Question

20 fill in the blank 1 point what breathing instructions should be given to the patient during abdominal imaging? type your answer... 21 fill in the blank 1 point with reference to radiation protection, what is the advantage of the pa projection over the ap projection? type your answer... 22 essay 1 point why is a left lateral decubitus position preferred over the right lateral decubitus position when the patient is unable to stand?

Explanation:

For question 20, holding breath during abdominal imaging reduces motion - artifacts. For question 21, in PA projection, the x - ray beam passes through less sensitive organs first compared to AP projection, reducing radiation exposure to sensitive organs. For question 22, the left lateral decubitus position is preferred as it allows free movement of gas in the abdomen and helps in detecting air - fluid levels better, and also reduces the superimposition of the liver on the abdominal cavity.

Answer:

1. Hold your breath.
2. The x - ray beam passes through less sensitive organs first, reducing radiation exposure to sensitive organs.
3. Allows free movement of gas in the abdomen, helps in detecting air - fluid levels better and reduces liver superimposition on the abdominal cavity.
