TOPIC 1: ASSESSMENT OF RESPIRATORY DISTRESS
7 Questions • 11.1% of Exam • This topic evaluates recognition and management of respiratory distress in children.
QUESTION 1
A 5-year-old child presents with lethargy, increased work of breathing, and pale color.
The primary assessment reveals that the airway is open and the respiratory rate is
30/min, with crackles heard on auscultation. The cardiac monitor shows sinus
tachycardia at a rate of 165/min. The pulse oximeter displays an oxygen saturation of
95% and a pulse rate of 93/min. On the basis of this information, which of the following
provides the best interpretation of the oxygen saturation of 95% by pulse oximetry?
[A] Reliable; no supplementary oxygen is indicated
[B] Reliable; supplementary oxygen should be administered
[C] Unreliable; no supplementary oxygen is indicated
[D] Unreliable; supplementary oxygen should be administered
Correct Answer: Unreliable; supplementary oxygen should be administered.
Rationale: The child's high respiratory rate and cardiac monitor reading indicate a high level of distress, suggesting that
their current oxygen saturation may not accurately reflect their actual oxygen status due to potential hyperventilation. This
implies that the pulse oximeter reading of 95% may not be reliable, making option D the correct answer.
QUESTION 2
Which of the following is a characteristic of respiratory failure?
[A] Inadequate oxygenation and/or ventilation
[B] Hypotension
[C] An increase in serum pH (alkalosis)
[D] Abnormal respiratory sounds
Correct Answer: Inadequate oxygenation and/or ventilation.
Rationale: Respiratory failure occurs when the lungs are unable to provide the body with adequate oxygen or remove
carbon dioxide efficiently, which directly relates to inadequate oxygenation and/or ventilation. This condition can be caused
by various factors, such as chronic obstructive pulmonary disease (COPD), pneumonia, or acute respiratory distress
syndrome (ARDS), and is often diagnosed through clinical assessments and laboratory tests.

QUESTION 3
Which of the following is most likely to produce a prolonged expiratory phase and
wheezing?
[A] Disordered control of breathing
[B] Hypovolemic shock
[C] Lower airway obstruction
[D] Upper airway obstruction
Correct Answer: Lower airway obstruction.
Rationale: Lower airway obstruction, such as that caused by asthma, is most likely to produce a prolonged expiratory phase
and wheezing because the obstruction in the lower airways prevents air from flowing out of the lungs quickly, resulting in a
prolonged expiration.
This prolonged expiration is accompanied by a high-pitched sound, or wheezing, as air tries to force its way through the
narrowed airways.
QUESTION 4
An alert 2-year-old child with an increased work of breathing and pink color is being
evaluated. Heart rate is 110/min, and respiratory rate is 30/min. What would best
describe this patient's condition?
[A] Respiratory distress
[B] Respiratory arrest
[C] Respiratory failure
[D] Disordered control of breathing
Correct Answer: Respiratory distress.
Rationale: The child's condition is characterized by an increased work of breathing, as indicated by a heart rate of 110/min
and a respiratory rate of 30/min, which suggests the body is working harder to breathe, but the child is still conscious and
able to maintain respiratory
efforts. This state of increased respiratory effort with a normal level of consciousness, rather than a lack of breathing or
failure to maintain adequate oxygenation, aligns with the definition of respiratory distress.
