Nursing Elites

1. Which electrolyte imbalance is a common concern for patients on loop diuretics?

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

Correct answer: A

Rationale: The correct answer is A, Hypokalemia. Loop diuretics can lead to potassium loss, resulting in hypokalemia. This imbalance is a common concern because potassium plays a vital role in various physiological functions, including maintaining proper heart function. Choices B, C, and D are incorrect because loop diuretics typically do not cause hyperkalemia, hyponatremia, or hypercalcemia.

2. 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.

3. A client is receiving chemotherapy and is being taught about preventing infection. Which of the following instructions should the nurse include?

• A. Take your temperature daily.
• B. Avoid fresh fruits and vegetables.
• C. Limit your intake of high-protein foods.
• D. Increase your intake of high-fat foods.

Correct answer: B

Rationale: Clients receiving chemotherapy are instructed to avoid fresh fruits and vegetables to lower the risk of infection. Fresh produce may harbor bacteria or other pathogens that could be harmful to individuals with compromised immune systems. Taking the temperature daily may be important but is not directly related to preventing infection. Limiting high-protein foods is not necessary unless there are specific dietary restrictions due to the treatment plan. Increasing the intake of high-fat foods is not recommended during chemotherapy as a high-fat diet may lead to other health issues.

4. A nurse is caring for a client who is receiving warfarin therapy. Which of the following laboratory results indicates the need for an increase in the dose of warfarin?

• A. PT 28 seconds
• B. INR 1.2
• C. aPTT 40 seconds
• D. Fibrinogen 350 mg/dL

Correct answer: B

Rationale: An INR of 1.2 is below the therapeutic range for a client on warfarin, indicating inadequate anticoagulation. Therefore, the client would require an increase in the dose of warfarin to achieve the desired therapeutic effect. Choices A, C, and D are not indicative of the need for a dose increase in warfarin therapy. PT of 28 seconds is within the therapeutic range, aPTT of 40 seconds is also within the normal range, and fibrinogen level of 350 mg/dL does not provide information about the anticoagulant effect of warfarin.

5. A nurse is caring for a client who has a Clostridium difficile infection. Which of the following precautions should the nurse implement?

• A. Place the client in a negative pressure room
• B. Wear an N95 respirator mask when entering the room
• C. Wear a gown and gloves when providing care to the client
• D. Place a face mask on the client

Correct answer: C

Rationale: The correct precaution to implement when caring for a client with Clostridium difficile infection is to wear a gown and gloves when providing care. Clostridium difficile is primarily spread through contact with feces, so wearing personal protective equipment like gowns and gloves is crucial in preventing the spread of the infection. Placing the client in a negative pressure room (Choice A) is not necessary for Clostridium difficile. While wearing an N95 respirator mask (Choice B) is important for airborne precautions, it is not required for Clostridium difficile. Placing a face mask on the client (Choice D) is not a standard precaution for preventing the spread of Clostridium difficile.
