GUIDEWIRES STUDY GUIDE EXAM
QUESTIONS AND ANSWERS
manufacturer - Answer-guidewires should be inspected before use, if defective they
should be set aside and returned to back to the ___________________.
J-guide wire - Answer-the __________ allows negotiation of tortuous vessels. The
purpose of the safety wire is to contain coils of the spring during manipulation , reducing
the risk of of kinking or separating
clotheslining - Answer-while the catheter is threaded over the guidewire, the
radiographer assists the radiologist by keeping the wire taut. This is referred to as:
