Final answer:
If a child does not respond to voice, the next step is to assess the child's response to pain, as it can indicate the child's level of consciousness or neurological function.
Step-by-step explanation:
If the child does not respond to voice, you should assess the child's response to pain. This is known as nociception, which responds to injured stimuli. Neonates and children can hear and feel touch, and their eyes can detect light; however, the assessment of consciousness or responsiveness often involves checking for a response to a painful stimulus when the person is unresponsive to voice. It's crucial to differentiate between various sensory inputs such as pain, heat, cold, and others when assessing a child's neurological function.
