Correct Answer: A

Rationale: Adolescents are particularly influenced by peers, so associating with non-smokers may help the student quit smoking. By being surrounded by non-smokers, the student is less likely to feel pressured to smoke and may be encouraged to adopt healthier behaviors. This intervention leverages the power of social influence to support smoking cessation efforts and create a more conducive environment for the student to quit smoking. Choices B, C, and D do not address the social aspect of smoking behavior and the influence of peers on smoking habits, making them less effective interventions in this case.

Correct Answer: D

Rationale: The client's statement that 'This is a new pill I have never taken before' indicates the need for further assessment by the nurse to ensure the medication is correct and safe. Choices A, B, and C do not raise immediate concerns about the medication order; therefore, they are incorrect. Choice A simply provides information about the client's usual medication schedule, choice B is related to the cost of the pills, and choice C expresses fatigue from taking pills, but none of these statements suggest a potential issue with the new medication.

Correct Answer: B

Rationale: Administering 100% oxygen before and after suctioning is crucial to prevent hypoxia, which can occur during tracheal suctioning. Hypoxia can lead to serious complications, making the provision of oxygen essential in maintaining adequate oxygenation levels for the patient undergoing tracheal suctioning. Choice A is incorrect because using a water-soluble lubricant is not directly related to the essential nursing action during tracheal suctioning. Choice C is incorrect as ensuring that the suction catheter is open during insertion is a basic requirement and not the essential action for oxygenation. Choice D is incorrect because assisting the client to assume a semi-Fowler's position is beneficial for comfort and airway alignment but is not as crucial as administering oxygen to prevent hypoxia.

Correct Answer: B

Rationale: The nurse should prioritize addressing the client's emotional needs by engaging in a conversation to understand the underlying feelings behind her statement. By exploring the client's thoughts about death, the nurse can provide appropriate support and interventions tailored to the client's concerns. Rushing to administer pain medication may not address the emotional distress expressed by the client. Initiating antidepressant therapy is not suitable without assessing the client's feelings further. Referring the client to the ethics committee is premature and does not address the immediate emotional needs of the client. Therefore, empathetic communication and assessment of the client's feelings regarding her situation are crucial for providing holistic care.

Correct Answer: B

Rationale: An irregular heart rate is a critical sign of hyperkalemia, a serious condition that can lead to life-threatening cardiac arrhythmias. Stopping the infusion promptly is crucial to prevent further complications. The healthcare professional should inform the healthcare provider immediately for further evaluation and management. Choice A is incorrect because pain at the IV site is common and may not necessitate stopping the infusion. Choice C is incorrect as swelling at the IV site may indicate a local reaction but is not a reason to stop the infusion. Choice D is incorrect as an elevated blood pressure alone is not a direct indication to stop the infusion of IV potassium chloride.
