Which intervention should a nurse recommend for a pregnant client with intermittent constipation?

The chosen intervention of recommending the pregnant client to drink 2 liters of water per day is particularly effective in addressing constipation. Hydration plays a crucial role in maintaining intestinal health and promoting regular bowel movements. Adequate fluid intake helps soften the stool, making it easier to pass and reducing the likelihood of constipation.

While increasing dietary fiber intake and engaging in daily exercise routines are also beneficial for relieving constipation, hydration is foundational. Fiber requires sufficient water to properly function in the digestive system; without enough fluid, increased fiber can sometimes lead to further constipation or discomfort.

The option of taking over-the-counter laxatives weekly may not be recommended as a first-line approach in pregnancy due to potential risks and side effects associated with their use. This could lead to dependency or other digestive issues if relied upon too frequently.

In summary, promoting water intake aligns with best practices for managing constipation during pregnancy, making it the most suitable recommendation in this scenario.
