The nurse, working on the maternity unit, receives a call from a pregnant woman asking how she can know whether a medication is safe to take while pregnant. What is the nurse's best response?
- A. You can take any drug indicated as a Category A.
- B. No medications should be taken during pregnancy.
- C. Never take medication until you receive approval from your health care provider.
- D. Most medications are safe but you need to weigh benefit against risk.
Correct Answer: C
Rationale: The best response to a pregnant woman asking about medication usage is to talk with her obstetric practitioner because the best advice will come from someone who knows their health and pregnancy history. While Category A drugs have no known risk, they may be contraindicated by the woman's health condition or pregnancy issues and many pregnant women would not know what it means to be a Category A drug. Medications can be helpful during pregnancy if taken safely and appropriately. Although risk benefit needs to be weighed, it should occur with advice from the obstetric practitioner.
