This module teaches you about pharmacology and the role of the radiologic technologist in administering drugs for radiologic procedures

Some radiographic examinations involve the administration of intravenous (IV) contrast media, and it is becoming more common for radiologic technologists to administer the pharmocological agent, rather than the physician or radiologist. Therefore it is important for the technologist to have a basic understanding of pharmacology principles and how to perform IV cannulation. This module teaches you about pharmacology and the role of the radiologic technologist in administering drugs for radiologic procedures. Read about the procedures, watch the video demonstration, and explore the relevant anatomy. The online simulator, available in test and practice mode, provides a safe environment to learn and practice the steps for venous cannulation. This module is an ideal resource if you are studying for the American Registry of Radiologic Technologists® (ARRT) registry exams.

You’ll learn

to describe basic pharmacological principles such as naming, classification, dosing and charting practices
to identify the different routes of drug administration
to explain the concepts of pharmacokinetics and pharmacodynamics
the role of a radiologic technologist in administering pharmacological agents to patients
to practice, perfect and test your skills in performing venous cannulation for administering contrast media
about the different options for patients with procedural anxiety
how to identify adverse reactions and how to respond in a medical emergency
much more (see “content details” for more specific information)
