NURSING CONSIDERATIONS
Assess:


 
Myelosuppression:
ANC, platelets; in chronic phase, if ANC <1 × 10
9
/L and/or platelets <50 × 10
9
/L, stop until ANC >1.5 × 10
9
/L and platelets >75 × 10
9
/L; in accelerated phase/blast crisis, if ANC <0.5 × 10
9
/L and/or platelets <10 × 10
9
/L, determine whether cytopenia is related to biopsy/aspirate, if not, reduce dose by 200 mg, if cytopenia continues, reduce dose by another 100 mg; if cytopenia continues for 4 wk, stop product until ANC ≥1 × 10
9
/L, monitor CBC weekly × 8 wk, then monthly


 
Hepatotoxicity:
monitor LFTs before treatment and monthly; if liver transaminases >5 × IULN, withhold until transaminase levels return to <2.5 × IULN

• 
Signs of fluid retention, edema:
weigh, monitor lung sounds, assess for edema; some fluid retention is dose dependent, may result in CHF, congestive cardiomyopathy, decreased injection failure


 
QT Prolongation:
more common in those with hypokalemia, hypomagnesemia, congenital long QT syndrome, those taking products that prolong QT; correct electrolyte imbalances before use

Evaluate:

• 
Therapeutic response: decrease in leukemic cells or size of tumor

Teach patient/family:


 
To report adverse reactions immediately: SOB, swelling of extremities, bleeding, bruising

• 
About reason for treatment, expected results


 
To use contraception (pregnancy category D), to avoid breastfeeding; men should use condoms

• 
To take at same time of day, not to crush or chew, do not use grapefruit juice
