|
|
a nurse should only try __ times to do a successful stick
|
2
|
|
accurate charting of iv is?
|
date time, what vein, gague style of needle, infusate administere
|
|
how long can you leave in an iv done by ems,
|
change asap and before 48hrs
|
|
iv caths should be changed every
|
3 days
|
|
hanging bag of lipid containing solutions (3-1)must be infused within how many hrs
|
24
|
|
hanging back of lipid emulsions alone must be done in
|
12hrs
|
|
blood must be infused within
|
4hrs

|
|
what is homeostasis
|
the physiologic term for the process that contributes to a state of internal constancy
|
|
primary chemical component of the human body
|
water
|
|
what is osmolarity
|
osmotic pull or pressure exerted by all particles per unit of solution influenced by qwuanity of dissolved particles that exer an osmotic pull
|
|
you'd give hopytonic fluids with
|
dialysis or DKA
|
|
would not give hypotonic fluids with pts that are
|
edemic
|
|
fluid stays within the intravascular space.no fluid flowing into or out of the intravascular spaces
|
isotonic
|
|
lower number of molecules then serum so fluid shifts from the intravascular spaces to the interstitial spaces
|
hypotonic
|
|
this fluid can cause ICP and cardivascular collapse r/t the shift from the is to the cells.
|
hypotonic
|
|
.45 NaCl and 2.5 dextrose are examples of
|
hypotonic
|
|
has less osmolarity then serum. water is then pulled from the vascular compartment
|
hypotonic
|
|
this has a higher osmolarity then serum. pulls fluids and electrolyts from the is into the intravascular compartment
|
hypertonic
|
|
d5%, .45Nacl, d5%LR, blood and slbumin
|
hypertonic
|
|
fluid shifts from the interstitial spaces into the intravascualar spaces
|
hypertonic
|
|
crystalloids are
|
effective volume expanders
|
|
crystaloids are ideal for pts who
|
need fluid replacement.
|
|
when using an isotonic crystalloid to control blood pressure from blood loss,what is the ratio
|
3ml of crystolloid to every 1ml of blood loss
|
|
watch for pulmonary edema with what fluid replacements
|
crystalloid
|
|
examples of crystalloids are
|
LR, NS
|
|
initial crystalloid replacement should not exceed how much before whole blood is instituted
|
3 liters.
|
|
colloids contain what that are too large to pass out of the capillary membrain and so they remail in the vascular compartment
|
molecules, usually proteins
