What is the role of a nurse in managing a patient with acute kidney injury (AKI)?

Correct Answer: A

Rationale: The correct answer is A: 'Monitor urine output and electrolyte levels.' In managing a patient with acute kidney injury (AKI), it is crucial for the nurse to monitor urine output and electrolyte levels to assess kidney function and the patient's fluid and electrolyte balance. This monitoring helps in early detection of any worsening kidney function or electrolyte imbalances. Choice B is incorrect because administering diuretics and restricting potassium may not be appropriate for all AKI patients and should be done under the direction of a healthcare provider. Choice C is also incorrect as providing dietary education and monitoring fluid intake are important but do not directly address the immediate management of AKI. Choice D is incorrect as administering antibiotics and checking for dehydration are not primary interventions for managing AKI; antibiotics are only given if there is an infection contributing to AKI, and dehydration should be managed but is not the primary role of the nurse in AKI management.

Correct Answer: A

Rationale: The correct signs of hyperkalemia include elevated potassium levels and muscle weakness. The treatment involves administering calcium gluconate to help stabilize the heart. Choice B is incorrect as hyperkalemia is characterized by elevated, not decreased, potassium levels. Choice C is incorrect as hyperkalemia does not involve elevated sodium levels, and the treatment is not sodium bicarbonate. Choice D is incorrect as hyperkalemia does not lead to low sodium levels, and sodium chloride is not the treatment for hyperkalemia.

Correct Answer: A

Rationale: The correct answer is A: Administer antibiotics and monitor oxygen levels. Antibiotics are essential to treat the infection caused by bacteria in pneumonia, while monitoring oxygen levels helps ensure adequate oxygenation. Administering bronchodilators and encouraging deep breathing, as in choice B, are more commonly associated with managing conditions like asthma or COPD, not pneumonia. Providing fluids and monitoring for dehydration, as in choice C, are important for various conditions but not specific to pneumonia management. Administering oxygen and providing bed rest, as in choice D, may be supportive measures in pneumonia treatment, but the key intervention is administering antibiotics.

Correct Answer: A

Rationale: The correct intervention for a patient with hypokalemia is to administer potassium supplements and monitor the ECG. Potassium supplements help correct the low potassium levels in the body, while ECG monitoring is essential to detect any cardiac arrhythmias associated with hypokalemia. Choice B is incorrect because a high-sodium diet would worsen hypokalemia by further depleting potassium levels. Choice C is incorrect as it only focuses on monitoring symptoms and providing dietary education, but does not address the immediate need to correct potassium levels. Choice D is also incorrect as administering diuretics would exacerbate hypokalemia by increasing potassium loss.

Correct Answer: A

Rationale: Correct answer: The most appropriate management for a patient with congestive heart failure is to administer diuretics to help remove excess fluid and monitor fluid balance. Diuretics help reduce the workload on the heart and alleviate symptoms of fluid overload. Choice B is incorrect because patients with congestive heart failure are usually advised to limit sodium intake and carefully monitor fluid intake. Choice C is incorrect because although oxygen therapy may be necessary in certain cases, it is not the primary management for congestive heart failure. Pain relief is not a primary intervention for this condition. Choice D is incorrect because bronchodilators are not the first-line treatment for congestive heart failure. Encouraging mobility is important, but administering diuretics and monitoring fluid balance take precedence in managing this condition.
