Question 1

What is the recommended protein intake (g/kg/day) for a healthy older adult (>65 years) to preserve muscle mass?

Accepted Answer

1.0–1.2 g/kg/day

Answer

Research supports 1.0–1.2 g/kg/day of protein for older adults to counter anabolic resistance and preserve lean body mass.

Question 2

A breastfed infant whose mother follows a strict vegan diet is at risk for deficiency of which vitamin that requires supplementation?

Accepted Answer

Vitamin B12

Answer

Vitamin B12 is found almost exclusively in animal products; vegan mothers have low B12 in breast milk, putting infants at risk for neurological damage.

Question 3

Which dietary modification is first-line for an older adult with dysphagia at risk of aspiration?

Accepted Answer

Texture-modified foods and thickened liquids per IDDSI framework

Answer

The IDDSI (International Dysphagia Diet Standardisation Initiative) framework provides evidence-based texture and liquid modification levels to reduce aspiration risk.

Question 4

Failure to thrive (FTT) in a 9-month-old is most commonly caused by:

Accepted Answer

Inadequate caloric intake

Answer

The majority of FTT cases are non-organic and result from inadequate caloric intake due to feeding difficulties, psychosocial issues, or improper formula preparation.

Question 5

Which nutrient deficiency is a major risk in elderly patients taking long-term proton pump inhibitors (PPIs)?

Accepted Answer

Vitamin B12

Answer

PPIs reduce gastric acid secretion needed to cleave B12 from food proteins, impairing absorption and leading to deficiency over time.
