ACCURATE QUESTIONS &ANSWERS. EXCELLENCE
GUARANTEED.
What are the types of pneumonia characterized in the learning objectives? Answer: Community-
acquired pneumonia, hospital-acquired pneumonia, and pneumonia in immunocompromised
people.
What is the significance of the tubercle bacillus in tuberculosis? Answer: It has unique
immunologic properties that differentiate primary tuberculosis from reactivated tuberculosis.
What are the two main types of lung cancer compared in the chapter? Answer: Small cell lung
cancer (SCLC) and non-small cell lung cancer (NSCLC).
Define the term 'paraneoplastic'. Answer: Paraneoplastic refers to symptoms or conditions that
are a consequence of cancer but not directly related to the tumor mass.
What are three paraneoplastic manifestations of lung cancer? Answer: Hypercalcemia, Cushing's
syndrome, and neurological syndromes.
What role does surfactant play in lung function in neonates? Answer: Surfactant reduces surface
tension in the alveoli, preventing collapse and aiding in lung expansion.
What is the cause and manifestation of Respiratory Distress Syndrome (RDS)? Answer: RDS is
primarily caused by surfactant deficiency in premature infants, leading to difficulty in breathing
and oxygenation.
What is bronchopulmonary dysplasia (BPD)? Answer: BPD is a chronic lung disease commonly
seen in premature infants, characterized by inflammation and scarring in the lungs.

,List the signs of impending respiratory failure in small children. Answer: Increased respiratory
rate, use of accessory muscles, retractions, and altered mental status.
What are the risk factors for COVID-19? Answer: Age over 60, underlying chronic conditions,
and immunocompromised status.
How is COVID-19 diagnosed? Answer: Diagnosis is typically made through PCR testing or
rapid antigen tests.
What are the common causes of respiratory tract infections? Answer: Viruses, bacteria,
mycobacteria, fungi, and opportunistic organisms.
What is the most frequent cause of respiratory tract infections? Answer: Viruses, particularly
rhinoviruses.
How do cold viruses spread? Answer: Primarily through hand contact and touching
contaminated surfaces, not through aerosol transmission.
What are the typical symptoms of the common cold? Answer: Dryness and stuffiness in the
nasopharynx, excessive nasal secretions, sore throat, and malaise.
What is the typical duration of a common cold? Answer: 3 to 7 days, with some lingering
symptoms lasting up to 2 weeks.
What is the recommended treatment for the common cold? Answer: Symptomatic treatment
with rest and antipyretic drugs; antibiotics are not effective.
What is the impact of respiratory infections on healthcare? Answer: They are a common reason
for physician visits, hospital admissions, and missed work or school days.
What demographic is particularly affected by pneumonia? Answer: Individuals over the age of
65 and children under the age of 5.
What is the global impact of tuberculosis? Answer: It affects over 10 million people and remains
one of the deadliest diseases worldwide.

, What are the common viral causes of the common cold? Answer: Rhinoviruses, parainfluenza
viruses, respiratory syncytial virus (RSV), and coronaviruses.
What is the role of the immune system in respiratory infections? Answer: A compromised
immune system increases susceptibility to severe respiratory infections.
What are the common fungal infections associated with lung infections? Answer:
Histoplasmosis, coccidioidomycosis, and blastomycosis.
What is the primary age group affected by RSV infections? Answer: Infants and children
younger than 6 years.
What are the clinical manifestations of a common cold? Answer: Nasal congestion, clear nasal
secretions, sore throat, and possible fever.
What is the significance of viral shedding in respiratory infections? Answer: Viral shedding can
occur shortly before and during the early days of symptoms, facilitating transmission.
What are common over-the-counter (OTC) remedies for the common cold? Answer:
Antihistamines and decongestants.
What is the primary action of antihistamines? Answer: They dry nasal secretions.
What side effects can antihistamines cause? Answer: Dizziness, drowsiness, and impaired
judgment.
What is a potential consequence of frequent use of antihistamines? Answer: Rebound
symptoms.
Do antihistamines shorten the duration of a cold? Answer: No, there is no evidence that they do.
What is the function of decongestant drugs? Answer: They constrict blood vessels in the swollen
nasal mucosa to reduce nasal swelling.
