Final answer:
To address autonomic dysreflexia in a client with a C-7 spinal cord injury, the nurse should first look for an acutely distended bladder, as it's a common trigger.
Step-by-step explanation:
In the case of a client with a C-7 spinal cord injury who is experiencing autonomic dysreflexia, the nurse should first assess for an acutely distended bladder. Autonomic dysreflexia is a condition where there is an overreaction of the autonomic nervous system to stimulation, which can be life-threatening if not addressed promptly. An overfull bladder is a common precipitating factor for this reflex in individuals with spinal cord injuries, as the normal sensations and control that notify a person when to empty the bladder are disrupted. It is crucial to identify and alleviate the cause to prevent complications, including severe hypertension.
