GXMO Patient Care and Positioning 4

Question 1

For a lateral projection of the lumbar spine, the patient's hips and knees are flexed primarily to:

Accepted Answer

Reduce the lordotic curve and bring the spine parallel to the IR

Question 2

What is the primary purpose of asking a patient to suspend respiration on expiration during an abdominal radiograph?

Accepted Answer

To move the diaphragm superiorly and maximize visualization of abdominal contents

Answer

Expiration raises the diaphragm, pushing abdominal organs inferiorly and allowing more complete visualization of the abdominal cavity.

Keep the collection bag below bladder level and handle tubing carefully to avoid tension

Answer

The catheter bag must remain below bladder level to allow gravity drainage, and the tubing must not be pulled or kinked during positioning.
