Question

Why should the nurse instruct a pregnant patient to take only prescribed prenatal vitamins?

a) Over-the-counter vitamins may cause allergic reactions
b) Prescription vitamins are more expensive
c) Generic vitamins are equally effective
d) Controlled dosages prevent excessive intake of certain nutrients

Answer 1

Pregnant patients should take only prescribed prenatal vitamins to ensure controlled dosages and prevent nutrient toxicity, as well as to provide essential nutrients like folic acid for fetal development.

Step-by-step explanation:

The nurse should instruct a pregnant patient to take only prescribed prenatal vitamins because controlled dosages prevent excessive intake of certain nutrients. Over-the-counter vitamins may not have the proper dosages that are needed during pregnancy and could lead to toxicity, such as an excessive amount of vitamin A, which can cause liver toxicity and other symptoms. Prescription prenatal vitamins are specifically formulated to provide the appropriate amounts of vitamins and minerals, like folic acid, which are crucial for the healthy development of the fetus and help prevent birth defects.
