Packet 8 - Circulatory Function Part 2 (3) Flashcards
Conducting Airways
A patient is having an allergic reaction, causing the smooth muscle layers of his airway to constrict very tightly.
a. ) impaired function of mucociliary blanket
b. ) swelling of mucosa
c. ) bronchospasm
c.) bronchospasm
P/C factors: allergic reaction, electrolyte imbalance
Smooth muscle layers of airway go into spasms (constrict very tightly).
Conducting Airways
A patient is currently experiencing an allergic reaction that has caused his airway to become very narrow, causing minimized airflow and even possibly stopping airflow completely. What is the most likely cause of this problem?
a. ) impaired function of mucociliary blanket
b. ) swelling of mucosa
c. ) bronchospasm
b.) swelling of mucosa
P/C factors: injury, infection, allergic reaction
Airway gets narrower, minimizing airflow or stopping airflow completely
Conducting Airways
A patient has a history of smoking and breathing unhumidified air, which prevents mucous from getting out. This causes infection, irritation, and inflammation in the lining of the airway. What is the most likely cause of this problem?
a. ) impaired function of mucociliary blanket
b. ) swelling of mucosa
c. ) bronchospasm
a.) impaired function of mucociliary blanket
P/C factors: smoking, breathing unhumidified air, increase or decrease in oxygen levels
Mucous cannot get out, causing infection, irritation, and/or inflammation in lining of the airway.
Respiratory Tissues (alveoli & pulmonary capillaries)
Protect against foreign substances.
a. ) Type I Alveolar Cells
b. ) Type II Alveilar Cells
c. ) Alveolar Macrophages
c.) Alveolar Macrophages
Protect against foreign substances.
Respiratory Tissues (alveoli & pulmonary capillaries)
Produce surfactant, which decreases surface tension within alveoli and facillitate in lung inflation.
a. ) Type I Alveolar Cells
b. ) Type II Alveilar Cells
c. ) Alveolar Macrophages
b.) Type II Alveilar Cells
Produce surfactant, which decreases surface tension within alveoli and facillitate in lung inflation.
Respiratory Tissues (alveoli & pulmonary capillaries)
Actual site of gas exchange.
a. ) Type I Alveolar Cells
b. ) Type II Alveilar Cells
c. ) Alveolar Macrophages
a.) Type I Alveolar Cells
Actual site of gas exchange.
epithelial cells
Respiratory Tissues
Smoking and immune disorders can impair the function of macrophages and can often result in infection. Which type of respiratory tissue has been affected?
a. ) damage to Type I cells
b. ) impairment of Type II cells
c. ) impaired function of macrophages
c.) impaired function of macrophages
impaired function of macrophages.
P/C factors: smoking; immune disorders
Respiratory Tissues
Inhalation of toxic gases, smoke, or anesthesia can cause a decrease in the production of surfactant, which then causes an increase in surface tension, and ultimately atelectasis. Which type of respiratory tissue has been affected?
a. ) damage to Type I cells
b. ) impairment of Type II cells
c. ) impaired function of macrophages
b.) impairment of Type II cells
decrease in the production of surfactant, which then causes an increase in surface tension, and ultimately atelectasis (collapse of alveoli).
P/C factors: decrease in deep breathing / chest expansion; inhalation of toxic gases, smoke, or anesthesia; oxygen toxicity
Respiratory Tissues
Various lung diseases can cause impaired gas exchange. Which type of respiratory tissue has been affected?
a. ) damage to Type I cells
b. ) impairment of Type II cells
c. ) impaired function of macrophages
a.) damage to Type I cells
impaired gas exchange.
P/C factors: various lung diseases
The function of the ______ is to help keep the lungs expanded due to maintaining a negative pressure in relation to pressure in the airways and alveoli.
Decreases friction between chest wall and lung during inspiration/expiration.
The function of the pleura is to help keep the lungs expanded due to maintaining a negative pressure in relation to pressure in the airways and alveoli.
Decreases friction between chest wall and lung during inspiration/expiration.
Lines the outer surface of the lungs.
a. ) Parietal Pleura
b. ) Visceral Pleura
c. ) Pleural Space
b.) Visceral Pleura
Lines the outer surface of the lungs.
Parietal Pleura → lines chest wall
Visceral Pleura → lines outer surface of lungs
Pleural Space → considered a “potential space” (contains only a small amount of serous fluid)
Lines the chest wall.
a. ) Parietal Pleura
b. ) Visceral Pleura
c. ) Pleural Space
a.) Parietal Pleura
Lines the chest wall.
Parietal Pleura → lines chest wall
Visceral Pleura → lines outer surface of lungs
Pleural Space → considered a “potential space” (contains only a small amount of serous fluid)
Considered a “potential space” (contains only a small amount of serous fluid) (vacuum).
a. ) Parietal Pleura
b. ) Visceral Pleura
c. ) Pleural Space
c.) Pleural Space
considered a “potential space” (contains only a small amount of serous fluid)
Parietal Pleura → lines chest wall
Visceral Pleura → lines outer surface of lungs
Pleural Space → considered a “potential space” (contains only a small amount of serous fluid)
A patient has experienced a traumatic injury that has caused air-filled blebs on his lung surface to rupture, allowing air to enter his pleural space. What condition is the patient suffering from?
a. ) Pleuritis / Pleurisy
b. ) Pneumothorax
b.) Pneumothorax
Air enters the pleural space.
P/C factors: Rupture of air-filled blebs on lung surface; traumatic injury
A patient has a lung infection that has caused inflammation of the pleura. What condition is the patient suffering from?
a. ) Pleuritis / Pleurisy
b. ) Pneumothorax
a.) Pleuritis / Pleurisy
inflammation of the pleura
P/C factors: lung infections
