A pregnant patient who is a lacto-ovo vegetarian asks the nurse to help her plan a diet that includes adequate protein intake. What instruction should the nurse give?
 
  1. Because you don't eat meat, eggs, or dairy products, it's important to eat adequate plant-based proteins.
  2. To improve protein absorption, avoid simultaneous intake of animal protein and plant protein.
  3. Following a lacto-ovo vegetarian diet will require you to take a daily supplement of vitamin B12.
  4. In addition to eggs and dairy products, beans, peanut butter, and soy milk can be effective sources of plant-based proteins.
