Study Notes
Airway Management
- Open the airway by tilting the head back and lifting the chin.
- Use the jaw-thrust method if spinal injury is suspected, avoiding neck movement.
- Listen for breathing sounds and observe chest movements.
- If breathing is absent, pinch the nose and deliver two mouth-to-mouth breaths.
- Implement the Heimlich maneuver if chest rise doesn’t occur after breaths.
- Check for pulse in the carotid artery; if absent, perform chest compressions.
- Compression rates: 80-100/min for adults; at least 100/min for infants.
Patient Transfer Techniques
- To minimize back strain when moving patients, always pull rather than push.
- Do not bend at the waist while pulling; utilize your biceps for strength.
- Keep the patient as close as possible before lifting.
Contrast Media and Safety
- Barium sulfate is the least toxic contrast medium due to its inert nature.
- Iodinated contrast media are absorbed by the body, unlike barium sulfate.
- Normal blood urea nitrogen (BUN) levels are 8 to 25 mg/100 mL; elevated levels signal possible renal function issues.
- Warming iodinated contrast media before use decreases viscosity, facilitating injection.
Infection Control and Hand Hygiene
- Handwashing is crucial after each patient examination to maintain aseptic techniques.
- Do not bend or ignore any skin cracks or abrasions; proper care is necessary for healing.
- In aseptic practice, a thorough hand cleaning process is essential.
Emergency Response
- Anaphylaxis can result from exposure to drugs, vaccines, or allergens, leading to life-threatening reactions.
- Myocardial Infarction (MI) occurs due to blockage in coronary arteries, highlighting the need for quick identification and treatment.
Patient Care Responsibilities
- When patient complaints differ from the examination requisition, radiographers should verify with the referring physician to avoid unnecessary radiation exposure.
- Ensuring the correct examination is performed is vital for patient safety.
Isolation Procedures
- In contact isolation, the radiographer must wear gown, gloves, mask, and cap.
- Clean the mobile x-ray unit after exiting a patient's isolation room to maintain hygiene, not before entering.
Post-Examination Instructions
- After a barium enema (BE), instruct patients to increase fluid and fiber intake.
- Changes in stool color are to be expected until all barium is expelled.
Heimlich Maneuver Technique
- The Heimlich maneuver is specifically for people who are choking.
- Confirm airway obstruction by checking if the individual can speak or cough.
- For adults: Stand behind the victim, perform abdominal thrusts by placing a fist midway between navel and xiphoid process.
- For infants: Use back blows and chest thrusts to dislodge objects safely.
