Midterm Exam 2025 ACTUAL TEST QUESTIONS & SOLUTIONS | 100% CORRECT |
ALREADY PASSED WITH A+!!
The ___ warms, humidifies, and filters air - upper airway
The ___ stops food from going into the trachea - epiglottis
The ___ is in charge of air conduction which allows cellular transport in the alveoli and produces
surfactant - Lower airway and tracheobronchial tree
___ are hair cells that line airway system which sweeps out bacteria and pathogens -
Mucociliary clearance
What population doesn't have mucociliary clearance? - Smokers
___ reduces the surface tension between the moist membranes and prevents alveoli from
collapsing - Surfactant
___ lobes are auscultated on the back of the patient - posterior
The ___ lobe is auscultated anteriorly - middle
The ___ is a thin layer of tissue that covers the lungs and lines the interior wall of the chest
cavity - pleura
The ___ makes pressure change easier in the lungs and allows them to expand and keeps them
'slippery' - Serous membrane
,The ___ pleura covers the lungs and the ___ pleura lines the thoracic cavity - Visceral; parietal
___ is the active phase of breathing and the diaphragm flattens and allows air to rush into the
lungs - Ventilation
___ is the passive phase of breathing when the diaphragm flattens and air moves out of the
lungs - Expiration
True or false: the thorax is a positive pressure space - False - its negative
Patients who have a change in surface area available due to water/fluid in the lungs - COPD,
chronic asthma pts
Factors influencing diffusion of gases in lungs - - change in surface area available (EX: edema)
- Thickening of alveolar capillary membrane (EX: chronic asthma)
- Partial pressure (EX: pressure change due to elevation and less oxygen, making alveolar less
expandable)
- Solubility and molecular weight of the gas (EX: smoke inhalation)
___ of the lungs can be altered by elevation. What does it do to the alveoli/ - partial pressure.
Makes alveoli less expandable
What type of patients have problems with solubility and molecular weight of the gas in the
lungs? - Burn patients and smokers
___ measures how accurately oxygen is carried in the body - Hemoglobin
What is oxygen carried in the body? - via plasma and RBC
, What are the RBC's that oxygen is carried called? - oxyhemoglobin
What are the RBC that carry CO2? - carboxyhemoglobin
___ is an inadequate amount of oxygen available to the cells - hypoxia
___ is difficulty breathing - dyspnea
In ___ the heart cells are dead and the damage is irreversible; whereas in ___ the cells still have
an opportunity to oxygenate - ischemia; hypoxia
When checking for hypoxia, what are the 2 places on a patient you should look at? - Nail beds
and gum lines
In patients with COPD, tissue swelling, asthma, and an excessive amount of secretions and
inflammation they are experiencing ___ - dyspnea - difficulty breathing
Patients with ___ use accessory muscle which looks like belly breathing - dyspnea
In ___ there is a decreased rate or depth of air movement into the lungs which may be caused
by giving patients too much narcotics - Hypoventilation
True or false: Some people may show no symptoms if they are having a heart attack and women
usually show less signs - True
___ is dead of cardiac tissue (myocytes) due to enough decreased oxygenation - Myocardial
ischemia
