A nurse is reviewing the medical record of a client who just received a dose of IV filgrastim. The client has cancer and is receiving cytotoxic chemotherapy. For which of the following findings should the nurse complete an incident report?

Filgrastim is a granulocyte colony-stimulating factor (G-CSF) used to stimulate the production of neutrophils and reduce the duration of neutropenia. It acts on hematopoietic cells to increase phagocytic activity, but its timing relative to cytotoxic chemotherapy is critical to prevent drug interaction. Rationale: A. A decreased neutrophil count is the primary indication for administering filgrastim, not a reason for an incident report. The medication is specifically intended to treat or prevent febrile neutropenia in clients undergoing myelosuppressive therapy. Finding a low absolute neutrophil count justifies the use of the growth factor to boost the client's immune defense. B. Filgrastim vials are stable at room temperature for up to 24 hours depending on specific manufacturer guidelines. Leaving the vial out for only 2 hours does not compromise the integrity of the medication or constitute a medication error. Therefore, this action does not necessitate an incident report as the medication remains safe for administration to the client. C. Filgrastim should not be administered within 24 hours before or after the administration of cytotoxic chemotherapy. Giving the medication only 12 hr after chemotherapy is a significant timing error that can interfere with the effectiveness of the treatment and worsen marrow suppression. The nurse must complete an incident report to document this violation of the safety protocol for colony-stimulating factors. D. Nausea is a common side effect of chemotherapy and can also occur with filgrastim, though it is not a reason for an incident report. Incident reports are reserved for errors, accidents, or unexpected hazardous events, not for documenting known, documented adverse reactions. The nurse should manage the nausea with antiemetics rather than filing an administrative error report.
