Therapeutic Diets on the NCLEX
Which diet for which condition: cardiac, renal, GI, dysphagia, post-op. The master map.
The NCLEX asks one thing about diets: match the diet to the condition. This is the map.
Cardiac diets
HF and hypertension get sodium restriction, usually 2 g/day. Hypertension also gets DASH: fruits, vegetables, whole grains, low-fat dairy. High cholesterol gets low saturated fat. The tell in a stem: canned soup, deli meat, or a salt shaker is always the wrong pick.
Renal diets
CKD restricts potassium, phosphorus, and sodium. Protein depends on stage: restricted pre-dialysis, increased on hemodialysis. Fluid restriction once urine output falls. This is the diet with the most moving parts, so it gets its own post.
Diabetic diet
Consistent carbohydrate intake, not carb elimination. Carbs spread evenly across meals to match insulin. No skipped meals on insulin or sulfonylureas.
GI diets
Low residue for acute diverticulitis and IBD flares. High fiber for constipation and diverticulosis between flares. Gluten-free for celiac. Bland, small, frequent meals for PUD and GERD; GERD also drops caffeine, alcohol, chocolate, peppermint, and late meals.
Texture-modified diets
Dysphagia gets pureed, minced, or soft foods with thickened liquids per the swallow evaluation. Nothing by mouth after stroke until a swallow screen clears the patient.
Post-op progression
Clear liquids → full liquids → soft → regular, advanced as tolerated. Post-gastrectomy adds the dumping syndrome diet: small meals, low simple carbs, liquids between meals.
Two more the NCLEX likes
Gout: low purine, so no organ meats, shellfish, or beer. MAOIs: low tyramine, so no aged cheese, cured meats, or fermented anything. The MAOI list is a drug-food interaction, not a disease diet, and it shows up constantly.
Frequently asked
Fastest way to study diets?
Learn the food lists, not just the diet names. Stems test whether a tray is correct, and that means recognizing individual foods.
Who prescribes the diet?
The provider orders it. The nurse verifies the tray matches the order, teaches, and catches errors. Wrong tray at the bedside is a classic stem.
