A total volume of 125 mL of an iodinated contrast agent is administered intravenously via automatic injector in 50 seconds. The flow rate for this injection is:
A: 0.75 mL/sec
B: 1.25 mL/sec
C:1.75mL/sec
D: 2.5 mL/sec
D: 2.5 mL
This is calculated by 125 divided by 50 to get 2.5mL

D: 1, 2, and 3
D: 1,2, and 3. Age, sex, and race can affect a patient’s GFR

Which of the following describes the situation in which an assumption is made that an unconscious person consents to treatment?
A: informed consent
B: witnessed consent
C: patient proxy
D: implied consent
D: implied consent

B: QRS complex
C: alpha wave
D: T wave

During CT arthrgraphy, iodinated contrast media is injected into the
A: joint space
B: intrathecal space
C: subarachnoid space
D: venous bloodstream
C: subarachnoid space
Which of the following is considered one of the iso-osmolar contrast media (IOCM)?
A: iodixanol
B: iopamidol
C: iohexol
D: ioversol
A: iodixanol

B: olecranon fossa
C: retroulnar space
D: antecubital space
D: antecubital space
The potentially serious decline in renal function after giving IV contrast is called?
A: anaphylaxis
B: bronchopspams
C: contrast induced nephrotoxicity (CIN)
D: urticaria
C: contrast induced nephrotoxicity (CIN)
Advantages of a saline flush after giving IV contrast are:
1. Reduction in required contrast agent dose
2. reduction of possible CIN
3.reduction of streaking artifacts from dense contrast agents
A. 1 only
B. 3 only
C. 2 and 3 only
D. 1,2, and 3
D. 1,2, and 3
All of them!

A. 40-60 mmHg
B. 60-90 mmHg
C. 80-120 mmHg
D. 95-140 mmHg
B. 60-90 mmHg

B. Intrathecal space
C. Subarachnoid space
D. Intra-articular space
D. Intra-articular space
When contrast is administered directly into a joint space (THIS ISN’T THE SPINE), this is referred to as an intra-articular injection
