Applied Hematologic and Immunologic Physiology
Both the hematologic system and the immune system depend on healthy bone marrow function. The hematologic system consists of an intricate network of vessels and fluid. The components of the immune system function to protect the body against invasion by foreign and harmful substances. This course provides an overview of these systems, including the components of the blood, blood coagulation, and the structure and function of the immune system. (60 minutes)

Common Hematologic Disorders
Hematologic disorders include disorders of the white and red blood cells, as well as most bone marrow failure. This course identifies major blood cell and bone marrow disorders, and reviews the clinical manifestations and medical interventions essential to diagnosis and treatment. (51 minutes)

Common Immunological Disorders
The human immunodeficiency virus (HIV) is one of the most widespread immunological disorders in the world. People with HIV typically suffer from the clinical manifestations of opportunistic infections. Healthcare delivery to patients with HIV is focused on treating HIV and managing and preventing the infections associated with the disease. This course provides a general overview of the etiology and pathophysiology of HIV. It also discusses the transmission of the disorder, common opportunistic infections related to HIV, and management of patients with HIV. A case study provides for the application of the material learned in this course. (55 minutes)

Hyperthermia
This course acquaints the critical care nurse with the causes, types, and treatment of a variety of forms of hyperthermia, which is an abnormal increase in body temperature.  It details the mechanisms of thermoregulation and the pathophysiologic changes that result when these mechanisms are overwhelmed or fail. In addition, this course outlines the clinical findings, treatment, and nursing care of heat exhaustion and heatstroke. Lastly, it explores the recognition and treatment of secondary hyperthermia. The general effects of uncontrolled hyperthermia on body systems can lead to multisystem organ failure and eventually become life threatening. (70 minutes)

Hypothermia
This course defines hypothermia and describes how the body is affected when its temperature falls below normal. In the critical care setting hypothermia can be life threatening, so it is essential to understand the signs, symptoms, and management involved for your patient. When the human body becomes hypothermic, specific physiologic mechanisms work to maintain normal core body temperature. If these mechanisms are overwhelmed, however, it will be up to the critical care staff to maintain the patient's normal core body temperature (100 minutes)
