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 emphysema reports shortness of breath. What is the nurse's priority action?

• A. Administer oxygen therapy.
• B. Assess the client’s respiratory rate and effort.
• C. Prepare the client for intubation.
• D. Increase the client's oxygen flow rate.

Correct answer: B

Rationale: Shortness of breath in a client with emphysema may indicate respiratory distress. Assessing the client’s respiratory rate and effort is the first priority to determine the severity of the distress and guide appropriate interventions. Administering oxygen therapy (Choice A) could be necessary, but assessing the client first is crucial to tailor the intervention. Intubation (Choice C) is an invasive procedure that is not the initial priority. Increasing oxygen flow rate (Choice D) should only be done after a thorough assessment to avoid potential harm.

3. Prolonged exposure to high concentrations of supplemental oxygen over several days can cause which pathophysiological effect?

• A. Reduced cardiac output
• B. Disrupted surfactant production
• C. Hyperactivity of alveoli
• D. Increased oxygen carrying capacity

Correct answer: B

Rationale: Corrected Rationale: Prolonged exposure to high oxygen concentrations can disrupt the production of surfactant in the lungs, leading to atelectasis and other lung complications. Surfactant is essential for maintaining lung compliance and preventing alveolar collapse. Reduced cardiac output (Choice A) is not directly associated with prolonged oxygen exposure. Hyperactivity of alveoli (Choice C) is not a recognized consequence of high oxygen levels. Increased oxygen carrying capacity (Choice D) is not a pathophysiological effect of prolonged high oxygen exposure.

4. Which statement made by the client indicates an understanding of the instructions regarding the administration of alendronate (Fosamax)?

• A. I will take the medication at bedtime to avoid stomach upset.
• B. I will take the medication with a full glass of water first thing in the morning.
• C. I will lie down for 30 minutes after taking the medication.
• D. I will take the medication with food to reduce stomach irritation.

Correct answer: B

Rationale: The correct answer is B. Alendronate (Fosamax) should be taken with a full glass of water in the morning to prevent esophageal irritation and ensure proper absorption. Choice A is incorrect because taking alendronate at bedtime increases the risk of esophageal irritation due to lying down. Choice C is incorrect because patients should remain upright for at least 30 minutes after taking alendronate to prevent esophageal irritation. Choice D is incorrect because alendronate should be taken on an empty stomach, not with food, to enhance absorption.

5. The client with a below-the-knee amputation is being taught about proper care of the residual limb. The most important point to emphasize would be

• A. Wrap the stump with an elastic bandage to prevent swelling
• B. Keep the skin on the stump clean and dry
• C. Use alcohol to cleanse the stump daily
• D. Apply moisturizing lotion to the stump daily

Correct answer: B

Rationale: The correct answer is B: Keep the skin on the stump clean and dry. This is crucial for preventing infection and promoting healing of the residual limb. Wrapping the stump with an elastic bandage can constrict blood flow and cause issues. Using alcohol to cleanse the stump daily can be too harsh and drying for the skin, leading to irritation. Applying moisturizing lotion daily is not as essential as keeping the skin clean and dry to prevent complications.
