Question

what is the optimal respiration phase for a pa or lateral chest radiograph?
second breath, full inspiration
second breath, full expiration
first breath, full expiration
first breath, full inspiration
(incorrect response not displayed)
5 0.5/1 point
which two of the following will be observed on a supine ap chest radiograph? (select all that apply.)
clavicles projected higher and horizontal
all 12 ribs are seen.
lung fields appear longer.
lung fields appear shorter.
(incorrect response not displayed)

Explanation:

For the first question, the optimal respiration phase for a PA or lateral chest radiograph is the second breath, full inspiration. This allows for better visualization of the lungs and thoracic structures. In a supine AP chest radiograph, the clavicles are projected higher and horizontal due to the patient's position, and the lung fields appear shorter because of the lack of full - lung expansion compared to upright positions.

Answer:

1. Second breath, full inspiration
2. Clavicles projected higher and horizontal

Lung fields appear shorter
