Bow is vital capacity determined? - CORRECT ANSWER: Combining inspiratory and
expiratory reserve, and tidal volume


In the pulmonary vasculature, which vessel carries deoxygenated blood to the
pulmonary system? - CORRECT ANSWER: Pulmonary artery


True or False... Airway Airflow is inversely related to the resistance that the air
encounters as it moves through the airways - CORRECT ANSWER: True


True or False... Volume of air that moves into and out of the air exchange portion of the
lungs is directly related to pressure difference between the lungs and atmosphere -
CORRECT ANSWER: True


What are the 4 forces overcome by the respiratory muscles? - CORRECT ANSWER: 1.
Elastic recoil of the lungs, measured as compliance
2. Elastic recoil of the chest wall
3. Surface tension
4. Airway resistance


What determines lung compliance? - CORRECT ANSWER: elastin and collagen fibers
of lung, its water content, and surface tension


What do the vocal cords contribute when it involves swallowing? - CORRECT
ANSWER: They contribute to blocking of airways when swallowing, thus preventing
food from entering the lungs.

,What does the Tracheobronchial Tree consists of - CORRECT ANSWER: trachea,
bronchi, and bronchioles


What is aspiration pneumonia? - CORRECT ANSWER: is a type of lung infection that is
due to a relatively large amount of material from the stomach or mouth entering the
lungs


What is COPD? - CORRECT ANSWER: Irreversible decrease in the ability to force air
out of the lungs.


What is lung compliance? - CORRECT ANSWER: It is the stretchability of our lungs.
The more the lungs can expand the more the compliance.


What is pleural effusion? What breath sounds would you hear? - CORRECT ANSWER:
Build up of fluid in the viceral space of the lungs. This is more commonly reffered to as a
build up of water on the lungs. The sounds. Since lungs are unable to expand properly,
upon auscultation one would hear diminished or absent sounds on the lower portions of
the lung.


What is pneumothorax? What breath sounds would one hear? - CORRECT ANSWER:
Abnormal collection of air in the visceral space of the lungs, this is known as a collapsed
lung. Crackles is heard upon auscultation, also one would have diminished or absent
breath sounds.


What is pulmonary fibrosis? What are the clinical manifestation that the nurse would
find? What happens to the breathing of the patient as they attempt to compensate? -
CORRECT ANSWER: Scarring of the alveoli thus reducing compliance of the lungs due
to reduction of the elasticity of the tissues. Client presents with shortness of breath, dry
hacking cough, clubbing. To compensate, patient would take shallow deep breaths


What is the name of the nerves that innervate the diaphragm? What would happen if an
injury occurs at the C4 region? What respiratory intervention can the nurse expect as a
result of the injury? - CORRECT ANSWER: Phrenic nerve roots. Damage to C4 region
will cause damage to the phrenic nerve roots, thus causing no muscle contraction of the
diaphragm. Patient will most probably need mechanical ventilation.

, What is the primary role of mucociliary blanket? - CORRECT ANSWER: Trap foreign
objects and bacteria which doesn't allow entry to the lungs


What is the priniciple muscle for inspiration? What is the motion when contracted? -
CORRECT ANSWER: diaphragm. the abdominal contents move downward and
forward.


What muscles are involved in expiration? - CORRECT ANSWER: Expiration of the
lungs is usually passive. Relaxing the inspiratory muscles allows the elastic recoil of the
lungs to reduce the volume of the thoracic cavity passively


Which type of penumonia are you at high risk if the swallowing mechanism is impaired?
- CORRECT ANSWER: aspiration pneumonia


Why does Fibrosis cause a decrease in lung compliance? - CORRECT ANSWER: It
causes an increase in elastic tissue, which causes increases stiffness thus leading to
lower compliance


Why does Pulmonary emphysema increase lung compliance? - CORRECT ANSWER:
This changes the elastic recoil of lung tissue


Why is lung capacity always greater than vital capacity? - CORRECT ANSWER: The
lungs never empty completely, thus causing a greater lung capacity over vital capacity
Cell differentiation - CORRECT ANSWER: process by which dividing cells change their
functional or phenotypical type.


Cervical Cancer - CORRECT ANSWER: Malignant cell growth in the cervix; can be
caused by HPV virus


Cervical Cancer treatment - CORRECT ANSWER: if PAP smear is negative (normal)
