NURSING CONSIDERATIONS
Assess:

• 
Blood studies: Hgb, WBC, platelets during treatment monthly; if leukocytes <3000/mm
3
or platelets <100,000/mm
3
, product should be discontinued or reduced; decreased hemoglobulin level may indicate bone marrow suppression

• 
Hepatic studies: alk phos, AST, ALT, amylase, bilirubin; for hepatotoxicity: dark urine, jaundice, itching, light-colored stools; product should be discontinued

• 
Serum creatinine/BUN, serum electrolytes, lipid profile, serum tacrolimus conc

 
Anaphylaxis:
rash, pruritus, wheezing, laryngeal edema; stop infusion, initiate emergency procedures

• 
QT prolongation:
ECG, ejection fraction; assess for chest pain, palpitations, dyspnea

Evaluate:

• 
Therapeutic response: absence of graft rejection; immunosuppression in patients with autoimmune disorders

Teach patient/family:
PO route

• 
To report fever, rash, severe diarrhea, chills, sore throat, fatigue; that serious infections may occur; to report clay-colored stools, cramping
(hepatotoxicity), nephrotoxicity,
signs of diabetes mellitus
