Mixed Deck — All CDN Topics Flashcards

The Maillard reaction in food processing primarily affects which nutrients?

Answer: Proteins and carbohydrates, reducing lysine bioavailability

The Maillard reaction between reducing sugars and amino acids (especially lysine) during heating creates browning compounds and reduces the bioavailability of lysine.

In the context of CDN certification, what is the most important consideration when implementing renal & cardiac nutrition?

Answer: Ensuring alignment with established standards, stakeholder needs, and best practices

When implementing renal & cardiac nutrition, CDN professionals must ensure alignment with industry standards and stakeholder needs. Hasty implementation without proper planning often leads to compliance issues and suboptimal outcomes.

In the context of CDN certification, what is the most important consideration when implementing medical nutrition therapy?

Answer: Ensuring alignment with established standards, stakeholder needs, and best practices

When implementing medical nutrition therapy, CDN professionals must ensure alignment with industry standards and stakeholder needs. Hasty implementation without proper planning often leads to compliance issues and suboptimal outcomes.

What role does continuous improvement play in nutritional genomics & precision for CDN certified professionals?

Answer: It drives ongoing enhancement of practices, processes, and outcomes through systematic evaluation

Continuous improvement is fundamental to professional practice in nutritional genomics & precision, involving regular evaluation, feedback integration, and process enhancement to maintain high standards.

What does the term 'change talk' refer to in motivational interviewing?

Answer: The client's own statements about desire, ability, reasons, or commitment to change

Change talk refers to client statements that favor change, including desire, ability, reasons, need, and commitment — a key predictor of behavior change outcomes.

Which of the following best describes a key competency required for cultural competency in nutrition in CDN practice?

Answer: Strong analytical skills combined with effective communication and ethical judgment

CDN professionals working in cultural competency in nutrition need analytical skills to assess situations, communication skills to convey findings, and ethical judgment to make sound decisions.

A food label lists 0 g trans fat per serving, but the ingredients include 'partially hydrogenated oil.' What does this indicate?

Answer: The product may contain up to 0.5 g trans fat per serving due to FDA rounding rules

FDA labeling rules allow rounding to 0 g if trans fat content is less than 0.5 g per serving, so foods containing partially hydrogenated oils may still have small amounts.

Which lab finding is most indicative of severe malnutrition requiring immediate medical stabilization before outpatient eating disorder treatment?

Answer: Heart rate of 46 bpm

Bradycardia (heart rate below 50 bpm) is a medical emergency in anorexia nervosa and requires inpatient stabilization.

In a geriatric patient, which serum marker reflects short-term protein status better than albumin?

Answer: Prealbumin (transthyretin)

Prealbumin has a half-life of 2–3 days vs. albumin's 20 days, making it more sensitive to recent nutritional changes.

Dental erosion on the lingual surfaces of maxillary teeth is a clinical sign most consistent with:

Answer: Frequent self-induced vomiting

Gastric acid from self-induced vomiting erodes the lingual (tongue-side) surfaces of upper front teeth, a finding called perimolysis.

An older adult with stage 3 chronic kidney disease (CKD) and malnutrition requires protein guidance. Which approach is most appropriate?

Answer: Provide 1.0–1.2 g/kg/day and monitor renal function closely

Current evidence in non-dialysis CKD with malnutrition supports moderate protein intake of 1.0–1.2 g/kg/day with close monitoring, balancing nutritional rehabilitation against renal progression.

A night eating syndrome (NES) patient reports consuming >25% of daily calories after the evening meal. Which intervention is first-line?

Answer: Structured meal timing with earlier caloric distribution

Restructuring meal timing to distribute calories more evenly throughout the day addresses the core behavioral pattern of NES.

When a CDN professional encounters an unfamiliar challenge in eating disorder treatment, what is the recommended first course of action?

Answer: Research applicable standards, consult with subject matter experts, and document the approach

Professional practice requires a methodical approach to unfamiliar challenges: research the applicable standards, consult experts when needed, and document the reasoning for the chosen approach.

During prolonged fasting, which metabolic state predominates to spare muscle protein?

Answer: Ketosis

Ketosis allows the brain and other tissues to use ketone bodies as an alternative fuel, reducing the need to catabolize muscle protein for gluconeogenesis.

What is the most effective way to measure success in nutritional genomics & precision within CDN professional practice?

Answer: Use a combination of quantitative metrics, qualitative assessments, and stakeholder feedback aligned with defined objectives

Effective measurement combines multiple data sources — quantitative metrics, qualitative assessments, and stakeholder feedback — all aligned with clearly defined objectives for a comprehensive evaluation.

Which vitamin is added to milk in the United States primarily to prevent rickets in children?

Answer: Vitamin D

Vitamin D fortification of cow's milk has been standard in the US since the 1930s and is the primary public health strategy to prevent nutritional rickets.

A patient on total parenteral nutrition (TPN) develops hyperglycemia. What is the first recommended intervention?

Answer: Reduce dextrose concentration and initiate insulin protocol

Reducing dextrose content and starting an insulin protocol is the standard first-line management for TPN-associated hyperglycemia.

What is the most effective way to measure success in pediatric & geriatric nutrition within CDN professional practice?

Answer: Use a combination of quantitative metrics, qualitative assessments, and stakeholder feedback aligned with defined objectives

Effective measurement combines multiple data sources — quantitative metrics, qualitative assessments, and stakeholder feedback — all aligned with clearly defined objectives for a comprehensive evaluation.

In the Health Belief Model, 'perceived barriers' refer to which concept?

Answer: The obstacles a person believes exist that prevent healthy behavior

Perceived barriers are the individual's beliefs about the obstacles (cost, time, taste) that make healthy behavior difficult or impossible.

How can dietary guidelines improve public health?

Answer: By providing evidence-based nutrition recommendations

Dietary guidelines are developed by scientific experts and provide evidence-based recommendations for healthy eating patterns. They serve as a vital public health tool to educate individuals and populations on how to make food choices that promote health, prevent chronic diseases, and improve overall well-being. By offering clear, actionable advice, these guidelines empower people to adopt healthier lifestyles.
