Nutritional Risk in Pregnancy
Adolescents - only think of themselves Poverty Closely spaced pregnancies Previous poor fetal outcome Multi-fetal pregnancy Poor diet habits, resist change Use of tobacco, alcohol, or drugs Low Hgb or HCT
Listeriosis

Toxoplasmosis
causes: mental retardation, blindness, and epilepsy
avoid: raw meat and cat feces
Alcohol
- teratogenic
- damage is caused by fetal cell dehydration
- causes: mental retardation, learning disabilities, and fetal alcohol syndrome
- no known safe amount, AVOID ENTIRE PREGNANCY
Caffeine
- limit intake to 300 mg/day
- linked to miscarriages and low birth weight
