Systematic CBC interpretation for anemia patterns and non-hematologic WBC shifts

[Dennis_T]

I'm a new nurse on a general medical floor, and I'm trying to build confidence in interpreting complete blood count results independently, especially when they show subtle abnormalities. I understand the basic ranges, but I struggle with correlating specific patterns, like a low MCV with a high RDW, to likely clinical conditions. For more experienced clinicians, what's your systematic approach to analyzing a CBC beyond just flagging high or low values? How do you differentiate between causes of anemia based on the indices, and what are the most common non-hematologic conditions that can cause significant shifts in the white cell differential? I'd also appreciate any resources for practicing interpretation with real patient cases.
