After checking vital signs in a client with autonomic dysreflexia, what is the next action a nurse should take?

The next action after checking vital signs in a client with autonomic dysreflexia is to place the client in a high-Fowler's position. This position helps to decrease blood pressure by facilitating venous return and promoting easier respiratory function, which is crucial in managing any hypertensive crisis associated with autonomic dysreflexia.

In this condition, an overactive autonomic nervous system leads to severe hypertension, typically in response to a noxious stimulus below the level of injury, such as a full bladder or bowel impaction. By elevating the client's head above the heart, the risk of stroke or other vascular complications can be mitigated while further interventions, such as identifying and treating the underlying cause, are initiated.

While managing blood pressure and monitoring for infection are critical components of care, positioning the client effectively addresses the immediate risk of high blood pressure resulting from this syndrome. The high-Fowler's position is a priority intervention that directly impacts the client's safety and stability.
