Correct Answer: A

Rationale: Administering pain medication before changing the dressing is the priority action as it will help alleviate the client's pain and improve comfort. Choice B, changing the dressing less frequently, may hinder proper wound care and healing. Applying a topical anesthetic (choice C) might offer some relief but systemic pain medication is more effective. Using a non-adherent dressing (choice D) can reduce pain during dressing changes, but addressing immediate pain with medication is the most appropriate intervention in this case.

Correct Answer: B

Rationale: Practicing pursed-lip breathing is an essential technique to help manage COPD as it can improve oxygenation by promoting better gas exchange. This technique helps to keep the airways open longer during exhalation, preventing air trapping and improving breathing efficiency. Increasing fluid intake can help thin secretions, which is beneficial, but it is not the primary instruction for managing COPD. Avoiding physical activity is not recommended as it can lead to deconditioning and worsen dyspnea in COPD patients. Using a peak flow meter is more commonly associated with monitoring asthma rather than COPD, so it is not the most relevant instruction for managing COPD.

Correct Answer: B

Rationale: During the preoperative assessment, it is crucial for the LPN to inquire about the client's intake of vitamin and mineral supplements. This is important because certain supplements can have effects on coagulation, wound healing, and overall surgical outcomes. Asking about daily calorie consumption (Choice A) is not as pertinent as inquiring about vitamin and mineral supplements in this context. Questioning the client about feeling overweight (Choice C) may not directly impact the surgical outcome compared to the effects of supplements. Inquiring about the post-surgery diet (Choice D) is relevant but not as critical as understanding the client's supplement intake.

Correct Answer: B

Rationale: Postural drainage is a technique used to help remove secretions from specific lung segments. For left lower atelectasis, placing the client in the right lateral Trendelenburg position is most effective. This position helps target the affected area, using gravity to assist in drainage. Placing the client in a supine or low Fowler's position (Choice A) may not effectively target the affected area. Side lying with the right side of the chest elevated (Choice C) would not utilize gravity for optimal drainage. Placing the client prone with pillows under the extremities (Choice D) is not ideal for postural drainage of the left lower lobe.

Correct Answer: C

Rationale: The correct answer is 'C: Justice.' Justice in healthcare ethics involves fairness and providing equal treatment to all individuals in similar situations. In this scenario, ensuring that all clients waiting for a kidney transplant meet the same qualifications aligns with the principle of justice by offering equal opportunities for transplantation. Choice A, 'Fidelity,' pertains to keeping promises and being loyal to patients, not the equal treatment of individuals. Choice B, 'Autonomy,' refers to respecting patients' rights to make decisions about their own care, which is not directly related to the equal qualifications for kidney transplants. Choice D, 'Nonmaleficence,' focuses on the obligation to do no harm, which is important in healthcare but not the primary ethical principle demonstrated in this scenario.
