What is the main concern when caring for a patient undergoing chemotherapy?

The primary concern when caring for a patient undergoing chemotherapy is the risk of infection due to immunosuppression. Chemotherapy works by targeting rapidly dividing cells, which includes not only cancer cells but also some healthy cells such as those found in the bone marrow. This interference can lead to a decrease in white blood cells, specifically neutrophils, which play a crucial role in the body’s immune response.

When the white blood cell count drops, the patient becomes more vulnerable to infections from bacteria, viruses, and fungi. This is particularly significant because infections can lead to serious complications and may require hospitalization, additional treatments, or even lead to life-threatening situations.

While nausea and vomiting, hair loss, and anemia are also common side effects of chemotherapy and present their own challenges, the immediate threat posed by potential infections is a more acute concern needing vigilant monitoring and management. Therefore, preventive measures such as hand hygiene, avoiding crowds, and closely monitoring for signs of infection become critical aspects of patient care during chemotherapy.
