Nursing 3000 Exam test queries and
answers graded A+
Where is the site of O2 & CO2 exchange? - ANS✅✅Pores of Kohn
What is the point of surfactant? - ANS✅✅To keep the alveoli open
How much fluid should be in the pleural space? - ANS✅✅20-25ml
To simply movement of air in and out of the lungs - ANS✅✅Ventilation
Shortness of breath - ANS✅✅Dyspnoea
Elastin fibers in the alveolar walls and bronchioles allow the lungs to recoil back after inspiration is
over, in essence creating a passive expiration. This is called... - ANS✅✅Elastic Recoil
What two diseases are linked to the lost or decreased ability to have elastic recoil? - ANS✅✅COPD
and Asthma
The term used to describe the ease of the lungs to expand with inspiration. - ANS✅✅Compliance
What happens when we have decreased compliance in the lungs? - ANS✅✅Lungs are more
difficult to inflate.
Seen with an increase in fluid such as ARDs, PNA, pulmonary edema, or lost elasticity such as in
pulmonary fibrosis or sarcoidosis, restricted lung movement such as pleural effusions
What happens when we have increased compliance in the lungs? - ANS✅✅Lungs inflate to
easily/there is not enough elasticity. Seen in destroyed alveolar walls such as in COPD
How O2 and CO2 moves across the alveolar-capillary membrane. - ANS✅✅Diffusion (high to low
concentration)
Used to measure arterial oxygenation. - ANS✅✅Oximetry
, Respond to changes in pH, Hydrogen, CO2. Depending on the changes sensed by these receptors,
the medulla will change the respiratory rate. - ANS✅✅Chemoreceptors
Found in lungs, upper airway, chest wall, and diaphragm and stimulated by various factors to control
respiration. Stimulants can be irritants, muscle stretching, or alveolar wall distortion. -
ANS✅✅Mechanical Receptors
The process where particles and bacteria get stopped as they enter the upper respiratory system by
nasal hairs and mucous. - ANS✅✅Filtration
Small particles sometimes make it pass filtration and make it down to the aveoli. An example is coal
dust which leads to... - ANS✅✅pneumoconiosis (black lung)
Mucous secreted -> particles stuck to mucous -> cilia that covers areas below the trachea to
bronchioles (so not in alveoli) beat and move mucous to mouth -> swallowed
This process is called... - ANS✅✅Mucociliary Clearance System
This is the bodies response to clear large and main airways. It is also considered a backup to the
Mucociliary Clearance System. - ANS✅✅Coughing
When the bronchi constrict in response to stimuli/particles trying to enter airway, it is called... -
ANS✅✅Reflex Bronchoconstriction
These are located in our alveoli and seek to phagocytize inhaled foreign particles. -
ANS✅✅Alveolar Macrophages
What can we do to promote surfactant secretion? - ANS✅✅Deep Breathing
What is subjective information? - ANS✅✅Info based on or influenced by personal feelings, tastes,
or opinions.
(ie. Pain, values, sexuality, self-perception, anything that cannot be measured)
What is a normal respiratory rate? - ANS✅✅12-20 for an adult, 16-25 for an older adult
