What is the joint of interest on the AP oblique knee with medial rotation?
 
 distal tibiofibular joint
  patellofemoral joint
  proximal tibiofibular joint
  femorotibial joint

Question 2

The recommended lead equivalency for gonadal shielding when kVp values are less than 100 is:
 
 0.25 mm
  0.50 mm
  0.75 mm
  1 mm

Answer to Question 1

proximal tibiofibular joint

Rationale: The AP oblique knee with medial rotation places interest on the proximal tibiofibular joint. The joint space should open or nearly open with correct rotation of the part.

Answer to Question 2

0.25 mm

Rationale: 0.25 mm lead equivalency is recommended with kVp values less than 100 . 0.50 mm lead equivalent with kVp 100-150 and 1.0 mm lead equivalent with kVp greater than 150.
