Correct Answer: B

Rationale: The correct answer is B: 'Peer pressure can lead to risky behaviors.' Adolescents are at an increased risk for injury due to peer pressure and the tendency to engage in high-risk behaviors. Emphasizing the impact of peer pressure on decision-making can help adolescents make safer choices. Choices A, C, and D are incorrect because adolescents actually have an increased risk of injury, increased responsibility does not always reduce risks, and many adolescents are at risk of engaging in substance abuse.

Correct Answer: C

Rationale: The correct answer is to reposition the client every 4 hours. Repositioning the client helps prevent pressure injuries caused by urinary incontinence by relieving pressure on vulnerable areas of the skin. Choice A, using a heating pad for comfort, is not directly related to preventing pressure injuries. Choice B, applying a barrier cream to the skin, may help protect the skin but does not address the underlying cause of pressure injuries. Choice D, changing the client's position every 2 hours, is more frequent than necessary and may not be as effective in preventing pressure injuries as repositioning every 4 hours.

Correct Answer: B

Rationale: When a client expresses anxiety, it is essential for the nurse to encourage the client to verbalize their feelings. This helps the client express concerns, fears, and uncertainties, enabling the nurse to provide appropriate emotional support. Administering a sedative (Choice A) should not be the initial response as it does not address the underlying emotional needs of the client. Calling the surgeon to address anxiety (Choice C) may not be within the nurse's scope of practice and may not directly address the client's emotional needs. Providing information on post-op care (Choice D) is important but not the priority when the client is experiencing anxiety preoperatively.

Correct Answer: B

Rationale: When a client reports pain and redness at the site of a peripheral IV, indicating signs of phlebitis, the nurse's initial action should be to discontinue the IV line. This helps prevent further complications and ensures patient safety. Applying a cold compress (Choice A) may provide temporary relief but does not address the underlying issue. Notifying the provider (Choice C) is important but not the initial step. Increasing the IV flow rate (Choice D) can exacerbate the inflammation and should be avoided.

Correct Answer: A

Rationale: Corrected Rationale: The nurse should instruct the client to use pursed-lip breathing during activities to help improve oxygenation. Pursed-lip breathing can keep the airways open longer, facilitating better oxygen exchange and making it easier to exhale carbon dioxide. Choice B is incorrect as physical activity, within the client's limitations, is beneficial for maintaining overall health. Choice C is incorrect as weight-bearing exercises are important for bone health but not directly related to improving oxygenation in COPD. Choice D is incorrect as using a humidifier while sleeping can help with moisture in the airways but does not directly impact oxygenation in COPD.
