chapter 66 (exam 2) Flashcards
(41 cards)
patients with respiratory diseases have increased risks for complications due to:
breathing function
medication use
drug interactions
what are many respiratory diseases caused by?
use of tobacco products
what are the anatomical structures of the respiratory system?
sinuses, nasal cavity, larynx, pharynx, trachea, bronchi, lungs and pleura
what type of cells line the respiratory tract?
ciliated epithelial cells and mucous secreting goblet cells
what are the two types of respiratory disease?
upper resp. tract and lower resp. tract
these types of diseases affect the nose, sinuses, pharynx, larynx rhinitis, sinusitis, pharyngitis, flu
acute upper respiratory tract
this type of disease includes allergic rhinitis (hay fever)
chronic upper resp. tract
what are the more common UR infections caused by?
infections and allergies
how are UR transmissed?
inhalation of airborne droplets, indirectly by contaminated hands or articles freshly soiled with discharge of nose or throat of infected person
what does acute lower resp. tract disease include?
acute bronchitis or pneumonia
what does chronic lower resp. tract disease include?
TB, asthma, COPD, chronic bronchitis, emphysema,
this is an acute resp. infection that involves large airways such as trachea and bronchi.. primary symptoms are cough with or without phlegm and may last up to three weeks
acute bronchitis
what are the symptoms of lower resp. tract disease?
wheezing, shortness of breath, or chest tightness
what is the most common cause of TB?
mycobacterium tuberculosis (a rod shaped bacterium)
an infection and subsequent inflammation of the lungs, may be caused by either viruses, bacteria, fungi, mycoplasma or parasites
Pneumonia
this is a chronic, infectious, and communicable disease with worldwide public health significance as a cause of disability and death, esp. in developing countries
tuberculosis (tb)
what are the tests used to determine exposure to TB?
TST..aka mantoux test, PPD
Interferon gamma release essay (IGRA)
This is a chronic resp. disease consisting of recurrent episodes of dyspnea, coughing, and wheezing leading to bronchial inflammation and muscle contraction
asthma
what is the most common type of asthma?
extrinsic (allergic or atopic): allergic triggers from outside the body
this is an exaggerated inflammatory response triggered by inhalation of an environmental allergen such as dust pollen, or smoke
extrinsic asthma
the triggers of this asthma is emotional stress, GERD, obesity..usually seen inadults
intrinsic
what does COPD stand for?
chronic obstructive pulmonary disorder
what are the two most common types of COPD?
emphysema and chronic bronchitis
what is the physiology of the respiratory system?
Respiratory tract from nasal cavity to lungs/passageway for air exchg.
- Fresh air inhaled in the nasal cavity into lungs
- Exhaled air contains carbon dioxide (air that leaves the body)
- Gas exchange (at the cellular level) occurs in the alveoli at ends of bronchioles
- Cardiovascular system works w/ the respiratory system to pump oxygenated bl.
from lungs to all cells in the body and deoxygenated bl. back to the lungs.
