While in the emergency department, a client with C8 quadriplegia develops a blood pressure of 80/44 mmHg, pulse of 48 beats per minute, and respiratory rate of 18 breaths per minute. Which condition should the nurse suspect?

Rationale: A. This is incorrect because it usually occurs in clients with spinal cord injuries at T6 or above and is triggered by noxious stimuli such as bladder distention or constipation. Its hallmark is sudden, severe hypertension, pounding headache, flushed skin above the lesion, and bradycardia. Since the client in this scenario has hypotension, autonomic dysreflexia is unlikely. B. This is incorrect because it results from significant blood loss, leading to decreased circulating volume. The body typically compensates with tachycardia and vasoconstriction. The client’s bradycardia is inconsistent with the typical compensatory response to hemorrhagic shock. C. This is incorrect because it usually presents with sudden shortness of breath, chest pain, tachycardia, hypotension, and hypoxia. While hypotension may occur, bradycardia is uncommon. The client’s low blood pressure with bradycardia and normal respiratory rate points toward a different cause. D. Neurogenic shock is a type of distributive shock that occurs after a spinal cord injury above T6, including C8, due to loss of sympathetic nervous system control. This causes vasodilation, leading to hypotension, and unopposed parasympathetic activity, causing bradycardia. The client may also have warm, dry skin and relative hypothermia due to impaired thermoregulation, while the respiratory rate may remain normal if the diaphragm is unaffected.
