Correct Answer: C

Rationale: The correct answer is C. Checking the blood pressure of a 2-hour postoperative client is a task that can be safely delegated to an unlicensed assistive personnel (UAP) as it falls within their scope of practice. This task is routine and does not require specialized nursing knowledge or critical decision-making. Options A, B, and D involve tasks that require a higher level of training and critical thinking beyond the scope of a UAP. Taking a history, adjusting tube feeding rates, and monitoring a client receiving chemotherapy are responsibilities that should be performed by licensed healthcare providers who have the necessary skills and training.

Correct Answer: C

Rationale: The correct answer is C. Skipping meals to lose weight may indicate an eating disorder or significant distress, which can have serious health implications. This behavior raises concerns about the adolescent's physical and mental well-being. The nurse should prioritize addressing potential eating disorders and body image issues in this situation. Choices A, B, and D, while important, do not pose an immediate risk to the adolescent's health or well-being compared to the potential consequences of disordered eating behavior.

Rationale: Taking an iron supplement with milk can decrease its absorption, indicating a need for further teaching.

Correct Answer: A

Rationale: In a client with pneumonia, assessing breath sounds is crucial as it provides immediate information about the client's respiratory status. Changes in breath sounds could indicate complications like fluid accumulation or worsening pneumonia. While the client's history of smoking (Choice B), current medication list (Choice C), and family history of respiratory illness (Choice D) are important factors to consider, they are not as urgent or directly related to the client's immediate condition as assessing breath sounds.

Correct Answer: A

Rationale: Erythema on pressure points indicates potential skin breakdown due to prolonged immobility. It requires immediate intervention to prevent pressure ulcers. Lower-extremity pulse strength of 2+ is a normal finding, indicating adequate peripheral perfusion. Fluid intake of 3,000 mL per day is within the normal range and promotes hydration. A bowel movement every other day is a reasonable frequency for some individuals and does not necessarily indicate a need for immediate intervention in this scenario.
