Differential Dx
Diagnostic reasoning is the process of questioning one's thinking to determine if all
possible avenues have been explored and if the conclusions that are drawn are based
on evidence. This is a critical step for providers who are trying to uncover a cause, or
diagnosis, for their clients' signs and symptoms. The provider's initial hypothesis is
known as the differential diagnosis. The 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 client's presentation, clinical data, and when appropriate, screening and
diagnostic test results to distinguish one disease from another and arrive at the correct
diagnosis. The Diagnostic and Statistical Manual of Mental Disorders (DSM-5-
TR)provides guidance for identifying psychiatric diagnoses

emergency department (ED) physician is concerned that the client may have
intentionally crashed her car and 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
just take a handful of sleeping pills and go to sleep forever. The client reports a previous
suicide attempt when she was 16 but denies that she is considering killing herself right
now.
Based on the client's ASQ score, what is the most appropriate response?

Complete Blood Count
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.
Normal Range of:
Red blood cells
Hemoglobin
Hematocrit
Reticulocytes
Red blood cells: 4.5-6.0 million/microliter
Hemoglobin: 12-18 grams/100 mL
