IV CERTIFICATION COMPREHENSIVE EXAM 2025
QUESTIONS WITH ANSWERS GUARANTEE A+
✔✔best vein for irritating medications and blood transfusions - ✔✔cephalic vein
✔✔accessory cephalic vein - ✔✔joins cephalic vein below the elbow
✔✔over the needle catheter size for cephalic vein - ✔✔18G-22G
✔✔basilic vein - ✔✔runs along ulnar aspect of the forearm
✔✔what arteries run under basilic vein? - ✔✔brachial and radial
✔✔what is the basilic vein at risk for? - ✔✔hematoma formation
✔✔what must nurse due post removal of IV at basilic vein? - ✔✔apply pressure to the
site and do not flex elbow to stop bleeding
✔✔what over the needle catheter size can be used for basilic vein? - ✔✔18G-22G
✔✔median cubital vein - ✔✔loacted just below the elbow bend and connects cephalic
and basilic veins
✔✔over the need catheter size for median cubital vein - ✔✔16G-18G
✔✔median ante-brachial vein - ✔✔vental surface of the forearm, not always easy to
visualize
✔✔what vein infiltrates easilt? - ✔✔median ante-brachial vein
✔✔over the needle catheter size for median ante-brachial vein - ✔✔18G-22G
✔✔superficial/cutaneous veins - ✔✔-used for IV insertion
-unite with deep veins in LE
-danger of thrombosis or blood clot
-could result in PE formation
✔✔deep veins - ✔✔-enclosed in the same sheath as arteries
-AV anastomosis may occur from past injury of vein and nearby artery
-recognition of AV fistula can prevent pain, complication, and loss of time resulting from
repeated unsuccessful venipuncture attempts
✔✔tonicity - ✔✔concentration of a substance dissolved in water
, ✔✔isotonic solution - ✔✔-same osmolality as normal body fluid
-equal pressure on both sides of semipermeable membrane
✔✔hypotonic solution - ✔✔-low osmolality compared to normal body fluid
-pulls fluid into cells causing them to swell and burst
✔✔hypertonic solution - ✔✔-greater osmolality than normal body fluid
-draws fluid out of cells and into plasma, cell shrinks
✔✔examples of isotonic solutions - ✔✔1)Lactaid Ringers 2) NS (0.9% NaCl) 3) 5%
Dextrose

✔✔solution for dehyration - ✔✔hypotonic solution
-D5W, D2.5W
✔✔solution for fluid maintenance - ✔✔D5W, D5 1/3NS
✔✔solution for fluid volume replacement - ✔✔D5 1/2 NS
✔✔solution for diuretic effect - ✔✔D10W-hypertonic solution
✔✔what is 0.9% NS used for? - ✔✔ECF replacement
isotonic dehydration
metabolic alkalosis
blood transfusion
✔✔what does tonicity affect? - ✔✔IV fluid infusion rate and IV site
✔✔osmosis - ✔✔Diffusion of water through a selectively permeable membrane from an
area of lesser solute concentration to an area of greater solute concentration
✔✔cation - ✔✔A positively charged ion
✔✔anion - ✔✔A negatively charged ion
✔✔solutes of ECF - ✔✔sodium, potassium, calcium
✔✔solutes of ICF - ✔✔potassium, magnesium, sodium
