked T waves
• B. ST segment depressions
• C. Shortened P-R intervals
• D. Shortening of the QRS complex

Correct answer: A

Rationale: In hyperkalemia, tall, peaked T waves are a distinct ECG finding. These T waves can be seen as a result of increased serum potassium levels, affecting the repolarization phase of the cardiac action potential. It is crucial for healthcare providers to recognize this ECG change promptly as hyperkalemia can lead to serious cardiac arrhythmias and complications. ST segment depressions, shortened P-R intervals, and shortening of the QRS complex are not typically associated with hyperkalemia. ST segment depressions are more indicative of myocardial ischemia or infarction. Shortened P-R intervals may be seen in conditions like Wolff-Parkinson-White syndrome. Shortening of the QRS complex is associated with conditions affecting the conduction system of the heart, such as bundle branch blocks.

4. The nurse is assisting in the care of a client experiencing an acute myocardial infarction (MI). Which medication would the nurse expect to be administered to help reduce myocardial oxygen demand?

• A. Aspirin
• B. Morphine
• C. Atropine
• D. Lidocaine

Correct answer: B

Rationale: In the context of an acute myocardial infarction (MI), morphine is administered to relieve pain and reduce myocardial oxygen demand. By alleviating pain and anxiety, morphine helps reduce oxygen demand on the heart, which is beneficial in the setting of an MI. Aspirin, commonly used for its antiplatelet effects, helps inhibit platelet aggregation and is crucial in the management of MI to prevent further clot formation. Atropine is a medication used to treat symptomatic bradycardia by increasing heart rate, not commonly indicated in the management of acute MI. Lidocaine is used for ventricular dysrhythmias and is not typically given to reduce myocardial oxygen demand in an acute MI scenario.

5. The healthcare professional is assisting in the care of a client diagnosed with heart failure. The client is receiving furosemide (Lasix). Which laboratory value should the healthcare professional monitor most closely?

• A. Serum calcium
• B. Serum potassium
• C. Serum sodium
• D. Serum glucose

Correct answer: B

Rationale: Furosemide is a loop diuretic that can lead to significant potassium loss, making it crucial to monitor the client's serum potassium levels. Hypokalemia (low potassium levels) can result from furosemide use, potentially leading to adverse effects such as cardiac dysrhythmias. Therefore, close monitoring of serum potassium levels is essential to prevent complications in clients receiving furosemide. Monitoring serum calcium, sodium, or glucose levels is not the priority when administering furosemide.
