Cataractogenesis, life span shortening, embryologic effects, and carcinogenesis are examples of: A. short-term somatic effects B. genetic effects C. acute radiation syn...

A radiologic technologist performs actions according to the best interests of the patient. To which principle of the American Registry of Radiologic Technologists (ARRT) Code of Ethics does the radiologic technologist adhere? : Principle 5 - states that the radiologic technologist acts in the best interest of the patient.

About how long does a coronary angiography last? : 30 to 60 minutes. A coronary angiography is used to check the blood flow from the arteries into the heart. A contrast material is inserted through at catheter and the patient is then x-rayed to check how well the contrast material is flowing. The doctor can then check for any blockages. The procedure will last only about 30 to 60 minutes. The catheter is first inserted into ______ for a pulmonary angiogram? : Vein Which of the followi...

Torts are also known as ________. : Personal Injury Law If a patient is apprehensive about being injured, or a radiographer causes fear in the patient, it is known as ________. : Assault 2 Unlawful touching or touching without consent, harm resulting from physical contact with the radiographer, and imaging the wrong body part or...

Which of the following examinations require(s) special identification markers in addition to the usual patient name and number, date, and side marker? 1. IVU 2. Tomography 3. Abdominal survey : 1, 2, and 3 What should you do if you discover while taking the patient history that a patient scheduled for an intravenous urogram (IVU) takes Glucophage (metformin hydrochloride) daily? 1. Proceed with the examination. 2. Reschedule the examination until the patient has been off Glucophag...

The radiation intensity from a point source of 99mTc is 9 mR/hr at 3 m from the source. If the distance is changed to 9 m, what is the new radiation intensity? A. 0.5 mR/hr B. 1.0 mR/hr C. 2.0 mR/hr D. 3.0 mR/hr : B. 1.0 mR/hr The inverse square law results in the radiation intensity quadrupling if the distance from the source is halved, or it results in the radiation intensity decreasing to one fourth of its value if the distance is doubled. A technologist is sitting near a bone mi...
