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)

The SIMTICS modules are all easy to use and web-based. This means they are available at any time as long as the learner has an internet connection. No special hardware or other equipment is required, other than a computer mouse for use in the simulations. Each of the SIMTICS modules covers one specific procedure or topic in detail. Each module contains:

  • an online simulation (available in Learn and Test modes)
  • descriptive text, which explains exactly how to perform that particular procedure including key terms and hyperlinks to references
  • 2D images and a 3D model of applied anatomy for that particular topic
  • a step by step video demonstration by an expert
  • a quiz
  • a personal logbook that keeps track of all the modules the learner has studied and how long
