Final answer:
The absolute neutrophil count (ANC) is calculated by multiplying the total WBC count by the percentage of neutrophils. With a total WBC count of 15,800 and a neutrophil percentage of 30%, the ANC would be 4,740.
Step-by-step explanation:
The question pertains to calculating the absolute neutrophil count (ANC), which is a measurement of the number of neutrophils in the blood. Neutrophils, being one of the types of white blood cells (WBC), play a critical role in the immune system by combating infections and are typically the most abundant type of white blood cells. To calculate the ANC, we use the total WBC count and the percentage of neutrophils. In this case, the total WBC count is given as 15,800 and the neutrophil count as 30% of the total WBC.
To calculate ANC: ANC = (Total WBC count) x (Percentage of neutrophils) / 100
ANC = 15,800 x 30 / 100
ANC = 4740
Hence, the absolute neutrophil count is 4,740, which we can express as option 2 among the provided choices. It is important to note that normal ANC values typically range between 1,000 to about 7,000 neutrophils per microliter of blood, and the given count is within this normal range.
