Final answer:
To combat constipation, a postpartum client should increase intake of high-fiber foods, drink plenty of water, and get regular exercise.
Step-by-step explanation:
The nurse should recommend that the postpartum client increase her intake of high-fiber foods to combat constipation. Insoluble fiber, which does not dissolve in water, increases the bulk of feces in the large intestine and helps keep food wastes moving through. Good sources of insoluble fiber include whole wheat, wheat bran, beans, and potatoes. Drinking plenty of water and getting regular exercise are also important factors in preventing constipation.
