Which intervention helps prevent constipation and straining after CABG?

• A. Avoid any laxatives
• B. Increase dietary fiber without supervision
• C. Encourage straining to have a bowel movement
• D. Administer stool softener or mild laxative as prescribed

Answer: (D)

Constipation prevention after CABG is important because opioid pain meds and reduced activity slow bowel movement, and straining can put stress on the healing sternum and compromise breathing. The best approach is to administer a stool softener or a mild laxative as prescribed, which keeps stools soft and easy to pass and reduces the need to strain. This directly addresses the risk of hard stools and minimizes chest wall pressure, helping comfort, respiration, and sternal healing. The other options don’t address the problem appropriately: avoiding laxatives lets constipation persist and can increase straining; increasing dietary fiber without guidance may not be safe or effective right away after surgery; encouraging straining would be harmful.
