Medical Surgical Labs CBC #4
The nurse is reviewing the labs of a client who is receiving vancomycin for Clostridium difficile. Which data suggests the treatment is effective?
- WBC 4000
This answer is not correct because this lab value is too low. White blood cells should be between 5,000-10,000.
- WBC 4500
- WBC 8000
This answer is correct because this is a normal white blood cell count. It is between 5,000 and 10,000. This is evidence that the treatment is effective.
- WBC 12,000
This answer is not correct because this lab value is too high. White blood cells should be between 5,000-10,000.
Vancomycin is an anti-infective given intravenously. For it to be effective, the white count would be in normal range, between 5000-10,000.
Normal WBC ranges between 5,000-10,000. Below 5,000 is called leukopenia. This indicates the client has a viral infection or cancer in the body. Having leukopenia places the client at risk for further infection. WBC above 10,000 is called leukocytosis. This is brought on by viral or bacterial infection, trauma, stress, inflammation, and asplenia. A normal white cell count post-treatment would indicate the infection is under control and the treatment was effective.
