Pediatric Nutrition Practice Questions

Q: Which of the following is NOT a symptom of Kwashiorkor?

Hypertension. ***Hypertension*** - **Hypertension** is generally **NOT a direct symptom** of Kwashiorkor; rather, children with Kwashiorkor often have **low blood pressure** due to overall cardiovascular system depression. - While chronic malnutrition can have various systemic effects, elevated blood pressure is not a characteristic clinical feature of this condition. - This is the correct answer as the question asks what is NOT a symptom. *Hair changes and depigmentation* - This is a **classic symptom** of Kwashiorkor, characterized by sparse, brittle hair that may be discolored (e.g., reddish or yellowish - "flag sign"). - These changes reflect the severe protein deficiency interfering with hair follicle function and melanin production. *Edema* - **Edema**, particularly in the lower extremities and face, is a **hallmark symptom** of Kwashiorkor, caused by severe protein deficiency leading to decreased oncotic pressure. - This results in fluid shifting from the intravascular space into the interstitial space. *Growth retardation* - **Growth retardation** (stunting) is a common and severe symptom of Kwashiorkor, reflecting the long-term impact of inadequate protein and energy intake on physical development. - Both height and weight are significantly below age-appropriate norms.

Q: Which of the following statements about the differences between human milk and cow milk is NOT true?

Cow milk has comparatively more fat than human milk.. ***Cow milk has comparatively more fat than human milk.*** - This statement is **incorrect** and is the answer to this "NOT true" question. Human milk generally has a **higher fat content** (3.5-4.5 g/100mL) than cow milk (~3.5 g/100mL), which is crucial for the rapid neurological development of infants. - The fat in human milk is also more **bioavailable** due to the presence of lipases, aiding digestion and absorption. - Human milk contains essential **long-chain polyunsaturated fatty acids (LCPUFAs)** like DHA and ARA that support brain and retinal development. *Cow milk has comparatively more protein than human milk.* - This statement is **true**. Cow milk contains significantly **more protein** (~3.3 g/100mL) compared to human milk (~1.0 g/100mL), particularly **casein protein**. - While more protein might seem beneficial, the higher protein load in cow milk is harder for an **infant's immature kidneys** to process and increases renal solute load. *Cow milk has comparatively more calcium than human milk.* - This statement is **true**. Cow milk contains approximately **120 mg/100mL calcium** compared to human milk which has about **30 mg/100mL**. - However, the **bioavailability** of calcium and the optimal calcium-to-phosphorus ratio in human milk favor better absorption despite the lower absolute amount. *Cow milk has comparatively more casein than human milk.* - This statement is **true**. Cow milk has a **casein-to-whey ratio of 80:20**, while human milk has a ratio of approximately **40:60** (more whey). - The predominance of whey proteins in human milk makes it easier to digest, forming softer curds in the infant's stomach.

Q: In a child having diarrhoea with perianal moist crust, which condition is most likely diagnosed?

Acrodermatitis enteropathica. ***Acrodermatitis enteropathica*** - This condition is a **zinc deficiency** syndrome, which can be either inherited or acquired. - It presents with a classic triad of **diarrhoea**, **dermatitis** (often periorificial and acral with moist, crusted lesions), and **alopecia**. - The **perianal moist crust** is a characteristic finding of the periorificial dermatitis seen in this condition. *Pellagra* - Pellagra is caused by **niacin (Vitamin B3) deficiency** and is characterized by the "4 D's": **dermatitis** (often sun-exposed areas), **diarrhoea**, **dementia**, and eventually death. - The dermatitis of pellagra is typically **symmetrical, hyperpigmented, and photosensitive**, not moist perianal crusts, differentiating it from the presented case. *Riboflavin deficiency* - **Riboflavin deficiency** typically manifests as **cheilosis**, angular stomatitis, glossitis, and seborrheic dermatitis, but not specifically perianal moist crusts with diarrhoea. - While it can affect mucous membranes, the specific perianal presentation with diarrhoea points away from this diagnosis. *Kwashiorkor* - **Kwashiorkor** is a form of protein-energy malnutrition that can present with **diarrhoea** and skin changes (flaky paint dermatosis, hypopigmentation). - However, the skin changes are typically **desquamating** and affect dependent areas, not the characteristic **moist, crusted periorificial lesions** seen in zinc deficiency. - Kwashiorkor also typically presents with **edema**, which is not mentioned in this case.

Q: What is the minimum weight gain recommended for a malnourished child during the catch-up growth phase of nutritional rehabilitation?

5 gm/kg/day. ***Correct: 5 gm/kg/day*** - According to **WHO guidelines** for management of severe acute malnutrition and **IAP recommendations**, the **minimum acceptable weight gain** during the catch-up growth phase is **5 gm/kg/day**. - This represents the **threshold for adequate nutritional rehabilitation** - gains below this indicate inadequate recovery and require reassessment of the feeding protocol. - Weight gain of 5 gm/kg/day or more indicates that the child is responding to treatment. *Incorrect: 10 gm/kg/day* - A weight gain of **10 gm/kg/day** represents **good/satisfactory catch-up growth**, not the minimum requirement. - This is considered an **optimal target** rather than the minimum acceptable threshold. - While desirable, the question specifically asks for the minimum recommendation, which is 5 gm/kg/day. *Incorrect: 15 gm/kg/day* - A weight gain of **15 gm/kg/day** reflects **excellent catch-up growth** and is at the higher end of optimal targets. - This exceeds both the minimum requirement and the good target. - While indicating very successful rehabilitation, it is not the minimum recommendation. *Incorrect: 20 gm/kg/day* - A weight gain of **20 gm/kg/day** is an **exceptionally high rate** rarely achieved in clinical practice. - While theoretically possible with intensive feeding protocols, this far exceeds the minimum requirement. - Such high rates may require monitoring for refeeding syndrome and metabolic complications.

Q: When should breastfeeding be initiated after a normal delivery?

Immediately after delivery. **Correct: Immediately after delivery** - Initiating breastfeeding **within the first hour** of birth (early initiation) is crucial for establishing **successful lactation** and promoting optimal infant health. - This early initiation allows for **skin-to-skin contact**, which helps stabilize the newborn's temperature, heart rate, and breathing, and facilitates **bonding** between mother and baby. - Aligned with **WHO and UNICEF recommendations** for best practice in postpartum care. *Incorrect: 2 hours after delivery* - While earlier is generally better, waiting two hours misses the **optimal window** for initiating feeding and bonding. - The newborn's **alert period** is typically strongest in the first hour post-birth, making it an ideal time for the first latch. *Incorrect: 4 hours after delivery* - Delaying breastfeeding by four hours can make it more challenging for the baby to latch effectively as they may have passed their **initial alert state** and become sleepy. - This delay can also hinder the establishment of the mother's **milk supply**, as stimulation from early feeding is important for prolactin release. *Incorrect: 6 hours after delivery* - Waiting six hours significantly **misses the critical window** for early initiation and can lead to increased difficulties with breastfeeding. - Prolonged delays may necessitate supplementation, potentially interfering with exclusive breastfeeding and establishing a **strong milk supply**.

Q: What is the amount of protein (in grams) in human milk per 100 milliliters?

1.1. ***1.1*** - Human milk contains approximately **1.1 grams of protein per 100 milliliters**, which is appropriate for the growth and development of infants. - The protein composition of human milk is lower than that of cow's milk, but it is highly bioavailable and easily digestible due to the presence of **whey protein** and **casein**. *2.2* - This value is significantly higher than the typical protein content found in human milk. Such a high concentration could potentially strain an infant's immature kidneys. - The **protein content of cow's milk** (around 3.3-3.5 g/100ml) is much higher than human milk and is not suitable for routine infant feeding without modification. *3.3* - This protein concentration is also substantially higher than what is naturally found in human milk, possibly exceeding an infant's metabolic needs and kidney function. - This value is closer to the protein content of **unmodified cow's milk**, which is why it is often diluted or altered for infant formula. *4.4* - This protein amount is exceptionally high and not representative of natural human milk. - Excessive protein intake in infants could increase the risk of **obesity later in life** and place an undue burden on the **renal system**.

Q: A 2-year-old child with a weight of 6.4 kg and vitamin A deficiency has what grade of malnutrition based on the expected weight of 12 kg?

Third degree. ***Third degree*** - The child's current weight (6.4 kg) is 53.3% of the expected weight (12 kg), calculated as (6.4 / 12) * 100%. - A weight-for-age percentage **below 60%** of expected weight indicates **third-degree malnutrition** (severe malnutrition) using the Gómez classification. - The child's weight at 53.3% clearly falls into this severe malnutrition category. *First degree* - This degree of malnutrition is classified when the child's weight-for-age is between **75% and 90%** of the expected weight (mild malnutrition). - The given child's weight of 53.3% is much lower than this range. *Second degree* - This degree of malnutrition is indicated when the child's weight-for-age is between **60% and 75%** of the expected weight (moderate malnutrition). - The child's weight at 53.3% falls below this threshold. *Fourth degree* - The Gómez classification typically defines three degrees of malnutrition based on percentage of expected weight. - While other classifications exist, "fourth degree" is not standard in the Gómez classification system; such severe cases are generally grouped under **third-degree** or classified as **severe malnutrition**.

Q: Osmolarity of ReSoMal is

311. **Correct: 311** - The **osmolarity of ReSoMal is 311 mOsm/L**, making it slightly hypertonic but suitable for rehydration in severe malnutrition to minimize fluid shifts. - This specific osmolarity is designed to provide adequate electrolytes and glucose while avoiding the risks of hypotonic or overly hypertonic solutions in malnourished patients. *Incorrect: 200* - An osmolarity of 200 mOsm/L would be considered **hypotonic**, which could lead to shifts of fluid into cells and potentially cause cerebral edema, especially in malnourished individuals. - Such a low osmolarity is not appropriate for rehydration in patients with severe acute malnutrition (SAM) due to the risk of intracellular overhydration. *Incorrect: 300* - While 300 mOsm/L is close to physiological osmolarity, **ReSoMal is specifically formulated with 311 mOsm/L** to optimize rehydration for severely malnourished children. - Solutions around 300 mOsm/L are generally isotonic but lack the precise electrolyte and glucose balance needed for the complex physiological state of severe malnutrition. *Incorrect: 350* - An osmolarity of 350 mOsm/L would be **hypertonic**, meaning it has a higher solute concentration than body fluids. - This could draw water out of cells, leading to dehydration of intracellular compartments and potentially causing hypernatremia or osmotic diuresis, which is not suitable for rehydrating malnourished patients.

Q: Colostrum contains all of the following in excess of milk, except:

Fat. ***Fat*** - Colostrum has a **lower fat content** compared to mature milk. - While it provides concentrated nutrients in small volumes, its primary immunological role does not rely on high lipid levels, which increase as milk matures. *Protein* - Colostrum is significantly **richer in protein** than mature milk, especially **casein** and **whey proteins**. - These proteins contribute to its nutritional and immunological benefits. *Minerals* - Colostrum contains higher concentrations of several minerals, including **sodium**, **potassium**, **chloride**, and **zinc**, compared to mature milk. - These minerals are crucial for the newborn's initial growth and development. *Immunoglobulins* - Colostrum is often called "liquid gold" due to its extremely high concentration of **immunoglobulins**, particularly **IgA**. - These antibodies provide crucial **passive immunity** to the newborn, protecting against infections.

Q: A 6-month-old infant is exclusively fed on goat's milk. What condition is he most likely to develop?

Megaloblastic anemia due to folate deficiency. ***Megaloblastic anemia due to folate deficiency*** - Goat's milk is **severely deficient in folate (vitamin B9)**, containing <1 μg/100mL compared to the infant requirement of ~50 μg/day - Exclusive goat's milk feeding in infants classically leads to **megaloblastic anemia** due to this folate deficiency, historically known as "goat's milk anemia" - Folate is essential for DNA synthesis and red blood cell maturation; deficiency causes macrocytic anemia with hypersegmented neutrophils - This typically manifests at **4-6 months of age** when maternal folate stores are depleted *Iron deficiency anemia* - While both cow's milk and goat's milk are low in iron, iron deficiency typically develops later (after 6-9 months) - Iron deficiency causes **microcytic** anemia, not the **macrocytic** anemia seen with folate deficiency - Though a concern with goat's milk feeding, **folate deficiency** is the more immediate and specific consequence *Anemia of chronic disease* - This results from underlying chronic inflammatory or infectious conditions affecting iron utilization and erythropoiesis - Nothing in this infant's dietary history suggests chronic inflammation or infection - Not related to nutritional deficiency from goat's milk *Sideroblastic anemia* - Characterized by impaired heme synthesis with ring sideroblasts in bone marrow - Causes include genetic defects, myelodysplastic syndromes, or toxin exposure (lead, alcohol) - Not caused by dietary deficiencies from goat's milk feeding
