The nurse is caring for a client with diabetic ketoacidosis (DKA). Which laboratory result requires immediate intervention?

Correct Answer: D

Rationale: Corrected Rationale: An arterial blood pH of 7.30 indicates the client is in acidosis, which is a life-threatening condition in DKA. Immediate intervention is required to correct the acidosis and prevent further complications such as organ failure or coma. Blood glucose of 250 mg/dL is elevated but not an immediate threat to life in comparison to acidosis. Serum potassium of 3.5 mEq/L and serum sodium of 135 mEq/L are within normal ranges and do not warrant immediate intervention in the context of DKA.

Correct Answer: A

Rationale: A respiratory rate of 20 breaths per minute indicates effective oxygen therapy. In pneumonia, the respiratory rate typically increases due to the body's effort to improve oxygenation. Option B (pH of 7.35) is related to acid-base balance, not specifically indicating oxygen therapy effectiveness. Option C (oxygen saturation of 92%) is below the normal range (95-100%), suggesting the need for oxygen therapy. Option D (clear breath sounds) is a positive finding but not a direct indicator of oxygen therapy effectiveness.

Correct Answer: D

Rationale: The correct answer is 'D.' The client stating 'I may experience some neck swelling' does not indicate a need for further teaching since neck swelling is an expected side effect of radioactive iodine therapy. Choices A and B are correct statements as the client should avoid close contact with pregnant women and children for a few days due to radiation exposure, and dry mouth and taste changes are common side effects. Choice C is redundant with choice D, making D the correct answer.

Correct Answer: B

Rationale: A workshop on stress management techniques is the most engaging activity as it allows participants to actively participate, learn practical skills, and interact with others. This hands-on approach fosters engagement and provides attendees with tools they can directly apply in their lives. Choice A, a lecture, may be informative but lacks the interactive element that promotes engagement. Choice C, a panel discussion, might be informative but could be passive for attendees. Choice D, distributing brochures, is informative but lacks the interactive and engaging nature of a workshop.

Correct Answer: B

Rationale: In the context of addressing bullying among students, training for teachers on how to handle bullying incidents (Option B) is the most important component to include in the program developed by the school nurse. Teachers play a crucial role in identifying, preventing, and addressing bullying situations in schools. By providing teachers with specific training on how to recognize signs of bullying, how to intervene effectively, and how to support both the victim and the bully, the school can create a safer and more supportive environment for students. While education on the effects of bullying (Option A) is important for raising awareness among students, without teachers equipped to address incidents, the impact may be limited. A peer mentoring program (Option C) can be valuable in fostering positive relationships and support among students, but it may not directly address the immediate need for intervention and prevention of bullying. Similarly, a zero-tolerance policy for bullying (Option D) is essential but should be complemented by teacher training to ensure consistent enforcement and effective responses to incidents. In an educational context, emphasizing teacher training aligns with the idea of creating a comprehensive approach to bullying prevention and intervention that involves all stakeholders in the school community. By empowering teachers with the knowledge and skills to address bullying effectively, the school nurse's program can have a more significant and lasting impact on student well-being and school climate.
