A common neonatal chest disorder requiring portable radiography is in the neonatal unit is transient tachypnea of the newborn (TTN). Radiographs are taken to visualize the chest for respiratory distress, and in doing so, the imaging professional must.... 1. Use the highest Desiree of aseptic techniques 2. Use lead protection when possible, and sterilize after each use 3. Wash hands only after the procedure is complete 4. Wrap all items that may have the potentiometer of coming in contact with the newborn 5. Use contact or shadow shielding for patient protection 6. Treat the procedure as a sterile procedure similar to surgery

Steps to sterile draping

1. Place package on center of surface and top flap of the wrapper set to open away from person opening package2.pinch the first flap on the outside of the wrapper between the thumb and index finger by reaching around and NOT over the package3.use the right hand to open the right flap and left hand to open the left flap4. Grasping the turned-down corner, pull the fourth and final flap.Note; the outer 1" edge of the sterile margin is not sterile Continued.... 1. Hold package in one hand with the top flap opening away from the person opening the package 2.pull top flap well back and hold it away from both the contents of the package and the sterile field. Using the free hand to hold the flap against the wrist of the hand holding the package is an effective technique3. Drop the contents gently onto the sterile field from approximately 6" above the field at a slight angle

Packages are considered sterile if they meet the following criteria:

1. The expiration date has not been exceeded. 2. The sterility indicators have changed to a predetermined color. 3. The package is clean and dry.

D

When performing radiologic examinations on patients with chest tubes, A. Remember that the chest drainage system has 3 compartments: collection chamber, water seal chamber, and suction control chamber B. Check for the color of the drainage and report any dark red color C.
