RUTF in SAM management — DTM&H MCQ

Correct answer: E — Can be administered at home without trained staff or clean water

The correct answer is E, can be administered at home without trained staff or clean water. RUTF is a ready-to-eat, low-moisture lipid-based paste that requires no dilution, cooking or mixing, unlike F-100 which is a milk-based liquid feed that must be reconstituted with clean water under supervised, hygienic conditions in a facility. This property underpins the shift from inpatient therapeutic feeding centres to community-based management of acute malnutrition (CMAM), allowing caregivers to treat uncomplicated severe acute malnutrition at home with periodic outpatient review rather than admission. In a famine setting such as South Sudan, where clean water, electricity and trained staff are scarce and facility access is limited, this portability and safety profile is what makes RUTF the practical tool for scaling up coverage, not any superiority in nutrient content per se. Why the other options are wrong: A, higher caloric density: RUTF and F-100 have a very similar energy density (around 5.3 to 5.5 kcal/g), so this is not the discriminating advantage; the key difference is preparation and safety, not calories per gram. B, eliminates need for micronutrient supplements: both formulations are already fortified with the same vitamin and mineral premix to WHO specification, so neither eliminates a supplement requirement that the other retains. C, contains antibiotics: neither RUTF nor F-100 contains antibiotics; antibiotics are given separately as part of SAM management protocols when indicated, independent of the feed chosen. E, provides passive immunity: RUTF is a peanut and milk powder based paste with added fats, sugar, vitamins and minerals; it contains no immunoglobulins or colostrum-derived components and confers no passive immunity. Key point: RUTF's decisive advantage is that its low water activity and ready-to-eat form allow safe, unsupervised home use without clean water or mixing, enabling community-based rather than facility-based treatment of uncomplicated SAM.
