Which type of research design provides the STRONGEST evidence when evaluating a digital nutrition intervention's effectiveness?
Answer: Randomized controlled trial with an active control group
A randomized controlled trial with an active comparator minimizes confounding and selection bias, providing the highest level of evidence for causal claims about intervention effectiveness.
A client's nutrition app uses a large language model (LLM) chatbot to answer dietary questions. Which risk MOST warrants practitioner oversight of LLM-generated nutrition advice?
Answer: Hallucination—generating plausible but factually incorrect nutrition information
LLMs can generate confident, coherent, but factually wrong statements (hallucinations), which in a clinical context could lead to harmful dietary decisions without practitioner review.
According to the Academy of Nutrition and Dietetics, a key ethical obligation when using social media for nutrition education is:
Answer: Clearly distinguishing professional opinion from evidence-based guidance
The Academy's code of ethics requires practitioners to accurately represent the evidence base, making transparency about the distinction between opinion and research mandatory.
A wearable device estimates a client's sleep duration at 7.5 hours, but the client reports feeling unrefreshed. Which digital metric should the nutritionist ALSO examine to assess sleep quality?
Answer: Heart rate variability (HRV) and sleep stage distribution
Sleep stage distribution and HRV during sleep reveal restorative sleep architecture; adequate total duration with poor HRV or minimal deep/REM sleep can explain non-restorative sleep.
Which data governance principle requires that a nutrition app collect only the specific personal data necessary for its stated function?
Answer: Data minimization
Data minimization, a core GDPR and privacy best-practice principle, mandates that only data strictly necessary for the service's purpose is collected, reducing privacy risk.
A nutritionist uses predictive analytics software to flag clients at risk of dropping out of a weight management program. The MOST appropriate use of this output is:
Answer: Prioritize proactive outreach and support for flagged clients
Predictive flags should trigger enhanced engagement strategies; they are decision-support tools that inform—but do not replace—individualized clinical judgment.
When a nutrition practice migrates client records to a new EHR, which step is MOST critical to protect data integrity?
Answer: Validating migrated data with reconciliation checks against source records
Reconciliation checks compare migrated records against originals to catch data loss, corruption, or mapping errors before the old system is decommissioned.
