NURSING CONSIDERATIONS
Assess:

• 
Potassium, blood glucose, urine glucose while patient receiving long-term therapy; hypokalemia, hyperglycemia

• 
Weight daily; notify prescriber if weekly gain of >5 lb

• 
B/P q4hr, pulse; notify prescriber if chest pain occurs

• 
I&O ratio; be alert for decreasing urinary output, increasing edema

• 
Plasma cortisol levels with long-term therapy; normal level: 138-635 nmol/L SI units when drawn at 8
AM

• 
Infection:
increased temp, WBC, even after withdrawal of medication; product masks infection

• 
Potassium depletion:
paresthesias, fatigue, nausea, vomiting, depression, polyuria, dysrhythmias, weakness

• 
Edema, hypertension, cardiac symptoms

• 
Mental status: affect, mood, behavioral changes, aggression

• Adrenal insufficiency:
nausea, vomiting, lethargy, restlessness, confusion, weight loss, hypotension before, during treatment; HPA suppression may be precipitated by abrupt withdrawal

Evaluate:

• 
Therapeutic response: ease of respirations, decreased inflammation

Teach patient/family:

• 
That emergency ID as steroid user should be carried

• 
To notify prescriber if therapeutic response decreases; that dosage adjustment may be needed

• 
Not to discontinue abruptly; that adrenal crisis can result; to take product exactly as prescribed

• 
To avoid OTC products: salicylates, cough products with alcohol, cold preparations unless directed by prescriber

• 
About cushingoid symptoms

• About the symptoms of adrenal insufficiency: nausea, anorexia, fatigue, dizziness, dyspnea, weakness, joint pain
