history of asthma or allergies
prior contrast reactions
patients who have been reported to have had reactions to gadolinium include
history of asthma or allergies
prior contrast reasctions
hemolytic anomalies
contrast agent reactions such as flushing, hives and nausea are called

keep your back straight
keep your knees slightly bent
log rolling is a method of moving patients with a suspected
vertebral column injury
the most common site injured by technologists while caring for patients is the
lumbrosacral spine
during the movement and transfer of patients urinary catheter bags should be placed
below the level of the urinary bladder
when venipuncture is performed
the contrast agent must ALWAYS be flushed through the syringe, and tubing used and needle before injection to avoid the administration of air into the vein
which of the following may cause a patient to experience a syncopial episode
anxiety
hunger
the diabetic patient who has excessive insulin in their body is said to have
hypoglycemia
if a patient has a cardiac arrest during MR imaging the technologist should
begin CPR while transferring the patient out of the scan room
during an emergency that occurs during MR imaging the technologist should
