MOSBY CT EXAM
What type of clinical history should be documented? - ANSWER Recent procedures, surgeries,
symptoms, traums, area of pain
______ is key to any successful patient interaction - ANSWER communication
What should a patient do directly prior to the contrast studies - ANSWER Empty bladder
A patient is required to perform informed consent before the start of any invasive procedure.
Patient consent may be deemed "informed" only when what is explain to the patient - ANSWER
Risk, benefit, alternatives in a comprehensive language
What is implied consent? - ANSWER When a patient is in need of immediate medical services

cardiac cycle refers to - ANSWER all events associated with blood flow through the heart in
one beat
It is the _____ of the cardiac cycle that determines the patients heart rate - ANSWER
Frequency
Diastole refers to - ANSWER relaxation of heart muscle
Systole refers to - ANSWER contraction of the heart muscle
,Three distinct stages of the cardiac cycle - ANSWER Atrial systole, ventricular systole, complete
cardiac diastole
atrial systole - ANSWER contraction of the left and right atria (p wave)
ventricular systole - ANSWER Contraction of the left and right ventricles(QRS Complex)

Cardiac CT images are typically acquired during which phase of the heart's cycle? - ANSWER
diastolic (relaxation) phase
The heart optimally imaged with the least artifact from motion during its period of relaxation,
otherwise known as the diastolic phase of the cardiac cycle.
