Correct Answer: B

Rationale: The correct answer is to draw up the cloudy insulin as ordered. NPH insulin is inherently cloudy due to its suspension of insulin crystals. Shaking the vial vigorously can lead to denaturation of the insulin molecules, altering its efficacy. Warming NPH insulin is not necessary as it can cause breakdown of insulin molecules. The nurse should gently roll the vial between hands to mix it before drawing it up to ensure an even distribution of insulin in the suspension.

Correct Answer: A

Rationale: The correct answer is A. An external insulin pump delivers small continuous doses of regular insulin subcutaneously throughout the day to meet the basal insulin needs. The client can also self-administer a bolus dose with an additional dosage from the pump before each meal to cover the mealtime insulin needs. Option B is incorrect as insulin pumps do not typically release programmed doses of insulin into the bloodstream at specific intervals; instead, they infuse insulin subcutaneously. Option C is incorrect as insulin pumps are not surgically attached to the pancreas; they are worn externally. Option D is incorrect as NPH insulin is not commonly used in insulin pumps, and the pumps do not continuously infuse insulin directly into the bloodstream but rather subcutaneously.

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: Postoperative hypotension is a common complication after adrenal tumor removal in a client with Cushing's syndrome. This occurs due to the sudden withdrawal of cortisol, which leads to a relative adrenal insufficiency state. Hyperglycemia (Choice A) is more common preoperatively due to excessive cortisol levels. Hypokalemia (Choice C) and Hyponatremia (Choice D) are also associated with Cushing's syndrome but are less likely to be immediate postoperative complications compared to hypotension.

Correct Answer: C

Rationale: The correct answer is C: Increased energy levels. When a client with hypothyroidism is receiving levothyroxine, increased energy levels indicate that thyroid hormone levels are being normalized, which is a positive response to treatment. This improvement reflects the effectiveness of the medication in addressing the underlying hypothyroidism. Choices A, B, and D are incorrect. Decreased heart rate and decreased appetite may be symptoms of hypothyroidism and would not necessarily indicate the effectiveness of levothyroxine. Increased weight could also be a symptom of hypothyroidism and does not directly reflect the medication's effectiveness.
