Nursing Elites

1. Which lab value is critical for patients on warfarin therapy?

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

Correct answer: A

Rationale: The correct answer is to monitor INR levels for patients on warfarin therapy. INR monitoring is essential because it helps assess the clotting tendency of the blood and ensures that patients are within the therapeutic range to prevent both blood clots and excessive bleeding. Monitoring potassium levels (Choice B), sodium levels (Choice C), or platelet count (Choice D) is not specifically required for patients on warfarin therapy and does not directly impact the effectiveness or safety of the medication.

2. A nurse is providing discharge teaching to a client who has a new diagnosis of diabetes mellitus. Which of the following client statements indicates a need for further teaching?

• A. I will check my blood glucose level once a week.
• B. I will eat a snack if my blood glucose level is above 200 mg/dL.
• C. I will take my insulin as prescribed, even when I am feeling well.
• D. I will avoid physical activity if my blood glucose level is below 100 mg/dL.

Correct answer: B

Rationale: The correct answer is B. Clients should eat a snack when their blood glucose level is low, typically below 70-100 mg/dL, not when it is high. Eating a snack when the blood glucose level is above 200 mg/dL can exacerbate hyperglycemia. Choice A is correct as checking blood glucose levels regularly is important in managing diabetes. Choice C is also correct as adherence to prescribed insulin therapy is crucial. Choice D is incorrect as physical activity can help lower blood glucose levels, especially when they are above the target range.

3. A healthcare professional is preparing to administer digoxin to a client with heart failure. Which of the following laboratory values should the professional report to the provider?

• A. Potassium 4.0 mEq/L
• B. Calcium 9.5 mg/dL
• C. Sodium 140 mEq/L
• D. Magnesium 2.0 mg/dL

Correct answer: C

Rationale: The correct answer is C: Sodium 140 mEq/L. An elevated sodium level can affect the effectiveness of digoxin therapy and may lead to toxicity. Therefore, it is crucial to report this value to the provider. Potassium, calcium, and magnesium levels are important as well, but elevated sodium can have a more direct impact on digoxin therapy in this scenario.

4. A nurse is caring for a client who is in a seclusion room following violent behavior. The client continues to display aggressive behavior. Which of the following actions should the nurse take?

• A. Confront the client about this behavior
• B. Express sympathy for the client's situation
• C. Speak assertively to the client
• D. Stand within 30 cm (1 ft) of the client when speaking with them

Correct answer: C

Rationale: In this situation, speaking assertively is the most appropriate action for the nurse to take. Confronting the client may escalate the situation further. Expressing sympathy, although important in other contexts, may not be effective in managing aggressive behavior. Standing within close proximity to an aggressive client can compromise the nurse's safety. Therefore, speaking assertively helps to set clear boundaries and manage the situation while ensuring safety in a seclusion room.

5. A nurse is assessing a client who has chronic obstructive pulmonary disease (COPD). Which of the following findings should the nurse expect?

• A. Increased oxygen saturation with exercise.
• B. Pursed-lip breathing with exertion.
• C. Productive cough with clear sputum.
• D. Clubbing of the fingers.

Correct answer: C

Rationale: The correct answer is C: 'Productive cough with clear sputum.' Clients with COPD often have a chronic productive cough with thick, often purulent sputum. This sputum can be white, yellow, green, or clear. Choices A, B, and D are incorrect. Oxygen saturation may decrease with exertion in COPD due to impaired gas exchange. Pursed-lip breathing is used to control dyspnea, not directly related to increased saturation with exercise. Clubbing of the fingers is typically seen in conditions such as cyanotic heart disease or lung cancer.
