The nurse is caring for a patient who has had a spinal cord injury at level C5-C6 as a result of an automobile accident. The patient suddenly develops severe hypertension, throbbing headache, blurred vision, and bradycardia.
What is the priority nursing intervention?
This is wrong because administering antihypertensive medication as prescribed may not be effective or appropriate for autonomic dysreflexia.
The hypertension is caused by a reflex mechanism and not by a primary cardiovascular disorder. Moreover, antihypertensive drugs may cause hypotension once the stimulus is removed.
This is wrong because elevating the head of bed to 90 degrees may not be enough to lower the blood pressure. It may also increase the risk of orthostatic hypotension once the stimulus is removed. However, sitting the patient upright and loosening any tight clothing are recommended as initial steps to reduce the blood pressure.
Autonomic dysreflexia is a disorder of autonomic nervous system dysregulation that occurs in patients with a spinal cord injury above T6.
It is caused by an exaggerated reflex response of the sympathetic nervous system due to an irritating stimulus below the spinal cord injury. It leads to severe hypertension and is a medical emergency.
Bladder or bowel distension are the most common triggers of autonomic dysreflexia.
Therefore, the priority nursing intervention is to check for bladder distention or fecal impaction and relieve them as soon as possible.
This can help to eliminate the stimulus and lower the blood pressure.
This is wrong because applying a cooling blanket to lower body temperature is not indicated for autonomic dysreflexia. There is no evidence that body temperature is elevated or contributes to the hypertension in this condition. A cooling blanket may also cause vasoconstriction and worsen the hypertension.
The correct answer is C.
Check for bladder distention or fecal impaction.

Choice A is wrong because administering antihypertensive medication as prescribed may not be effective or appropriate for autonomic dysreflexia.
The hypertension is caused by a reflex mechanism and not by a primary cardiovascular disorder. Moreover, antihypertensive drugs may cause hypotension once the stimulus is removed.
Choice B is wrong because elevating the head of bed to 90 degrees may not be enough to lower the blood pressure. It may also increase the risk of orthostatic hypotension once the stimulus is removed. However, sitting the patient upright and loosening any tight clothing are recommended as initial steps to reduce the blood pressure.
Choice D is wrong because applying a cooling blanket to lower body temperature is not indicated for autonomic dysreflexia. There is no evidence that body temperature is elevated or contributes to the hypertension in this condition. A cooling blanket may also cause vasoconstriction and worsen the hypertension.
Normal ranges for blood pressure vary depending on age, sex, and other factors.
However, a general guideline is that systolic blood pressure should be less than 120 mm Hg and diastolic blood pressure should be less than 80 mm Hg for most adults.
Normal ranges for heart rate also vary depending on age, activity level, and other factors.
However, a general guideline is that resting heart rate should be between 60 and 100 beats per minute for most adults.
