Practice Question
Which laboratory parameter should the nurse monitor in a patient taking linezolid (Zyvox) to prevent a serious complication of therapy?
Answer Choices:
Correct Answer:
Complete blood count
Rationale:
💥Linezolid (Zyvox) is an oxazolidinone antibiotic used for resistant infections like MRSA and VRE.
💥A serious complication of linezolid therapy is bone marrow suppression, leading to thrombocytopenia, anemia, or leukopenia.
💥Monitoring the complete blood count (CBC) helps detect these complications early and guides dose adjustments or discontinuation.
💥Alkaline phosphatase relates to liver function, serum creatinine to kidney function, and peak/trough levels are unnecessary since linezolid dosing is not guided by drug levels.
💥Regular CBC monitoring (weekly in long-term therapy) is the best way to prevent severe hematologic adverse effects.
