Clinical analysis: A 16-month-old child weighing 8 kg is being assessed on a growth chart.
The WHO child growth standards classify nutritional status based on weight-for-age, weight-for-height, and MUAC. For a 16-month-old, the expected weight is approximately 10-11 kg. At 8 kg, this child is significantly underweight.
Management based on severity:- Between median and -2 SD: Normal -- reassure mother
- Between -2 SD and -3 SD: Moderate acute malnutrition -- community-based management, dietary counseling
- Below -3 SD or MUAC $<$ 115 mm: Severe acute malnutrition (SAM) -- refer to Nutrition Rehabilitation Center (NRC)
The answer key designates this child as having SAM requiring NRC referral. NRC provides therapeutic feeding, management of medical complications, and follow-up.
