    Study Notes

    EKG and Dysrhythmias

    • Dysrhythmias evaluation includes rate, artifact, and complexes on the ECG tracing.
    • QRS duration measures ventricular depolarization time.
    • The P wave shape analysis reveals if atrial depolarization proceeded normally.
    • Normal PR interval ranges from 0.12 to 0.20 seconds.
    • Healthy QRS complex duration is less than 0.12 seconds.
    • Normal sinus rhythm occurs at a rate of 60 to 100 bpm.
    • Sinus bradycardia features a rate less than 60 bpm, possibly requiring medication or a pacemaker.
    • The Einthoven triangle consists of leads: right arm, left arm, and left leg.
    • V1 lead is placed at the fourth intercostal space, left sternal border.
    • Lead V3 requires prior placement of leads V2 and V4.
    • Irregular rhythms are calculated using the 6-second method.

    Phlebotomy

    • Lavender-stoppered tubes contain ethylenediaminetetraacetic acid (EDTA) as an anticoagulant.
    • For platelet function tests, a sodium citrate tube is used.
    • A discard tube for coagulation testing should ideally be red non-additive.
    • Gray-stoppered tubes feature sodium fluoride as anticoagulant and anti-glycolytic agent.
    • Light green tubes contain lithium heparin with a thixotropic gel.
    • For an immediate prothrombin time test, a light blue tube is appropriate.
    • When applying a tourniquet, it should be positioned 3-4 inches above the puncture site.
    • Fasting specimen is particularly required for lipid panel tests.
    • To ease a child's anxiety during a procedure, talking directly to them is suggested.

    Blood Collection Techniques

    • Collecting blood from an infant’s heel for bilirubin tests requires a microcollection container, ideally Amber SST.
    • Thixotropic separator gel rises to the top when centrifuged.
    • When probing for a vein leads to pain or injury, it qualifies as a direct cause of patient injury.
