Week 1 & 2 IV infusion therapy Flashcards

1
Q

What are the 5 reasons people need IV infusion?

A
  1. can’t drink/eat - NPO
  2. cuz they’re N &V - replace fluid
  3. Diabetes insipidus - peeing it out like a B
  4. Blood loss - hypovolemic
  5. losing it through skin- burns- insensible losses

Q

Who is hypotonic fluid for and why?

A
  • dry mucous membranes (dry cells)
  • Hypertension

b/c it causes fluid to move out of the Vascular system and into the cells. Lowers BP and hydrates cells

Q

What IV fluid do we NOT give to infants or people with any head injury and why?

A

D5W (Dextrose in water)

can cause cerebral edema because the sugars get broken down in the body and then it becomes hypotonic. Fluid will be drawn out of the vascular system and into the interstital/intracellular spaces

Q

What are the 5 indications of isotonic 0.9% NS and why?

A
  1. shock - hypovolemia

Q

What solution is used for acute blood loss?

25
What is a risk with any D5 IV solution?
hyperglycemia
26
What are the main 4 risks of hypertonic fluids?
1. Fluid overload 2. Pulmonary edema 3. hyperglycemia 4. Iv sites phlebitis and infiltration
27
Which fluid is typically indicated for Post-op and why?
D5 .45NS Dextrose (calories) Rehydration of vascular system b/c fluid drawn in
28
Which 3 dx should caution be used with Hypertonic solutions and why?
1. DKA - already high BS 2. Cardiac patients - fluid overload/pulmonary edema (arythmias with D5LR) 3. Renal (kidney) issues - fluid overload & glucose excretion issues
29
What is the main risk of 0.9NS and why?
Fluid overload b/c you're just filling the vascular system
30
What are the 2 main risks of LR and why?
1. Fluid overload b/c you're filling the vascular system 2. Hyperkalemia b/c potassium in LR
31
Which solution causes vein irritation?
D5W
32
what are the dx that caution should be taken when giving 0.9 NS and why?
1. HTN, HF, Edema - fluid overload 2. Hypernatremia - b/c it has NaCl in it
33
what are the dx that should not have LR and why?
1. Liver disease - can't metabolize the lactate 2. cardiac patients - fluid overload + hyperkalemia
34
what are the dx that should not have D5W and why?
1. increased ICP (hypotonic in the body and can increase fluid in brain/body) 2. renal patients - edema 3. cardiac patients - edema
35
What are the risks with hypotonic fluids and why?
1. Hypotension - fluid out of vascular system and into cells 2. increase peripheral edema - fluid into extracellular spaces 3. increase ICP - fluid out of vascular system 4. hyponatremia - 5. IV site phlebitis- foreign object in skin
36
what dx should caution be used with hypotonic fluids?
1. stroke - fluid shift 2. head trauma - fluid shifts 3. increased ICP - fluid shifts 4. severe burns - fluid shifts out of the skin (they already lose water through burns)
37
How often do we change primary infusion tubing?
every 96 hours ( 4 days)
38
how often do we change IV bag?
every 24 hours
39
What are 2 benefits to PIV saline locks?
1. patient more mobile 2. intermittent infusions
40
how often do we change needleless connectors?
1. every 7 days 2. contaminated or residual blood is in the device after flushing
41
how many cc of NS do we use to flush IV ?
2-3cc of NS
42
Do we aspirate for blood before or after initial flush?
After. Flush first, aspirate second.
43
if no blood return, how many cc's of NS while watching for swelling, pain, patency?
min 3cc - max 10 cc
44
if NS lock is not in use, how often do we flush?
Q 24 hrs or D/C if not required anymore
45
What are 3 causes of Phlebitis?
1. Mechanical 2. Chemical 3. Bacterial
46
How often do we assess running IV's for inpatient and nursing facilities?
at least every 4 hours
47
how often do we assess running IV's for patients who are critically ill/sedated or have cognitive deficits?
Q1-2 hours b/c they can't tell us how the IV is going
48
How often do we assess running IV's for neonatal/pediatric patients?
Q1h
49
How often do we assess running IV's for patients receiving infusions of vesicant medications?
more often
50
Can prefilled syrnges be used for dilution and reconstitution? Why or why not?
no 1. because the label says NS so any additional medication makes the label wrong 2. volume is "approximate" and not good for reconstitution
51
When do we do first check for mini bag?
When we gather supplies
52
When do we do second check for mini bag?
just before dilution (just before mini bag)
53
When do we do our third check for mini bag?
patient bedside
54
Do we use the MAR or Doctor's order for mini bag and why?
MAR because the order doesn't have the right "time"
55
how often must any IV tubing be changed?
96 hours or 4 days
56
Any tubing (primary or secondary) that is disconnected from the patient must be changed how often?
q 24 hrs
57
The 96 hour tubing rule does not apply to which solutions/liquids?
lipids TNA propofol blood/blood products
58
Can we use the same tubing for a newly inserted central line that we used for peripheral?
no. must get new tubing
59
How many mL must we use to flush the line after piggy back medication is done?
15 mL - set pump
