1 Wipe away the first drop of blood with a piece of clean, dry cotton gauze. 2  Since newborns do not often bleed immediately, use gentle pressure to produce a rounded drop of blood. 3  Do not use excessive pressure because the blood may become diluted with tissue fluid. 4  Fill the required microtainer(s) as needed.
You'll likely see labels like THHN or THWN written on the wire. For example, THHN wire stands for thermoplastic high heat-resistant nylon coated wire. THWN stands for thermoplastic heat- and moisture-resistant nylon coated wire. As you can see, these wires are built to take on many different conditions.
Flexible sheathed cable is easier to run through holes in studs than metallic sheathed cable, it is also cheaper. Romex cable is labeled as NM-B, which means the sheathing is non-metallic cable; other brands use code NMC. The NM designation is used to distinguish it from metallic sheathed (BX or AC) cable.Another designation, UF, indicates the cable is rated for direct burial in the ground (although local codes may not permit that use). A rating of 14/3 refers to the gauge of the wire and how many conductors are in the cable.In this case, the wire gauge is fourteen (lower numbers mean larger wires) and the three indicates that there are three conductor wires in addition to a non-insulated ground wire.So, in the image above of 12/2 sheathed cable, there are two twelve gauge insulated conductors plus a bare twelve gauge ground wire.lexible sheathed cable is easier to run through holes in studs than metallic sheathed cable, it is also cheaper.
