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.

Correct Answer: B

Rationale: Correct Answer: B. Signs of increased intracranial pressure, such as changes in consciousness or pupil reactivity, are critical to monitor in children with bacterial meningitis to prevent complications. Monitoring the client's skin for rash and lesions (Choice A) is not the priority in bacterial meningitis. While monitoring blood pressure (Choice C) is important, signs of increased intracranial pressure take precedence. Monitoring for changes in heart rate and rhythm (Choice D) is less specific to the condition and may not indicate worsening neurological status.

Correct Answer: D

Rationale: The UAP can be tasked with reporting complaints, monitoring weight gain, and tracking food and fluid intake, all of which are important in managing a client with Cushing's syndrome. These tasks fall within the UAP's scope of practice. Reporting client complaints helps in early identification of complications, monitoring weight is crucial due to fluid retention in Cushing's syndrome, and tracking food and fluid intake assists in dietary management. Choices A, B, and C are all necessary components of care for a client with Cushing's syndrome, making option D the correct answer.

Correct Answer: A

Rationale: The correct answer is A: Monitor the client's urinary output hourly. Clients with burns covering a large percentage of their total body surface area are at high risk for hypovolemia due to fluid loss. Monitoring urinary output is crucial because it helps assess kidney function and fluid balance, providing essential information about the client's hemodynamic status. Applying cool, moist dressings (choice B) is important but not the priority over assessing fluid balance. Administering pain medication (choice C) is essential for comfort but not the priority over monitoring for potential complications like hypovolemia. Administering IV fluids (choice D) is important to prevent hypovolemia, but monitoring urinary output should be the priority to guide fluid resuscitation.
