Study Notes
Hypodermic Needles
- "Gauge" indicates the lumen size of a hypodermic needle.
Catheters
- Hickman and Groshong catheters provide central vascular access.
- Levin catheters are specifically used for nasogastric (NG) tubes.
Blood Pressure
- Hypotension is defined as a systolic blood pressure of less than 90 mmHg.
Medical Conditions
- Ketoacidosis signifies acute hyperglycemia, a serious metabolic condition.
Radiography and Physics
- Minimum electron energy to create a characteristic photon in a K-shell tungsten atom is 69.5 keV.
- In a right anterior oblique esophogram (RAO), the patient is rotated 35-40 degrees from a prone position.
Safety Symbols
- The biohazard symbol indicates potential biological dangers in a given environment.
Infection Control
- Patients with pertussis, whooping cough, or influenza are placed under droplet precautions.
Digital Imaging
- The smallest pixel size corresponds to the matrix size of 2048 x 2048.
- The lateral decubitus chest radiograph is most effective for demonstrating pleural effusion.
AEC and X-ray Techniques
- For a hip fracture x-ray taken at 52 inches SID with 80 mAs, the new mAs at 40 inches will be 47 mAs using the direct square law.
- A photometer is utilized to evaluate the luminance response of digital display monitors.
Tuberculosis Precautions
- Healthcare providers should follow airborne precautions for active pulmonary tuberculosis cases.
Renal Anatomy
- The renal hilum contains the renal pelvis, a critical structure for kidney function.
Technique Chart Storage
- The technique chart for anatomically programmed technique systems is located in the microprocessor of the control unit.
Radiation Dose Calculation
- At a distance of 72 inches, a dose of 125 microgray increases to 405 microgray at 40 inches, calculated using the inverse square law.
Radiation Characteristics
- High linear energy transfer (LET) radiation leads to rapid energy deposition, concentrated tissue damage, and increased biologic harm.
HIPAA Training
- Failing to include HIPAA law training is a violation only if the employee has access to protected health information.
Polycystic Kidney Disease on Radiographs
- Polycystic kidney disease appears as multiple radiolucencies in the renal cortex due to cystic lesions not filling with contrast.
Exposure Technique Systems
- The fixed kVp system applies the rule to double or halve mAs for every 5 centimeters of object thickness.
Digital Imaging Components
- An electronic signal is produced by a digital imaging receptor (IR).
Normal Pulse Rate
- The normal pulse rate in adults ranges from 60 to 100 beats per minute (BPM).
Spinal Anatomy
- The eye of the Scottie dog on oblique lumbar spine radiographs indicates specific vertebral anatomy, crucial in diagnosing conditions like spondylolysis.
