Final answer:
Impaired WBC function due to Chemotherapy affects the immune response, risking infections. The WBC count is typically measured with a CBC and an ANC; an ANC of 1900 cells/μL may be acceptable for proceeding with treatment. Physical assessments can reveal symptoms of infection indicative of compromised immunity.
Step-by-step explanation:
When a patient is undergoing Chemotherapy, the function of their white blood cells (WBCs) that is impaired is the immune response. Chemotherapy drugs are cytotoxic and can decrease the production and function of leukocytes, leading to an increased risk of infections and impaired immune responses. The normal range for WBC count is typically between 4,500 to 11,000 cells per microliter of blood.
Lab tests to monitor include the Complete Blood Count (CBC) with differential, which measures the levels of different types of blood cells, including WBCs. Specifically, an Absolute Neutrophil Count (ANC) is crucial for monitoring neutrophil levels, which are vital in fighting infections. An ANC of 1900 cells per microliter is on the lower side of normal range but may allow for chemotherapy to proceed with caution, depending on the patient's overall condition and specific treatment regimen.
Physical assessments that reflect impaired WBC function include signs of infection, such as fever, chills, and the presence of opportunistic infections. These symptoms, along with laboratory results, help healthcare professionals assess the patient's immune function status and adjust chemotherapy treatment accordingly.
