Final answer:
The correct manifestation indicating autonomic dysreflexia (AD) in a client with a cervical spinal cord injury is hypertension.
Step-by-step explanation:
The correct answer is b) Hypertension.
Autonomic dysreflexia (AD) is a potentially life-threatening condition that can occur in individuals with spinal cord injury. It is characterized by a sudden and dangerous elevation in blood pressure. AD typically occurs as a result of a noxious stimulus below the level of the injury, such as a bladder distention or constipation. In response to the stimulus, the sympathetic nervous system becomes hyperactive, causing vasoconstriction and increased heart rate, resulting in hypertension.
