## 문제

Situation: During the twice-yearly Garantisadong Pambata week, a nurse at a Barangay Health Station (BHS) screens children under 5 years of age and counsels their mothers on nutrition.

A 20-month-old girl has these findings:
Mid-upper arm circumference (MUAC): 114 mm
Weight-for-length: −2.6 z
Edema of both feet: none
Appetite test: passed
She has no general danger signs and no medical complication. Which action should the nurse take?

## 보기

1. Give home care advice and review her at the next weighing
2. Enroll her in supplementary feeding with counseling
3. Start ready-to-use therapeutic food with an antibiotic **✔ 정답**
4. Refer her urgently for inpatient therapeutic care

**정답: 3**

## 해설

Two rules apply. First, any one severe criterion (MUAC below 115 mm, weight-for-length below −3 z, or edema of both feet) classifies severe acute malnutrition, so her MUAC of 114 mm makes her severe even though her weight-for-length alone falls in the moderate range. Second, with no complication, no danger sign, and a passed appetite test, it is uncomplicated severe acute malnutrition, managed as an outpatient with ready-to-use therapeutic food and an oral antibiotic.

Clinical reasoning pathway

The first step is to classify the severity of malnutrition. This child has a MUAC of 114 mm, which falls below the 115 mm threshold used in community-based screening. Even though the weight-for-length of −2.6 z is in the moderate range, any one severe criterion is enough to classify severe acute malnutrition (SAM). The three independent diagnostic criteria for SAM are bilateral pitting edema, MUAC below the cutoff, and weight-for-height below −3 z; they do not need to occur together [1][2]. Because the MUAC criterion is met, this child has SAM despite the less severe weight-for-length value.

The second step is to determine whether the SAM is complicated or uncomplicated. The child has no general danger signs, no medical complication, no edema of both feet, and passed the appetite test. These findings point to uncomplicated severe acute malnutrition, which is the form suitable for outpatient management rather than inpatient care [1][3]. In outpatient therapeutic programs, the standard treatment package includes ready-to-use therapeutic food (RUTF) plus a short course of an oral antibiotic, because children with SAM often have subclinical infections even when they appear clinically stable [2].

| Finding | Value | Interpretation |
| --- | --- | --- |
| MUAC | 114 mm | Below 115 mm cutoff; meets SAM criterion |
| Weight-for-length | −2.6 z | Moderate range alone, but does not override the MUAC finding |
| Edema of both feet | None | No edema criterion; does not change SAM classification because MUAC is already positive |
| Appetite test | Passed | Supports outpatient rather than inpatient management |
| Danger signs or complications | None | Rules out complicated SAM requiring urgent referral |

Key point! The appetite test is the main clinical gatekeeper for deciding between outpatient and inpatient care. A child with SAM who passes the appetite test and has no medical complications can be treated in the community with RUTF and routine oral antibiotics. If the appetite test were failed, or if any danger sign or complication were present, urgent referral for inpatient therapeutic care would be required [2][3].

Watch out! Do not be misled by the weight-for-length of −2.6 z. In isolation that value suggests moderate acute malnutrition, but classification is based on the most severe criterion present. The MUAC of 114 mm is the decisive finding here, and it upgrades the classification to SAM [1][2].

The rationale for adding an antibiotic in uncomplicated SAM is that these children have impaired immune function and a high burden of occult infection. Even without overt signs of infection, routine antibiotic use reduces mortality and improves nutritional recovery during outpatient therapeutic feeding [2]. Supplementary feeding alone is insufficient for SAM because the energy density and micronutrient composition of RUTF are specifically designed to support rapid catch-up growth and metabolic stabilization in severely malnourished children [2][3].References (research sources)

Uncomplicated SAM Outpatient CareMUAC below 115 mm is enough to start therapeutic feeding
Classify severe acute malnutrition when any one criterion is met: MUAC

## 핵심 개념

- **Severe acute malnutrition (SAM)** — Defined by any one of MUAC
- **Ready-to-use therapeutic food (RUTF)** — Energy-dense therapeutic food for outpatient management of uncomplicated SAM
- **Appetite test** — Assessment of a child's ability to eat RUTF; passing supports outpatient rather than inpatient care
- **Mid-upper arm circumference (MUAC)** — Screening measure for malnutrition;
