Final answer:
A patient getting ready for surgery is most likely to need a low-fiber diet to reduce stool and digestion complications during the procedure.
Step-by-step explanation:
A low-fiber diet is typically recommended for individuals who need to minimize their fiber intake, often for medical reasons. In the provided options, b. a patient who is getting ready for surgery would most likely need a low-fiber diet. This is because a low-fiber diet can help reduce stool and ease digestion, which is important before certain medical procedures to minimize complications and ensure a clear surgical field. For the other options, a wheat allergy doesn't necessarily require a low-fiber diet but rather a gluten-free one; a patient in rehabilitation after a burn injury may need a high-protein, high-calorie diet to promote healing; and a patient who tolerates a clear liquid diet is usually in the beginning stages of transitioning back to solid foods and may or may not specifically require low fiber at this stage.
