Question

A radiographer prepares to perform an AP projection of the distal femur on a patient with a suspected femoral fracture. Which represents the best approach for positioning both the patient and the x-ray tube?

A. Rotate the leg 15 degrees medially; place the cathode end of the tube toward the foot.
B. Rotate the leg 15 degrees medially; place the anode end of the tube toward the foot.
C. Do not rotate the leg; place the anode end of the tube toward the foot.
D. Do not rotate the leg; place the cathode end of the tube toward the foot.

Answer 1

The best approach for positioning both the patient and the x-ray tube for an AP projection of the distal femur on a patient with a suspected femoral fracture is not to rotate the leg and place the anode end of the tube toward the foot.

Step-by-step explanation:

When performing an AP projection of the distal femur on a patient with a suspected femoral fracture, the best approach for positioning both the patient and the x-ray tube is option C: Do not rotate the leg; place the anode end of the tube toward the foot. By not rotating the leg, the radiographer ensures proper alignment and prevents any distortion of the image. Placing the anode end of the tube toward the foot helps to minimize the amount of scatter radiation that reaches the image receptor, resulting in a clearer and more accurate image of the distal femur.
