Bronchogenic Carcinoma, Trauma, Other Pulm Conditions Flashcards
Small cell carcinoma
Oat cell
Non-small cell carcinoma
Squamous cell, adenocarcinoma, large cell undifferentiated
Local mets of carcinoma found in
Pleura, chest wall, mediastinal structures
Distant mets of carcinoma found in
Lymph nodes, liver, bone, brain, adrenals
Bronchogenic carcinoma findings with pulmonary involvement:
- Unexplained __ __
- Hemoptysis
- Dyspnea
- Weakness
- Fatigue
- What kind of breath sounds?
- PNA with ___ ___ due to A/W compression
- Hoarseness with compression of ___ nerve
- ___ or ___ PNA w/ non-reductive cough due to A/W obstruction
- Weight loss
- Wheezing
- Productive cough
- Laryngeal N.
- Atelectasis, bacterial PNA
Bronchogenic Carcinoma: hold PT until ____ and relieves bronchial obstruction
Palliative therapy reduces tumor size
What can happen as effect of bronchogenic carcinoma? (Spine)
Possible fractures from thoracic bone mets with chest compressive maneuvers and coughing
What is flail chest?
Fx of ribs, usually due to blunt trauma — 2+ fractures in 2+ adjacent ribs
What are physical findings with rib fx/flail chest?
- Shallow breathing
- Splinting due to pain
- Crepitation during ventilation over fx site
- Paradoxical movement of fluid section during ventilation cycle
- Confirmation by CXR
Air in pleural space, usually through lacerated visceral pleura from rib fx or ruptured bullae
Pneumothorax
What side do the trachea and mediastinum shift with pneumothorax/hemothorax?
AWAY from injured side
What kind of breath sounds with pneumothorax/hemothorax?
Decreased or absent
increased or decreased tympany with mediate percussion with pneumothorax?
Increased tympany
Blood in pleural space, usually from laceration of parietal pleura
Hemothorax
Blood and edema within alveoli and interstitial space due to blunt chest trauma with or without fx
Lung contusion
What kind of breath sounds heard with lung contusion?
Decreased or crackles
Excessive seepage of fluid from pulmonary vascular system into interstitial space, may eventually cause alveolar edema
Pulmonary edema
Cardiogenic pulmonary edema: results from increased pressure in ____ associated with ___ ventricular failure, ____ valvular disease, ___ valvular disease
Pulmonary capillaries
L
Aortic
Mitral
Non-cardiogenic pulmonary edema: results from increased permeability of ___ membranes, due to ____, hyper____, _____, or ____
Alveolar capillary Inhalation of toxic fumes Volemia Narcotic OD ARDS
What kind of breath sounds with pulmonary edema?
Crackles
What kind of edema seen if cardiogenic?
Peripheral
What does cough produce with pulmonary edema?
Pink frothy sputum
What pattern does pulmonary edema resemble on CXR? What is seen?
Increased vascular markings, butterfly pattern
- atelectasis possible if surfactant lining removed by alveolar edema
Thrombus from peripheral venous circulation becomes embolitic and lodges in pulm circulation
Pulmonary emboli
