NUR 376 Exam 2 Study Questions with
Correct Answers
Compare and contrast the concepts of
ventilation, oxygenation, and perfusion. ✅ventilation is the process of moving air in and
out of the lungs
oxygenation involves adding oxygen to the blood in the lungs
perfusion: is the circulation of oxygenated blood to the body's tissues and organs.
Etiology:
Ventilation: respiratory muscle function and airway obstructions
Oxygenation: lung diseases and impairments in gas exchange.
Perfusion: cardiovascular disorders and blood flow abnormalities.
All are essential for maintaining adequate oxygen supply to the tissues and removal of
carbon dioxide.
- All are essential for maintaining adequate oxygen supply to the tissues and removal of
carbon dioxide.
- They are interrelated: Ventilation is necessary for proper oxygenation, and
oxygenation is crucial for perfusion.
- Abnormalities in any of these concepts can lead to impaired gas exchange and tissue
hypoxia.
Describe the various types of pneumonia, the
risk factors, prevention and treatment options ✅Pneumonia is an infection that
inflames the air sacs in one or both lungs, causing them to fill with fluid or pus.
Bacterial pneumonia: Common bacteria that can cause pneumonia include
Streptococcus pneumoniae (pneumococcus), Haemophilus influenzae, and Legionella
pneumophila. Bacterial pneumonia can range from mild to severe and is often
characterized by sudden onset of symptoms.
Viral pneumonia: Viruses such as influenza (flu), respiratory syncytial virus (RSV), and
the novel coronavirus (COVID-19) can cause viral pneumonia. Viral pneumonia is
usually milder than bacterial pneumonia but can still be serious, especially in vulnerable
populations.
,Fungal pneumonia: Fungal pneumonia is typically seen in individuals with weakened
immune systems, such as those with HIV/AIDS or those undergoing chemotherapy.
Fungal pathogens, like Candida or Aspergillus, can cause pneumonia in these
individuals.
Aspiration pneumonia: This type of pneumonia occurs when foreign substances, such
as food, saliva, or vomit, are inhaled into the lungs. It is often caused by swallowing
difficulties, impaired consciousness, or conditions like GERD (gastroesophageal reflux
disease).
Risk factors:
Age: Infants, young children, and older adults are more susceptible.
Weakened immune system: People with HIV/AIDS, undergoing chemotherapy, or taking
immunosuppressive drugs are at higher risk.
Chronic lung diseases: Conditions like COPD or asthma increase the risk.
Smoking: Smoking damages the lungs and impairs the immune system.
Hospitalization: Being in a hospital, especially on a ventilator, increases the risk of
pneumonia.
Aspiration: Swallowing difficulties or impaired consciousness can lead to aspiration
pneumonia.
Prevention:
Vaccination: Vaccines are available for certain types of pneumonia, such as
pneumococcal pneumonia and influenza.

What is pneumonia? ✅Pneumonia is inflammation in the lungs where air spaces fill
with infection-fighting cells and fluid. Bacteria or viruses are the main culprits, but it can
also happen due to inhaling chemicals, swallowing substances from the throat or
stomach, or infection by other microorganisms like fungi and rickettsiae.
Types of Pneumonia ✅Community-acquired pneumonia (CAP): Streptococcus
pneumoniae (pneumococcus); H. influenzae, Mycoplasma, Klebsiella, Staphylococcus,
and Legionella (spread via water) and gram-negative organisms.
Hospital-acquired pneumonia (HAP): Staphylococcus; methicillin-resistant
Staphylococcus aureus (MRSA); Pseudomonas, Klebsiella, and Acinetobacter
Ventilator-associated pneumonia (VAP): Enterococcus; Pseudomonas, Klebsiella, and
Acinetobacter
Aspiration pneumonia: anaerobic bacteria swallowed from the oropharynx.
Risk Factors for Pneumonia (etiology): ✅Bacteria are the most common cause of
pneumonia, and different types of pneumonia are associated with specific conditions
and settings.
,Streptococcus pneumoniae is the main culprit for community-acquired pneumonia
(CAP), while other pathogens like H. influenzae, Mycoplasma, Klebsiella,
Staphylococcus, Legionella, and gram-negative organisms can also be involved.
Aspiration pneumonia is often caused by anaerobic bacteria from the throat, while
certain pathogens like Staphylococcus can spread to the lungs through the
bloodstream.
Influenza infection is a major risk factor for pneumonia, as it weakens the lung's
defenses and makes it susceptible to secondary bacterial infections.
Immunosuppression, aspiration, and certain medical conditions like COPD and lung
cancer also increase the risk.
Emerging infections and environmental sources of pathogens can cause pneumonia,
such as Legionella and bioterror agents like Bacillus anthracis (anthrax).
Prevention of Pneumonia: ✅The pneumococcal vaccine is recommended to prevent
pneumonia in older adults, infants, and children at risk.
Treatment Options for Pneumonia: ✅antibiotics and providing oxygen
The patient should be positioned in Fowler's position and given oxygen through a nasal
cannula or mask.
IV fluids may be necessary if the patient is dehydrated.
pain relief, fever-reducing medications, and bronchodilators
Identify the basic pathophysiologic concepts of
respiratory function.: Atelectasis ✅Atelectasis, the collapse of alveoli in the lungs, is
common after surgery and increases the risk of pneumonia. To treat atelectasis,
patients are encouraged to cough, take deep breaths, and use an incentive spirometer.
This helps open up the collapsed alveoli and maintain lung health.
Understand the etiology of select inflammatory
upper airway disorders. ✅Respiratory tract infections impact breathing patterns and
airway clearance by altering the production and nature of secretions in the airways. Risk
factors for these infections include stress and exposure to individuals carrying different
microorganisms like bacteria, viruses, and fungi. Conditions that weaken the immune
system enable microorganisms to invade the body and rapidly multiply, potentially
leading to infection.
There are over 200 virus strains responsible for upper respiratory tract infections. The
primary mode of viral transmission is through airborne droplet nuclei released when an
, infected person coughs, laughs, or sneezes. Pathogens can also be spread through
direct hand-to-hand contact.
inflammatory
upper airway disorders. ✅Acute Rhinitis
Acute Pharyngitis
Acute Sinusitis
Acute Tonsillitis
Epiglottitis
Laryngitis and Tracheitis
Acute rhinitis ✅Acute rhinitis (common cold/ Flu) -- inflammation of the nasal passages
caused by a viral infection.
Etiology: primarily viral, with respiratory viruses being the main cause of inflammation in
the nasal passages.
Acute Pharyngitis ✅Acute pharyngitis (sore throat)
-inflammation of the pharynx (back of the throat)
Etiology: viral, bacterial infections, irritants or allergens; Environmental factors: dry air,
smoking, exposure to pollutants, or excessive voice strain can lead to throat irritation
and inflammation.
Acute sinusitis ✅Acute sinusitis (sinus infection)
- inflammation of the sinus cavities caused by viral infections, bacterial infections, or
allergies.
Etiology: viruses infect the nasal passages and lead to inflammation and blockage of
the sinus openings. This blockage prevents proper drainage of mucus, causing it to
accumulate in the sinuses and promoting bacterial growth.
Acute Tonsillitis ✅Acute tonsillitis (inflammation and infection of the tonsils)
- Viral and Bacterial infection
Etiology: Streptococcus bacteria, allergies or chronic tonsillar enlargement contribute to
the development or persistence of tonsillitis.
Epiglottitis ✅Epiglottitis
- inflammation and swelling of the epiglottis, a flap of tissue located at the base of the
tongue that covers the opening of the windpipe during swallowing.
Etiology: Bacterial infection: Streptococcus pneumoniae or Streptococcus pyogenes
(group A Streptococcus), Haemophilus influenzae type B (Hib), invade and infect the
epiglottis, leading to inflammation and swelling.
Viral Infections: influenza, parainfluenza, or herpes
