1JO2 Unit 7 Final exam Flashcards
What are the 4 key functions of the respiratory system?
Supplying oxygen to the body for energy production
Removing carbon dioxide as a waste product
Maintains acid-base balance
Maintaining heat exchange ( not as important)
What does the pleural cavities contain?
The lungs
What does the mediastinum contain?
The esophagus, trachea, heart, and the great vessels
Where is the trachea located in relation to the esophagus?
Anteriorly to the esophagus. (In front of it)
Where does the trachea part into bronchi?
At the T4 - T5
Where does gas exchange occur?
Alveoli, bronchioles, alveolar ducts, alveolar sacs.
Where does gas exchange not happen?
The bronchi
What lung is shorter? Why?
The right lung is shorter because it is competing for space with the liver.
Which lung is narrower? Why?
The left lung because it is competing for space with the heart.
Which lung has 3 lobes?
the right lung
Where is the 3rd lobe of the lung located?
In the Right Middle Lobe and is only present on the anterior of the chest.
Where is the apex of the lung? (Anteriorly)
It is 3 - 4 cm above the clavicles.
Where is the base of the lung ?(Posteriorly)
It sits on the diaphragm at around the 6th rib.
How much do the lungs inflate? (from what rib to what rib)?
The base of the lung moves from the T10- T12
(actual question on the slideshow)
The apex of each lung is located at the:
a) Level of the diaphragm
B) Area slightly over the clavicle
c) Level of the sixth rib
d) Left oblique fissure
B
Explain what happens when we breath in.
The pressure inside the lungs drops, which allows air to move inward and then the diaphragm moves downwards and the thoracic cavity expands to allow more air to move in and allows for the lungs to expand more.
When are accessory muscles used to breath?
When some one is exercising and has shortness of breath or with a respiratory illness.
How is breathing controlled?
It is an autonomic process which is controlled by the brainstem.
What is the stimulus that causes us to breath?
The increase of CO2 in the blood, which is called hypercapnia.
What is the order of doing a respiratory assesment?
Inspection, palpation, percussion, auscultation - posterior then anterior.
What are some questions you can ask when doing a focused respiratory assessment?
What brings you here today?
* Do you have a cough?
* Do you cough up phlegm or sputum? Color?
* Any shortness of breath?
* Difficulty breathing in supine position?
* Any chest pain with breathing?
* Any past history of respiratory infections (pneumonia)
* Any past history of respiratory disease (COPD, asthma)
* Any family history of respiratory disease?
* Assess respiratory risk factors: smoking history
* How many/day? Ever smoked? How long? 2nd & 3rd
hand smoke exposure? Ever tried to quit?
* Environmental exposure to conditions that affect breathing? Work or home environment, etc.
* Potential impact of respiratory system on daily living (participation in leisure activities, exercise, work, chores, sexual activity, sleeping, ADL’s).
What position indicates that the client is having trouble breathing?
The tripod position where they are bent over in the chair.
What does it mean to be barrel chested?
When the side of the chest is the same width as the front of the chest.
What is barrel chested a result of ?
When someone has chronic respiratory disease like COPD. Or where someone has shortness of breath for a long period of time constantly.
