A client reports passing 2 to 3 small, hard stools per week since being placed on a low-residue diet three months ago. Which type of laxative should the nurse expect the healthcare provider to recommend first?

A. Emollient: Emollient (stool softener) laxatives like docusate sodium help moisten stool but do not significantly increase stool volume or stimulate bowel movement. They are gentle but typically insufficient for long-term, low-frequency constipation. B. Osmotic: Osmotic laxatives draw water into the bowel to promote peristalsis. They are effective but may cause electrolyte imbalances if used chronically. These are often reserved for when bulk-forming agents are ineffective. C. Bulk-forming: Bulk-forming laxatives such as psyllium are typically the first-line recommendation for chronic constipation. They mimic dietary fiber by absorbing water, increasing stool bulk, and promoting regular bowel movements with minimal side effects. D. Stimulant: Stimulant laxatives like senna or bisacodyl are stronger agents that promote bowel motility but can cause dependency if used long-term. They are not recommended as first-line therapy for chronic constipation related to diet.
