differential diagnosis, or differential, is a working list of potential problems that can be associated with
the initial or chief complaint. Establishing a differential diagnosis is a critical step in providing safe,
quality care. This evolving process of clinical reasoning and decision making involves examining the

requests a stat PMHNP consult. In speaking with the PMHNP, the client describes persistent feelings of
sadness and hopelessness. She states that she often wonders if her husband would be happier if she
wasn't around anymore since she's never happy and sometimes thinks about what it would be like to

Complete Blood Count - VERIFIED ANSWER The CBC is a serum diagnostic test that measures red blood
cells, white blood cells, hemoglobin, hematocrit, and platelets. The CBC includes a differential of the
white blood cells. A CBC is often included as part of routine health screening or to obtain information
related to specific conditions. In mental health, the CBC is used to rule out medical conditions that may
present with symptoms that can be attributed to both medical and psychiatric diagnoses. For example,
the CBC can help rule out anemia as a cause for depressive symptoms and fatigue or rule out infection
as a cause of acute mental status changes. The CBC is also used to monitor certain treatment regimens.
For example, some medications, such as clozapine, require routine analysis of absolute neutrophil count
and platelet levels.
