ACBN Technology & Digital Applications 4 — Questions and Answers
Question 1: A nutritionist wants to integrate a gut microbiome sequencing report into a client's care plan. Which limitation MOST constrains clinical interpretation of consumer microbiome tests?
- Inability to detect Lactobacillus species
- Lack of standardized reference ranges and validated clinical cutoffs (Correct answer)
- High cost relative to blood panels
- Requirement for refrigerated sample shipping
Correct answer: Lack of standardized reference ranges and validated clinical cutoffs
Consumer microbiome tests lack agreed-upon normal ranges and clinical validation, making confident dietary prescriptions based solely on these results premature.
Question 2: Which feature of a nutrition-focused electronic health record (EHR) MOST directly reduces medication-nutrient interaction errors?
- Color-coded meal plan templates
- Integrated drug-nutrient interaction alert system (Correct answer)
- Automated billing code suggestion
- Secure client messaging portal
Correct answer: Integrated drug-nutrient interaction alert system
Built-in drug-nutrient interaction alerts flag clinically significant interactions at the point of care, reducing the cognitive burden on the practitioner.
Question 3: A client tracks macros using a barcode-scanning app and reports hitting targets, yet weight loss has stalled. The MOST likely technology-related explanation is:
- The app does not support micronutrient tracking
- Inaccurate food label data in the app's crowdsourced database (Correct answer)
- The app lacks a social sharing feature
- The client is using metric instead of imperial units
Correct answer: Inaccurate food label data in the app's crowdsourced database
Crowdsourced food databases contain significant user-submitted errors in serving sizes and nutrient values, leading to systematic calorie underestimation.
Question 4: Which digital literacy skill is MOST essential for a nutritionist evaluating health claims on a client-shared website?
- Ability to code in HTML
- Lateral reading to cross-check sources across credible platforms (Correct answer)
- Proficiency in social media algorithms
- Knowledge of website design principles
Correct answer: Lateral reading to cross-check sources across credible platforms
Lateral reading—opening multiple tabs to verify a source against outside references—is the most effective strategy professional fact-checkers use to evaluate online health claims.
Question 5: A remote client uses a smart scale that syncs body composition data to a shared dashboard. Bioelectrical impedance analysis (BIA) results are MOST affected by which factor the client controls?
- Time of year
- Hydration status at measurement (Correct answer)
- Brand of the scale
- Wi-Fi signal strength
Correct answer: Hydration status at measurement
BIA estimates body composition from electrical resistance through tissue, so hydration level directly alters conductivity and can shift body fat percentage readings by several percentage points.
Question 6: In a group telehealth nutrition program, breakout rooms are used for peer discussion. Which ethical principle is MOST at risk if the platform records sessions without explicit participant consent?
- Beneficence
- Autonomy (Correct answer)
- Justice
- Fidelity
Correct answer: Autonomy
Autonomy requires that clients make informed decisions about their participation, including whether their discussions are recorded, making undisclosed recording an autonomy violation.
Question 7: A dietitian builds a macro-tracking spreadsheet with conditional formatting to flag nutrient targets. This tool BEST exemplifies which use of technology in nutrition practice?
- Telehealth service delivery
- Clinical decision support through data visualization (Correct answer)
- Electronic health records management
- Digital marketing and client acquisition
Correct answer: Clinical decision support through data visualization
Conditional formatting transforms raw intake data into visual alerts that guide practitioner and client action, functioning as a low-tech form of clinical decision support.
