Combine shrimp, mixed vegetables, and water in a skillet over medium-high heat; cook and stir until vegetables are cooked through and shrimp are hot, about 5 minutes.

Bring a small pot of water to a boil. Cook ramen noodles in the boiling water until soft, 2 to 3 minutes; drain. Add noodles to vegetable mixture. Stir seasoning from ramen noodles, soy sauce, garlic powder, and ground ginger into the vegetable and noodle mixture; toss to combine. Cook and stir until hot, about 1 minute.
