Which statement shows a pregnant client needs further education regarding safe medications during pregnancy?

The statement indicating the need for further education is that Ex-Lax is preferred for bowel movements during pregnancy. This is because Ex-Lax, which contains the stimulant laxative sennosides, may not be the best choice for pregnant individuals. Stimulant laxatives can cause cramping and may lead to dependency if used excessively. Instead, safer alternatives such as bulk-forming laxatives (like psyllium) or stool softeners (like docusate sodium) are often recommended for managing constipation during pregnancy, as they are generally considered more effective and safer.

The other options represent safer choices that align with common recommendations for medication use during pregnancy. For example, acknowledging that certain antacids are acceptable for managing heartburn reflects an understanding of safe medications. Similarly, recognizing that Tylenol (acetaminophen) is generally safe for headache relief demonstrates knowledge about acceptable pain relief during pregnancy. The mention of Milk of Magnesia being acceptable while mineral oil is not shows an awareness of the differing safety profiles for laxatives, emphasizing the importance of cautious selection of medications throughout pregnancy.
