Question 24
Regular
When assessing a patient for signs of an infection the nurse recognizes which laboratory result as indicative of an infection?
Correct!
Incorrect
The correct answer is: B
Rationale
Increased white blood cell count. This laboratory result indicates the body's immune response to an infection, typically reflecting a rise in leukocytes like neutrophils, which combat pathogens effectively.
A: Lowered red blood cell count. A decrease in red blood cells often signifies anemia or other conditions but does not directly correlate with infection or immune response.
C: Lowered white blood cell count. A reduction in white blood cells can suggest immunosuppression or certain viral infections, which do not indicate an active infection requiring immune response.
D: Increased red blood cell count. Elevated red blood cells usually relate to dehydration or chronic hypoxia rather than an infection, making it an unreliable indicator of infectious processes.
