Which represents the best approach for positioning both the patient and the x-ray tube? A. Rotate the leg 15 degrees medially; place the cathode end of the tube toward the foot. B. Rotate the leg 15 degrees medially; place the anode end of the tube toward the foot. C. Do not rotate the l...

RADT 1200 Test Review Questions and Revised Answers All Correct The 1980 BEIR report revealed that the majority of stochastic effects and genetic effects at low dose levels from low-LET radiation appear to follow what type of curve? - Answer-linear quadratic non-threshold dose response curve The 1990 BEIR report suggested that radiation exposure and associated risk be represented by which curve? - Answer-linear nonthreshold The _____________ curve implies that the biological response t...

1. A patient’s nutritional intake and laboratory results reflect hypoalbuminemia. This is critical to prescribing because: Distribution of drugs to target tissue may be affected. 2. Drugs that have a significant first-pass effect: Are rapidly metabolized by the liver and may have little if any desired action 3.The route of excretion of a volatile drug will likely be the: Lungs 4. Medroxyprogesterone (Depo Provera) is prescribed intramuscularly (IM) to create a storage reservoir Increase ...

Pharmicodynamics - Answer-What the body does to a drug What is the advantage to expressing drug dose as a log? - Answer--we can go from 0.01 ug to 100 ug in one graph -it allows us to express drug doses across a very wide range -it expands the concentration at the lower axis - our ability to look at the body's response at the lower doses - because all of the action is happening at the left side of the graph we want to be able to finely grade the graph on the side of the graph where the res...

Pharmacodynamics Ans: the study of the biochemical and physiologic effects of drugs and the molecular mechanisms by which those effects are produced *the study of what drugs do to the body and how they do it Dose-Response Relationship definition Ans: relationship between the size of an administered dose and the intensity of the response produced -determines the minimum amount of drug we can use -the maximum response a drug can elicit -how much we need to increase the dosage in orde...

Every chemical can be toxic :: true Which of the following organ has the highest chemical metabolic activity? :: Liver The dominant system for distributing all toxicants is :: the circulatory system Which of the following is not a component of chemical carcinogenesis? :: remission An substance essential to life has what shaped dose-response curve? :: U Which of the following is not a component of a risk assessment. :: risk management Has endocrine disruption due to environmental chem...

The principal late effects of ionizing radiation on humans include tissue damage ic effects nant disease - ANS ic effects nant disease Late or long-term effects of radiation can occur in tissues as a result of chronic exposure or tissues that have survived a previous irradiation months or years earlier. These late effects, such as carcinogenesis and genetic effects, are "all-or-nothing" effects—either the organism develops cancer or it does not. Examples of late effects of ...
