Which artificial intelligence application in nutrition practice carries the HIGHEST risk of perpetuating health disparities?
Answer: Predictive algorithms trained on non-diverse population datasets
Algorithms trained on homogeneous datasets encode existing biases and produce less accurate or inequitable recommendations for underrepresented populations.
A client photographs meals for AI-assisted nutrient analysis. The PRIMARY limitation of image-recognition food logging compared to manual entry is:
Answer: Inaccuracy in estimating portion sizes from 2D images
Two-dimensional images lack depth information, making accurate volume and thus gram-weight estimation inherently imprecise for AI analysis.
Under the FTC Act, a nutritionist who promotes a branded app on social media must:
Answer: Disclose any material connection including free access or affiliate relationships
The FTC requires clear disclosure of any material connection—including free products, affiliate links, or consulting relationships—regardless of whether direct payment occurred.
A nutrition practice adopts a patient portal that auto-sends dietary recall reminders via SMS. Which communication standard BEST protects client privacy in this workflow?
Answer: Sending a secure link requiring portal login to view data
Sending a secure portal link ensures ePHI is accessed only by authenticated users, preventing exposure of health information in unencrypted SMS channels.
A digital nutrition intervention uses push notifications to prompt meal logging. According to behavioral science principles, which notification strategy BEST sustains long-term engagement?
Answer: Variable-ratio reinforcement with intermittent praise notifications
Variable-ratio reinforcement schedules produce the most durable behavior maintenance because unpredictable rewards sustain motivation more than predictable ones.
Which metric from electronic dietary assessment software BEST indicates dietary pattern quality for a client with metabolic syndrome?
Answer: Healthy Eating Index (HEI) score
The HEI scores diet quality against Dietary Guidelines for Americans benchmarks, capturing pattern quality across multiple food groups relevant to metabolic health.
When using telehealth for nutrition counseling, which non-verbal communication challenge is MOST unique to video visits compared to in-person sessions?
Answer: Loss of paralinguistic cues due to audio lag or compression
Audio compression and lag in video calls distort tone, pacing, and micro-pauses, degrading paralinguistic information that helps clinicians gauge client affect and comprehension.
