Final answer:
The nurse should empathize with the patient's concerns about swimming with a colostomy and offer information about managing the situation rather than discouraging activity. Option b is correct.
Step-by-step explanation:
The appropriate response for the nurse to give to a client who is concerned about swimming with a new colostomy is: "I understand your concerns; let's discuss ways to manage this." This response is empathetic and opens the door for providing the client with information about how to engage in swimming and other water activities safely with a colostomy.
While care must be taken to protect the stoma and ensure the colostomy bag is secure, many colostomy patients continue to lead active lives, including swimming. The nurse can provide guidance on using waterproof colostomy covers, checking the seal of the pouch, and other tips for maintaining an active lifestyle post-surgery.
