Pathophysiology
Pathophysiology explains how changes in normal cellular, tissue, organ, and system function produce disease. Connecting those mechanisms with symptoms, physical findings, laboratory abnormalities, and complications supports stronger diagnostic reasoning.
This index organizes condition-specific guides for DNP and advanced-practice nursing students. The guides are designed for focused review, comparison across conditions, and application to clinical assessment and differential diagnosis.
Each condition page can be used independently and includes its own supporting citations and APA 7 reference list.
How the Condition Guides Are Organized
Condition guides follow a consistent structure:
- Classification
- Etiology and risk factors
- Pathophysiology
- Clinical manifestations
- Diagnostic evaluation
- Differential diagnosis
- Management principles
- Red flags and serious complications
This repeated structure makes it easier to compare similar conditions and trace clinical findings back to the underlying mechanism.

- Severe combined immunodeficiency
- DiGeorge syndrome
- X-linked agammaglobulinemia
- Common variable immunodeficiency

Infectious Syndromes
- HIV infection and AIDS
- Infective endocarditis
- Meningitis

Use These Guides for Focused Review
These resources are intended to support education and clinical reasoning. They do not replace patient-specific assessment, current clinical guidelines, institutional protocols, or consultation with an appropriate clinician or specialist.
