Cardiogenic

300

The QRS complex on a typical ECG represents

depolarization of ventricular muscle.

A common neonatal chest disorder requiring portable radiography 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 degree of aseptic techniques.
2. use lead protection when possible, and sterilize after each use.
3. surgically scrub your hands to replace gloves in order to position the neonate with better precision.
4. wrap all items that may have the potential 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.

1. Use a standard bedpan.
2. Provide for the patient’s privacy and locate a fracture bedpan.
3. Be sure to wear gloves and wash your hands.
4. If the bedpan is metallic, run it under warm water for patient comfort and discard in a recycling bin.
5. You and an assistant should assist the patient with movement onto the bedpan.
6. Return the patient to the nursing floor for cleanup and patient hygiene.

When performing radiologic examinations on patients with chest tubes,

the chest drainage system has three compartments: collection chamber, water seal chamber, and suction control chamber

the exterior chamber of the assembly must remain higher than the patient’s chest level to prevent retrograde flow.

check for the color of the drainage and report any pale amber color indicating serous fluid.
