The nurse is teaching a group of older adults at a community center about bacteremia. The nurse includes which of the following as a major risk of bacteremia for the older client?
1. Pneumococcal bacteria
2. Undiagnosed or inadequately treated infections
3. Leukocytosis on the complete blood count (CBC)
4. Elevated temperature
2. Undiagnosed or inadequately treated infections
Rationale:
Bacteremia occurs when pathogens are introduced into the blood circulation as a complication from pneumonia, urinary tract infection, or skin infections. The infection is spread throughout the body once it reaches the bloodstream. The most common organisms causing bacteremia are Escherichia coli, Proteus, and Klebsiella. The diagnosis is confirmed by blood culture, although one would expect to see leukocytosis if the client is able to mount an immune response. The temperature does not spike but is usually a low-grade fever. The client frequently presents with altered mental status.
