Question 1

Which artificial intelligence application in nutrition practice carries the HIGHEST risk of perpetuating health disparities?

Accepted Answer

Predictive algorithms trained on non-diverse population datasets

Answer

Algorithms trained on homogeneous datasets encode existing biases and produce less accurate or inequitable recommendations for underrepresented populations.

Question 2

A client photographs meals for AI-assisted nutrient analysis. The PRIMARY limitation of image-recognition food logging compared to manual entry is:

Accepted Answer

Inaccuracy in estimating portion sizes from 2D images

Answer

Two-dimensional images lack depth information, making accurate volume and thus gram-weight estimation inherently imprecise for AI analysis.

Question 3

Under the FTC Act, a nutritionist who promotes a branded app on social media must:

Accepted Answer

Disclose any material connection including free access or affiliate relationships

Answer

The FTC requires clear disclosure of any material connection—including free products, affiliate links, or consulting relationships—regardless of whether direct payment occurred.

Question 4

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?

Accepted Answer

Sending a secure link requiring portal login to view data

Answer

Sending a secure portal link ensures ePHI is accessed only by authenticated users, preventing exposure of health information in unencrypted SMS channels.

Question 5

A digital nutrition intervention uses push notifications to prompt meal logging. According to behavioral science principles, which notification strategy BEST sustains long-term engagement?

Accepted Answer

Variable-ratio reinforcement with intermittent praise notifications

Answer

Variable-ratio reinforcement schedules produce the most durable behavior maintenance because unpredictable rewards sustain motivation more than predictable ones.
