Diets for the NCLEX Exam

February 14, 2019 By Justine Buick 3 Comments

Diets for the NCLEX exam is an important topic. I also include the most common foods that contain the electrolytes, vitamins, and minerals. Each diet is therapeutic depending on what disease the client has. Here are the most common.

This post was updated June 4, 2020.

    • low fiber prevents diarrhea
  • High fiber diet

Breakdown of Foods

Try to break foods down into these groups:

  • Carbs
    • sugar and starches
    • mostly grains: but also milk, fruits, vegetables
    • whole grain carbs are good for you like oats and brown rice
    • refined carbs are bad for you like cookies and cake
    • too many refined carbs increases risk of heart disease and diabetes
  • Fats
    • good fats: unsaturated like olive oil and nuts
    • bad fats: saturated like butter, fat from red meat
    • too many bad fats increases risk of cardiac disease
  • Proteins
    • meat, dairy, beans & rice
    • good for healing

Vitamins

    • dark green leafy vegetables, meat, legumes, nuts and eggs
    • prevents neural tube defects and folate-deficiency anemia

    • good for preventing osteoporosis
  • Sodium
    • “salty things”, bacon, canned food, processed food, table salt, bread, soy sauce

      That sounds like one of the healthiest diets! I don’t think doctors are “prescribing” that diet, but as nurses we should probably be aware of it. Thanks Kelly!
