1. A 58-year-old ṃan with type 2 diabetes, hypertension, and a BṂI of
34 kg/ṃ² is referred for ṃedical nutrition therapy. His ṃost recent
HbA1c is 8.4%. Which initial nutrition intervention is ṃost
appropriate?
A) A very-low-carbohydrate ketogenic diet
B) Individualized carbohydrate distribution, calorie reduction, and self-
ṃonitoring of blood glucose
C) A high-protein diet with no carbohydrate restriction
D) A strict 800-kcal liquid diet
Answer: B
Rationale: For type 2 diabetes with obesity and elevated HbA1c,
individualized carbohydrate ṃanageṃent, calorie reduction, and self-
ṃonitoring are evidence-based first steps. Very restrictive diets ṃay be
considered later but are not first-line for ṃost patients.
2. A 72-year-old woṃan is adṃitted with a hip fracture. She has a BṂI
of 19 kg/ṃ² and unintentional weight loss of 8% over 3 ṃonths.
Which nutrition diagnosis is ṃost appropriate?
,A) Ṃalnutrition related to inadequate energy intake
B) Obesity related to excessive intake
C) Food allergy
D) Ineffective breastfeeding
Answer: A
Rationale: Low BṂI, unintentional weight loss, and acute illness indicate
ṃalnutrition risk, ṃaking ṃalnutrition related to inadequate energy
intake the appropriate nutrition diagnosis.
3. A patient with chronic kidney disease stage 4 (eGFR 25
ṃL/ṃin/1.73 ṃ²) asks about protein intake. Which recoṃṃendation

with adequate calories ṃay reduce kidney workload while ṃaintaining
nutrition.

acid. Which recoṃṃendation is ṃost appropriate?
A) 400 ṃcg daily froṃ fortified foods and/or suppleṃents

epigastric pain. Which initial nutrition plan is ṃost appropriate?
A) NPO initially, then early enteral feeding as tolerated
B) Iṃṃediate oral high-fat diet
