A nurse in an outpatient clinic is assessing a client who is pregnant for unsafe behaviors during pregnancy. Which of the following findings indicates a need for further evaluation?

Rationale: A. The client is doing 30 min of moderate exercise daily: Regular moderate exercise (e.g., walking, swimming) is recommended in pregnancy. It improves circulation, mood, and endurance for labor. B. The client last visited the dentist 4 months ago: Dental care is encouraged during pregnancy because hormonal changes increase the risk of gingivitis. A dental visit 4 months ago is appropriate. C. The client started working in a parking garage 3 months ago: Parking garages have poor ventilation and potential exposure to carbon monoxide (CO) from car exhaust, which can cause fetal hypoxia and developmental harm. The nurse should assess environmental safety and possibly recommend reassignment. D. The client is drinking 2.5 L of water per day: Adequate hydration is essential in pregnancy to maintain amniotic fluid volume and prevent dehydration.
