By the end of this module, you’ll be able to:

- List four categories of disease agent sources

- Discover conditions when disease transmission is likely to occur

- Describe the means of disease transmission in a given situation

In this animated activity, learners examine the symptoms of four cardiac conditions: coronary artery disease, myocardial infarction, congestive heart failure, and valvular disease.

Learners use peripheral vascular assessment data to examine characteristics of these four conditions: peripheral arterial disease, deep vein thrombosis, chronic venous insufficiency, and acute arterial occlusion. A matching exercise completes the learning object.

At the end of this lesson you will be able to

- Explain what biosecurity means.

- Describe why biosecurity is important.

- Identify what kinds of disease agents we try to prevent or control with biosecurity.

- Demonstrate disease agent-host-environmental interactions that result in disease.

In this module, you'll be able to :

- Identify five routes of infection

- Describe how diseases are transmitted in animals

By the end of this module, you'll be able to:

- Identify actions that can reduce biosecurity risk

- Develop a biosecurity action plan for a farm

- Select the most cost effective strategies

In this screencast, learners examine the action of insulin and other antidiabetic medications.

In this interactive and animated object, learners classify a number of diagnoses by shooting a soccer ball into goals marked "Medical" and "Nursing."

Learners will examine how cardiac markers are used in the diagnosis of cardiac disease.
