1. Which lab value is critical for monitoring warfarin therapy?

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

Correct answer: A

Rationale: The correct answer is A: Monitor INR. INR (International Normalized Ratio) is crucial for monitoring warfarin therapy as it helps assess the therapeutic effectiveness and bleeding risks associated with the medication. INR measures the clotting tendency of blood, which is essential in determining the appropriate dosage of warfarin. Monitoring platelet count (B), sodium levels (C), or calcium levels (D) is not primarily used for assessing warfarin therapy. Platelet count is more relevant in assessing bleeding disorders, while sodium and calcium levels are typically monitored for different medical conditions unrelated to warfarin therapy.

2. A healthcare professional is reviewing the laboratory results of a client who is receiving chemotherapy. Which of the following findings should the healthcare professional report immediately?

• A. White blood cell count of 4,500/mm³
• B. Hemoglobin level of 8 g/dL
• C. Platelet count of 90,000/mm³
• D. Serum potassium level of 3.5 mEq/L

Correct answer: C

Rationale: A platelet count of 90,000/mm³ indicates thrombocytopenia, which increases the risk of bleeding and requires immediate intervention. Thrombocytopenia can lead to serious bleeding complications, so it is crucial to address this finding promptly. A low white blood cell count (choice A) may indicate neutropenia but is not as immediately life-threatening as severe thrombocytopenia. A hemoglobin level of 8 g/dL (choice B) would require intervention but is not as urgent as addressing a critically low platelet count. A serum potassium level of 3.5 mEq/L (choice D) is on the lower side of normal but does not pose an immediate risk to the client's safety compared to severe thrombocytopenia.

3. 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.

4. A client with a history of heart failure is receiving furosemide. Which of the following laboratory values should the nurse monitor?

• A. Sodium 140 mEq/L
• B. Calcium 9.0 mg/dL
• C. Potassium 3.2 mEq/L
• D. Chloride 100 mEq/L

Correct answer: C

Rationale: The correct answer is C: Potassium 3.2 mEq/L. A potassium level of 3.2 mEq/L is below the normal range and should be monitored in clients receiving furosemide due to the risk of hypokalemia. Furosemide is a loop diuretic that can cause potassium depletion, leading to hypokalemia. Monitoring potassium levels is crucial to prevent complications such as cardiac arrhythmias. Choices A, B, and D are not directly impacted by furosemide therapy in the same way as potassium levels, making them less relevant for monitoring in this scenario.

5. A nurse is caring for a client who has bipolar disorder and is experiencing acute mania. The nurse obtained a verbal prescription for restraints. Which of the following actions should the nurse take?

• A. Request a renewal of the prescription every 8 hours.
• B. Check the client's peripheral pulse rate every 30 minutes.
• C. Obtain a prescription for restraint within 4 hours.
• D. Document the client's condition every 15 minutes.

Correct answer: C

Rationale: Obtaining a prescription for restraint within 4 hours is the correct action when managing restraints in a client with acute mania. This timeframe ensures that the use of restraints is promptly evaluated and authorized by a healthcare provider. Requesting a renewal of the prescription every 8 hours (Choice A) is not necessary and may delay appropriate care. Checking the client's peripheral pulse rate every 30 minutes (Choice B) is important but not the immediate priority when dealing with obtaining a prescription for restraints. Documenting the client's condition every 15 minutes (Choice D) is essential for monitoring, but the priority is to secure a prescription for restraints promptly.
