What should be done to prevent constipation in post-MI patients?

• A. Increase red meat intake
• B. Administer stool softeners
• C. Use stimulant laxatives routinely
• D. Avoid fiber

Answer: (B)

Constipation prevention in post‑MI patients is about avoiding straining, which can raise intrathoracic pressure and stimulate the heart in a dangerous way. Stool softeners reduce the effort needed to pass stool, keeping it soft and easier to move through the colon without pushing hard. This helps prevent episodes of straining that could worsen ischemia or trigger arrhythmias in someone recovering from a heart attack.

Avoiding fiber would actually help prevent constipation, so that choice isn’t suitable. Increasing red meat intake doesn’t address bowel habits and can contribute to harder stools over time. Routine stimulant laxatives can cause cramps, electrolyte disturbances, and dependency, making them less appropriate for regular prevention in this setting.
