Ch. 22, 24, 25, 26 Flashcards
COPD stands for
chronic obstructive pulmonary disease
- it is an umbrella term
COPD encompasses
- chronic bronchitis (airway problem)
- pulmonary emphysema (alveolar problem)
^neither get better, can halt progression but cannot repair or turn it around once the damage has started
- tissue damage is not reversible, increases in severity, eventually leads to respiratory failure
emphysema
- alveolar membranes (grape-like clusters, where gas exchange occurs) breakdown
- loss of lung elasticity and hyperinflation of the lung- get smoother, decreases surface area to have gas exchange, stiff- air-trapping
- typically from smoking, pollution, irritants in the airway
chronic bronchitis
inflammation of the bronchi and bronchioles caused by chronic exposure to tobacco smoking, irritants to airway, pollution
- inflammation, vasodilation, congestion, mucosal edema, bronchospasm
- production of large amounts of thick mucous (when coughing)
- SOB, fatigue, coughing- bringing up phlegm**
air-trapping
caused by loss of elastic recoil in the alveolar walls, overstretching and enlargement of the alveoli into bullae, and collapse of small airways (bronchioles)
- occurs with emphysema patients
pursed lip breathing
emphysema patients classic presentation
- increases pressure in chest/abs
- increases pressure to push air trapped in alveoli into the lungs
complications of COPD
- hypoxemia/ tissue anoxia- not good gas exchange = not good enough oxygen in bloodstream to perfuse the tissues
- tired, fatigued, achey legs
- acidosis b/c patients are retaining CO2 (seen in ABGs, < 7.35)
- respiratory infections b/c of mucous containing bacteria
- cardiac failure, especially cor pulmonale- R side of heart pumps to lungs-stiff, now R side of heart is working hard=floppy muscle and R-sided HF
- cardiac dysrhythmias- PVCs
COPD clinical manifestations
- history- hx of smoking (past/current), SOB, difficulty on exertion, chronic cough w/ mucous (bronchitis)
- general appearance: barrel chest (emphysema), nail clubbing: bulbed fingernails
- respiratory changes: SOB, esp w/ exertion
- cardiac changes
dyspnea assessment guide
indicates the amount of SOB you are having art this time by marking the line; basically a pain scale but for SOB
0- no shortness of breath
10- shortness of breath as bad as can be
general s/sx of COPD
- prolonged expiratory time- longer breathing out time to push air that is trapped out of lungs
- easily fatigued
- frequent respiratory infections
- use of accessory muscles to breathe
- orthopneic
- cor pormonale (late in disease)
- wheezing
- pursed-lip breathing
- dyspnea
- digital clubbing
- anxious
s/sx specific to emphysema
- barrel chest
- thin in appearance
- pursed-lip breathing
- pink skin (hyperventilate to compensate)
- CO2 retention
- minimal cyanosis
- talking in short/couple words/sentences
- hyperresonance on chest percussion
s/sx specific to bronchitis
- chronic cough w/ increased sputum production
- dusky, cyanotic skin color
- resp acidosis
- will need to be on O2
- cor pormonale
- clubbing of fingers
- increased RR, Hbg
- hypercapnia (increased pCO2)
- leads to R-sided HF
pink puffer is
emphysema
blue boater is
chronic bronchitis
COPD laboratory assessments
- ABG values for abnormal oxygenation, ventilation, and acid-base status (these hurt, usually radial artery- stay with patient, ensure that they are okay)
- sputum samples
- CBC (elevated WBC=infection)
- H&H blood tests (Hbg & Hct)
- serum electrolyte levels (not eating right because of difficulty to breathe)
- serum AAT level
- chest x-ray
- pulmonary function test (PFTs)
COPD assessment: chest x-ray will show
can show effusion, PNA, opacity in lungs, cardiac enlargement
COPD assessment: PFT
patient blows into “pipe” and PF reads on graph
(encourage patient to blow hard)
why get a serum AAT level with a COPD patient?
AAT is a protein that we have in our body that protects the lungs from enzymes (coats them)
- some people have congenital lack of AAT, so they are more prone to COPD
COPD patient problems: how is the patient impacted by COPD?
- decreased gas exchange
- weight loss
- anxiety (d/t SOB, chronic illness)
- decreased endurance
- potential for PNA: avoid large crowds, PNA vaccine, yearly influenza vaccine
*think ABCs first, then psychosocial
nursing management for COPD
- no smoking!
- airway management: deep breathing, purse-lip breathing
- cough enhancement: how to cough
- drug therapy
- oxygen therapy: at home oxygen, teaching
- positioning/breathing techniques- no lying flat
- pulmonary rehab: exercise on monitors to increase endurance level baseline
COPD drug therapy
corticosteroids (help inflammation in respiratory tract, increases space to allow better airflow)
- fluticasone
- prednisone
- inhaled steroid and long-acting dilator: Advair (wash mouth out! ,not a rescue)
mucolytics
- acetylcysteine (Mucomyst/Mucinex)
- guaifenesin: thins mucous
short-acting beta agonist
- albuterol (Ventolin): rescue med
long-acting beta agonist
- salmeterol (Serevent)
cholinergic antagonist
- ipratropium (Atrovent)
- tiotropium (Spiriva)
rescue medication for COPD
short-acting beta agonist
- albuterol (Ventolin)
COPD med: long-acting beta agonist
Salmeterol (Serevent)
COPD evaluation of (ideal) outcomes
- attain and maintain gas exchange at a level within his/her chronic baseline values
- achieve an effective breathing pattern that decreases the work of breathing
- maintain a patent airway
- achieve and maintain a body weight within 10% of his or her ideal weight
- have decreased anxiety
- increase activity to a level acceptable to him or her
- avoid serious respiratory infections (crowds, grandkids with illnesses)
- patient may need/be on palliative or hospice care- decrease anxiety and improve quality of life
- med compliant
- nutritional regimen
- include patient and family in plan of care
influenza sx
- severe HA
- muscle ache (myalgia)
- fever
- chills
- fatigue
- weakness
- anorexia
influenza: contagious window
when patient presents with sore throat, cough, rhinorrhea
- little kids and elderly most at risk
- droplet precautions (mask)
- viral infection
influenza vaccine
- annual
- makes sx lesser if get the flu
- extra layer of protection/prevention
influenza interventions (drugs)
- antivirals if within certain window to minimize symptoms: oseltamivir (tamiflu), zanamivir (relenza)
- treat by symptom management: tylenol, fluids
pulmonary tuberculosis
- highly communicable disease caused by mycobacterium tubericulosis
pulmonary tuberculosis: incidence and prevalence
- 10 million people dx in 2017
- 1.6 million died from TB in 2017
- incidence steadily decreasing in North America
- increase related to onset of HIV* (HIV and TB go hand in hand, TB kills people with HIV)
- seen in poor areas
pulmonary tuberculosis is transmitted via
aerosolization (airborne: N95)
- bacterial infection
- bacterial is sucked into lungs (breathed in), causing tissue to die/be coughed up, ends up spreading to whole body
pulmonary tuberculosis risk factors
- TB and HIV (HIV patients)
- anyone that is immunocompromised (ie post-chemo)
- older, elderly, babies
- incarcerated persons, multi family homes (living in crowded settings)
TB assessment: history
- living arrangements
- have HIV
- any recent exposure
TB assessment: s/sx
- progressive fatigue
- anorexia
- malaise
- SOB*
- unintentional weight loss*
- chronic, productive cough*
- rusty sputum*
- night sweats*
- hemoptysis (advanced state)
- low-grade temp (late afternoon)
- pleuritic chest pain (not typical)
TB assessment: laboratory tests
- TB skin tests (screening)
- chest x-ray
- sputum studies (3 specimens collected on 3 different days)
diagnostic assessment for TB
- NAA test (most accurate and rapid)
- sputum culture confirms dx
- tuberculin (mantoux) test: PPD given intradermally in forearm
- blood analysis
- chest x-ray (look for granulomas on the lungs)
TB diagnostics: PPD tests
- induration of >10 mm diameter = positive exposure
- must be checked/read after 48-72 hours from plant* (wait the 72 hr for someone suspicious of TB)
- PPD implanted right under the skin
TB diagnostics: blood analysis
- QuantiFERON-TB Gold** ( this tells you if you have antibodies for TB- positive means need chest x-ray to confirm)
- T-SPOT TB
- GeneXpert Omni
TB diagnostics: positive PPD findings
area of induration is swollen (NOT red or inflamed) (measure the lump not the redness)
- >5mm: HIV + group or recent close contact with active TB (super high risk)
- >10mm: residents of long-term care facilities, IV drug abusers and medically underserved populations, health care workers (a little higher risk)
- >15mm: general public without risk factors (super low risk)
what does a positive PPD skin test mean?
- positive reaction does not mean active TB infection is present, but it does indicate EXPOSURE to TB or dormant disease
- a positive PPD means that the person needs to go into the next stage of testing (airborne precautions, bloodwork/sputum/chest x-ray next)
interpreting TB: patient problems
- potential airway obstruction
- potential for development of drug-resistant disease and spread infection
- anxiety
- weight loss
- fatigue
TB interventions
- safety and infection control
- combination drug therapy with strict adherence (for 6-12 (4-6) months)
- negative sputum culture indicative of patient no longer being infectious; respiratory isolation until negative sputum culture (need 3 consecutive negative sputum cultures on different days)
- decreased activity
- frequently on out-patient basis
drug therapy for TB
- isoniazid (INH)
- rifampin (RIF)
- pyrazinamide (PZA)
- ethambutol (EMB)
taken daily for 4-6 months
no alcohol, turn secretions orange (normal), nausea
hard on liver (worry about jaundice (yellow eyes))
compliance with treatment is very tough (DOT “babysitting taking their pills”)
pulmonary embolism
a collection of particulate matter- solids, liquids, or air- enters venous circulation and lodges in the pulmonary vessels
- thrombus: a blood clot in the lung
- DVT broke off, traveled through the vein, got stuck in the vasculature of the lungs
- fat embolus: with bone fractures
onset of PE
can be abrupt or slow (smaller)
risk factors for PE
- prolonged immobilization (static blood)*
- smoker*
- birth control/hormones*
- central venous catheters*
- surgery*
- pregnancy*
- obesity
- advancing age
- general and genetic conditions that increase blood clotting
- hx of thromboembolism
dx of PE
- pulmonary angiogram
- MRI
- V/Q scan
PE s/sx
respiratory:
- dyspnea*
- low SpO2*
- tachypnea*
- pleuritic chest pain
- dry cough
- hemoptysis: coughing up blood*
cardiac:
- distended neck veins* (d/t back up of blood)
- tachycardia
- syncope
- cyanosis
- systemic hypotension* (will go into shock)
- abnormal heart sounds
- abnormal EKG
- low grade fever
- petechiae (pinpoint red spots, chest or on body)
- flu-like sx
PE lab tests
- ABGs
- PaO2 - FiO2 ratio falls (low- pt on O2 and not perking up)
- pulse ox
- imaging assessment: chest CT scan
PE analysis (patient problems)
- hypoxemia
- hypotension
- potential for excessive bleeding (b/c DIC and treatment is blood thinners)
- anxiety (going into shock)
PE interventions
- patient problems
- rapid response team: if patient was fine a minute ago now they are SOB, hypotensive, has petechiae
- non-surgical management
- surgical management
PE non-surgical management
- ongoing assessments: bloodwork, imaging
- meds: blood-thinners- warfarin (coumadin) PO, heparin IV, lovenox
antidotes for warfarin and heparin
- warfarin: vit K
- heparin: protamine sulfate
PE surgical management
- embolectomy
- vena cava filter (greenfield filter): traps blood clots as they travel up the vena cava, preventing them from reaching the lungs. the cone-shaped design alls blood to flow around the captured clot (patient is on blood thinners, this patient has probably had multiple blood clots, this is removable)
