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 nurse is planning discharge teaching for a client with congestive heart failure (CHF). Which dietary instruction should the nurse provide?

• A. Limit sodium intake to reduce fluid retention
• B. Consume high-protein foods to strengthen the heart
• C. Increase potassium intake to manage blood pressure
• D. Increase fluid intake to promote hydration

Correct answer: A

Rationale: The correct answer is A: Limit sodium intake to reduce fluid retention. Limiting sodium intake is crucial for managing congestive heart failure (CHF) as it helps reduce fluid retention. Excess fluid retention can worsen CHF by increasing the workload on the heart. Choice B is incorrect because while protein is essential for overall health, it is not directly related to managing CHF. Choice C is incorrect because potassium, although important, is not the primary focus in managing CHF. Choice D is incorrect because increasing fluid intake can exacerbate fluid retention in CHF patients.

3. A client with chronic obstructive pulmonary disease (COPD) is admitted with increasing shortness of breath. What is the nurse's priority action?

• A. Administer oxygen via nasal cannula.
• B. Reposition the client to improve breathing.
• C. Perform chest physiotherapy.
• D. Encourage the client to cough and deep breathe.

Correct answer: A

Rationale: The correct answer is A: Administer oxygen via nasal cannula. Oxygen therapy is the priority intervention for a client with COPD experiencing increasing shortness of breath. It helps improve oxygenation and relieve respiratory distress. Choice B is not the priority as oxygenation needs to be addressed first. Choice C, chest physiotherapy, may be beneficial but is not the immediate priority in this situation. Choice D, encouraging the client to cough and deep breathe, is not the priority intervention when oxygenation is compromised.

4. The nurse is evaluating the laboratory reports of a client with hypothyroidism. The nurse would expect which of the following laboratory values?

• A. Increased TSH
• B. Increased thyroxine (T4)
• C. Decreased TSH
• D. Decreased T3

Correct answer: A

Rationale: The correct answer is A: Increased TSH. In hypothyroidism, the thyroid gland is underactive, leading to low levels of thyroid hormones. As a compensatory mechanism, the pituitary gland releases more thyroid-stimulating hormone (TSH) to try to stimulate the thyroid gland to produce more hormones. Therefore, increased TSH levels are expected in hypothyroidism. Choice B is incorrect because in hypothyroidism, thyroxine (T4) levels are usually decreased, not increased. Choice C is incorrect as hypothyroidism is characterized by increased TSH levels, not decreased. Choice D is also incorrect because in hypothyroidism, T3 levels may be decreased, but TSH is a more sensitive indicator for diagnosis.

5. 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.
