Critical Thinking Short Answer Question: Provide a well thought out short answer with specific details, vague answers will not receive full credit. When assisting & performing a portable AP chest radiograph in a tight room you notice that your co-worker is at an SID of 48″ and the SOD is 40″ on an elderly female patient of average size. What is the concern for the diagnosis on the potential radiograph? How can this be corrected to avoid a repeat examination and why?

As a radiographer, you are using a DR system that displays EI#’s as part of the DICOM header. The EI#s are calculated as directly proportional and linear to exposure. The image you have created shows marginal quantum noise and an EI# of 140. The exposure technique you used was 85 kVp@ 15 mAs. To improve image quality and eliminate the objectionable noise, your next step should be to

The peak power generated by any skeletal muscle increases with increasing velocities of movement up to a movement speed of 200-300 degrees per second; at higher shortening velocities, the peak power output declines. Which of the following factors can explain this observation?

Most of the increase in mean arterial blood pressure that occurs during dynamic (isotonic) incremental exercise is due to

The amount of force exerted during muscular contraction is dependent on the
