Act as a seasoned poet with a background in healthcare to craft a heartfelt poem about a nurse. The poem should highlight the [compassion], [resilience], and [dedication] of nurses, using vivid imagery and emotional depth. Incorporate specific details like [late-night shifts], [comforting words], or [healing touch] to bring the scene to life. The tone should be [reverent and uplifting], celebrating the nurse's role as a guardian of health. Use metaphors or similes to compare the nurse to elements like [a lighthouse in a storm] or [a steady heartbeat]. Keep the structure flexible, allowing for free verse or a rhythmic pattern, but ensure it flows naturally. Aim for 12-16 lines that capture the essence of nursing with authenticity and grace.
