35
treatment of infiltration
warm compress for hypotonic solution, cool compress for isotonic or hypertonic solution, elevate extremity, remove catheter and restart away from site, document infiltration and treatment (might need to call provider)
36
extravasation
worst complication of IV; leakage of a vesicant into surrounding tissue causing damage to vein and tissue
37
vesicant
any medication that can cause blistering, severe tissue injury, or necrosis
38
examples of vesicants
chemotherapeutic agents, catecholamines, dopamine, levophed, epinephrine, norepinephrine, gentamycin, mannitol
39
infiltration of any vesicant is considered...
extravasation
40
treatment of extravasation
stop the infusion, remove IV, clean site, notify physician, do no restart
41
sepsis
life threatening complication of an infection that occurs when chemicals are released into blood stream to fight infection but trigger inflammatory throughout entire body; symptoms include fever, diff. breathing, low BP, fast HR, mental confusion
42
evaluating patient with PIV
pt IV remains patent, p does not experience complications, and if complications occur then recognize early
43
central lines placed into...
opening of the superior vena cava into the right atrium
44
types of peripherally inserted central line IV catheters
picc- long term use, long line, ends up in central venous system; midline catheter- not entered into central venous system, used long term but not as long as a picc
45
j-line IV
used in emergency situations, peripherally inserted into a large vein
46
tunneled vs non-tunneled
non-tunneled is not used in long term scenarios and usually sutured in place; tunneled are used more long term and tube is passed under the skin
47
implanted port
aka port-a-cath; another central access system; used for long term therapy and for those with chronic illness; allows for freedom due to no long wires hanging; not good to use if pt needs daily infusions; CF patients commonly have ports
48
huber needle
needle used to inject into implanted ports
49
CVAD considerations
typically inserted under ultrasound or radiography; require xray confirmation following insertion and prior to using if done at bedside
50
criteria for deciding which access device to use
emergent vs. non-emergent situations, type and length of treatment, quality of life, the medication to be administered, least risk of complications, pt/family ability and preference
51
complications associated with CVAD
CLABSI, air embolism, pneumothorax from insertion, migration, thrombosis (blood clots)
52
nursing assessment for CVAD
integrity of dressing, sutures intact?, s/s of infection?, tenderness upon palpation?, measure exposed catheter length, patentcy? (flushing well)
53
flushing a CVAD
use 10mL or larger to flush entire line, know your agency policies, central lines should have brisk blood return, infusion/IV site to be checked atleast every hour or more
54
bio-patch
goes around insertion of catheter into skin and is underneath dressing; infused with chlorhexidine, can be sutured in, change when you change dressing, place within 24 hours of IV placement
55
blood transfusions pre-assessment
vitals, baseline information, done immediately before infusion
56
blood transfusion requirements
pre-assessment, patient identification (2 identifiers), equipment
57
blood transfusion equipment
y-set filtered tubing (prevent clots and filter particles), normal saline
58
nursing care with blood transufsions
3 S's: stay with pt for first 5-15 minutes to observe for signs of reaction, start transfusion slowly for first 15 minutes (2mL/minute), stop blood transfusion if uspect reaction
59
considerations for blood transfusion
20 gauge PIV for adult (smaller causes destruction of RBC), return blood if not been used within 30 minutes of arrival from blood bank, unit of blood must be administered within 4 hours (must discontinue transfusion once past 4 hours)
60
vital sign monitoring for transfusion
q15min x 3, q30min x 2, q1hr until complete
61
s/s of transfusion allergic rxn
hives, itching, anaphylaxis
62
nursing intervention for transfusion allergic rxn
STOP transfusion immediately, keep vein open with N.S., notify provider immediately, admin antihistamine parenterally as needed
63
s/s of febrile rxn to blood transfusion
fever, chills, malaise, headache
64
nursing intervention for febrile rxn to blood transfusion
STOP transfusion immediately, keep vein open with N.S., notify provider, treat symptoms
65
s/s of hemolytic transfusion rxn to blood transfusion
immediate onset of facial flushing, fever, chills, headache, low back pain, shock
66
Nursing interventions for hemolytic rxn to blood transfusion
STOP transfusion immediately, keep vein open with N.S., notify primary care provider immediately, obtain blood sample from site, obtain first voided urine, treat shock if present, send unit of blood/tubing/filter back to lab, draw blood for serological testing and send urine to lab
67
s/s of circulatory overload from blood transfusion
dyspnea, dry cough, pulmonary edema
68
nursing interventions for circulatory overload from blood transfusion
Stop or slow infusion, monitor vital signs, notify primary care provider, place in upright position with feet dependent
69
s/s of bacterial rxn from blood transfusions (bacteria present in blood)
fever, HTN, dry flushed skin, abdominal pain
70
nursing intervention for bacterial rxn from blood transfusion
STOP infusion immediately, obtain culture of pt blood and return blood bag to lab, monitor vitals, notify primary care provider, administer antibiotic as ordered
71
if any signs of infusion rxn are present
STOP the transfusion
72
3 types of chest tubes
dry suction with wet seal, wet suction with wet seal, dry suction with dry seal
73
reason for inserting chest tube
collapsed lung, pneumothorax, hemothorax, tension pneumothorax
74
nursing care with chest tube
resp assessment- monitor RR, lung sounds, O2 sat.; monitor/record type, color, and amount of drainage; vasoline gauze/occlusive dressing over insertion; all connections secured and taped; tubing free of kinks; monitor for s/s of infection; semi-fowlers position; cough, turn, deep breathing q2hours; incentive spirometer and chest splinting; chest drainage system needs to be below chest tube level for gravity drainage
75
continue checking _____ at bedside with chest tube
water seal chamber is "tidaling", suction chamber is "bubbling" if it is to suction, suction set to 20cm and water seal at 2cm
75
necessities to keep at bedside with chest tube
1 vaseline gause, 1 occlusive dressing, new drainage system, sterile water
76
oropharyngeal airway
airway adjunct to keep airway open and keep tongue from obstruction; insert upside down until resistance is met and then flip; should sit at teeth; measure from corner of mouth to angle of jaw
77
nasopharyngeal airway
airway adjunct used to keep airway open and free from obstruction; measure from tip of nose to angle of jaw; use lube prior to inserting; bevel towards septum when inserting; contraindicated in facial trauma
78
endotracheal tube
advanced airway performed by advanced practitioners; inserted using laryngoscope; lung sounds auscultated to ensure proper positioning and then inflate cuff (CXR to confirm placement)
79
potential complications of endotracheal tube
long-term use can lead to pneumonia
80
tracheostomy tube
tube surgically placed in between the 2nd and 3rd tracheal rings; usually done if upper airway is obstructed, trauma/spinal cord injuries, choking, anaphylaxis, or misformation of trachea
81
types of tracheostomy tubes
cuffless or cuffed; cuffless used for long-term care and is used to ween off of a ventilator; cuffed used in more acute settings and not long-term
82
what is needed at the bedside with tracheostomy
obturator from current trach, same size trach, one size smaller trach, suction, O2, BVM
83
if trach is dislodged...
use anything to keep airway open; once it closes after the trach falls out the pt is at an immediate threat of losing their airway
84
why use a tracheostomy sponge gauze pad instead of normal gauze?
trach gauze is much tighter weave and wont allow for pieces to come off and enter the incision site
85
dressing care for trach
avoid getting gauze wet and moist to prevent infection and skin breakdown; keep clean dry and intact; strap around neck should be 1 finger breadth tight
86
components of cuffless trach
obturator (stiff plastic used to guide trach into place), cannula, outer tube with flange
87
components of cuffed trach
obturator, cannula, tube to inflate the cuff, outer tube
88
why keep one size smaller trach at bedside?
incase opening becomes inflamed
