Final answer:
The nurse should advise the patient to follow a high-fiber diet and drink plenty of fluids to manage diverticulosis effectively.
Step-by-step explanation:
The nurse's most appropriate response to a patient newly diagnosed with diverticulosis and voicing concerns about future complications would be to recommend following a high-fiber diet. Eating a balanced diet that is high in fiber and low in fat can help prevent complications and manage the condition effectively. Fiber-rich foods such as whole grains, fruits, vegetables, and legumes can promote regular bowel movements and prevent further problems.
In addition to a high-fiber diet, it is important for the patient to drink plenty of fluids to help soften the stool and prevent constipation. Staying hydrated also supports overall digestive health. While it is true that some foods with small particles, such as nuts, popcorn, and foods with seeds, may pose a risk of becoming lodged in the diverticula and causing inflammation, it is generally not necessary to avoid them altogether.
