A school nurse is using Weber's test to check a child's hearing acuity. Which of the following actions should the nurse take?

Hold a vibrating tuning fork 1 to 2 cm (0.4 to 0.8 in) from the child's ears.

Place a vibrating tuning fork on the top of the child's head.

Whisper a statement to the child from 0.6 m (2 feet) away.

Apply a pair of headphones securely over the child's ears

Answer and Explanation

The Correct Answer is B

A. Hold a vibrating tuning fork 1 to 2 cm (0.4 to 0.8 in) from the child's ears – This describes the Rinne test, not the Weber test.

B. Place a vibrating tuning fork on the top of the child's head – Correct. The Weber test assesses hearing loss by placing a tuning fork on the midline of the skull to determine if sound is heard equally in both ears.

C. Whisper a statement to the child from 0.6 m (2 feet) away – This describes the whisper test, not the Weber test.

D. Apply a pair of headphones securely over the child's ears – Not part of the Weber test; this is used for audiometry testing.
