Pediatric Nutrition Practice Questions

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

Q: A child of 8 kg has Bitot's spots in both eyes. Which of the following is the most appropriate schedule to prescribe vitamin A to this child?

2 lakh units orally on day 0, 1, 14. ***2 lakh units orally on day 0, 1, 14*** - For a child weighing **8 kg** with **Bitot's spots (WHO classification X1B)**, the therapeutic dose is **200,000 IU** (2 lakh units) of vitamin A. - The standard WHO/IAP schedule for treating **vitamin A deficiency with ocular signs** is administration on **Day 0, Day 1, and Day 14** to rapidly replete stores and prevent progression. - The **oral route** is preferred for **Bitot's spots without corneal ulceration**, as it is effective, safe, and well-tolerated. - **IM route** is reserved for severe xerophthalmia (X2/X3 with corneal ulceration), persistent vomiting, or inability to take oral medications. *2 lakh units orally on day 0, 14* - Although the individual dose of **200,000 IU** is correct for this 8 kg child with **Bitot's spots**, this schedule misses the critical **Day 1 dose**. - The missing dose on Day 1 delays rapid **vitamin A replenishment**, which is crucial for preventing progression of **ocular damage** and achieving adequate tissue stores. *1 lakh units orally on day 0, 14* - This dose of **100,000 IU** is inadequate for a child weighing **8 kg or more** with clinical **vitamin A deficiency**. - WHO guidelines recommend **100,000 IU for children <8 kg** and **200,000 IU for children ≥8 kg**, making this dosage insufficient. - Additionally, the schedule is incomplete as it misses the **Day 1 dose**. *1 lakh units orally on day 0, 1, 14* - While the schedule of Day 0, Day 1, and Day 14 is appropriate, the **dose of 100,000 IU is inadequate** for a child weighing **8 kg**. - This lower dose may not provide sufficient **vitamin A replenishment** to reverse **Bitot's spots** and prevent progression to more severe xerophthalmia.

Q: Which of the following is a sign of good attachment during breastfeeding?

Baby's chin touching the breast with mouth wide open. ***Baby's chin touching the breast with mouth wide open*** - This is a **key sign of good attachment** during breastfeeding, indicating proper positioning. - When the baby's **chin touches the breast** and the **mouth is wide open**, it ensures a **deep latch** with much of the areola in the mouth. - Other signs of good attachment include **cheeks rounded** (not dimpled), **lips flanged outward**, and **rhythmic sucking** with audible swallowing. - Good attachment ensures **effective milk transfer** and prevents **nipple trauma**. *Baby's lips are pursed or turned inward* - This indicates a **poor latch**, as the baby's lips should be flanged outward to create a good seal. - Pursed or tucked-in lips can cause **nipple pain** and **ineffective milk transfer**. *Clicking or smacking sounds during feeding* - These sounds are signs of a **poor vacuum seal** and **ineffective attachment**. - Good attachment produces **rhythmic sucking** with **audible swallowing**, not clicking sounds. *Dimpling of cheeks during sucking* - **Dimpled cheeks** indicate the baby is sucking on the cheeks rather than effectively drawing milk from the breast. - This is a sign of **poor attachment** and **inefficient milk transfer**; cheeks should appear **rounded** with good attachment.

Q: What is the Na+ content of ReSoMal (rehydration solution for malnourished children)?

45 mmol/L. ***45 mmol/L*** - ReSoMal is specifically formulated for **severely malnourished children** and contains a lower sodium concentration (45 mmol/L) than standard oral rehydration solutions (ORS). - This reduced sodium content helps to prevent **hypernatremia**, a common complication in severely malnourished children due to impaired renal function and reduced thirst sensation. *30 mmol/L* - This sodium concentration is **lower** than the recommended amount for ReSoMal. - Using a solution with such a low sodium content would be insufficient to replace **necessary electrolytes** and could lead to **hyponatremia** and other complications in malnourished children. *60 mmol/L* - This sodium concentration is **higher** than the recommended amount for ReSoMal. - A 60 mmol/L sodium concentration, while lower than standard ORS, would still carry an increased risk of **hypernatremia** in severely malnourished children, whose regulatory mechanisms are compromised. *90 mmol/L* - This is the sodium concentration found in **standard WHO ORS**, which is used for rehydration in children who are not severely malnourished. - For severely malnourished children, this concentration is too high and would significantly increase the risk of **hypernatremia** and cerebral edema due to their altered physiological state.

Q: A 3-year-old girl is brought for diarrhoea of 2 weeks' duration. She weighs 8 kg and her height is 93 cm. Her nutritional status can be described as what?

Severe malnutrition. ***Severe malnutrition*** - This 3-year-old child weighing 8 kg with height 93 cm has a **weight-for-height Z-score of approximately -3 to -4 SD**, indicating **severe acute malnutrition (SAM)**. - Normal weight for a 3-year-old is approximately 12-16 kg; 8 kg represents profound wasting with relatively preserved height (stunting less severe than wasting). - According to **WHO classification**, SAM is defined as weight-for-height < -3 SD, MUAC < 115 mm, or bilateral pitting edema. - The 2-week history of diarrhea contributes to acute nutritional deterioration, making this severe malnutrition. *Mild malnutrition* - Mild acute malnutrition would have weight-for-height between -1 to -2 SD. - This child's anthropometric deficit (8 kg at 3 years) is far too severe to be classified as mild. - Children with mild malnutrition typically maintain better growth parameters and clinical status. *Moderate malnutrition* - Moderate acute malnutrition (MAM) is defined as weight-for-height between -2 to -3 SD or MUAC 115-125 mm. - This child's weight of 8 kg for height 93 cm falls well below the -3 SD threshold. - The degree of wasting here exceeds the moderate malnutrition category. *Very severe malnutrition* - **"Very severe malnutrition" is not a standard WHO classification category** for pediatric malnutrition. - WHO uses a three-tier system: **mild, moderate, and severe** acute malnutrition, with severe being the most critical category. - Severe acute malnutrition encompasses what might colloquially be called "very severe" - including marasmus (severe wasting) and kwashiorkor (edematous malnutrition).

Q: A child with protein-energy malnutrition is brought to the outpatient department. Which of the following statements about Gomez's classification of malnutrition in children is true?

Weight is compared with standard weights for age.. ***Weight is compared with standard weights for age.*** - Gomez's classification is based primarily on **weight-for-age** as a percentage of a reference standard. - It categorizes malnutrition into **Grade I (75-90% of expected weight), Grade II (60-75%), and Grade III (<60%)** based on the severity of the weight deficit. - This is a **simple, early classification system** that uses only one anthropometric parameter. *Height-for-age is the primary parameter used.* - This is incorrect. Gomez's classification **does not use height** as a parameter. - Height-based classifications include **Waterlow's classification** (which uses height-for-age to assess stunting) and **WHO growth standards**. - The limitation of Gomez's system is its inability to differentiate **acute from chronic malnutrition** without height data. *It considers both height and weight for assessment.* - This is incorrect for Gomez's classification; this approach is characteristic of other classification systems like the **Waterlow classification** or the newer **WHO growth standards**, which use indices like weight-for-height and height-for-age. - Gomez's method uses a **single anthropometric measure** (weight-for-age) to classify malnutrition. *Weight is a primary parameter compared to age standards.* - While this statement correctly identifies weight as a primary parameter compared to age standards, **Option A is more precise and direct**. - Option A specifically states the comparison of "weight with standard weights for age," which clearly describes the methodology of Gomez's classification. - This option is less specific about what is being compared.

Q: What is the recommended oral dose of vitamin A to be given in a 10-month-old child on each of days 1, 2, and 28?

100,000 IU. ***100,000 IU*** - The recommended oral dose of Vitamin A for infants aged 6-11 months is **100,000 IU** on day 1, day 2, and day 28 for the treatment of severe vitamin A deficiency or in high-risk areas. - This dosage helps to rapidly replenish vitamin A stores and reduce the risk of associated complications like **xerophthalmia**. *50,000 IU* - This dose is lower than the recommended amount for treating vitamin A deficiency in infants aged 6-11 months. - A 50,000 IU dose is typically given to infants under 6 months of age. *200,000 IU* - This dose is recommended for children 12 months and older, or for pregnant women with severe deficiency who are not experiencing night blindness. - Administering 200,000 IU to a 10-month-old child could pose a risk of **hypervitaminosis A** due to their smaller body weight and developing metabolic systems. *600,000 IU* - This dose is excessively high and would lead to significant **vitamin A toxicity**, especially in an infant. - It is not a therapeutic dose recommended for any age group in the context of vitamin A supplementation programs.

Q: A child who is exclusively fed on cow's milk is likely to have a deficiency of which of the following?

Iron deficiency. ***Iron deficiency*** - Cow's milk is **poor in bioavailable iron** and high in calcium, which can inhibit iron absorption. - Excessive cow's milk intake by infants can lead to **gastrointestinal blood loss** (due to protein-induced enteropathy), further exacerbating iron deficiency. *Vitamin A deficiency* - Cow's milk contains a significant amount of **Vitamin A**, making deficiency unlikely from exclusive feeding. - While processing can reduce some vitamin content, it's not a primary cause of **Vitamin A deficiency** in this context. *Thiamine deficiency* - Cow's milk is a **good source of Thiamine (Vitamin B1)**, especially whole milk. - **Thiamine deficiency** is more commonly seen in populations with limited access to fortified grains or those with chronic alcoholism. *Riboflavin deficiency* - Cow's milk is an excellent source of **Riboflavin (Vitamin B2)**, making deficiency improbable with exclusive feeding. - **Riboflavin deficiency** typically manifests with angular cheilosis and glossitis, and is rare in children consuming dairy.

Q: Kwashiorkor is diagnosed in growth-retarded children along with:

Edema and mental changes. ***Edema and mental changes*** - **Kwashiorkor** is characterized primarily by **edema**, often pitting, due to **hypoalbuminemia** from severe protein deficiency. - **Mental changes**, including apathy, irritability, and decreased responsiveness, are also common features reflecting the brain's impaired function due to malnutrition. *Edema and hypopigmentation in skin* - While kwashiorkor does cause **edema**, **hypopigmentation of the skin** can occur but is not a universally defining or primary diagnostic feature as mental changes are. - Skin changes, often described as "flaky paint" dermatosis, are diverse and not limited to just hypopigmentation. *Hepatomegaly and mild anemia* - **Hepatomegaly** (enlarged liver) due to fatty infiltration is a common finding in kwashiorkor, and **anemia** is also frequently present. - However, these are secondary manifestations that do not define the core clinical picture as strongly as edema and mental status alterations. *Hypopigmentation and mild anemia* - While both **hypopigmentation** and **mild anemia** can be present in kwashiorkor, they are not the most prominent or diagnostic features. - The absence of **edema**, a hallmark symptom, makes this option less complete in describing the primary clinical presentation.

Q: At what age should the first dose of vitamin A be administered to children?

6 months. ***6 months*** - The **World Health Organization (WHO)** and **Indian Academy of Pediatrics (IAP)** recommend the first dose of vitamin A supplementation at **6 months of age** as per updated guidelines. - The first dose is **100,000 IU (1 lakh IU)**, given when complementary feeding begins, followed by subsequent doses every 6 months until 5 years of age. - This timing ensures protection during the **critical period** when maternal vitamin A stores deplete and dietary intake may be insufficient, reducing the risk of **xerophthalmia, impaired immunity, and childhood mortality**. *3 months* - Administering vitamin A at 3 months is **too early** as infants typically have adequate vitamin A stores from maternal sources and exclusive breastfeeding. - Early high-dose supplementation at this age is **not recommended** and could potentially lead to toxicity. *9 months* - While **older guidelines** (National Vitamin A Supplementation Programme) recommended the first dose at 9 months with routine immunization, **current IAP and WHO recommendations** have shifted this to **6 months** for earlier protection. - 9 months is now considered the timing for the **second dose** (200,000 IU) in the updated schedule. *12 months* - Delaying the first dose until 12 months means missing the **critical window** between 6-12 months when vitamin A deficiency risk rises significantly. - This delay increases the risk of **vitamin A deficiency-related morbidities** including impaired immunity, increased susceptibility to infections, and ocular complications like night blindness.
