RAD 2201 - Contrast Agents

This video discusses the concept of therapeutic equivalence; explains the differences among pharmaceutics, pharmacokinetics, pharmacodynamics, and pharmacognosy; and examines the phases of drug action. It outlines the effects of enterohepatic recirculation, differentiates between drug actions and effects, and describes differences in absorption rates of different types of oral medications. It also considers factors that affect an individual's ability to comply with a medication plan.

Explaining the concept of drug half life, this video looks at steady-state, peak, trough, and duration. It describes the process of drug absorption, discusses how the first pass effect impacts medication levels, looks at the possible effects of taking multiple medications, and compares such medication delivery methods as enteral, parenteral, topical, and inhalation. The video also considers the impact of chemical protein binding on medication availability and toxicity.

Describing three mechanisms of drug action, this video examines seven types of medication regimes. It outlines signs and symptoms related to adverse drug reactions and interactions, defines therapeutic range/index, and differentiates among drug-drug, food-drug, additive, synergistic, antagonistic, and incompatibility interactions.

This program traces the development of x-ray imaging from the early discovery of its fluorescing properties to modern digital imaging with flat panel displays. It explains the use of X-ray image intensifiers and provides an overview of their technical properties. It discusses types of flat-panel detectors, looking at their mechanisms, and considers safety protocols, system configurations, and general equipment adjustments. It also examines contrast agents and image evaluation.

Assisting with or directly administering medication is an important role of the personal caregiver and carries significant responsibility. In fulfilling this role effectively and safely, the caregiver becomes a vital member of the health care team. This program introduces safe and responsible medication practices. Topics include the “five rights” of medication administration, proper routes of administration, and the various techniques of managing and manipulating medicine consumption. Students will learn how to address the effects of medications—including intended effects, side effects, and allergic reactions—and how these should be documented.

Looking at common complications of procedural sedation medications, this video discusses when, why, and how to use such reversal medications as naloxone and flumazenil. It explains Joint Commission standards for using sedation; discusses how to prepare a child for procedural sedations; and points out special considerations and precautions for pediatric patients. It also outlines the discharge criteria from the American Academy of Pediatrics.

A complete review and demonstration of the procedure for venipuncture, including vein selection, needle insertion, and blood draw. Procedures shown in this series should only be performed by medical professionals with the appropriate training.

This video demonstrates the steps of venipuncture.
