PEARS - Pediatric Emergency Assessment, Recognition, and Stabilization Managing Respiratory Emergencies Questions and Answers 1 — Questions and Answers
Question 1: A 4-year-old child presents with a sudden onset of high fever, muffled voice, drooling, and is sitting in a 'tripod' position. Which of the following respiratory emergencies is most likely?
- Croup
- Epiglottitis (Correct answer)
- Bronchiolitis
- Foreign body airway obstruction
Correct answer: Epiglottitis
The classic signs of epiglottitis are the '4 Ds': dysphagia (difficulty swallowing), dysphonia (muffled voice), drooling, and distress. The child often assumes a tripod position to maximize air entry. This is a life-threatening upper airway emergency.
Question 2: During the initial assessment of an infant, you observe nasal flaring, grunting, and significant subcostal retractions. These are signs of which type of respiratory problem?
- Mild respiratory distress
- Respiratory failure (Correct answer)
- Disordered control of breathing
- Compensated shock
Correct answer: Respiratory failure
Grunting is an ominous sign indicating the child is trying to maintain positive end-expiratory pressure to keep alveoli open. Combined with significant retractions and nasal flaring, these findings point towards respiratory failure, where the body can no longer compensate.
Question 3: Which of the following is the most appropriate initial intervention for a child with lower airway obstruction, such as asthma, who is in moderate respiratory distress?
- Administering a nebulized bronchodilator (Correct answer)
- Performing a blind finger sweep
- Applying cool mist to the face
- Preparing for immediate intubation
Correct answer: Administering a nebulized bronchodilator
Lower airway obstruction, commonly seen in asthma and bronchiolitis, involves bronchoconstriction. A nebulized bronchodilator like albuterol is a first-line treatment to open the airways and improve air exchange.
Question 4: A 2-year-old is brought in after being found with a small toy in their mouth. The child is now unable to speak or cough effectively and has stridor. What is the immediate priority in managing this patient?
- Encourage the child to cough forcefully.
- Attempt to visualize the object with a tongue depressor.
- Deliver age-appropriate back blows and chest thrusts. (Correct answer)
- Provide supplemental oxygen via a non-rebreather mask.
Correct answer: Deliver age-appropriate back blows and chest thrusts.
For a conscious child with a severe foreign-body airway obstruction (indicated by ineffective cough and stridor), the recommended intervention is to deliver repeated cycles of back blows and chest/abdominal thrusts until the object is expelled or the child becomes unresponsive.
Question 5: A 6-month-old infant presents with a runny nose, cough, and rapid, shallow breathing for two days. On examination, you hear widespread crackles and wheezing. This clinical picture is most consistent with which condition?
- Pneumonia
- Croup
- Lung tissue disease (e.g., bronchiolitis) (Correct answer)
- Disordered control of breathing
Correct answer: Lung tissue disease (e.g., bronchiolitis)
Bronchiolitis, a common lung tissue disease in infants, is characterized by inflammation of the small airways (bronchioles). This leads to symptoms like a preceding upper respiratory infection, tachypnea, and auscultatory findings of wheezing and crackles.
Question 6: In the PEARS systematic approach, which category of respiratory problem would be suspected in a child with an irregular breathing pattern, variable respiratory effort, and a known recent head injury?
- Upper airway obstruction
- Lower airway obstruction
- Lung tissue disease
- Disordered control of breathing (Correct answer)
Correct answer: Disordered control of breathing
Disordered control of breathing is characterized by an abnormal respiratory pattern due to a problem outside the lungs, such as a neurologic issue (e.g., increased intracranial pressure from a head injury), poisoning, or metabolic disturbance. The lungs themselves may be healthy.
