Question

19 essay 1 point how should the patients hands be positioned on a pa projection of the chest and why? 20 essay 1 point what are the breathing instructions given for chest radiography and why?

Explanation:

For a PA (postero - anterior) projection of the chest, the patient's hands are typically positioned by having the patient grasp the handles of the upright Bucky or place their hands on their hips with elbows flexed and rotated forward. This is done to move the scapulae laterally away from the lung fields, reducing superimposition and allowing for a clearer visualization of the pulmonary structures. For chest radiography, the common breathing instruction is to take a deep breath and hold it. This expands the lungs fully, separating the lung lobes and making it easier to detect any abnormalities such as infiltrates, masses, or atelectasis.

Answer:

For the first question: The patient can grasp the handles of the upright Bucky or place hands on hips with elbows flexed and rotated forward to move scapulae away from lung fields.
For the second question: Take a deep breath and hold it to fully expand lungs for better visualization of abnormalities.
