Theory final exam Flashcards
PAD
peripheral arterial disease - partial or total occlusion of the artery
PAD can cause
tissue damage
most common cause of PAD
atherosclerosis
which part of the body is most commonly affected by PAD
lower extremities
PAD related to
cardiovascular and cerebrovascular disease
PAD occurs earlier in
pt with DM
hallmark of PAD
intermittent claudication
what increases pain with PAD
elevating the extremity or placing it in a horizontal position
Assessment of PAD
cold and pain with elevation
ruddy or cyanotic when placed in dependent position
prolonged cap refill
skin appears shiny, taut, and dry with no or little hair
bruit may be auscultated
muscle atrophy with prolonged ischemia
diagnostics with PAD
doppler ultrasound, ankle-brachial index, treadmill testing
ankle brachial index equation
ankle systolic/brachial systolic
normal ankle brachial index
1-1.3
management of PAD
reduce serum lipids, daily walking, stop smoking, healthy diet
pharmacologic therapy for PAD
hemorrheologic or antiplatelet agents, vasodilators, or antihyperlipidemics
pentoxifylline (trental)
increases flexibility of RBC and decreases blood viscosity
surgical intervention of PAD
revascularization, endarterectomy, endovascular surgery
arterial revascularization
arterial bypass and vascular grafting
endarterectomy
surgery to remove fatty deposits (plaque) that are narrowing the arteries in your neck
bypass graft
reroutes the blood flow around the stenosis or occlusion
femoral -popliteal graft
Surgical procedure of choice if atherosclerotic occlusion is below the inguinal ligament in the superficial femoral artery. grafts may be synthetic or autologous
post op disappearance of pulse
may indicate thrombotic occlusion of the graft—this is an emergency
post op PAD surgery
ABI not recommended, monitor pulse, color and temp, and cap refill
potential complications after PAD surgical repair
bleeding/hematoma and edema
severe edema, pain and decreased sensation can be indication of
compartment syndrome
PAD home care
avoid pressure on affected extremity, avoid vigorous massage of extremity, avoid exposure to cold, constrictive clothing, and crossing legs, stop smoking
nursing diagnoses of PAD
ineffective peripheral tissue perfusion, activity intolerance, and chronic pain
aneurysms risk factors
age, male gender, HTN, CAD, family history, high cholesterol, lower extremity PAD, stroke, smoking, obesity
most abdominal aortic aneurysms occur
below the renal arteries
aneurysms are usually
asymptomatic until dissection or rupture occurs
classification of abdominal aneurysms
supra-renal, juxta-renal, and intra-renal
aneurysm repair
open repair surgery - done under general anesthesia
open repair of aneurysm can be
trans peritoneal or retroperitoneal
most common complication of endovascular repair of aneurysm
endoleak
endoleak
leak inside the vessels that allows blood to pool up
what med do pt need after endovascular repair
home meds and beta blocker
chronic bronchitis s/s
blue bloater - hypoxia, increase rr, increase CO2, clubbing
emphysema s/s
pink puffer- purse lip breathing, barrel chest, thin, decreased CO2
diagnostic procedures for COPD
CXR, peak expiratory flow rate, pulmonary function test, pulse ox, ABGs, CBC, sputum culture
FEV in COPD
low
pharmacologic management of COPD
bronchodilator, nebulizer inhalers (duoneb), corticosteroids, antibiotics, O2 therapy
surgical treatment of COPD
bullectomy, lung volume reduction surgery, lung transplantation
bullectomy
bullae are resected via thoracoscope
lung volume reduction surgery
procedure done via bronchoscope where a surgeon removes damaged parts of the lung to create more space for the lung to work better
single most important driver of ventilation
CO2 - supplemental oxygen may increase CO2 levels
most precise method of delivering exact amounts of O2
venturi mask
if COPD pt is in respiratory failure
begin high flow oxygen delivery regardless of history, obtain IV access, breathing techniques, and position
complications with COPD
resp. infections, heart failure, fluid retention, pneumothorax, pulmonary hypertension
open vs percutaneous tracheostomy procedure
open - performed in OR. percutaneous - usually performed at bedside in ICU
advantages of tracheostomy
decreases airway resistance, easier airway care, facilitates oral communication and speech, improves oral hygiene
outer cannula
fits into the stoma to keep it open
obturator
device that guides the outer cannula into the stoma during placement of the cannula
inner cannula
fits inside the outer cannula and can be removed for cleaning
what type of tube is used for patients who are ready for decannulation
cuff less tube with reusable or disposable inner cannula
if patient has metal tract tube they cannot get
an MRI
complications of trach
bleeding, infection, mucous plug, injury to laryngeal nerve, injury to esophagus, skin necrosis, false passage
what do you do is there is accidental decannulation
call rapid response, maintain an airway, and reinsert new tube if available
trach pt should always have
two tubes, one the size currently in the pt and one a size smaller
new trach tube care
do not change trach tape for at least 24 hr and physician will perform the first change 7 days after initial insertion
you need to bypass what when suctioning
bypass glottis to decrease cough reflex
what is lost when trach is in place
filtered, warm and humidifies air so the airway becomes drier and produces mucus scabs that can lead to infection, obstruction, and pneumonia
prevent crusting of trach through
proper humidification and hydration
what is used to wean the patient off the tracheostomy
decannulation cap
types of head and neck cancer
oral, salivary, laryngeal, nasopharyngeal, nasal cavity tumors
head and nick cancers are more common in
men than women
squamous cell carcinoma is more common in
smokers and drinkers
head and neck cancer risk factors
long periods of sun exposure, chewing tobacco, bad diet, breathing in chemical, genetic syndromes
leukoplakia is characterized by
irregular, smooth to thickened tissue on the tongue
erythoplakia is characterized by
smooth, velvety clinical presentation with a homogenous surface without ulceration
60-70% or oropharyngeal cancers are due to
HPV
clinical manifestations of head and neck cancer
ulcer or sore area in the head/neck, pain with chewing, trouble breathing, numb feeling in the mouth, unexplained loose tooth, persistent nose bleeds, constant sore throat, ear ringing, lump, pain
diagnosis of head/neck cancer
examination of mouth, throat, and neck, laryngoscopy, CT scan or MRI, PET scan
staging of head and neck cancer
TNM - tumor, number of nodes and location, and metastasis. stages 1-4
treatment options for oral cancer
surgery, radiation, or chemotherapy
transoral robotic surgery
removal of tumor during laryngeal cancer
total laryngectomy
open surgery to remove the entire larynx - stoma is created
radiation nursing care
adequate oral care because radiation causes dry mouth
nursing care of pt with trach stoma
wash stoma daily with moist cloth. clean edges with cotton swab dipped in mixture of hydrogen. remove inner cannula daily
larytube or larybutton
help keep the stoma open during early stages
blom singer laryngectomy tube
maintains latency of the trach after laryngectomy
diagnostics for asthma
CXR, measuring oximetry, H&P, pulmonary function studies
asthma care
identify and avoid triggers, pt teaching, meds
care for severe asthma exacerbation
SaO2 monitoring, ABGs, B2-adrenergic agonist, inhaled anticholinergic agents, oxygen, corticosteroids, IV fluids
teaching of inhaler
use spacer, Short acting beta agonist, clean unit to eliminate bacterial growth
singular
Leukotriene Pathway Inhibitor-Montelukast Sodium
three phases of a perioperative patient and what is our focus in each phase
preoperative- teaching and education, intraoperative- safety and sterile, and postoperative- pain management and prevention of complications
