A nurse is caring for a client who is on bedrest and is experiencing constipation. Which of the following interventions should the nurse implement?

A. Cold fluids are less effective in stimulating bowel movements compared to warm fluids. Warm fluids tend to promote peristalsis and help relieve constipation, making cold fluids a less appropriate option. B. A low-fiber diet would worsen constipation. High-fiber foods are more effective in promoting bowel regularity by adding bulk to the stool, facilitating easier passage. C. Mineral oil is not a first-line treatment for constipation due to the risk of nutrient malabsorption and potential complications like aspiration in bedridden clients. It should be used cautiously. D. Increasing fluid intake is an essential intervention for constipation, especially for clients on bedrest. Proper hydration softens stools and helps in promoting bowel movements, reducing the risk of constipation.
