Study Notes
Respiratory Rates and Medication Administration
- Adult normal respiratory rate: 12-20 breaths per minute.
- Parenteral route for medication: Intramuscular injections.
Contrast-Enhanced CT Exam Procedures
- For patients with a history of allergic reactions to iodinated contrast, premedication with steroids and antihistamines is necessary.
- Signs of shock in patients include tachycardia, rapid shallow breathing, and cyanosis.
Infection Control and IV Procedures
- Surgical asepsis is mandatory at IV injection sites for iodinated contrast media.
- Common IV injection sites include cephalic, antecubital, and basilic veins.
Technical Factors and Patient Safety
- Patient dose is directly affected by milliampere-seconds (mAs).
- Assess renal function, allergic history, and cardiac history prior to iodinated contrast material administration.
Biological Implications of Iodinated Contrast Media
- Osmolality indicates the number of ions formed when a substance dissociates in solution.
- Laboratory values for renal function evaluation include blood urea nitrogen (BUN) and creatinine.
Healthcare-Associated Infections and Radiation Safety
- Nosocomial infections are acquired during a healthcare institution stay.
- CT patients require shielding due to the rotational nature of the x-ray tube.
Contrast Injection Techniques
- Angiocatheters are preferred for intravenous contrast material injections using a power injector.
- Non-ionic contrast materials do not dissociate into charged particles in solution.
Patient Communication and Preparation
- Clear explanations of the CT procedure ensure compliance with breathing instructions, minimize misregistration, and reduce patient anxiety.
Needle Specifications and Contraindications
- Needle lumen diameter is described in gauge units.
- Direct contraindications for iodinated contrast: prior life-threatening reaction and multiple myeloma.
Patient Identification Safety Measures
- Best verification method for patient identity is checking the patient's wrist identification band.
