A client who had a C5 spinal cord injury (SCI) 2 years ago is admitted to the emergency department (ED) with a diagnosis of autonomic dysreflexia secondary to a full bladder. Which assessment finding should the nurse expect this client to exhibit?
Profuse diaphoresis and severe, pounding headache.
Pain and a burning sensation upon urination and hematuria.
Reports of chest pain and shortness of breath.
Hypotension and venous pooling in the extremities.
The Correct Answer is A
Choice A reason: Autonomic dysreflexia is a life-threatening condition triggered by noxious stimuli below the level of spinal cord injury, such as bladder distention. It leads to sudden hypertension, profuse sweating, and a severe headache due to unregulated sympathetic discharge.
Choice B reason: Pain and burning during urination may indicate a urinary tract infection but are not hallmark signs of autonomic dysreflexia.
Choice C reason: Chest pain and dyspnea are not typical features of autonomic dysreflexia and may suggest cardiac or pulmonary pathology instead.
Choice D reason: Hypotension and venous pooling are more consistent with neurogenic shock, not autonomic dysreflexia, which is characterized by hypertension and vasoconstriction.

Correct Answer is A
Explanation
Choice A reason: A serum sodium level of 185 mEq/L is critically high and indicates severe hypernatremia, which can lead to neurological impairment, seizures, and death. Immediate intervention is required to correct fluid balance and prevent complications.
Choice B reason: Dry skin and poor turgor suggest dehydration, which is concerning but not as immediately life-threatening as severe hypernatremia.
Choice C reason: Tachycardia may reflect dehydration or stress but is not as urgent as the dangerously elevated sodium level.
Choice D reason: Polyuria and thirst are hallmark symptoms of DI but are expected findings. They do not require emergency intervention unless accompanied by critical lab values.
Correct Answer is ["3"]
Explanation
To calculate the volume needed, use the ratio:
1,200,000 units / 2 mL = 600,000 units per mL.
To deliver 1,800,000 units:
1,800,000 ÷ 600,000 = 3 mL.
