Final answer:
To minimize back strain while moving heavy objects, the radiographer should push the object while keeping it close to their body and using their legs to lift, maintaining a straight back.
Step-by-step explanation:
To reduce the back strain that can result from moving heavy objects, the radiographer should not hold the object away from his or her body, nor should they bend at the waist to pull. These methods can lead to back injuries. The correct way to move heavy objects to minimize back strain is to get close to the object, use the legs to lift rather than bending at the waist, maintain a straight back, and push the object rather than pulling it whenever possible. Pushing is generally easier on the back than pulling because it allows the individual to use their body weight to aid in the movement, hence option (D) push the object is the correct answer.
