Choose the most appropriate answer.
7. Which of these indicators or clinical signs could you use to identify children with SAM?
a) Bilateral pitting oedema
b) Visible severe wasting
c) MUAC <115mm
d) Weight-for-age <-3SD
e) Weight-for-height <-3SD
Feedback 
The correct answers are a), b), c) and e) although visible severe wasting should be used only if no other option is available. Severe acute malnutrition (SAM) is defined as severe wasting and/or oedema. Weight-for-age <-3 represents severe underweight, and may be due to stunting and/or wasting.
