Final answer:
Fluid volume excess in a 2-year-old may present with increased blood pressure, edema, and decreased urine output.
Step-by-step explanation:
When assessing a 2-year-old whose parent reports 'something is not quite right,' the nurse should associate increased blood pressure, edema, and decreased urine output with fluid volume excess. Fluid volume excess occurs when there is an abnormal accumulation of fluid in the body, leading to symptoms such as increased blood pressure, swelling of the tissues (edema), and reduced urine output.
