Final answer:
The absolute monocyte count for a patient with a WBC count of 10,000/µL and 30% monocytes is 3,000 cells/µL, which is option C.
Step-by-step explanation:
To calculate the patient's absolute monocyte count, we use the given percentage of monocytes in the total white blood cell (WBC) count. We know the patient has a WBC count of 10,000/μL with 30% being monocytes. To find the absolute count, we perform the following calculation:
- Multiply the total WBC count by the percentage of monocytes (expressed as a decimal).
- 10,000/μL × 0.30 = 3,000/μL.
Therefore, the patient's absolute monocyte count is 3,000 cells/μL, which corresponds to option C.
Note: An abnormally high count of monocytes can indicate the presence of certain infections or chronic diseases, suggesting the importance of these cells in the body's immune response
