| bacteremia | bacteria in blood |
| septicemia | "sepsis", inflammatory immune response due to bacteria in blood, usually fatal |
| septicemia signs | fever, high heart rate, low bp, rapid breathing>>shock |
| Important differences vs. venipuncture | greater detail in patient procedure instructions: more blood, 2 venip, "tubes" diff |
| Interfering factors: antibiotics | collect before antibiotics. resin beads (charcoal) neutralize by mixing |
| Blood culture ? in order of draw to | first. avoid needle contamination |
| fill ? bottle 1st b/c | anaerobic. bacteria>>exposure to air>>die>>false neg result |
| Best practice to ? from indwelling IV catheter | NOT draw |
| ? palpate sterile site | do NOT repalpate sterile site |
| If must repalpate | wear sterile gloves, above/below puncture site |
| iodine tincture swab | allergic chlorhex or <2 mos old |
| chlorprep contains | chlorhexidine gluconate and alc |
| blood culture draw - ask patient before procedure | allergies to antiseptics? |
| 70% alc prep = ? sec | 60 sec using circles (rids surface dirt) |
| chlorhexidine gluconate = ? sec | 30 sec using circles |
| chloraprep = ? sec | 30 sec scrubbing back/forth |
| airdry = ? sec | 60 sec |
| no chloraprep for | <2 mos old |
| collection methods | syringe, butterfly, evac tube holder (SPS only) |
| sterile cap removed>> | cleanse top with 70% alc |

| ABG from ? artery | radial first |
| ABG provides useful info about | respiratory status and acid-base bal |
| Therapeutic drug monitoring (TDM) used to monitor | serum concentration of certain drugs |
| TDM requires coordination | timing important |
| trough vs. peak | lowest concentration of drug in patient's serum vs. highest |
| genetic molecular test in ? tube | Lavender. |
| cytogenetic test in ? tube | green: sodium heparin |
| Genetic material is only viable for ? | 6-24 hours |
| fistula | artificial shunt, vein + artery fused through surgery for dialysis, do not collect! strong "buzzing" pulse |
| cannula | tubular instrument to access vein for dialysis |
| autologous transfusion | blood donation before surgery>>given to themselves, safest blood is your own, eliminates the possibility of antibodies forming when transfused |
