Addisons: decreased sodium means aldosterone levels do what?
decreased aldosterone
Addisons: decreased glucose levels means cortisol levels do what?
decreased cortisol
what does ACTH stimulation test test for?
adrenal corticoid insufficiency
ACTH helps to diagnose what?
primary and secondary adrenal insufficiency (Addisons)
what does ACTH test assess?
how well a patients adrenal hands respond to adrenocorticotropic hormone
explain the ACTH test
a shot of synthetic ACTH is injected into the muscle and then multiple blood draws at different intervals, typically 30 and 60 minutes
how do you treat Addisons disease?
ADD hormone
who is at risk for addisonian crisis
people who don’t respond to hormone therapy
those under extreme stress (MV accident, surgery, undergo trauma, abruptly stopping hormone therapy)
list manifestations of Addisonian Crisis
hypotension
cyanosis
fever
N&V
profound fatigue
renal shutdown
signs of shock
how do you treat addisonian crisis?
immediate treatment, IV fluids, glucose, electrolytes (esp. Na+), replacement of missing steroid hormones, and vasopressors

thin extremities
moon face
osteoporosis
amenorrhea
hirsutism
gynecomastia
personality changes
high infection risk
dexamethasone suppression test is used to diagnose what?
Cushings Disease
when is a dexamethasone suppression test done?
when HCP suspects the body is producing too much cortisol
what does a dexamethasone test measure?
suppression of ACTH
explain dexamethasone suppression test
dexamethasone suppression test is given at 11 pm and blood is drawn at 8 am; cortisol level should decrease after the patient receives dexamethasone
