A nurse is reinforcing teaching about laboratory testing with a client.Which of the following findings should the nurse include as an indicator of infection?

Choice A rationale:Decreased platelets are not typically an indicator of infection. Platelet levels may decrease in conditions like thrombocytopenia, but they are not a specific indicator of infection.Choice B rationale:Increased erythrocyte sedimentation rate (ESR) is an indicator of infection. An elevated ESR is a nonspecific marker of inflammation in the body, which can be seen in response to infection, among other conditions.Choice C rationale:Decreased hemoglobin is not typically an indicator of infection. Hemoglobin levels may decrease in conditions like anemia, but they are not a specific indicator of infection.Choice D rationale:Increased iron levels are not typically an indicator of infection. Iron levels can vary for various reasons, but they are not a direct marker of infection.
