Adrenal Dysfunction Flashcards
What is Cushing’s disease?
Hypersecretion of the adrenal cortex of one or all hormones (cortisol and androgens)
What causes Cushing’s disease?
Cortisol secreting tumor (most are benign)
Or adrenal hyperplasia r/t oversecretion of SCTH (caused by pituitary tumor or ectopic secretion caused. By bronchial carcinoid tumor)
What causes Cushing’s Syndrome?
Exogenous administration of glucocorticoids
*General appearance of pt with Cushing’s
Moon face
Buffalo hump
Truncal obesity
Weight gain
Pathologic fractures (makes bones porous b/c pulls out Ca)
Paper-like skin
Striae
Bruising
*Diagnostics of Cushing’s
Serum test looking for:
*Increased serum cortisol, Na, blood sugar
*Decreased serum calcium, potassium, lymphocytes
CT, MRI looking for tumor
*Client problems for pts with Cushing’s
Fluid volume overload
Fatigue (nutrition not good)
Body image disturbance
Risk for injury (fractures)
Risk for infection
Risk for impaired skin integrity
Treatment options for pts with Cushing’s disease
Medications
Radiation
*Surgery = best therapy
*Nursing actions for pt’s post-op after adrenal tumor removal
Lifelong hormone replacement if bilateral adrenalextomy
Hormone replacement for 1-2 yrs if unilateral adrenalectomy
Medic-alert bracelet
Additional hormones may be needed in times of stress
What is a pheochromocytoma?
Catecholamine-secreting (epi and norepi) tumor of the chromaffin cells usually found in the adrenal medulla
Patho of a pheychromocytoma
Excess secretion of epinephrine and norepinephrine causing severe symptoms (extremely high BP) and even death
S/S of a pt with pheochromocytoma
Hyperglycemia
N/V
Palpitations
*Hypertension
Apprehension
HA
Sweating
Psychoneurosis
Diagnostics for pheochromocytoma
Increased urinary catecholamines (epi/norepi)
Elevated serum catecholamines
CT scan
MRI
Interventions to treat pheochromocytoma
*Adrenalectomy is treatment of choice (removal of adrenal gland)
*Pt will likely be given alpha-adrenergic blockers first for stabilization of BP for 2-3 weeks
Nursing actions for caring for a pt with pheochromocytoma
- Altered tissue perfusion: peripheral (vascular checks, monitor VS)
- Altered comfort (HA): *quiet dark room away from nurse’s station, analgesics, avoid interruptions, limit visitors
- Potential for injury r/t sustained HTN: *Limit activity, avoid caffeine, smoking, sudden position changes, VS, neuro assess, BS checks
*Do not palpate abdomen (causes sudden release of epi/norepi causing HTN crisis)
