a. a greater distance from the lateral orbital margin to the lateral cranial cortex on the left side than on the right side.
b. a greater distance from the crista galli to the lateral cranial cortex on the right side than on the left side.
c. a greater distance from the right mandibular ramus to the cervical vertebrae than from the left mandibular ramus to the cervical vertebrae.
d. a greater distance from the lateral orbital margin to the lateral cranial cortex on the right side than on the left side.
Question 2
A PA cranial projection with poor positioning demonstrates the petrous ridges too superior to the supraorbital margins. How was the patient positioned for such a projection to be obtained?
1. The patient's chin was inadequately tucked.
2. The OML was not positioned perpendicular to the IR.
3. The patient's face was rotated toward the right side.
4. The patient's head was tilted.
a. 1 and 2 only
b. 2 only
c. 3 only
d. 2 and 4 only
