Final answer:
The nurse exemplifies perseverance by repeatedly irrigating the nasogastric tube until it is patent because this reflects continuous effort and determination in face of procedural challenges. This action is more aligned with the concept of perseverance than perfect attendance, course completion, or emotional support.
Step-by-step explanation:
The nurse is best demonstrating perseverance by: 3. Repeatedly irrigating the nasogastric tube until it is patent. Perseverance in the healthcare setting often refers to continuing effort to do or achieve something despite difficulties, failure, or opposition. The act of repeatedly irrigating the nasogastric tube until it is patent shows the nurse's determination and continuous effort to ensure the tube functions properly, which is directly related to patient care.
While having a perfect attendance record and completing a lengthy course on current chemotherapies certainly require perseverance as well, they are more indicative of personal commitment and professional development, respectively. Sitting with a client until she is ready to discuss why she is crying does demonstrate empathy and patience, but it is not as specific an example of perseverance as the act of ensuring a medical procedure (nasogastric irrigation) is successfully completed.
Relevant examples of perseverance in nursing may include rigorous study habits to maintain a high grade point average, ensuring all items are reviewed and properly accounted for during a procedure, and providing consistent care for patients with complex conditions, such as metastatic inflammatory breast cancer.
