AVA CERTIFICATION EXAM: TYPES OF VASCULAR ACCESS DEVICES 2023

AVA CERTIFICATION EXAM: TYPES OF VASCULAR ACCESS DEVICES Peripheral Intravenous Catheter dwell time? - 72-96 hours Peripheral Intravenous Catheter infusate parameters are? - non-vesicant non-irritant pH 5 to 9, osmolality <600 Does Peripheral Intravenous Catheters require sterile technique for placement? - PIVs can be placed using clean gloves; does not require sterile technique. Midline Catheters are how long? - approximately 20 cm Midline Catheters terminate where? - in the upper arm at the level of the axilla Midline Catheters may be used for how long? - 2-4 weeks Midlines are intended for infusions of what type? - non-irritating, non-vesicant drugs with pH between 5-9 and osmolality of less than 600. Non-tunneled Percutaneous Catheter may have up to how many leumens? - 1 to four Non-tunneled Percutaneous Catheter terminates in the - Superior Vena Cava or near the Cavoatrial junction Non-tunneled Percutaneous Catheters are intended for what types of patients? - critical care, major trauma, patients requiring short-term central venous access for complex intravenous therapies, inpatient settings only Non-tunneled Percutaneous Catheter dwell time? - Up to 7 days. Examples of Non-tunneled Percutaneous Catheters? - Subclavian, percutaneous, acute-care, or short-term catheters. Inserted into the internal jugular or subclavian vein. Occasionally, the femoral vein is used with the tip resting in the INFERIOR VENA CAVA. Non-tunneled Percutaneous Catheter infusates? - There are no restrictions. Appropriate for multiple cardioactive and inotropic drugs, TPN, blood products, antibiotics, and sedating medications that are delivered together. Non-tunneled Percutaneous Catheter veins that are accessed? - Internal jugular, external jugular, subclavian, axillary. Femoral vein should be avoided except in emergent situations; it should be removed as soon as alternate reliable access is established. Why does non-tunneled Percutaneous Catheter require x-ray? - To determine catheter tip position and to rule out pneumothorax. Percutaneous Catheter can be used for hemodynamic motoring which includes what? - Central Venous Pressure Central venous pressure reflects the amount of blood returning to the heart and what? - the ability of the heart to pump the blood into the arterial system. What is normal range for CENTRAL VENOUS PRESSURE? - 2-8 cm H20 manometer 2-6 mmHg transducer Insertion method of percutaneous catheter is performing percutaneous venipuncture in what locations or situations? - at beside or emergency setting without sedation. Indications for placement of percutaneous catheters? - intravenous therapy, blood sampling, and central venous pressure monitoring. Why is the risk of percutaneous catheter infection greater? - Protrudes externally and there is no subcutaneous tunneling. Why is the risk of pneumothorax greater with a percutaneous catheter? - because the vein is punctured directly above the lung. How is the percutaneous catheter inserted as a subclavian? - Entrance point is below the clavicle, into the subclavian vein, travels down not up the jugular, to the superior vena cava or near the cavoatrial junction Peripherally Inserted Central Catheter dwell time? - 5-7 days or more Maximum dwell time is unknown.
