Question 1 of 3

A client with gout is admitted with an acutely painful, red, swollen great toe. Which dietary instruction should the nurse provide to help prevent future attacks?

What is gluten-free diet?

In celiac disease, gluten triggers an immune reaction that damages the small intestine and impairs nutrient absorption. Strict, permanent avoidance allows the intestinal villi to heal.

Key points to remember

  • Gluten is found in wheat, barley, rye, and many processed foods, sauces, and beer.
  • The classic memory aid is to avoid BROW: barley, rye, oats with risk of cross-contamination, and wheat.
  • Naturally gluten-free foods include rice, corn, quinoa, potatoes, fruits, vegetables, meat, fish, and eggs.
  • Even small amounts of gluten and cross-contamination can cause intestinal damage.
  • Untreated celiac disease leads to malabsorption, anemia, and deficiencies in iron, folate, calcium, and vitamin D.

Nursing priorities

  1. Teach the patient to read labels for hidden gluten in additives, sauces, and processed foods.
  2. Educate on preventing cross-contamination with separate utensils and toasters.
  3. Monitor for resolution of diarrhea, bloating, and weight loss as the gut heals.
  4. Assess for and address nutritional deficiencies such as iron and folate.
  5. Reinforce that the diet is lifelong even after symptoms resolve.

Labs & values

Hemoglobin12 to 16 g/dL women and 14 to 18 g/dL men
Ferritin and iron studies for anemia
Tissue transglutaminase IgA (tTG-IgG only if IgA-deficient) antibody used in diagnosis and monitoring
Vitamin D and folate levels

Patient teaching

  • Read every food label and watch for wheat, barley, rye, malt, and brewer's yeast.
  • Avoid oats unless certified gluten-free due to cross-contamination.
  • Use separate cutting boards, toasters, and utensils to avoid cross-contact.
  • This diet is for life; even small slips can damage your intestine.

Red flags: report now

  • Persistent diarrhea, weight loss, and steatorrhea despite the diet suggest ongoing gluten exposure or another problem.
  • Never assume the diet is temporary; lifelong adherence is required for celiac disease.
  • Signs of severe malabsorption or anemia should be reported and worked up.
