What is this device used by health workers to assess nutritional status of under-5 children?
**Core Concept**
The device in question is used to assess the nutritional status of under-5 children, which is a critical aspect of pediatric care. It involves measuring the mid-upper arm circumference (MUAC) of children, which is a reliable indicator of acute malnutrition.
**Why the Correct Answer is Right**
The MUAC tape is used to measure the mid-upper arm circumference of children, typically between the humerus and olecranon. This measurement is used to assess the nutritional status of children, particularly in emergency settings or areas with high malnutrition rates. The World Health Organization (WHO) recommends using the MUAC tape to identify children at risk of acute malnutrition. A MUAC measurement of less than 11.5 cm indicates severe acute malnutrition.
**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect because the MUAC tape is not used to measure body temperature, which is typically measured using a thermometer.
* **Option B:** This option is incorrect because the MUAC tape is not used to measure blood pressure, which is typically measured using a sphygmomanometer.
* **Option C:** This option is incorrect because the MUAC tape is not used to measure weight, which is typically measured using a scale.
**Clinical Pearl / High-Yield Fact**
The MUAC tape is a simple, yet effective tool for assessing nutritional status in under-5 children. It is essential to use the correct tape and measurement technique to ensure accurate results.
**Correct Answer: C. MUAC Tape**
