Part 4 Flashcards
These are high-density pharmacologic agents used to visualize low-contrast tissues in the body, such as the vasculature, kidneys, gastrointestinal (GI) tract, and biliary tree.
RADIOPAQUE CONTRAST AGENTS (ROCM)
Used in patients who have experienced an acute ischemic event to either their heart or their brain in the past.
ANTIPLATELET
oral medications for inhibiting platelet effects.
ASPIRIN, CLOPIDOGREL, & DIPYRIDAMOLE
IV medications for inhibiting platelet function.
EPTIFIBATIDE, ABCIXIMAB, & TIROFIBAN
• Convenient and safe method of giving drugs when the oral method is unsuitable, as when the patient is a small child or is unconscious.
• Avoids irritation of the upper GI tract and may promote higher bloodstream drug titers because venous blood from the lower part of the rectum does not traverse the liver.
RECTAL ROUTE
Used to actively break up a newly formed clot, such as found in patients with acute myocardial infarction, acute stroke secondary to blood clot, or lower leg ischemia.
THROMBOLYTIC MEDICATION
IODINE atomic number
BARIUM atomic number
53
56
usually selected to produce high-contrast radiographs of the blood vessels or genitourinary tract.
LOW-KILOVOLTAGE (below 80 kVp)
used in GI examinations not only to reveal the presence of the organ, but also to penetrate the contrast media to see the walls and inner structures.
HIGHER KILOVOLTAGE (above 90 kVp)
Used to treat both acute and chronic pain syndromes.
COMMON SUBCLASSES:
NARCOTIC
NONSTEROIDAL ANTI-INFLAMMATORY DRUGS (NSAIDs)
MUSCLE RELAXANTS
ACETAMINOPHEN
ANALGESIC
Stimulates central nervous system receptors known as opioid receptors and cause a decrease in the perception of pain.
NARCOTIC
Stimulate central nervous system receptors known as opioid receptors and cause a decrease in the perception of pain.
NONSTEROIDAL ANTI-INFLAMMATORY DRUGS (NSAIDS)
Treat pain associated with muscle spasms. These are often used in ailments such as whiplash, spinal cord injury with spastic muscles, and muscular strains or sprains.
MUSCLE RELAXANTS
It is the movement of water across a semipermeable membrane.
OSMOSIS
It controls the distribution and movement of water between body compartments. It is also the number of milliosmales per kilogram of water (mOsm/kg), or the concentration of molecules per weight of water.
OSMOLALITY
A low-potency pain reliever and must not exceed 4000 mg per day because it is associated with severe liver damage at high doses can also cause renal and cardiac. Long-term use of high doses damage.
ACETAMINOPHEN
The imaging technologist should use _____ method that includes the assessment of patient medical history and current renal function status.
Screening
Drugs that block histamine from producing adverse effects such as itching, inflammation, respiratory distress, and overall allergic reactions.
ANTIHISTAMINE
