Venipuncture, ABG, IV Flashcards
Venipuncture Can be used as a therapeutic modality for which disease
Polycythemia
Is blood draw CI in the same side as a mastectomy?
yes
MC vein used to blood draw
median cubital vein
Where do you Apply a tourniquet
5-10 cm above the chosen site
Insert the needle, with the bevel facing up, at an angle of
15-30°
Light blue tube top
3.2% Sodium citrate, PREVENTS CLOTTING, “Coagulation” - DDIMER
Red/ gold Tube top
CLOT ACTIVATOR
Drk green tube top
Sodium/ Lithium, Prevents clotting by inhibiting thrombin
Lavander/pink tube top
Potassium EDTA, prevents clotting
When do you preform Blood Cultures
infection of the blood(bacteremia or septicemia) is suspected
Why do you do ABGs
critically ill patients, to determine gas exchange levels in the blood related to respiratory, metabolic, and renal function - acid/ base balance. radial artery after Allens sign
What is ABGs Only reliable determination of ventilation - O2 or CO2
Co2
Only way of accurately determining the alveolar-arterial oxygen gradient
(A-a Gradient) ABGs
Errors in ABG analysis can occur with:
Excess air bubbles or incomplete removal of air bubbles – falsely elevated pO2
Excess heparin in the syringe – false low values of pCO2
Delays in placing the sample on ice
Intradermal Injection
TB PPD
Subqutaneous Injection
For drugs requiring slow absorption and long duration of action Insulin Hormones Vaccines Heparin/Low Molecular Weight Heparin
IM injections
Drugs not easily absorbed orally Intermediate rate of onset and duration of action preferred When parenteral delivery necessary Antibiotics Narcotics/ Pain meds Hormones Vaccines
Purpose of Venous Catherization (IV)
Fluid replacement
Delivery of medications
Blood sampling (see venipuncture)
Interassoues (IO) lines
Process of injecting directly into the marrow of a bone to provide a non-collapsible entry point
Used to provide fluids and medication when IV access is not available or not feasible
IO Superior Method
Placement of IO
2cm distal to tibial tuberosity - STERILE PROCEDURE
