Correct Answer: B

Rationale: Ten seconds is the usual amount of time the nurse should spend for each suction pass. Two seconds is not enough time to effectively remove secretions, while 20 and 30 seconds are too long and could lead to hypoxia and tissue trauma. Therefore, the correct choice is 10 seconds, as it strikes a balance between removing secretions adequately and minimizing the risks associated with prolonged suctioning.

Correct Answer: A

Rationale: When a chest tube becomes disconnected, the priority action is to immediately reattach it to the drainage system or submerge the end in a bottle of sterile water or saline solution to reestablish a water seal. This helps prevent air from entering the pleural space and causing complications. Calling the health care provider is important but not the first action in this emergency. Instructing the client to inhale and hold his breath should be avoided as it can introduce atmospheric air into the pleural space, leading to potential issues. Clamping the chest tube is generally contraindicated, especially in cases of residual air leak or pneumothorax, as it may result in a tension pneumothorax by preventing air from escaping.

Correct Answer: D

Rationale: The five rights of medication administration are dose, client, drug, route, and time. The correct answer is 'routine' as it is not commonly recognized as one of the essential rights in medication administration. Choice A, client, is necessary to ensure the right medication is administered to the right individual. Choice B, drug, is crucial to confirm the correct medication is given. Choice C, dose, is essential to ensure the right amount of medication is administered. Choice D, routine, is not typically included in the five rights of medication administration and is therefore the correct answer.

Correct Answer: B

Rationale: A nursing advocate does not make decisions for others but instead empowers individuals to make decisions for themselves. By encouraging individuals to make their own decisions and supporting them in this process, nursing advocates uphold the principle of self-determination. This approach respects the autonomy and independence of individuals in managing their care. Therefore, the correct answer is to 'encourage persons to make decisions for themselves and act with or on behalf of the person to support those decisions.' Choices A, C, and D are incorrect as they do not align with the role of a nursing advocate in promoting patient autonomy and self-determination.

Correct Answer: D

Rationale: The most appropriate nursing diagnosis for Mrs. Peterson is 'Sleep Pattern Disturbances (related to chronic leg pain).' Mrs. Peterson's sleep issues are directly linked to her chronic leg pain, which is a result of her arthritis. This nursing diagnosis addresses the primary cause of her sleep disturbances and allows for interventions that focus on managing the pain to improve her sleep. Choices A, B, and C are incorrect. Choice A correctly identifies the relationship between sleep disturbances and chronic leg pain, addressing the root cause. Choice B is incorrect as it only focuses on fatigue and does not encompass the broader sleep issues. Choice C is not relevant as there is no indication that Mrs. Peterson lacks knowledge about sleep hygiene measures.
