A

From the carpus to the distal digits

80
Q

To prevent superimposition of the scapula and ribs in the caudocranial scapula of a Borzoi:

A

Rotate the patient’s sternum from the scapula about 10 to 12 degrees

81
Q

You are positioning for a right lateral pelvis of a Belgian Sheepdog. The femur that will be more magnified on the image is:

A

The left, because of increased object-film distance

82
Q

When positioning for this right lateral pelvis of the Belgian Sheepdog, you should position the hind limbs so that:

A

The right limb is pulled slightly cranially and the left slightly caudally

83
Q

A Poodle is exhibiting severe pain and trauma in the pelvis. Using a vertical beam, you should position so that your patient is in:

A

Dorsal recumbency with the hind limbs in a frog-leg position

84
Q

Center the VD frog-leg view of the Poodle:

A

Midline at the caudal pubis

85
Q

The hind limbs of this VD frog-leg view of the Poodle should be:
