Interest in international cuisines
Transportation availability and mobility limitations (Correct answer)
Social media usage patterns

Correct answer: Transportation availability and mobility limitations

Transportation availability and mobility limitations are critical access barriers for older adults, as reduced mobility can prevent them from reaching grocery stores or food assistance sites.

Question 2: A client repeatedly misses appointments and does not follow the agreed plan. The most professional communication approach is to:

Explore the client's barriers nonjudgmentally and adjust goals collaboratively (Correct answer)
Express disappointment to motivate behavior change
Reduce contact until the client shows more commitment
Threaten to terminate services at the next missed session

Correct answer: Explore the client's barriers nonjudgmentally and adjust goals collaboratively

Nonjudgmental exploration of barriers respects client autonomy and supports realistic, collaborative goal-setting.

Question 3: What is the recommended daily protein intake for recreational athletes seeking general health and fitness?

0.4–0.6 g/kg body weight
2.5–3.0 g/kg body weight
1.2–1.7 g/kg body weight (Correct answer)
0.8–1.0 g/kg body weight

Correct answer: 1.2–1.7 g/kg body weight

Recreational athletes generally need 1.2–1.7 g of protein per kg of body weight daily to support muscle maintenance and recovery.

Question 4: A patient receiving parenteral nutrition should have blood glucose monitored regularly primarily because PN solutions:

Contain high concentrations of dextrose that can cause hyperglycemia (Correct answer)
Are protein-free
Always cause hypoglycemia
Contain no carbohydrate

Correct answer: Contain high concentrations of dextrose that can cause hyperglycemia

The dextrose load in parenteral nutrition frequently causes hyperglycemia, which worsens infection risk and outcomes.

Question 5: Adverse events from dietary supplements should be reported by practitioners to which FDA system?

MedWatch (Correct answer)
OSHA Form 300
NPDB
VAERS

Correct answer: MedWatch

MedWatch is the FDA's safety reporting program for adverse events involving supplements, drugs, and medical products.
