Mixed Deck — All CSP Topics Flashcards

A dietitian is counseling an adolescent athlete with relative energy deficiency in sport (RED-S). Which finding most directly confirms inadequate energy availability?

Answer: Amenorrhea lasting >3 months

Functional hypothalamic amenorrhea resulting from low energy availability is a hallmark clinical indicator of RED-S in female athletes.

A 6-month-old on continuous nasogastric tube feeding develops diarrhea and abdominal distension. Which intervention should be assessed first?

Answer: Evaluate formula concentration, rate, and contamination, and consider reducing infusion rate

Diarrhea and distension during tube feeding first require systematic evaluation of formula concentration, infusion rate, and hygienic preparation to identify a correctable cause.

Which of the following is a recognized consequence of catch-up growth occurring too rapidly in a severely malnourished infant?

Answer: Refeeding syndrome with electrolyte disturbances

Rapid refeeding of severely malnourished children can cause refeeding syndrome, characterized by dangerous shifts in phosphate, potassium, and magnesium as anabolic processes resume, potentially causing cardiac and neurologic complications.

Which amino acid becomes conditionally essential in infants with metabolic stress or prematurity?

Answer: Glutamine

Glutamine becomes conditionally essential during metabolic stress and prematurity due to increased demand and insufficient endogenous synthesis.

A 3-year-old child's mid-parental height target is calculated at the 60th percentile. The child is currently at the 15th percentile for height. Which evaluation is most warranted?

Answer: Bone age radiograph and growth hormone evaluation

A significant discrepancy between a child's current height percentile and the mid-parental target warrants investigation including bone age and endocrine evaluation to rule out growth hormone deficiency or other pathology.

Refeeding syndrome is most likely to occur in which pediatric patient?

Answer: A severely malnourished adolescent restarting nutrition support after prolonged starvation

Refeeding syndrome occurs in severely malnourished individuals when nutrition is reintroduced, causing shifts in phosphate, potassium, and magnesium into cells.

A hospitalized 8-year-old requires nasogastric tube feeding. Which formula characteristic is most appropriate to prevent aspiration complications?

Answer: Continuous low-rate delivery

Continuous low-rate infusion reduces gastric residual volume and minimizes aspiration risk in children at risk.

In Certified Specialist in Pediatric Nutrition, what role does professional ethics & legal compliance play in ensuring client/stakeholder satisfaction?

Answer: It builds trust through demonstrated competence and consistency

Professional Ethics & Legal Compliance builds trust through demonstrated competence and consistency, which directly contributes to stakeholder satisfaction and confidence in the CSP professional.

When transitioning a preterm infant from parenteral to enteral nutrition, what is the recommended minimum enteral intake considered 'trophic' or 'minimal enteral feeding'?

Answer: 10-20 mL/kg/day

Trophic feeds of 10-20 mL/kg/day promote gut maturation without imposing significant metabolic demands on preterm infants.

Which quality improvement method is most applicable to communication & interprofessional collaboration in Certified Specialist in Pediatric Nutrition?

Answer: Plan-Do-Check-Act (PDCA) continuous improvement cycle

The PDCA cycle is widely recognized as the most effective quality improvement method, allowing CSP professionals to systematically improve communication & interprofessional collaboration practices.

According to current AAP guidance on early allergen introduction, which statement is MOST accurate?

Answer: Early introduction of peanut products at 4–6 months may reduce peanut allergy risk in high-risk infants

The LEAP trial and subsequent guidelines support early introduction of peanut products around 4–6 months in high-risk infants (severe eczema or egg allergy) to reduce the risk of peanut allergy.

Energy requirements per kilogram of body weight are highest during which period of childhood?

Answer: Infancy (0–6 months)

Infants have the highest energy requirements per kilogram (~100–120 kcal/kg/day) relative to body weight due to the extremely rapid rate of growth and high metabolic rate during the first 6 months of life.

What is the role of vitamin D in pediatric bone health?

Answer: Essential for calcium absorption and bone health

Vitamin D is crucial for pediatric bone health because it regulates calcium and phosphate levels in the body. It facilitates the absorption of calcium from the gut, which is essential for the mineralization and strength of growing bones. Without adequate vitamin D, children can develop conditions like rickets, characterized by soft and weak bones.

Which of the following best describes a key competency required for communication & interprofessional collaboration in CSP certification?

Answer: Critical thinking and evidence-based decision making

Critical thinking and evidence-based decision making is essential for communication & interprofessional collaboration, as professionals must analyze situations and apply knowledge appropriately.

A 10-year-old with type 1 diabetes presents with recurrent hypoglycemia at night. Which dietary strategy is most appropriate?

Answer: Provide a bedtime snack with complex carbohydrates and protein

A bedtime snack combining complex carbohydrates and protein slows glucose release overnight, reducing nocturnal hypoglycemia risk.

Galactagogues are substances used to increase milk supply. Which of the following is considered a pharmacologic galactagogue sometimes used in lactating women?

Answer: Domperidone

Domperidone is a dopamine antagonist that increases prolactin levels and is used as a pharmacologic galactagogue, though it is not FDA-approved in the US for this purpose.

An infant with galactosemia must avoid which primary dietary component?

Answer: Lactose

Galactosemia requires elimination of lactose (which contains galactose) because the enzyme needed to metabolize galactose is deficient.

How does celiac disease affect pediatric nutrition?

Answer: Causes malabsorption of nutrients due to gluten intolerance

Celiac disease affects pediatric nutrition by causing an autoimmune reaction to gluten, which damages the villi in the small intestine. These villi are vital for nutrient absorption, and their damage leads to malabsorption of essential vitamins, minerals, and macronutrients. This malabsorption can significantly hinder a child's growth, development, and overall health.

In a child with nephrotic syndrome during an acute relapse, which dietary modification is most important?

Answer: Sodium restriction to manage edema

Sodium restriction reduces fluid retention and edema during nephrotic syndrome relapses; excess protein intake does not compensate for urinary losses and may worsen renal burden.

What is the primary purpose of evidence-based practice & research methods in the context of Certified Specialist in Pediatric Nutrition?

Answer: To ensure consistent quality and professional accountability

Evidence-Based Practice & Research Methods in Certified Specialist in Pediatric Nutrition primarily ensures consistent quality and professional accountability, forming the foundation of competent practice in this field.
