Premium Exam Tested And Verified
Subject Area Gerontological Nutrition / CDR Gerontology
Description This exam assesses advanced knowledge in gerontological nutrition, including
age-related physiological changes, disease-specific dietary management,
pharmacology interactions, ethical considerations, and evidence-based

implications.
2. Design and evaluate medical nutrition therapy for chronic conditions prevalent
in older adults.
3. Integrate pharmaconutrition and drug-nutrient interaction knowledge into
clinical practice.
4. Apply ethical and evidence-based decision-making in gerontological nutrition
care.
Accreditation Meets CDR (Commission on Dietetic Registration) specialty certification
standards for Gerontological Nutrition and US university graduate-level
accreditation.

,1. In older adults with sarcopenia, which of the following amino acid profiles in a
protein supplement has been shown to maximally stimulate muscle protein synthesis
when combined with resistance exercise?
A. A low-leucine, high-arginine blend with added glutamine
B. A high-leucine, balanced essential amino acid mix with a leucine threshold of ~3 g per
dose
C. A high-tryptophan, low-branched-chain amino acid formula
D. A collagen peptide supplement with high glycine and proline content
Answer: B. A high-leucine, balanced essential amino acid mix with a leucine
threshold of ~3 g per dose
Leucine is a key activator of the mTOR pathway; a threshold of ~3 g leucine per meal is
needed to stimulate muscle protein synthesis in older adults. Low-leucine options (A) or
collagen (D) lack sufficient leucine; tryptophan (C) does not directly stimulate muscle
synthesis.
2. A 78-year-old male with stage 3 chronic kidney disease (eGFR 38 mL/min/1.73
m²) and type 2 diabetes is being evaluated for nutritional management. Which of the
following dietary interventions is most appropriate to slow disease progression while
minimizing malnutrition risk?
A. Protein restriction to 0.6 g/kg body weight per day with strict phosphorus limitation
B. Protein intake of 1.0–1.2 g/kg body weight per day with emphasis on plant-based sources
and phosphorus binders as needed
C. High-protein diet (1.5 g/kg/day) to preserve muscle mass, with liberal phosphorus intake
D. Ketogenic diet with very low carbohydrate and moderate protein (0.8 g/kg/day)
Answer: B. Protein intake of 1.0–1.2 g/kg body weight per day with emphasis on
plant-based sources and phosphorus binders as needed
In stage 3 CKD, moderate protein restriction (0.8-1.0 g/kg) is recommended to reduce
nephron workload while avoiding malnutrition. Plant-based proteins offer additional
benefits. Option A risks malnutrition; C may accelerate renal decline; D is not
evidence-based for CKD.

,3. A 74-year-old female with osteoporosis is prescribed bisphosphonate therapy.
Which of the following statements regarding the interaction between calcium
supplementation and bisphosphonate absorption is correct?
A. Calcium supplements should be taken simultaneously with bisphosphonates to enhance
bone mineral density gains.
B. Calcium chelates bisphosphonates in the gut, reducing absorption; they must be separated
by at least 30-60 minutes.
C. Vitamin D, not calcium, interferes with bisphosphonate absorption; calcium is safe to
co-administer.
D. Bisphosphonates require an acidic gastric pH; calcium carbonate can be taken together if
given with food.
Answer: B. Calcium chelates bisphosphonates in the gut, reducing absorption; they
must be separated by at least 30-60 minutes.
Bisphosphonates form insoluble complexes with calcium, preventing absorption.
Guidelines recommend taking bisphosphonates on an empty stomach with plain water
and waiting at least 30-60 minutes before consuming calcium.
4. A geriatric patient with advanced dementia and dysphagia is receiving thickened
liquids. Which of the following best describes the primary physiological rationale for
using nectar-thick versus honey-thick consistencies?
A. Nectar-thick liquids have lower viscosity, reducing aspiration risk more effectively than
honey-thick.
B. Honey-thick liquids require greater pharyngeal muscle force to propel the bolus,
increasing aspiration risk in weak patients.
C. Nectar-thick liquids are easier to swallow but may not adequately protect the airway in
patients with poor laryngeal closure.
D. Honey-thick liquids are always preferred because they completely eliminate aspiration in
all patients.
Answer: C. Nectar-thick liquids are easier to swallow but may not adequately
protect the airway in patients with poor laryngeal closure.
Nectar-thick (mildly thick) liquids are less viscous and may still penetrate the airway if
laryngeal closure is inadequate; honey-thick (moderately thick) provides more
protection but requires better oral control. There is no one-size-fits-all, and individual
assessment is key.

, 5. Which of the following best describes the role of the Mini Nutritional Assessment
(MNA) in identifying malnutrition risk in community-dwelling older adults?
A. It is a screening tool validated for use in acute care but not in community settings.
B. It combines anthropometric, global, dietary, and subjective assessments to classify
nutritional status.
C. It relies solely on biochemical markers such as serum albumin and prealbumin.
D. It is designed to diagnose specific micronutrient deficiencies rather than overall
malnutrition.
Answer: B. It combines anthropometric, global, dietary, and subjective
assessments to classify nutritional status.
The MNA includes four components: anthropometric measurements (BMI, calf
circumference), global assessment (lifestyle, medication), dietary questionnaire (meal
frequency, protein/fruit intake), and self-perceived health. It is validated for
community-dwelling elderly, not just acute care.
6. In older adults with heart failure and preserved ejection fraction (HFpEF), which
dietary pattern has the strongest evidence for improving functional status and
quality of life?
A. Very low sodium diet (<1.5 g/day) combined with fluid restriction
B. Mediterranean diet supplemented with omega-3 fatty acids, emphasizing moderate
sodium reduction
C. High-protein, low-carbohydrate diet to promote weight loss
D. DASH diet with strict sodium <2.3 g/day and limited potassium intake
Answer: B. Mediterranean diet supplemented with omega-3 fatty acids,
emphasizing moderate sodium reduction
The Mediterranean diet, rich in polyphenols and unsaturated fats, reduces
inflammation and improves endothelial function in HFpEF. Sodium restriction is less
emphasized than in HFrEF; fluid restriction is not routinely recommended.
High-protein diets may increase cardiac workload.
