Correct Answer: A

Rationale: The correct answer is A because the client understanding that they can change their living will whenever they want shows comprehension of advance directives. Choices B, C, and D are incorrect: B is inaccurate as both documents serve different purposes; C may not always be the case based on the client's wishes and legal documents; D is incorrect because a living will is not only for serious illness but also for end-of-life care decisions.

Correct Answer: C

Rationale: The correct answer is C: 'Avoid open flames or smoking near oxygen.' This information is crucial to prevent fire hazards as oxygen supports combustion. Choices A, B, and D are incorrect. Increasing the oxygen flow rate without healthcare provider's instructions can be dangerous. Oxygen should not be turned off when not in use as prescribed by the healthcare provider, and storing oxygen tubing near heat sources poses a risk of fire.

Correct Answer: B

Rationale: The correct answer is to discontinue the infusion (Choice B) as the signs described suggest phlebitis, an inflammation of the vein. Increasing the IV flow rate (Choice A) can exacerbate the condition by increasing the irritation. Elevating the limb (Choice C) and applying a cold compress (Choice D) are not the appropriate interventions for phlebitis. Elevation and cold therapy are more suitable for conditions like swelling or inflammation, but in this case, discontinuing the infusion is the priority to prevent further complications.

Correct Answer: C

Rationale: The correct answer is the use of a special mattress. Special mattresses are designed to reduce pressure on bony prominences, thereby helping to prevent pressure injuries. Frequent repositioning (Choice A) is actually a preventive measure for pressure injuries. Poor nutrition (Choice B) can contribute to delayed wound healing but is not a direct risk factor for pressure injuries. Urinary incontinence (Choice D) can increase the risk of skin breakdown but is not a direct risk factor for pressure injuries.

Correct Answer: B

Rationale: The correct answer is B: Client's response to pain medication. When transferring a client to another unit, it is crucial to communicate how the client is responding to pain medication to ensure continuity of care and appropriate pain management. While nutritional status, daily vital signs, and most recent lab results are important aspects of the client's care, the client's response to pain medication directly impacts their comfort and well-being during the transfer process.
