Question

An injection rate of __________ cc/sec. will maintain a dense bolus of IV contrast media for a CTA examination and will be tolerated by most patients?

1) 8-10
2) 7-8
3) 4-5
4) 1-2

Answer 1

An appropriate IV contrast media injection rate for a CTA examination tolerated by most patients is typically in the range of 4-5 cc/sec.

Step-by-step explanation:

The student has asked about the appropriate injection rate of IV contrast media for a CTA (computed tomography angiography) examination. While this question does not provide clear context for an exact numerical answer, the injection rates for contrast media typically range between 4 to 5 cc/sec, up to 8 cc/sec, depending on the specific protocols of the imaging facility and the patient's individual tolerance and health condition. However, based on the available choices, an injection rate of 4-5 cc/sec is commonly used in practice and will be tolerated by most patients for maintaining a dense bolus of IV contrast media.
