|---|---|
| ALCS Stands For | Advanced cardiac life support |
| ADH Stands For | Antidiuretic Hormone |
| BLS Stands For | Basic Life Support |
| AHA Stands For | American Heart Association |
| CPR Stands For | Cardiopulmonary Resuscitation |
| ________ Increases blood pressure, dilates pupils, decreases ability to urinate and defecate | Alpha-1 (α1) |
| _______ Decreases blood pressure (when stimulated in the brain), causes constipation | Alpha-2 (α2) |
| _______ Increases heart rate, cardiac output, and dysrhythmias; causes fat to break down (lipolysis); releases renin hormone from the kidneys (may lead to increased blood pressure) | Beta-1 (β1) |
| ______ Decreases blood pressure, opens airways, causes constipation, inhibits uterine contractions, increases glucose production, releases insulin, contracts skeletal muscle | Beta-2 (β2) |
| Ratio of iodine atoms to osmotically active particles is 3:2 in ratio ________ | -1.5 Media |
| Ratio of iodine atoms to osmotically active particles is 3:1 in ratio________ | -3.0 Media |
| Why is iodine used so extensively in ROCM? | Because it absorbs x-ray photons, thus enhancing contrast |
| Why do intravascular ROCM tend to remain in the bloodstream? | Large molecules that cannot cross cell membranes |
| Why is iodamide meglumine used primarily for cholecystography and cholangiography? | Because it's excreted by the hepatobiliary system |
| High-osmolality ionic ROCM, low-osmolality nonionic ROCM, and low-osmolality ionic ROCM are the 3 broad categories of ______ | Intravascular ROCM |
| When are diatrizoate solutions most often used? | When barium sulfate suspension is potentially harmful, such as in GI perforation, or when computed tomography is being used because of less artifact production |
| What are the names of the major iron-containing paramagnetic agents? | Ferumoxtran-10 (Combidex), Iron Oxide (Clariscan), and Ferumoxytol |
| What are the microbubble agents generally used for in radiologic science? | Octafluoropropane Albumin (Optison) and Perflutren (Definity) |
| DSA Stands For | Digital Subtraction Angiography |
| PEA Stands For | Pulseless Electrical Activity |
| ARF Stands For | Acute Renal Failure |
| Why is a history of previous exposure to a drug or ROCM not enough to predict the possibility of a hypersensitivity reaction? | Mast cells may respond to the first exposure with anaphylaxis |
| What should be done to ensure safe administration of two or more incompatible drugs? What should be done if information on drug-drug compatibility is not available? | Assume incompatibility and flush line with saline to prevent drug-drug contact |
| ROCM Stands For? | Radiopaque Contrast Media |
| MRI Stands For? | Magnetic Resonance Imaging |
