A pregnant patient is discussing nutrition and vitamin supplements with the nurse. Which statement by the patient indicates an understanding of the use of nutrition and supplements during pregnancy?
a. "I can get adequate folic acid by consuming foods fortified with synthetic folate."
b. "I need reduced amounts of vitamin C while pregnant to lower my risk of hemorrhage."
c. "I should take vitamin K so my baby won't be vitamin K deficient at birth."
d. "Excessive amounts of vitamin A (retinol) can cause birth defects in my baby."
ANS: D
Vitamin A in high doses can cause birth defects, so pregnant women should be cautioned about exceeding the UL and probably the RDA for vitamin A while pregnant. Pregnant women need to take 400 to 800 mg of supplemental folic acid in addition to that in food. Vitamin C deficiency, not excess, can lead to bleeding disorders. Maternal intake of vitamin K will not prevent infants from being born vitamin K deficient.
