Correct Answer: B

Rationale: The correct answer is B: Benchmarking. Benchmarking involves comparing performance metrics with those from other units or institutions, which is exactly what the nurse is doing by comparing the rate of medication errors on their medical unit to the rate from a medical unit in a magnet hospital. Choice A, Structure audit, is not relevant to this scenario as it focuses on assessing the physical, organizational, or procedural structures in a healthcare setting. Choice C, Risk benefit analysis, involves weighing the potential risks and benefits of a particular course of action, not comparing performance metrics. Choice D, Root cause analysis, is a method used to identify the underlying causes of problems or adverse events, not to compare performance metrics between units.

Correct Answer: A

Rationale: The correct answer is to check the client's serum glucose level. In a client with diabetes who just had surgery, monitoring the serum glucose level is crucial to ensure proper management of the condition. This helps in preventing complications related to blood sugar fluctuations. Assisting the client out of bed may be important but not the primary responsibility at this time. Placing the client in a high-Fowler's position or ensuring the residual limb is elevated are important interventions for comfort and circulation but are not the primary concern in this scenario.

Correct Answer: D

Rationale: The correct answer is D. An avulsion fracture occurs when a part of the bone is pulled away by a tendon or ligament. Choice A is incorrect because it describes an open fracture where the bone penetrates the skin. Choice B is incorrect as a pathological fracture results from an underlying disease weakening the bone, not physical trauma. Choice C is incorrect as a greenstick fracture involves the bone bending but not completely breaking.

Correct Answer: D

Rationale: Tetralogy of Fallot is characterized by a combination of four heart defects: a sub-aortic septal defect, an overriding aorta, right ventricular hypertrophy, and right ventricular outflow obstruction. This leads to mixing of oxygen-poor and oxygen-rich blood, resulting in cyanosis. Therefore, the correct answer is D. Choices A, B, and C are incorrect because they do not accurately describe the specific combination of anatomic malformations seen in Tetralogy of Fallot.

Correct Answer: D

Rationale: The appropriate response acknowledges the client's concern and confirms that they have the right to change their mind.
