Nursing Elites

1. A client with acute kidney injury (AKI) is experiencing hyperkalemia. What intervention should the nurse prioritize?

• A. Administer IV calcium gluconate.
• B. Administer sodium polystyrene sulfonate (Kayexalate).
• C. Administer insulin with dextrose.
• D. Restrict potassium intake in the client's diet.

Correct answer: A

Rationale: The correct intervention for a client with acute kidney injury (AKI) experiencing hyperkalemia is to administer IV calcium gluconate. Calcium gluconate helps stabilize the myocardium and prevent life-threatening arrhythmias in hyperkalemia by antagonizing the cardiac effects of high potassium levels. Choice B, administering sodium polystyrene sulfonate (Kayexalate), is used to lower potassium levels in the gastrointestinal tract but is not the priority in acute severe hyperkalemia. Choice C, administering insulin with dextrose, helps drive potassium into cells but is not the priority in a client at risk for arrhythmias due to hyperkalemia. Choice D, restricting potassium intake in the client's diet, is a long-term strategy but is not the immediate priority in managing acute hyperkalemia.

2. To prevent unnecessary hypoxia during suctioning of a tracheostomy, what must the nurse do?

• A. Apply suction for no more than 10 seconds
• B. Maintain sterile technique
• C. Lubricate 3 to 4 inches of the catheter tip
• D. Withdraw catheter in a circular motion

Correct answer: A

Rationale: The correct answer is to apply suction for no more than 10 seconds. Prolonged suctioning can lead to hypoxia, so it is essential to limit the suctioning time. Maintaining sterile technique (choice B) is important to prevent infections but is not directly related to preventing hypoxia during suctioning. Lubricating the catheter tip (choice C) helps with insertion but does not specifically address hypoxia prevention. Withdrawing the catheter in a circular motion (choice D) is not a standard practice during tracheostomy suctioning and does not help prevent hypoxia.

3. The nurse is caring for a client with deep vein thrombosis (DVT) who is receiving anticoagulant therapy. Which intervention should the nurse implement to prevent complications?

• A. Elevate the affected leg
• B. Encourage early ambulation
• C. Perform frequent range-of-motion exercises
• D. Apply ice packs to the affected leg

Correct answer: A

Rationale: Elevating the affected leg is crucial in managing deep vein thrombosis (DVT) as it helps to reduce swelling and improve venous return. This intervention is essential for preventing complications such as pulmonary embolism. Encouraging early ambulation is generally beneficial for preventing DVT but is secondary to leg elevation. Performing range-of-motion exercises can be helpful for maintaining joint mobility but is not the priority intervention in this case. Applying ice packs to the affected leg is not recommended in DVT management as it can cause vasoconstriction and potentially worsen the condition.

4. A client with rheumatoid arthritis has just been prescribed methotrexate. What teaching should the nurse include?

• A. Take the medication on an empty stomach.
• B. Report any signs of infection, such as a sore throat.
• C. Take folic acid supplements to prevent anemia.
• D. Use sunscreen to prevent photosensitivity.

Correct answer: D

Rationale: The correct answer is D: 'Use sunscreen to prevent photosensitivity.' Methotrexate increases photosensitivity, so clients should be advised to use sunscreen to protect their skin from sun exposure. Choice A is incorrect because methotrexate is usually taken with food to reduce gastrointestinal side effects. Choice B may be important but is not specific to methotrexate therapy. Choice C is also important, but the primary reason for folic acid supplementation with methotrexate is to reduce the risk of certain side effects like anemia rather than preventing anemia itself.

5. A client with pheochromocytoma is admitted to the hospital. Which intervention has the highest priority?

• A. Monitor blood pressure frequently
• B. Start intravenous fluids at a fast rate
• C. Administer pain medication to reduce discomfort
• D. Give antihypertensive medications as prescribed

Correct answer: B

Rationale: The correct answer is B: Start intravenous fluids at a fast rate. In a client with pheochromocytoma, the highest priority intervention is to ensure adequate intravascular volume before initiating any other treatment. This helps prevent a sudden drop in blood pressure that can occur due to the release of catecholamines during tumor manipulation. While monitoring blood pressure frequently is essential, ensuring adequate intravascular volume takes precedence. Administering pain medication and antihypertensive medications are important but are not the highest priority in the initial management of pheochromocytoma.
