Diagnostic & Pathological Terms & Meanings

listening to sounds within the body ausciltation
ausciltation procedure used for diagnosing conditions of lungs, pleura, heart & abdomen, as well as condiiton of fetus during pregnancy
percussion over a solid organ produces a ____ sound dull
percussion over a hollow organ produces a ____ sound resonant
resonant hollow note
resonance is replaced by dulness, during purcussion, when lungs/pleural cavity are filled with fluid, making them more dense
when the pleura are thickened by inflammation, scarring or neoplastic cells it casues a pleural rub
a pleural rub is heard by auscultation
a pleural rub can be felt by placing the fingers on the chest wall
when there is fluid on the alveoli, a fine crackling sound can be heard during inspiration on auscultation
indicates chest congestion & inflammation in larger bronchial tubes rhonchus/rhonchi
often green or brown sputum, resulting from infection or asthma purulent
blood-tinged sputum is suggestive of TB or malignancy
growing sputum in a nutrient medium to detect presence of a pathogen sputum culture
culture & sensitivity (C&S) studies indetify the sputum pathogen & determine which antibiotic will be effective in destroying/reducing its growth
strained, high-pitched, relatively loud sound made on inspiration stridor
usually caused by tightening on bronchi in patients with asthma wheeze
croup the most common causative agents of this acute viral infection are flu viruses & respiratory syncytial virus (RSV)
respiratory syncytial virus (RSV) common cause of bronchiolitis, bronchopneumonia, & common cold, especially in children
in tissue culture, forms syncytia or giant cells, so that cytoplasm flows together RSV
corynebacterium is diptheria bacterium
when a patient has diptheria inflammation occurs, and a leathery, opaque membrane forms in pahrynx & respiratory tract

acute atelectasis requires removal of underlying cause & therapy to reopen airways
pulmonary artery pressure rises & right side of heart must work harder to pump blood leading to right ventricular hypertrophy & heart failure due to emphysema
most frequent fatal malignancy lung cancers
non-small cell lung cancers adenocarcinoma & squamous cell carcinoma
adenocarcinoma dervied from mucus-secreting cells
squamous cell carcinoma derived from the lining cells of the upper airway
stage of a tumor determined by size & location, including any distant areas of spread
when cancer is advanced, with spread to lymph nodes or mediastinum, or in the case of metastic disease, the therapy options include radiation & chemotherapy
surgery may curative for _____ tumors localized
small cell lung cancer derives from small, round to oval secretory cells found in pulmonary epithelium
spreads rapidly through the lymphatic system & bloodstream; has a poor prognosis small cell lung cancer
include radiation & chemotherapy treatements for small cell lung cancer
pneumoconiosis forms are named by the type of dust particle inhaled
anthracosis, asbetosis & silicosis are all types of pneumoconiosis
pneumococci, staphylococci & other bacteria, fungi & viruses are etiological agents of pneumonia
pneumonia infection damaged alveolar membranes so that an exudate leading to the aveoli sacs being "glued together"; this makes air exchange less effective
lobar pneumonia fluid, blood cells, and other debris consolidate, or solidify, within the alveoli of one or more lobes
bronchopneumonia consolidation occurs primarily in the terminal bronchioles, affecting a smaller area and resulting in milder symptoms
community-acquired pneumonia results from contagious respiratory infection, caused by variety of viruses/bacteria
hospital-acquired pneumonia acquired during a hopsital stay
aspiration pneumonia caused by material lodging in bronchi/lungs
large collection of pus, bacterial infection, in lungs pulmonary abcess
caused by inability of heart to pump blood which backs up in pulmonary blood vessels & fluid seeps out into alveoli & bronchioles pulmonary edema
requires immediate medical attention, including medications, oxygen in high concentrations & patients maintaining sitting position acute pulmonary edema
often causes acute pleuric chest pain, & may be associated with bloody sputum, fever & respiratory insufficiency pulmonary embolism
diagnosis of PE is provided by ____________ that reveal areas of lung that lack adequate blood supply ventilation-perfusion scans
CT scans are able to reveal obstruction of pulmonary vessels in order to diagnose PE
may be result of any inflammation/irritation caused by TB, pneumonia, or pneunoconiosis pulmonary fibrosis
chronic disorder of unknown origin, involing development of inflammatory lesions & proliferation of lymphatic tissue sarcoidosis
bacilli invade lungs producing small tubercules of infection; usually asymptomatic & can be seen on chest xray TB
uses intradermal injection to test for previous or active TB Mantoux skin test
mesotheliomas are composed of mesothelial tissue
the two types of pleural effusion are exudates & transudates
pleurisy (pleuritis) causes pleurodynia, dyspnea & in chronic cases pleural effusion
accompanied by chest pain, rapid breathing, weak pulse, dizziness & cough pneumothorax
pneumothorax lung collapse which may occur spontaneously or as a result of trauma

diagnostic procedures used to diagnose pneumonia include chest xrays, sputum culture & percussion
oxygen therapy, antibiotics & analgesics are used to treat pneumonia
once inhaled they infect lower respiratory tract, causing inflammation of bronchioles & alveoli bacilli of TB
the immune system encloses the bacilli in small firm nodules called tubercles progression of TB
treatments for emphysema include reconditioning exercises, relaxation exercises of dyspnea & breathing retraining
medications used to treat emphysema help improve breathing efficiency
decreased compliance of lung tissue & diminished ability of lung to fully expand indetifies atelectasis as a restrictive lung disease
airway obstruction by secretions/foreign body or compression due to fluid/air/tumor in long may lead to collapse of alveoli
