A confident cartoon-style nurse standing proudly, wearing scrubs with bold red, white, and blue accents. She has a stethoscope shaped like a star, patriotic sunglasses, and a messy bun tied with a glittery USA flag bow. The background bursts with vibrant 4th of July fireworks, glowing glitter stars, and sparkles in red, white, and blue. Her pose is strong and heroic, symbolizing care and country. Seamless edge-to-edge layout, ultra-vibrant color saturation, high-resolution digital art, no flowers.
