Nursing implications

Nursing assessment

  • Assess for abdominal distention, presence of bowel sounds, and usual pattern of bowel function.
  • Assess color, consistency, and amount of stool produced.

Potential Nursing Diagnoses

Constipation (Indications)

Implementation

  • This medication does stimulate intestinal peristalsis.
  • Oral: Administer with a full glass of water or juice preferably in the evening.
    • Do not administer within 2 hr of other laxatives, especially mineral oil. May cause increased absorption.

Patient/Family Teaching

  • Advise patients that laxatives should be used only for short-term therapy. Long-term therapy may cause electrolyte imbalance and dependence.
  • Encourage patients to use other forms of bowel regulation, such as increasing bulk in the diet, increasing fluid intake (6–8 full glasses/day), and increasing mobility. Normal bowel habits are variable and may vary from 3 times/day to 3 times/wk.
  • Instruct patients with cardiac disease to avoid straining during bowel movements (Valsalva maneuver).
  • Advise patient not to use laxatives when abdominal pain, nausea, vomiting, or fever is present.

Evaluation/Desired Outcomes

  • A soft, formed bowel movement, usually within 6–24 hr.
