Nursing Elites

1. A client is admitted with deep vein thrombosis (DVT) and is receiving heparin therapy. What is the most important laboratory value to monitor during heparin therapy?

• A. Prothrombin time (PT)
• B. International normalized ratio (INR)
• C. Activated partial thromboplastin time (aPTT)
• D. Platelet count

Correct answer: C

Rationale: The activated partial thromboplastin time (aPTT) is the most important laboratory value to monitor during heparin therapy. It measures the intrinsic pathway of coagulation and is used to assess the effectiveness of heparin as an anticoagulant. Keeping the aPTT within the therapeutic range is crucial to prevent complications such as bleeding or clot formation. Prothrombin time (PT) and International normalized ratio (INR) are used to monitor warfarin therapy, not heparin. Platelet count is important to assess for thrombocytopenia, a potential side effect of heparin, but it is not the primary laboratory value to monitor the effectiveness of heparin therapy.

2. A client who is bedridden after a stroke is at risk for developing pressure ulcers. Which nursing intervention is most important in preventing this complication?

• A. Apply lotion to the skin every 4 hours.
• B. Reposition the client every 2 hours.
• C. Elevate the head of the bed 30 degrees.
• D. Massage the skin at least twice a day.

Correct answer: B

Rationale: Repositioning the client every 2 hours is crucial in preventing pressure ulcers in bedridden clients. This intervention helps in relieving pressure on specific areas of the body, promoting circulation, and reducing the risk of tissue damage. Applying lotion every 4 hours (Choice A) may not address the root cause of pressure ulcers. Elevating the head of the bed (Choice C) is beneficial for some conditions but not specifically targeted at preventing pressure ulcers. Massaging the skin at least twice a day (Choice D) can actually increase the risk of skin breakdown in individuals at risk for pressure ulcers by causing friction and shearing forces on the skin.

3. A client with chronic obstructive pulmonary disease (COPD) is experiencing increased shortness of breath and fatigue. What is the nurse's first action?

• A. Administer a bronchodilator as prescribed.
• B. Check the client's oxygen saturation.
• C. Reposition the client to a high Fowler's position.
• D. Administer oxygen via nasal cannula.

Correct answer: B

Rationale: The correct first action for a client with COPD experiencing increased shortness of breath and fatigue is to check the client's oxygen saturation. This assessment helps the nurse evaluate the client's respiratory status promptly. Administering a bronchodilator (Choice A) may be necessary but should come after assessing the oxygen saturation. Repositioning the client to a high Fowler's position (Choice C) can help improve breathing but should not precede oxygen saturation assessment. Administering oxygen via nasal cannula (Choice D) may be needed based on the oxygen saturation results, but assessing it first is crucial.

4. A client with hyperkalemia is receiving insulin and glucose. Which laboratory value should the nurse monitor closely?

• A. Monitor the client's blood glucose level.
• B. Monitor the client's sodium level.
• C. Monitor the client's calcium level.
• D. Monitor the client's potassium level.

Correct answer: D

Rationale: The correct answer is to monitor the client's potassium level. When administering insulin and glucose in hyperkalemia, the aim is to shift potassium from the bloodstream into the cells, lowering elevated levels. Therefore, monitoring potassium levels closely is essential to prevent hypokalemia or further complications. Monitoring blood glucose levels (Choice A) is important but not the priority in this scenario. Monitoring sodium (Choice B) and calcium levels (Choice C) is not directly related to the treatment of hyperkalemia with insulin and glucose.

5. The nurse is caring for a client with fluid overload. The most reliable indicator of fluid volume status is

• A. Body weight
• B. Intake and output
• C. Daily weight
• D. Skin turgor

Correct answer: C

Rationale: Daily weight is the most reliable indicator of fluid volume status as it reflects changes in body fluid balance accurately. Body weight alone can fluctuate due to various factors, including food intake and bowel movements, which may not accurately represent fluid status. Intake and output provide information on fluid balance over time but may not reflect immediate changes. Skin turgor is a physical assessment finding that indicates hydration status, not overall fluid volume status.
