NR 547 Differential Dx Midterm Exam With Complete Solutions Differential Dx CORRECT ANSWERS 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.

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.

The CMP is also used to monitor the effects of medications, such as antipsychotics, on liver function and glucose levels.Normal CMP Levels Electrolytes
