Final answer:
On the Glasgow Coma Scale, a patient making incomprehensible sounds would be given a verbal response score of '2'. This scale assesses the level of consciousness in patients with head injuries.
Step-by-step explanation:
The Glasgow Coma Scale (GCS) is a neurological scale designed to assess a patient's level of consciousness after a head injury. The scale evaluates three aspects of a patient's responsiveness: eye-opening, verbal response, and motor response. The part of the assessment for verbal response includes several levels, where a score of '1' indicates no verbal response; '2' indicates incomprehensible sounds; '3' is for inappropriate words; '4' is for confused conversation; and '5' is for oriented conversation. Therefore, if a patient makes incomprehensible sounds, the nurse would determine their Glasgow Coma Scale score for verbal response as '2'.
