Q

How does diffusion work in respiratory system?

A

Movement of air and O2 from atmosphere into alveoli —-> O2 crosses into pulmonary capillaries —> CO2 diffuses out of pulmonary capillaries into alveoli

25
What do we inspect for with respiratory?
Breathing pattern, rate/depth, symmetry, movement, accessory muscles?, skin color, membranes, clubbing of fingers, etc.
26
What are some palpation things we do for respiratory?
99 - Fremitus (increased = liquid/pneumonia, fibrosis, etc.), decreased = obstructed or collapsed. Tender areas.
27
What does hyperresonance mean?
Emphysema, pneumothorax
28
What does decreased resonance mean?
tumor, plueural thickening, pneumonia, etc.
29
What are crackles and rales?
Crackling/poping with inspiration - rales are harsher - begin in bases and may clear with cough..... Pulmonary edema? Fluid overload?
30
Wheeze - when?
W/inspirations and/or expiration ---- Asthma?
31
Rhonchus/Course crackles - ?
low pitched, snoring, gurgling ---- smokers? Aspiration of foreign body?
32
Pleural friction rub - ?
Grating, creaking, rubbing === pleural inflammation?
33
Strider - ?
rough w/ inspiration. Obstruction of the larynx!
34
Does having trouble breathing make you anxious?
YES
35
What is the best position for a respiratory assessment?
Sitting upright!
36
What are some radiographic tests for respiratory?
Chest XRay, in bed = anterior to posterior, in machine = posterior to anterior, MRI, Pulmonary Angiogram, ventilation perfusion scan, etc.
37
What's the preferred method for diagnosing PE?
MRI
38
What does pulse oximetry measure?
Arterial oxygen saturation
39
What is the pulmonary function test?
uses a spirometer to measure lung volumes and capacities during forced breathing.
40
What is a bronchoscopy? When is it contraindicated?
trachea/bronchial treat. Contraindicated in asthmatics - try not to take an unstable patient back as well unless absolutely necessary! CHECK FOR GAG REFLEX AFTER to tell them when they can eat!
41
What is a laryngoscopy?
Larynx. Pre-op = meds, vitals, consent, allergies to drugs, npo, remove dentures, O2 given, etc.
42
What are some post op things to do for an endoscopy?
Keep patient on side when unconscious and semi-fowler's when conscious. Check vitals, gag reflex, assess breath sounds, o2, ABG's, etc.
43
What is a thoracentesis?
Aspiration of pleural fluid or air from the pleural space through a needle.
44
How should a patient lie when having a thoracentesis done?
Either hunched forward or on unaffected side!
45
What are some complications for a thoracentesis?
Pneumothorax (watch for diminished/no breath sounds), hemothorax, infection, injury to diaphram, liver, or spleen.
46
What is a lung biopsy?
They sick a needle in and biopsy a part. That's about it! The usual stuff after - like assessing, breath sounds, etc.
47
What are some lab tests for respiratory?
Maxtoux test, ABG's, CBC, WBC, cultures, sputum analysis, skin testing, etc.
48
If you need to collect sputum, when should it be done?
First thing in the morning, if possible!
49
What's the preferred way to open an airway?
Head tilt & chin lift.
50
If the patient has a suspected neck injury, use the __ ___ maneuver to open the airway
Jaw-thrust (you thrust the jaw up!)
51
What are some general nursing interventions for respiratory?
Elevated HOB (#1!!!!), stop smoking, oral hygiene (to prevent pneumonia), increase hydration, balance nutrition, early and frequent assessments, infection control, mental health support, etc.
52
What are some respiratory therapies?
O2 therapy, IPPB (intermittent pressure positive breathing), Incentive Spirometry, Chest Physiotherapy (diaphragmatic breathing, pursed-lip breathing (slows down expiration), coughing, postural drainage
53
What are some things that a respiratory therapist does?
CPAP, BiPAP, O2, IS, trach care, pulmonary functioning tests, CODES, etc.
54
What are some antitussives (used to stop non-productive coughs) ?
Opioids (codeine, hydrocodone), nonopioids (benzonatate - tessalon perles), Robittusin - dextromethorphan)
55
What are some decongestants/vasoconstrictors? Used for????
Used for nasal allergies, opening nasal passages - Naphazoline, Phenylephrine, Pseudophedrine (Sudefed)
56
What are expectorants?
liquifies sputum and increased mucous flow, stimulates a productive cough. Guaifenesin!
57
Mucolytic - def? example?
Administered by inhalation to liquify secretions, facilitates sputum removal. Used for the common cold and sinusitis - acetylcysteine.
58
What are a few examples of bronchodilators?
Beta 2 Agonists & Methyl Xanthenes
59
What do beta 2 agonists do?
Relax bronchial smooth muscle to relieve bronchospasms and produce bronchodilations. Used for acute asthma attack. Watch with patients who have tachycardia. Albuterol, Salmeterol, etc = examples.
60
What are (Methyl) Xanthenes?
Bronchial dilation - due to smooth muscle relaxation. Used to treat bronchial constriction with COPD, status asthmaticus. Has stimulating effects on CNS - aminophyline, theophyline are examples.
61
With theophyline, can it be given IV?
Yes - monitor VS, EKG, give with histamine blockers (pepcid), draw blood levels ever 6-12 months for toxicity!
62
What do corticosteroids?
Inhibit inflammatory response in airways. Reduce edema and may aid in increasing responsiveness in bronchial smooth muscle to beta-agonists.
63
What are some examples of an intranasal steroid?
Dexamethasone, Fluticasone, Flunisolide, Budesonide
64
What are antihistamines used for in respiratory problems?
treat allergies, hayfever, urticaria, dries mucosal membranes and reduces edema.
65
What are some nonsedating antihistamines?
Fexofenadine, Loratadine
66
What are some sedating antihistamines?
Chlorpheniramine (Chlortrimetron), Promethazine (Phenergan)
67
What do mast-cell stabilizers do and what are some examples?
They are for allergies, exercise asthma - examples = cromolyn sodium, intal, crohom
68
What do leukotriene receptor antagonist's do - examples?
protects against allergy triggers, reduces asthmatic symptoms. Examples = montelukast and zafirlukast.
69
What do anticholinergics/vagal blockers do? Examples?
Prevent bronchospasm and reduces mucous production. Example = ipratropium (Atrovent)
