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 a ruptured spleen underwent an emergency splenectomy. Twelve hours later, the client’s urine output is 25 ml/hour. What is the most likely cause?

• A. This is a normal finding after surgery.
• B. Oliguria signals tubular necrosis related to hypoperfusion.
• C. Oliguria signals dehydration and fluid loss.
• D. Urine output of 25 ml/hour is an expected finding after splenectomy.

Correct answer: B

Rationale: Oliguria, or decreased urine output, after surgery can indicate tubular necrosis due to hypoperfusion, which may require intervention to restore renal function. Choice A is incorrect as oliguria is not a normal finding after surgery. Choice C is incorrect because dehydration is less likely in this context compared to tubular necrosis. Choice D is incorrect as a urine output of 25 ml/hour is not expected after splenectomy and should raise concern for renal impairment.

3. A client with chronic heart failure is admitted with worsening dyspnea. What is the nurse's priority action?

• A. Administer oxygen at 2 liters per nasal cannula.
• B. Administer a diuretic as prescribed.
• C. Assess the client's lung sounds.
• D. Reposition the client to relieve dyspnea.

Correct answer: A

Rationale: In a client with chronic heart failure experiencing worsening dyspnea, the priority action for the nurse is to administer oxygen at 2 liters per nasal cannula. This helps improve oxygenation and alleviate respiratory distress. Administering a diuretic (Choice B) may be necessary but addressing oxygenation comes first. While assessing lung sounds (Choice C) is important, it is not the immediate priority when the client is in respiratory distress. Repositioning the client (Choice D) may help with comfort but does not address the underlying issue of inadequate oxygenation.

4. A client with chronic obstructive pulmonary disease (COPD) is prescribed home oxygen therapy. What teaching should the nurse provide?

• A. Ensure that the client uses oxygen continuously at night.
• B. Instruct the client to avoid smoking and exposure to smoke.
• C. Teach the client how to clean and replace the oxygen tubing.
• D. Instruct the client to increase their fluid intake.

Correct answer: C

Rationale: The correct teaching for a client with COPD prescribed home oxygen therapy is to educate them on how to clean and replace the oxygen tubing. This is crucial to prevent infections and ensure the effectiveness of the oxygen delivery system. Option A is not necessary as oxygen therapy is usually prescribed as needed, not continuously at night. While smoking cessation and avoiding smoke exposure are important in COPD management, it is not directly related to home oxygen therapy. Increasing fluid intake is beneficial for some conditions but is not specifically related to home oxygen therapy for COPD.

5. Which foods should a healthcare provider recommend for a child with phenylketonuria (PKU) to avoid?

• A. Fresh fruit and vegetables
• B. Foods sweetened with aspartame
• C. Bread with honey
• D. Gluten-rich bread

Correct answer: B

Rationale: The correct answer is B: 'Foods sweetened with aspartame.' Children with PKU must avoid foods containing aspartame because it breaks down into phenylalanine, which can worsen their condition. Choice A, fresh fruit and vegetables, are generally healthy and safe for individuals with PKU. Choice C, bread with honey, is also safe unless the bread contains artificial sweeteners like aspartame. Choice D, gluten-rich bread, is not specifically problematic for individuals with PKU unless it contains aspartame or other substances high in phenylalanine.
