A. The client started working in a parking garage 3 months ago: Working in a parking garage can increase exposure to carbon monoxide and other exhaust fumes, which can be harmful to both the pregnant client and the fetus. Prolonged inhalation of these toxins may reduce oxygen delivery and contribute to complications, making this finding a priority for further evaluation. B. The client is doing 30 min of moderate exercise daily: Moderate exercise is recommended during pregnancy as it improves circulation, reduces stress, and supports healthy weight gain. This behavior is considered safe and beneficial unless otherwise contraindicated by the provider. C. The client is drinking 2.5 L of water per day: Adequate hydration is essential during pregnancy to support amniotic fluid levels, circulation, and kidney function. A daily intake of 2.5 liters is appropriate and aligns with recommended guidelines for pregnant clients. D. The client last visited the dentist 4 months ago: Routine dental care is important during pregnancy due to increased risk of gingivitis, but a dental visit 4 months ago does not indicate an unsafe behavior. Continuing regular appointments every 6 months is generally sufficient unless specific concerns arise.
