PEARS - Pediatric Emergency Assessment, Recognition, and Stabilization Recognizing Respiratory Emergencies 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?

Accepted Answer

Upper airway obstruction

Answer

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?

Accepted Answer

A significant decrease in respiratory rate and effort

Answer

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?

Accepted Answer

Lung tissue disease

Answer

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?

Accepted Answer

Assess for severe airway obstruction and be prepared to provide relief maneuvers

Answer

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?

Accepted Answer

The patient's level of consciousness

Answer

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]
