Exam 2 - Respiratory packet Flashcards
Does cough have much Dx value?
Limited, however may be only indicator
Characteristics of cough d/t asthma?
Nonproductive, non-paroxysmal
What other disorder should be considered when dealing with chronic cough, esp. in cases of nocturnal asthma?
Gastroesophageal reflux dz (GERD)
What is aspiration pneumonitis (in relation to GERD)?
acid reflux from stomach is aspirated into lungs
What is an acute cough?
Cough lasting <3 wks
What is acute cough most often d/t?
viral tracheobronchitis/URTI
What is a chronic cough?
Cough lasting >3 wks
Common causes of chronic cough?
asthma, airway hyper-reactivity, smoking
What happens with the tongue with a disorder of CN XII?
Inability to generate “tongue sounds” “L”, “D”, “T”, “N”
What happens with the larynx with a disorder of CN IX & X?
trouble generating sound - dysphonia. (Can’t say aaaaah)
General rule regarding airways and determining if epithelium is ciliated?
The harder the surrounding tissue, the greater the likelihood that the underlying epithelium is ciliated
Is the trachea pain sensitive?
NO unless significantly irritated
Are the primary bronchi pain sensitive?
NO unless significantly irritated
What is a pancoast tumor?
lung cancer near superior sulcus of lung
Classic presentation of pancoast tumor?
Middle aged male smoker w/ sudden onset of neck/shoulder/arm pain
Why do sound and vibration generated in the larynx normally reach the chest wall?
airways are patent, pleural surfaces have to be intact and functional
What is an extra-mural obstruction of the airway?
Outside the wall of the airway; bronchogenic carcinoma or enlarged mediastinal lymph nodes
What is an intra-mural obstruction of the airway?
In the wall of the airway; bronchogenic carcinoma
What is an intra-luminal obstruction more likely to lead to?
Complete obstruction
What happens to sound/vibration with a partial obstruction?
Will be transmitted to chest wall
What happens to sound/vibrations with a complete obstruction?
no airflow = no sound or vibration to chest wall
What is atelectasis?
collapse of previously-inflated lung tissue
What is the rate of lung collapse?
gradual
What happens to air movement during atelectasis?
no air movement to/from affected area of lung
