    Hyper resonance is found during percussion in a patient of Pneumothorax.

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    Hyperresonance is a characteristic finding during percussion in a patient with pneumothorax. This is because pneumothorax is a condition where air accumulates in the pleural space, causing the lung to collapse partially or completely. As a result, the affected lung becomes hyperinflated and resonates more intensely when percussed, leading to hyperresonance. Therefore, the statement "Hyperresonance is found during percussion in a patient of Pneumothorax" is true.

    A 44-year-old male came to the clinic with symptoms of breathlessness and cough. The chest X-ray revealed accumulation of dust-like particles in the lungs. He works as a labourer with a construction company. The possible diagnosis would be-

    • A.

      Emphysema

    • B.

      Pneumoconiosis

    • C.

      Bronchitis

    • D.

      Lung collapse

    Correct Answer
    B. Pneumoconiosis
    Explanation
    Based on the given information, the most likely diagnosis for the 44-year-old male with symptoms of breathlessness and cough, who works as a labourer with a construction company, would be pneumoconiosis. Pneumoconiosis is a lung disease caused by the inhalation of dust particles, often occurring in occupations with exposure to dust, such as construction work. The accumulation of dust-like particles in the lungs seen on the chest X-ray supports this diagnosis. Emphysema is a different condition characterized by the destruction of lung tissue, bronchitis is the inflammation of the bronchial tubes, and lung collapse refers to the partial or complete collapse of a lung, which do not align with the given symptoms and occupational exposure.

    Rate this question:

  • 15. 

    A 35-year-old female came with pleuritic chest pain, hemoptysis and cough. Chest X-ray revealed small tubercles in the lungs. The phlegm culture showed rod-shaped bacilli as the cause of the infection. The possible diagnosis is-

    • A.

      Tuberculosis

    • B.

      Pneumonia

    • C.

      Anthrax

    • D.

      Pulmonary consolidation

    Correct Answer
    A. Tuberculosis
    Explanation
    The correct answer is Tuberculosis. The patient's symptoms of pleuritic chest pain, hemoptysis, and cough, along with the presence of small tubercles in the lungs on chest X-ray, are indicative of tuberculosis. Additionally, the phlegm culture showing rod-shaped bacilli further supports the diagnosis of tuberculosis, as the bacteria responsible for this disease, Mycobacterium tuberculosis, are rod-shaped. Pneumonia and pulmonary consolidation may present with similar symptoms, but the presence of tubercles and specific bacilli in the culture point towards tuberculosis as the likely diagnosis. Anthrax is less likely in this case, as its symptoms and findings differ from those described.

    Rate this question:

  • 16. 

    Air taken into the lungs-

    • A.

      Breath

    • B.

      Breathe

    Correct Answer
    A. Breath
    Explanation
    The word "breath" refers to the air that is taken into the lungs during the process of breathing. It is the inhalation and exhalation of air, which is essential for sustaining life. "Breathe" is the verb form of "breath" and it describes the action of inhaling and exhaling. Therefore, "breath" is the correct answer as it specifically refers to the air taken into the lungs.

    Rate this question:

    Correct Answer
    B. Dose
    Explanation
    The word "Doze" is not a measure, but rather a verb meaning to sleep lightly. On the other hand, "Dose" refers to a specific quantity of medication or a substance that is prescribed or administered. Therefore, "Dose" is the correct answer as it aligns with the concept of a measure.

    Rate this question:

  • 21. 

    Breathing that takes place normally in the lungs are _______________ (vesicular/bronchial)

    Correct Answer
    vesicular
    Explanation
    Breathing that takes place normally in the lungs is referred to as vesicular breathing. Vesicular breath sounds are soft, low-pitched sounds heard during inspiration and expiration. These sounds are produced by the movement of air through the smaller airways and the alveoli in the lungs. On the other hand, bronchial breath sounds are louder and higher-pitched, and are heard over the larger airways. Therefore, the correct answer is vesicular.

    Rate this question:

  • 22. 

    Spitting of blood is ______________ . (hemoptysis/ hematemesis)

    Correct Answer

      Drug used to treat pneumonia

    • D.

      Tuberculin test (Purified Protein Derivative)

    Correct Answer
    D. Tuberculin test (Purified Protein Derivative)
    Explanation
    PPD stands for Purified Protein Derivative, which is a substance used in the Tuberculin test. The Tuberculin test is a diagnostic test used to determine if a person has been infected with the bacteria that cause tuberculosis. A small amount of PPD is injected under the skin, and if the person has been infected, a reaction will occur at the injection site. This reaction indicates that the person has been exposed to tuberculosis and further testing is needed to confirm the diagnosis. Therefore, the correct answer is Tuberculin test (Purified Protein Derivative).

    Rate this question:

  • 25. 

    Spasm and narrowing of the bronchi is _________________ (pertussis/ asthma).

    Correct Answer
    asthma
    Explanation
    Spasm and narrowing of the bronchi is a characteristic symptom of asthma. During an asthma attack, the muscles surrounding the airways tighten, causing the airways to become narrow and inflamed. This leads to difficulty in breathing, wheezing, coughing, and shortness of breath. Pertussis, on the other hand, is a highly contagious respiratory infection caused by the bacterium Bordetella pertussis, which primarily affects the upper respiratory system and does not cause bronchial spasms or narrowing. Therefore, the correct answer for this question is asthma.

    Rate this question:

  • 26. 

    Radioactive material is injected intravenously or inhaled during a/an-

    • A.

      MRI

    • B.

      CT scan

    • C.

      Lung scintiscan

    • D.

      Pulmonary angiography

    Correct Answer
    C. Lung scintiscan
    Explanation
    A lung scintiscan is a diagnostic test that uses radioactive material to create images of the lungs. The radioactive material is injected intravenously or inhaled by the patient. This allows the radioactive material to be distributed throughout the lungs, and the resulting images can help identify any abnormalities or diseases in the lung tissue. MRI, CT scan, and pulmonary angiography do not typically involve the use of radioactive material in the same way as a lung scintiscan.

      Asthma and Bronchiolytis

    • B.

      Bronchiectasis and Emphysema

    • C.

      Bronchitis and Emphysema

    • D.

      Bronchiolytis and Emphysema

    Correct Answer
    C. Bronchitis and Emphysema
    Explanation
    COPD, or chronic obstructive pulmonary disease, is a condition that affects the lungs and makes it difficult to breathe. It is typically caused by long-term exposure to irritants such as cigarette smoke. The correct answer, "Bronchitis and Emphysema," accurately identifies two of the main diseases that fall under the COPD umbrella. Bronchitis is the inflammation of the bronchial tubes, which carry air to the lungs, while emphysema is the damage to the air sacs in the lungs. Both conditions contribute to the narrowing of the airways and difficulty in breathing that is characteristic of COPD.

    • C.

      Adult Respiratory Distress Syndrome

    • D.

      Acidic Respiratory Distress Syndrome

    Correct Answer
    C. Adult Respiratory Distress Syndrome
    Explanation
    ARDS stands for Adult Respiratory Distress Syndrome. This condition is characterized by severe lung inflammation and fluid accumulation in the lungs, leading to difficulty in breathing. It is typically caused by injuries to the lungs, such as pneumonia, sepsis, or trauma. The term "adult" in ARDS differentiates it from a similar condition called neonatal respiratory distress syndrome, which affects newborns.

    Rate this question:

  • 31. 

    Collapse of the lung due to absence of surfactant leading to respiratory distress in new-born is termed as:

    • A.

      Pneumonia

    • B.

      Bronchiolytis

    • C.

      Hyaline Membrane Disease

    • D.

      Pneumonitis

    Correct Answer
    C. Hyaline Membrane Disease
    Explanation
    Hyaline Membrane Disease, also known as respiratory distress syndrome (RDS), occurs in newborns due to the absence or deficiency of surfactant, a substance that helps keep the lungs open. Without surfactant, the lung collapses, causing respiratory distress. This condition is characterized by the formation of a hyaline membrane lining the alveoli, which makes it difficult for oxygen to enter the bloodstream. Pneumonia, bronchiolitis, and pneumonitis are different respiratory conditions and not specifically related to the collapse of the lung due to surfactant deficiency.

    Rate this question:

  • 32. 

    Function of surfactant.

    • A.

      Gaseous exchange

    • B.

      Reduce the surface tension of the fluid lining the alveoli

    • C.

      Prevent lung patency

    • D.

      Leads to lung collapse

    Correct Answer
    B. Reduce the surface tension of the fluid lining the alveoli
    Explanation
    Surfactant is a substance that reduces the surface tension of the fluid lining the alveoli in the lungs. This reduction in surface tension helps to prevent the alveoli from collapsing and allows for easier gaseous exchange during respiration. By reducing the surface tension, surfactant allows the alveoli to remain open and maintain their shape, ensuring efficient exchange of oxygen and carbon dioxide between the lungs and the bloodstream.

    Rate this question:

  • 33. 

    The Hilum of the lung is situated in which surface?

    • A.

      Costal surface

    • B.

      Mediastinal surface

    • C.

      Diaphragmatic surface

    • D.

      Lung apex

    Correct Answer
    B. Mediastinal surface
    Explanation
    The hilum of the lung is the area where the bronchi, blood vessels, and nerves enter and exit the lung. It is located on the mediastinal surface of the lung. The mediastinal surface is the side of the lung that faces the mediastinum, which is the central compartment of the chest containing the heart, great vessels, and other structures. Therefore, the correct answer is "Mediastinal surface."

    Rate this question:

  • 34. 

    Intercostal muscles are the chief muscles of inspiration.

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    The statement "Intercostal muscles are the chief muscles of inspiration" is incorrect. The diaphragm is the chief muscle of inspiration, not the intercostal muscles. The diaphragm contracts and flattens during inhalation, increasing the volume of the chest cavity and causing air to be drawn into the lungs. The intercostal muscles, located between the ribs, assist in the expansion of the chest cavity during deep breathing but are not the primary muscles responsible for inspiration. Therefore, the correct answer is False.

    Rate this question:

  • 35. 

    Increased respiratory rate.

    • A.

      Bradypnea

    • B.

      Tachypnea

    • C.

      Dyspnea

    • D.

      Orthopnea

    Correct Answer
    B. Tachypnea
    Explanation
    Tachypnea refers to an increased respiratory rate. It is characterized by rapid breathing, usually exceeding the normal range of 12-20 breaths per minute. Tachypnea can be caused by various factors such as anxiety, fever, lung diseases, or metabolic disorders. The increased respiratory rate helps to compensate for the body's increased oxygen demand or to eliminate excess carbon dioxide. Therefore, tachypnea is the most appropriate term to describe an increased respiratory rate.

    • A.

      Mesothelioma

    • B.

      Pulmonary sarcoma

    • C.

      Mesotheliosarcoma

    • D.

      Pleurosarcoma

    Correct Answer
    A. Mesothelioma
    Explanation
    Mesothelioma is a type of malignant tumor that originates in the pleura, which is the thin membrane that lines the lungs and chest cavity. It is commonly caused by exposure to asbestos and can take several years or even decades to develop. Mesothelioma is a distinct form of cancer and is not classified as pulmonary sarcoma, mesotheliosarcoma, or pleurosarcoma, which are different types of tumors. Therefore, the correct answer is Mesothelioma.

    • C.

      Hepatitis

    • D.

      Bronchogenic Carcinoma

    Correct Answer
    B. Pneumocystits Carinii Pneumonia (PCP)
    Explanation
    Pneumocystis Carinii Pneumonia (PCP) is a fungal infection that is commonly seen in AIDS patients. HIV weakens the immune system, making individuals more susceptible to opportunistic infections like PCP. PCP affects the lungs and can cause symptoms such as cough, shortness of breath, and fever. It is a leading cause of illness and death in people with AIDS. Therefore, it is the most likely infection among the options given to be common in AIDS patients.

    The following refers to cough without phlegm or sputum:

    • A.

      Dry cough

    • B.

      Non-productive cough

    • C.

      Irritant cough

    • D.

      Whooping cough

    Correct Answer
    B. Non-productive cough
    Explanation
    A non-productive cough refers to a cough that does not produce any phlegm or sputum. This type of cough is often caused by irritation or inflammation in the respiratory tract. It is called non-productive because it does not help to clear the airways or remove any mucus. Non-productive coughs can be caused by various factors such as allergies, asthma, viral infections, or irritants in the environment. Treatment for a non-productive cough usually involves addressing the underlying cause and using medications to reduce inflammation and soothe the throat.

      Clubbing

    Correct Answer
    B. Raynaud's phenomenon
    Explanation
    Raynaud's phenomenon is characterized by a sudden spasm of peripheral arteries, leading to reduced blood flow to certain areas of the body, typically the fingers and toes. This reduced blood flow can cause the affected areas to become cold and numb. Therefore, Raynaud's phenomenon is the most appropriate explanation for the given symptoms of cold and numb skin areas.
