Arm Circumference (MUAC) VR Nursing Simulation
Mid-upper-arm circumference is a core malnutrition screen. The learner marks the midpoint between acromion and olecranon, lets the arm hang loose and measures the circumference.

Learning objectives
By the end of this experience the learner can:
- Locate the anatomical landmarks for arm circumference (muac): at the midpoint of the upper arm, arm hanging relaxed, tape snug but not compressing.
- Use the non-stretch measuring tape correctly and read it to the required precision.
- Position the patient correctly and repeat the measurement to confirm consistency.
- Record the value with the side measured and compare it with reference ranges.

Procedure steps
- Explain the measurement to the virtual patient and position them as required.
- Palpate and mark the landmarks (at the midpoint of the upper arm, arm hanging relaxed, tape snug but not compressing).
- Apply the non-stretch measuring tape as demonstrated and take the reading.
- Repeat the measurement; if the two readings differ beyond the tolerance, take a third.
- Record the mean value and the instrument used.
Assessment
Landmark accuracy, instrument placement and the difference between the learner's reading and the reference value are checked automatically, with a tolerance set by the instructor.
Equipment and setting
Instrument: non-stretch measuring tape. Landmarks: at the midpoint of the upper arm, arm hanging relaxed, tape snug but not compressing.

Arm Circumference (MUAC) FAQ
What educators ask about this scenario.
What will I practise in the Arm Circumference (MUAC) scenario?
Mid-upper-arm circumference is a core malnutrition screen. The learner marks the midpoint between acromion and olecranon, lets the arm hang loose and measures the circumference.
How is performance assessed?
Landmark accuracy, instrument placement and the difference between the learner's reading and the reference value are checked automatically, with a tolerance set by the instructor.
