PEARS - Pediatric Emergency Assessment, Recognition, and Stabilization Recognizing Respiratory Emergencies Questions and Answers 1 — Questions and Answers
Question 1: A 4-year-old child is brought to the clinic with a 'barking' cough, hoarseness, and inspiratory stridor. The child is alert, has no cyanosis, and mild intercostal retractions are visible. Based on the PEARS assessment, which type of respiratory emergency is most likely?
- Lower airway obstruction
- Lung tissue disease
- Upper airway obstruction (Correct answer)
- Disordered control of breathing
Correct answer: Upper airway obstruction
The classic presentation of a 'barking' cough, hoarseness, and inspiratory stridor points towards an issue in the upper airway. [18, 20] Croup is a common cause of these symptoms in young children and is a form of upper airway obstruction. [7, 18, 20] Lower airway obstruction typically presents with wheezing on expiration, lung tissue disease with crackles, and disordered control of breathing with an irregular respiratory pattern. [1, 7]
Question 2: Which of the following clinical signs is most indicative of a pediatric patient transitioning from respiratory distress to respiratory failure?
- Tachycardia and nasal flaring
- A significant decrease in respiratory rate and effort (Correct answer)
- Anxious appearance and intercostal retractions
- Loud, audible stridor or wheezing
Correct answer: A significant decrease in respiratory rate and effort
While tachycardia, nasal flaring, anxiety, retractions, and audible breath sounds are signs of respiratory distress, a significant decrease in respiratory rate and effort (bradypnea or inadequate breathing) is an ominous sign. [5, 8] It indicates the child is tiring and can no longer compensate, which is a hallmark of respiratory failure. [5, 8]
Question 3: You are assessing an 18-month-old who is lethargic with a rapid, shallow respiratory rate, grunting, and crackles heard on auscultation. These findings are most consistent with which category of respiratory problem?
- Lung tissue disease (Correct answer)
- Upper airway obstruction
- Foreign body airway obstruction
- Disordered control of breathing
Correct answer: Lung tissue disease
Grunting and crackles are characteristic signs of problems within the lung tissue itself, such as pneumonia or pulmonary edema. [1, 7] Grunting is an effort to keep alveoli open. [8] Upper airway obstruction presents with stridor, lower airway with wheezing, and disordered control of breathing involves an abnormal breathing pattern. [1, 7]
Question 4: A 6-year-old presents with sudden onset of respiratory distress while playing. The child is unable to speak, has a weak, ineffective cough, and you hear high-pitched inspiratory stridor. What is the most important initial step?
- Administer nebulized epinephrine
- Immediately begin chest compressions
- Encourage the child to cough forcefully
- Assess for severe airway obstruction and be prepared to provide relief maneuvers (Correct answer)
Correct answer: Assess for severe airway obstruction and be prepared to provide relief maneuvers
The sudden onset, inability to speak, and weak cough are signs of a severe (or complete) foreign body airway obstruction. The immediate priority is to recognize this and be prepared to deliver age-appropriate relief maneuvers (like abdominal thrusts for a child over 1 year). Encouraging coughing is appropriate for a mild obstruction, but not a severe one.
Question 5: Which of the following is a key differentiator between respiratory distress and respiratory failure in a pediatric patient?
- The presence of a cough
- The patient's level of consciousness (Correct answer)
- An elevated heart rate
- The presence of nasal flaring
Correct answer: The patient's level of consciousness
In respiratory distress, the child is compensating and is typically anxious but alert. [5] As the condition progresses to respiratory failure, inadequate oxygenation and ventilation affect brain function, leading to a decreased level of consciousness, such as lethargy, drowsiness, or unresponsiveness. [3, 5] While heart rate changes and signs of increased work of breathing (nasal flaring) are present in both, the change in mental status is a critical sign of failure. [5]
Question 6: A 2-year-old with a known neuromuscular disease is brought in with an irregular, shallow breathing pattern and periods of apnea. This presentation is most characteristic of which type of respiratory emergency?
- Lower airway obstruction
- Disordered control of breathing (Correct answer)
- Lung tissue disease
- Upper airway obstruction
Correct answer: Disordered control of breathing
Disordered control of breathing is characterized by an abnormal breathing pattern, such as irregular rate, shallow breathing, or apnea. [7] This is often caused by a problem in the central nervous system or with the nerves and muscles that control breathing, such as in neuromuscular diseases. [7, 19]
