1According to the Lipschitz anthropometric classification widely used in Argentine clinical practice for older adults (adultos mayores), what Body Mass Index (BMI / IMC) range defines a normal nutritional status (peso normal / eutrofia)?

A.22.0 to 27.0 kg/m²

B.18.5 to 24.9 kg/m²

C.25.0 to 29.9 kg/m²

D.20.0 to 25.0 kg/m²

Explanation: In older adults (>=60-65 years), physiological changes such as loss of height due to vertebral compression, sarcopenia, and altered fat distribution require adjusted BMI cutoffs. According to the Lipschitz criteria, a BMI <22 kg/m² indicates underweight (desnutrición/bajo peso), 22.0 to 27.0 kg/m² indicates normal weight (eutrofia), and >27.0 kg/m² indicates overweight/obesity.

2A 58-year-old patient admitted with a 3-week history of severe hyporexia, unintentional weight loss of 12% of habitual body weight, persistent diarrhea, subcutaneous fat loss over the triceps and temples, and mild ankle edema is evaluated using the Subjective Global Assessment (Valoración Global Subjetiva - VGS / SGA). What is the patient's nutritional category?

A.VGS Class A: Well nourished (Bien nutrido)

B.VGS Class C: Severely malnourished (Severamente desnutrido)

C.VGS Class B: Moderately malnourished or suspected malnutrition (Moderadamente desnutrido)

D.VGS Class D: Critical cachexia requiring immediate parenteral bypass

Explanation: The Subjective Global Assessment (VGS/SGA) stratifies patients into three categories: Class A (Well nourished), Class B (Moderately malnourished or suspected of malnutrition), and Class C (Severely malnourished). A weight loss greater than 10% in 6 months (especially >5% in recent weeks), continuous gastrointestinal symptoms, severe dietary reduction, physical signs of muscle/fat wasting, and edema categorize this patient definitively as VGS Class C.

3Why are visceral proteins such as serum albumin and prealbumin (transthyretin) considered unreliable indicators of acute nutritional status in critically ill or inflamed patients?

A.Their plasma concentrations increase dramatically during metabolic stress, leading to false-positive overestimations of nutritional reserves

B.They have an excessively long biological half-life of over 120 days, making them insensitive to short-term changes

C.They are negative acute-phase reactants whose hepatic synthesis decreases in response to systemic inflammation and proinflammatory cytokines regardless of nutrient intake

D.They are exclusively degraded by the kidneys, rendering their levels dependent only on glomerular filtration rate

Explanation: Serum albumin (half-life ~20 days) and prealbumin (half-life ~2-3 days) are negative acute-phase proteins. In the presence of inflammation, sepsis, trauma, or elevated C-reactive protein (CRP), hepatic protein synthesis shifts toward positive acute-phase reactants (CRP, ferritin, fibrinogen) while downregulating albumin and prealbumin synthesis; vascular permeability also causes transcapillary escape, making low levels markers of inflammatory severity rather than nutritional intake alone.

4In clinical anthropometric assessment, how is the Mid-Arm Muscle Circumference (Circunferencia Muscular del Brazo - CMB) calculated to assess somatic protein mass, and what variables are required?

A.CMB (cm) = Body weight (kg) - [3.1416 × Triceps skinfold (PCT, cm)]

B.CMB (cm) = Mid-arm circumference (CB, cm) + [3.1416 × Triceps skinfold (PCT, mm)]

C.CMB (cm) = [Mid-arm circumference (CB, cm) / Triceps skinfold (PCT, mm)] × 100

D.CMB (cm) = Mid-arm circumference (CB, cm) - [3.1416 × Triceps skinfold (PCT, cm)]

Explanation: Mid-Arm Muscle Circumference (CMB) estimates skeletal muscle mass (somatic protein compartment) by subtracting the subcutaneous fat layer from the total arm circumference using the formula: CMB (cm) = CB (cm) - [pi × PCT (cm)] or CMB (cm) = CB (cm) - [0.314 × PCT (mm)]. Triceps skinfold (PCT) measures adipose stores, while mid-arm circumference (CB) measures both bone, muscle, and fat.

5When applying the Nutritional Risk Screening 2002 (NRS-2002) tool to adult hospitalized patients, what total score threshold indicates that the patient is at nutritional risk and requires a formal nutritional care plan?

A.Total score ≥ 3

B.Total score ≥ 1

C.Total score ≥ 5

D.Total score ≥ 7

Explanation: The NRS-2002 evaluates both impaired nutritional status (0-3 points) and disease severity/metabolic stress (0-3 points), with an additional 1 point added for patients aged >=70 years. A total score >=3 indicates that the patient is at significant nutritional risk and warrants immediate initiation of specialized nutritional therapy.

6In Bioelectrical Impedance Analysis (BIA / Bioimpedanciometría), what does a low Phase Angle (Ángulo de Fase) reflect clinically in a hospitalized patient?

A.Severe dehydration with hypernatremia and elevated cellular resistance

B.Impaired cell membrane integrity, decreased body cell mass (masa celular corporal), and increased morbidity/mortality risk

C.Excessive skeletal muscle hypertrophy and optimal cellular hydration

D.Isolated elevation of extracellular fat without alterations in cell membrane capacitance

Explanation: The Phase Angle is derived from the arc-tangent of the ratio of Reactance (capacitance of cell membranes) to Resistance (fluid opposition to alternating current). A high phase angle indicates intact cell membranes and abundant body cell mass (BCM), whereas a low phase angle reflects cell death, disrupted membrane integrity, loss of intracellular mass, and altered hydration, correlating with higher clinical complications and mortality.

7A 26-year-old patient with Type 1 Diabetes uses carbohydrate counting (conteo de carbohidratos) with an Insulin-to-Carbohydrate Ratio (I:C / Ratio Insulina:Carbohidratos) of 1 unit of rapid-acting insulin per 15 g of carbohydrate, and an Insulin Sensitivity Factor (ISF / Factor de Corrección) of 40 mg/dL per unit with a target preprandial blood glucose of 100 mg/dL. If the patient's preprandial capillary glucose is 180 mg/dL and the planned meal contains 60 g of carbohydrates, what total prandial insulin bolus should be administered?

A.4 units

B.5 units

C.6 units

D.8 units

Explanation: The total bolus equals the food bolus plus the correction bolus. Food bolus = 60 g CHO / (15 g/unit) = 4 units. Correction bolus = (Current glucose - Target glucose) / ISF = (180 mg/dL - 100 mg/dL) / 40 mg/dL/unit = 80 / 40 = 2 units. Total bolus = 4 units + 2 units = 6 units.

8Which of the following dietary strategies is most effective for reducing postprandial glycemic excursions in patients with Type 2 Diabetes Mellitus?

A.Restricting daily water intake to less than 500 mL during main meals

B.Replacing all dietary carbohydrates with pure saturated animal fats and eliminating fiber

C.Consuming high glycemic index refined carbohydrates on an empty stomach to trigger rapid insulin spikes

D.Consuming foods rich in viscous soluble fiber (e.g., legumes, oats, psyllium) combined with low glycemic index complex carbohydrates

Explanation: Viscous soluble fibers form a gel matrix in the small intestine that delays gastric emptying and slows carbohydrate absorption, resulting in a blunted postprandial glucose spike. Choosing low glycemic index (GI) foods further improves overall glycemic control and insulin sensitivity in patients with Type 2 Diabetes.

9In line with the Guías Alimentarias para la Población Argentina (GAPA) and international consensus guidelines for arterial hypertension, what is the maximum recommended daily intake of sodium and salt (sodium chloride) for the general adult population?

A.Less than 2,000 mg of sodium per day (equivalent to less than 5 g of salt / NaCl)

B.Less than 4,000 mg of sodium per day (equivalent to 10 g of salt / NaCl)

C.Exactly 500 mg of sodium per day (equivalent to 1.25 g of salt / NaCl)

D.No restriction on sodium intake as long as potassium is supplemented

Explanation: WHO and Argentine national guidelines (MSAL / GAPA) recommend consuming less than 2,000 mg of sodium per day, which corresponds to less than 5 g of common table salt (NaCl, approximately one level teaspoon). In Argentina, the average consumption historically reached 10-12 g/day, making sodium reduction a primary public health target.

10A 52-year-old patient with primary hypercholesterolemia and an LDL-cholesterol of 175 mg/dL is prescribed medical nutrition therapy. Which dietary modification provides the most substantial reduction in plasma LDL-C levels?

A.Increasing dietary cholesterol to >600 mg/day while eliminating all polyunsaturated fatty acids

B.Limiting saturated fatty acids to <7% of total energy, eliminating industrial trans-fatty acids, and adding 2 g/day of plant phytosterols/stanols and soluble fiber

C.Replacing all dietary fats with high-fructose corn syrup and refined starches

D.Restricting dietary protein to <0.4 g/kg/day

Explanation: The cornerstone of nutritional therapy for lowering LDL-C includes restricting saturated fatty acids to <7% of daily caloric intake, eliminating trans fats, replacing them with monounsaturated (MUFA) and polyunsaturated (PUFA) fats, and incorporating 2-3 g/day of plant stanols/sterols along with 10-25 g/day of soluble fiber (which binds bile acids in the intestinal lumen).

About the Examen Integrado Nutrición Exam

The Examen Integrado de Residencias de la Salud para la disciplina de Nutrición is the official national competitive examination in Argentina used to select and rank graduates holding a Licenciatura en Nutrición for entry into post-graduate multidisciplinary hospital residency programs (Residencias del Equipo de Salud) across national hospitals, participating provincial healthcare systems, and the City of Buenos Aires (CABA). Regulated under Resolución Ministerial N° 555/2026 and coordinated by the Comité de Adhesión al Examen Integrado (CAEI) through the Dirección Nacional de Calidad y Desarrollo del Talento en Salud, the examination standardizes post-graduate recruitment through a unified, rigorous 100-question digital evaluation. The exam rigorously covers five core domains: adult clinical medical nutrition therapy and specialized artificial nutritional support (enteral, parenteral, ERAS protocols); maternal and pediatric nutrition (fetal growth curves, infant feeding, SAP growth standards, inborn errors of metabolism); public health nutrition and Argentine food policy (Guías Alimentarias para la Población Argentina - GAPA, Ley 27.642 de Etiquetado Frontal, national epidemiological surveys); hospital food service systems and bromatology (HACCP, BPM, foodborne pathogens such as STEC/SUH, Código Alimentario Argentino); and statutory healthcare legislation and professional ethics (Ley 24.301, Ley 26.529, end-of-life bioethics). This practice bank provides high-yield questions reflecting the official national examination blueprint.
