Cardio Assess Unit 3
SPC Cardiopulmonary Assessment Unit 3 Exam 2
Question | Answer |
---|---|
Describe Posteroanterior Radiograph (PA) | STANDARD, patient is standing, x-ray beam through the back, film against anterior chest |
Describe Anteroposterior Radiograph (AP) | POTABLE, patient is lying in bed, x-ray beam through the anterior chest, film against the back |
Describe Lateral Radiograph | Patient turns sideways, film placed along R or L lateral chest wall, used to asses Lower Lobe Lesions |
Describe Lateral Decubitus Radiograph | Patient lies w/ film against affected side, used to assess pleural effusion |
Describe Apical Lordotic Radiograph | Film placed along patients upper back, x-ray placed @45degree caudal angle from the lower anterior chest is shot, used to asses middle and upper lobe lesions |
Radiation safety for RT's consist of what? | 1. At least 6ft away behind something 2. Bagging through scans 3. Protect neck, pads, & knees 4. Watch out for floroscopes |
Many radiograph techniques were replaced by what? | CT scans |
What color is air on a CXR? | Black |
What are the 4 desities on a CXR? | Radiolucent, Black, White, |
What does radiolucent mean? | Transparent to X-Rays, Black, air |
What does radiopaque mean? | Non-Transparent to X-Rays, White, dense objects |
What would show up black? | AIR: Parenchyma, Pneumothorax, Bullae, Pneumatoceles |
What would show up light gray? | FLUID: Blood vessels, Fissure fluid, Pleural fluid |
What would show up white? | DENSE Objects: Fat, Heart, Breast, Adipose, Bone, Clavicles, Ribs |
