On assessment, she weighs 10 kg (below the 3rd percentile for age) and has a mid-upper arm circumference (MUAC) of 12 cm. She appears lethargic with sparse hair, bilateral ankle oedema, and hepatomegaly. Her mother reports she has been eating poorly for the past 6 months. Blood investigations show serum albumin 2.1 g/dL and haemoglobin 8.2 g/dL. The Anganwadi worker suspects severe protein-energy malnutrition (PEM).
