Correct Answer: A

Rationale: When a nurse encounters an impaired colleague, the appropriate action is to report the behavior to a supervisor and follow the institution's policy for addressing impaired practice. This ensures patient safety and upholds professional standards. Choice B is incorrect because confronting the colleague directly may not be appropriate or effective in addressing the issue, and the colleague may need more structured assistance. Choice C is a principle of ethical practice but does not directly address the specific situation of dealing with an impaired colleague. Choice D is incorrect because ignoring the colleague's behavior could potentially compromise patient safety and is not in line with professional responsibility.

Correct Answer: D

Rationale: For clients with Cushing's syndrome, they are at risk of developing hypokalemia due to increased excretion of potassium. Therefore, it is essential to advise them to increase their potassium intake. Choices A, B, and C are incorrect because: A) Increasing sodium intake can worsen fluid retention and hypertension common in Cushing's syndrome. B) Limiting protein intake is not necessary unless there are specific kidney issues that require protein restriction. C) Limiting calcium intake is not typically recommended unless there are underlying conditions such as hypercalcemia.

Correct Answer: A

Rationale: Choice A is the correct answer because it describes an effective method of communication where a unit manager meets with a new nurse to discuss what is going well and areas for improvement. This approach fosters open dialogue, provides constructive feedback, and promotes professional growth. Choice B is incorrect as it only involves the explanation of departmental policies without engaging in a two-way communication process. Choice C is incorrect as it focuses on policy introduction after safety events rather than individual feedback. Choice D is incorrect as it involves discussing safety events with another manager and policy improvement, but it does not directly address individual performance feedback, which is essential for effective communication and professional development.

Correct Answer: B

Rationale: In primary adrenal insufficiency (Addison's disease), there is a decrease in aldosterone levels, leading to sodium loss and potassium retention. This imbalance results in hyperkalemia, making choice B the correct answer. Hypernatremia (choice A) is unlikely due to sodium loss. Hyperglycemia (choice C) and hypercalcemia (choice D) are not typically associated with primary adrenal insufficiency.

Correct Answer: A

Rationale: Clients with Cushing's syndrome are at risk for hyperglycemia due to the effects of cortisol on glucose metabolism. Monitoring blood glucose levels is crucial to detect and manage hyperglycemia promptly. Restricting fluid intake (choice B) is not necessary unless specifically indicated for another condition, as clients with Cushing's syndrome are prone to fluid imbalances. Administering potassium supplements (choice C) is not appropriate as clients with Cushing's syndrome often have elevated potassium levels due to the effects of cortisol. Encouraging a high-protein diet (choice D) is not recommended as clients with Cushing's syndrome should focus on a balanced diet to manage their condition effectively.
