SET A+
✔✔If a patient has excessive external rotation of one foot, a fractured hip may be
indicated.
True
False - ✔✔TRUE
✔✔Less abduction of femora of only 20° to 30° from vertical provides for the least
foreshortening of femoral necks when performing the AP bilateral "frog-leg" projection.
True
False - ✔✔TRUE
✔✔Generally, gonadal shielding for females cannot be used for an initial AP pelvis for
pelvic trauma due to the possibility of covering pertinent anatomy.
• True
False - ✔✔TRUE
