Final answer:
A 4-year-old child should be able to cut outlined shapes using scissors due to advanced fine motor skills and should show enhanced cognitive and social development.
Step-by-step explanation:
The developmental milestones a nurse should expect to observe in a 4-year-old child during a well-child visit include advanced motor skills like cutting outlined shapes using scissors. At this age, children have developed fine motor skills that allow them to handle tools like scissors with better control and should be able to cut simple shapes out of paper. They are also able to grip a crayon with a tripod grasp, and their cognitive and social abilities are marked by burgeoning curiosity, as well as the ability to ask numerous questions and speak in almost entirely intelligible sentences.
