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.
