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. A client with atrial fibrillation is prescribed warfarin. Which instruction should the nurse include in the teaching?

• A. Maintain a consistent intake of leafy green vegetables
• B. Use an electric razor when shaving
• C. Monitor blood pressure daily
• D. Avoid eating bananas and oranges

Correct answer: B

Rationale: Clients on warfarin are at increased risk of bleeding due to its anticoagulant effects. Using an electric razor reduces the risk of cuts and bleeding, which is an important safety precaution. While leafy greens should not be avoided, their intake should be consistent to maintain a stable level of vitamin K in the body. Monitoring blood pressure daily is important for other conditions but not directly related to warfarin therapy. Avoiding bananas and oranges is not a standard instruction for clients on warfarin.

3. A client with peripheral artery disease reports pain while walking. What intervention should the nurse recommend?

• A. Encourage the client to increase physical activity.
• B. Instruct the client to take rest breaks during walking.
• C. Apply warm compresses to the legs to improve circulation.
• D. Massage the affected leg to relieve the pain.

Correct answer: B

Rationale: Clients with peripheral artery disease often experience claudication (leg pain during walking) due to decreased blood flow. Encouraging rest breaks during walking helps to manage pain and improve circulation. Rest breaks allow the muscles to recover from ischemia caused by inadequate blood supply. Increasing physical activity without breaks may worsen the symptoms. Applying warm compresses can potentially lead to burns or skin damage in individuals with compromised circulation. Massaging the affected leg is contraindicated in peripheral artery disease as it can further compromise blood flow.

4. An unresponsive male victim of a diving accident is brought to the emergency department where immediate surgery is required to save his life. No family members are available. What action should the nurse take first?

• A. Ask the friend to sign an informed consent.
• B. Notify the unit manager that a court order is needed.
• C. Continue providing life support until a guardian is found.
• D. Proceed with surgery preparation without consent.

Correct answer: D

Rationale: In emergency situations where immediate surgery is required to save a patient's life and no family members are available, consent can be waived to proceed with necessary interventions. The priority in this scenario is to proceed with surgery preparation without waiting for consent, as any delay could jeopardize the patient's life. Asking the friend to sign informed consent or notifying the unit manager for a court order would cause unnecessary delays, which are not advisable in this critical situation. Continuing life support until a guardian is found is not the most appropriate action when immediate surgical intervention is necessary.

5. The nurse is reviewing the laboratory results of a client with chronic kidney disease. The client's serum calcium level is 7.5 mg/dL. Which condition should the nurse suspect?

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

Correct answer: D

Rationale: A serum calcium level of 7.5 mg/dL is indicative of hypocalcemia, a common complication in clients with chronic kidney disease due to impaired calcium absorption and metabolism. Hypercalcemia (Choice A) is the opposite of the condition presented in the question and is characterized by elevated serum calcium levels. Hyperkalemia (Choice B) is an increased potassium level, not related to the client's serum calcium level. Hyponatremia (Choice C) is a decreased sodium level and is also not related to the client's serum calcium level.
