Practice Indian Medical PG questions for Respiratory Diseases. These multiple choice questions (MCQs) cover important concepts and help you prepare for your exams.
Respiratory Diseases Indian Medical PG Question 1: A 2 years old child presents to PHC with fever and cough. He has chest in-drawing and respiratory rate of 38 per minute, weight 11 kg. The next step in management according to IMNCI is:
- A. Give antibiotics and re-assess in 3 days
- B. Refer to tertiary care
- C. Give antibiotics and refer to tertiary centre (Correct Answer)
- D. Only antipyretics are given
Respiratory Diseases Explanation: ***Give antibiotics and refer to tertiary centre***
- The child presents with **cough**, **fever**, and **chest in-drawing** with a respiratory rate of **38/minute**. According to **IMNCI guidelines**, the presence of **chest in-drawing** in a child aged 2 months to 5 years classifies the condition as **SEVERE PNEUMONIA**.
- For severe pneumonia, IMNCI protocol mandates **urgent referral to a hospital** where the child can receive injectable antibiotics (e.g., IV/IM ampicillin or ceftriaxone) and appropriate monitoring.
- The child should be given the **first dose of appropriate antibiotic** at the PHC level before referral to prevent deterioration during transport.
- This is the correct management approach combining immediate antibiotic therapy with necessary referral for severe disease.
*Give antibiotics and re-assess in 3 days*
- This management is appropriate for **simple pneumonia** (fast breathing without chest in-drawing), where oral antibiotics can be given at home with reassessment in 2-3 days.
- However, in the presence of **chest in-drawing**, the classification escalates to **severe pneumonia**, which requires hospital-level care with injectable antibiotics and monitoring, not outpatient management.
- Managing severe pneumonia at PHC without referral risks complications like respiratory failure, sepsis, or death.
*Only antipyretics are given*
- This is completely inadequate for a child with **severe pneumonia** (chest in-drawing).
- Fever management alone does not address the underlying **bacterial infection** requiring antibiotic therapy.
- This approach would lead to disease progression and potentially fatal complications.
*Refer to tertiary care*
- While referral is correct, giving the **first dose of antibiotic before referral** is a critical component of IMNCI protocol.
- Pre-referral antibiotic administration helps prevent deterioration during transport and initiates early treatment.
- Therefore, "give antibiotics AND refer" is more complete than referral alone.
Respiratory Diseases Indian Medical PG Question 2: Acute Respiratory Infections (ARI) are important causes of under-five mortality in India. In remote areas, children develop frequent episodes of ARI. What measures will you take for prevention and control of ARI amongst under-five children in that area?
- A. Vaccination
- B. Controlling malnutrition, Promoting breast feeding and vitamin A supplementation
- C. All of these (Correct Answer)
- D. Case management and Health education to mothers
Respiratory Diseases Explanation: ***All of these***
- Effective **prevention and control of Acute Respiratory Infections (ARI)** in under-five children requires a **comprehensive, multi-pronged approach** addressing multiple risk factors simultaneously.
- In **remote areas**, implementing all these interventions together provides the best outcomes for reducing ARI morbidity and mortality.
- This aligns with the **WHO/UNICEF Integrated Management of Childhood Illness (IMCI)** strategy that emphasizes combined preventive and curative measures.
**Why each component is essential:**
**Vaccination**
- Protects against major ARI pathogens including *Haemophilus influenzae* type b (Hib), *Streptococcus pneumoniae*, measles, and pertussis
- **Reduces both incidence and severity** of bacterial and viral respiratory infections
- Part of Universal Immunization Programme (UIP) in India
- Provides community-level protection through herd immunity
**Controlling malnutrition, Promoting breastfeeding, and Vitamin A supplementation**
- **Malnutrition** is a major risk factor for ARI severity and mortality (weakened immunity, impaired mucociliary clearance)
- **Exclusive breastfeeding for 6 months** provides passive immunity through maternal antibodies and protective factors (IgA, lactoferrin, lysozyme)
- **Vitamin A supplementation** strengthens epithelial barriers in respiratory tract and enhances immune response
- These nutritional interventions reduce **both susceptibility and severity** of ARI
**Case management and Health education to mothers**
- **Early case detection and appropriate treatment** (antibiotics for pneumonia, supportive care) prevents progression to severe disease and death
- Training mothers in **danger sign recognition** (fast breathing, chest indrawing, inability to drink) ensures timely healthcare seeking
- **Health education** covers environmental modifications (reducing indoor air pollution, avoiding smoking), hygiene practices, and appropriate home care
- Empowers community-level response in remote areas where healthcare access is limited
**Synergistic effect:**
- Prevention (vaccination, nutrition, breastfeeding) + Early detection and treatment (case management, health education) = **Maximum impact on ARI control**
- No single intervention alone can adequately address the complex epidemiology of ARI in resource-limited settings
Respiratory Diseases Indian Medical PG Question 3: A 15-month-old child presents with fever and cough since the last two days, the respiratory rate is 55/min and there is no drawing of the chest. According to the National Programme for Acute Respiratory Infections, the line of management should be
- A. Immediate referral of the child to hospital for urgent admission
- B. Administration of treatment for fever at home, advising the mother to return after two days for assessment of the need for an antibiotic
- C. Referral of the child to hospital for admission, after administration of first dose of antibiotic
- D. Administration of antibiotic at home along with treatment for fever, advising the mother to return for reassessment after two days (Correct Answer)
Respiratory Diseases Explanation: ***Administration of antibiotic at home along with treatment for fever, advising the mother to return for reassessment after two days***
- A respiratory rate of 55/min in a 15-month-old child indicates **fast breathing**, which is a sign of pneumonia. However, the **absence of chest indrawing** means it's classified as **non-severe pneumonia**.
- According to the National Programme for Acute Respiratory Infections (ARI) guidelines, **non-severe pneumonia** in children 2 months to 5 years without severe illness signs should be managed with **oral antibiotics at home** and outpatient follow-up.
*Immediate referral of the child to hospital for urgent admission*
- This action is indicated for **severe pneumonia** or **very severe disease**, characterized by signs such as chest indrawing, stridor, central cyanosis, or inability to drink, which are not present here.
- While the child has fast breathing, the **absence of chest indrawing** suggests a less severe presentation that does not immediately warrant urgent hospital admission.
*Administration of treatment for fever at home, advising the mother to return after two days for assessment of the need for an antibiotic*
- This approach is inappropriate because **fast breathing** is a definitive sign of pneumonia in this age group, requiring immediate antibiotic treatment.
- Delaying antibiotic administration could lead to the **progression of the infection** to a more severe form.
*Referral of the child to hospital for admission, after administration of first dose of antibiotic*
- Admission to the hospital is not required for **non-severe pneumonia** if the child can be managed at home and there are no signs of severe disease.
- The guidelines suggest home management with oral antibiotics unless specific **danger signs** for referral are present.
Respiratory Diseases Indian Medical PG Question 4: A child of 2 years having a respiratory rate of 46 per minute shall be classified by a health worker as
- A. no pneumonia, cough or cold
- B. severe pneumonia
- C. very severe disease
- D. pneumonia (Correct Answer)
Respiratory Diseases Explanation: ***Correct: Pneumonia***
- A respiratory rate of **46 breaths per minute** in a 2-year-old child falls within the criteria for **fast breathing**. According to World Health Organization (WHO) IMCI guidelines, fast breathing is defined as a respiratory rate ≥ 50 breaths/minute for children aged 2 months to 12 months, and **≥ 40 breaths/minute for children aged 12 months to 5 years**.
- Fast breathing alone (without chest indrawing or danger signs) is the **key clinical sign** for classifying a child with cough or difficulty breathing as having **pneumonia**.
- This is based on the **WHO IMCI classification** used by health workers for management of childhood illness.
*Incorrect: No pneumonia, cough or cold*
- This classification would be made if the child's respiratory rate was **within the normal range** for their age (< 40 breaths per minute for age 1-5 years) and if there were no other signs of pneumonia or severe disease.
- A respiratory rate of 46 breaths per minute in a 2-year-old is **above the normal limit** and meets the criteria for fast breathing.
*Incorrect: Severe pneumonia*
- Severe pneumonia is classified by the presence of **chest indrawing** in addition to cough or difficult breathing, without danger signs.
- While the child has fast breathing, the question does not mention **chest indrawing**, which is required for this classification.
*Incorrect: Very severe disease*
- Very severe disease is classified when there are **danger signs** present: inability to drink or breastfeed, persistent vomiting, convulsions, lethargy or unconsciousness, or stridor in a calm child.
- The question only mentions elevated respiratory rate without any **danger signs**, so this classification does not apply.
Respiratory Diseases Indian Medical PG Question 5: A 3-month-old baby presents with fever and respiratory rate of 60/min. The baby is irritable but feeding well. There is no stridor, no chest indrawing, and no convulsions. What is the diagnosis?
- A. Pneumonia (Correct Answer)
- B. Very severe pneumonia
- C. Severe pneumonia
- D. No Pneumonia
Respiratory Diseases Explanation: ***Pneumonia***
- A respiratory rate of 60 breaths per minute in a 3-month-old infant meets the **WHO criteria for fast breathing**, which is the primary indicator for diagnosing **pneumonia** in this age group.
- The absence of chest indrawing, stridor, or convulsions means this falls under **pneumonia**, not **severe** or **very severe pneumonia**.
*Very severe pneumonia*
- This would be diagnosed if there were **danger signs** such as inability to feed, lethargy, or convulsions, which are explicitly stated as absent.
- Presence of **stridor** in a calm child or **severe malnutrition** would also suggest very severe pneumonia, none of which are mentioned.
*Severe pneumonia*
- This classification requires the presence of **chest indrawing** or **stridor** in a child, which are noted as absent in the clinical presentation.
- While the child has fast breathing, the lack of additional severe signs distinguishes it from severe pneumonia.
*No Pneumonia*
- The presence of **fast breathing** (respiratory rate of 60 in a 3-month-old) is a clear sign of respiratory distress indicating **pneumonia**, according to WHO guidelines.
- If the child had a normal respiratory rate and no other signs of respiratory illness, this option might be considered.
