, RCIS - XRay Exam Questions &
Answers (Grade A+)
How does KVp relate to scatter? -
correct answer ✅The higher the KVp, the greater the scatter
Who is at greater risk for tissue burns? -
correct answer ✅Those with collagen Vascular disease
Names 3 collagen vascular diseases -
correct answer ✅Diabetes
Hyperthyroidism
All types of arthritis
Why are collagen vascular diseases a concern when put under xray?
-
correct answer ✅Due to an increased amount of collagen within
cellular walls, a greater amount of radiation is absorbed and puts
patient at risk for tissue burns
