What are s/s of adrenal crisis?
The patient experiences generalized malaise and muscle weakness, muscle pain,
orthostatic hypotension, and vulnerability to cardiac dysrhythmias. Insufficiency of the
glucocorticoids affects blood glucose levels and causes symptoms of hypoglycemia.
There is also decreased secretion of gastrointestinal enzymes, which results in
anorexia, nausea and vomiting, flatulence, and diarrhea. These symptoms, as well as
anxiety, depression, and loss of mental acuity, have been correlated with the absence
of the peaks of cortisol output that normally occur every 24 hours.

Continued bleeding from an injection or IV site, extensive bruising in areas of injury,
ecchymoses where there has been no trauma, and petechiae.
