The nurse is caring for different 4 clients. Which of the following client assessments would cause the most concern for the nurse?

Choice A reason: Green liquid stool in a colostomy pouch is often benign, resulting from diet (e.g., green vegetables) or medications. In an 80-year-old, this is not immediately concerning unless accompanied by systemic symptoms like fever or pain. Choice B reason: Slight bleeding when wiping a colostomy is common, especially in an 18-year-old with a new stoma, due to fragile tissue. It warrants monitoring but is not as concerning as signs of poor stoma viability. Choice C reason: A red, moist colostomy in a 45-year-old indicates a healthy, well-perfused stoma, which is normal post-placement. This is an expected finding and does not raise immediate concern compared to abnormal stoma appearance. Choice D reason: A pale pink/purple colostomy suggests poor perfusion or ischemia, especially in a 55-year-old. This abnormal color, even with moisture, indicates potential stoma necrosis, requiring urgent assessment to prevent complications like tissue death or infection.
