Why is “play” an important part of childhood?

Review the case study and answer the following questions.
Case Study: Bobby, a 13-year-old male, was hospitalized following a perforated appendix that required surgery. Bobby has an open wound requiring dressing changes twice daily. He is currently on contact precautions for a methicillin resistant staphylococcus aureus (MRSA) infection. The estimated date of discharge is five-to-ten-days post-op and will include long-term antibiotics and wound care.
The nurse notes on the assessment- Previously Bobby was talkative and related his enthusiasm for school and upcoming science competitions. However, today, he was withdrawn and stated, “I’m just tired”.

What are the impacts when an adolescent is separated from their peer group?
How should the nurse arrange for visitation and playtime during Bobby’s hospitalization and isolation?
What concerns with body image would the nurse anticipate?
