What is an indication that a nurse must intervene when chemotherapy is administered?

A nurse must intervene when a patient appears lethargic after chemotherapy administration because lethargy can indicate several potential complications, including an adverse reaction to the chemotherapy, electrolyte imbalances, or a drop in blood cell counts such as anemia or neutropenia. These conditions can be serious and may require immediate assessment and intervention to prevent further complications or deterioration of the patient's condition.

Monitoring for signs of lethargy is crucial as it could also signal that the patient's overall performance status is declining. The presence of lethargy suggests a potential need for medical evaluation, including laboratory tests and supportive care measures, to address any adverse effects of the treatment and ensure the patient's safety.

In contrast, signs of adjustment, high energy levels, and increased appetite typically indicate a more positive response to chemotherapy or recovery from treatment and do not generally warrant immediate concern or intervention.
