| catheter fitted outside or over a steel needle | over the needle catheter |
| catheters passed through the needle are | through the needle catheters used primarily in jugular veins |
| catheters with two to three separate lumina in one catheter and allow simultaneous infusions at a single catheter site | multi-lumen catheter |
| supplies needed for catheter placement are | catheter, flush, injection cap or T-set, suture, bandage material, clippers and antiseptic scrub with alcohol |
| common peripheral insertion sites are | cat-cephalic medial, dog-lateral saphenous |
| placement of a jugular catheter over peripheral catheters are | 1. allows for fluids with osmolality greater than 600 and CRI of drugs known to cause phlebitis. 2. enables measurement of central venous pressure. 3.frequent draw of blood samples. 4.necessary for total parenteral nutrition |
| the required distance for a jugular catheter insertion is | estimated by measuring the distance from the intended insertion site to the caudal edge of the triceps muscle |
| a dilator is used to | enlarge the insertion site of the catheter |
| signs of phlebitis may include | erythema, swelling, tenderness and apparent increase in skin temperature over the vein |
| thrombosis is characterized by | a vein that stands up without being held off and a thick cord like feeling to the vein |
| catheters not in use should be flushed | every 4 hours with 4U/ml heprinized saline |
