Nursing Elites

1. Which electrolyte imbalance is most concerning in a patient taking digoxin?

• A. Monitor potassium levels
• B. Monitor calcium levels
• C. Monitor sodium levels
• D. Monitor magnesium levels

Correct answer: A

Rationale: The correct answer is to monitor potassium levels. Patients taking digoxin are at risk of developing toxicity due to hypokalemia. Low potassium levels can potentiate the toxic effects of digoxin on the heart, leading to serious arrhythmias. Monitoring calcium levels (Choice B) is not the primary concern in patients taking digoxin. While calcium levels play a role in cardiac function, hypocalcemia is not directly associated with digoxin toxicity. Monitoring sodium levels (Choice C) is important for other conditions but is not the primary concern in a patient taking digoxin. Monitoring magnesium levels (Choice D) is also essential, but hypomagnesemia is not as directly linked to digoxin toxicity as hypokalemia.

2. What is the most appropriate action when a patient experiences chest pain?

• A. Administer aspirin
• B. Administer nitroglycerin
• C. Reposition the patient
• D. Prepare for surgery

Correct answer: A

Rationale: Administering aspirin is the correct initial action when a patient experiences chest pain. Aspirin helps reduce the risk of clot formation and is a standard first-line treatment for chest pain related to possible cardiac issues. Administering nitroglycerin may be appropriate based on the underlying cause of chest pain, but aspirin is typically administered first. Repositioning the patient is not the primary intervention for chest pain, and preparing for surgery is not the immediate action required unless indicated by a healthcare provider after assessment.

3. What is the most concerning electrolyte imbalance for a patient receiving digoxin?

• A. Hyperkalemia
• B. Hypokalemia
• C. Hyponatremia
• D. Hypercalcemia

Correct answer: B

Rationale: The correct answer is Hypokalemia. Hypokalemia is the most concerning electrolyte imbalance for a patient receiving digoxin because it can increase the risk of digoxin toxicity. Low potassium levels can potentiate the effects of digoxin on the heart, leading to serious cardiac arrhythmias. Hyperkalemia (Choice A) is not typically associated with digoxin use. Hyponatremia (Choice C) and Hypercalcemia (Choice D) are not directly related to digoxin therapy and do not pose the same risk of toxicity.

4. What is the most critical lab value to monitor for a patient on heparin therapy?

• A. Monitor aPTT levels
• B. Monitor platelet count
• C. Monitor INR levels
• D. Monitor sodium levels

Correct answer: A

Rationale: The correct answer is to monitor aPTT levels. Activated Partial Thromboplastin Time (aPTT) is crucial for assessing the therapeutic effectiveness of heparin, as it reflects the intrinsic pathway of the coagulation cascade. Monitoring aPTT helps ensure that the patient is within the therapeutic range of heparin, minimizing the risk of bleeding complications. Platelet count (choice B) is important to assess for potential heparin-induced thrombocytopenia but is not the primary lab value to monitor during heparin therapy. INR levels (choice C) are monitored in patients on warfarin therapy, not heparin. Sodium levels (choice D) are not directly related to heparin therapy monitoring.

5. A nurse is planning care for a client who has a new diagnosis of heart failure. Which of the following interventions should the nurse include in the plan of care?

• A. Limit the client's fluid intake to 1,500 mL per day.
• B. Encourage the client to walk every 2 hours.
• C. Monitor the client's weight daily.
• D. Administer oxygen via nasal cannula at 2 L/min.

Correct answer: C

Rationale: The correct intervention the nurse should include in the plan of care for a client with heart failure is to monitor the client's weight daily. Daily weight monitoring is essential to assess fluid balance and detect any signs of worsening heart failure. Limiting fluid intake to 1,500 mL per day (Choice A) may be appropriate in some cases, but it is not the initial priority for this client. Encouraging the client to walk every 2 hours (Choice B) is generally beneficial for mobility but may not be directly related to managing heart failure. Administering oxygen via nasal cannula at 2 L/min (Choice D) is a supportive measure for hypoxia but does not directly address heart failure management.
