EXAM WITH VERFIED QUESTIONS, DETAILED ANSWERS AND
RATIONALE FOR GRADED A+ SUCCESS
1.A 3-month-old infant diagnosed with bronchiolitis undergoes suctioning to remove
secretions from the upper airway. During the procedure, the infant's heart rate drops
significantly from 155 beats per minute to 65 beats per minute. Despite this bradycardic
event, the infant remains alert, has easily palpable pulses and exhibits a capillary refill time
of just 1 second, indicating good perfusion. In light of this situation, what is the most
appropriate initial intervention to address the infant's bradycardia while ensuring the
infant's safety and well-being?
A) Establish intravenous or intraosseous access and administer atropine at a dose of 0.02 mg/kg
intravenously to help increase the heart rate and improve cardiac output.
B) Establish intravenous or intraosseous access and administer epinephrine at a dose of 0.01
mg/kg intravenously to counteract the bradycardia and stimulate the heart rate.
C) Administer oxygen and ensure adequate ventilation while being ready to take further action if
the heart rate does not improve, closely monitoring the infant's response to oxygen therapy.
D) Call for assistance and prepare to provide transthoracic pacing or transvenous pacing as a
more immediate intervention for the significant bradycardia observed.
Correct Answer: C) Administer oxygen and ensure adequate ventilation while being
ready to take further action if the heart rate does not improve, closely monitoring the
infant's response to oxygen therapy.
Explanation:
In this scenario, the most appropriate initial intervention (C) Administer oxygen and ensure
adequate ventilation; be prepared to intervene further if the heart rate does not increase. Although
the heart rate has decreased to 65 beats per minute, the infant remains alert and demonstrates
good perfusion, as evidenced by palpable pulses and a capillary refill time of 1 second. Given
these indicators, the bradycardia may be related to the vagal response from suctioning rather than
a state of hypoperfusion. Therefore, administering oxygen and ensuring proper ventilation is
essential to support the infant's respiratory function. Continuous monitoring is critical, and
should the heart rate not improve, additional interventions can then be considered.

RATIONALE FOR GRADED A+ SUCCESS
2.A 15-year-old boy presents with sudden and severe respiratory distress characterized by
visible retractions and an alarming oxygen saturation level of 85%. Upon examination, the
trachea is found to be deviated to the right side and breath sounds are absent on the left,
indicating a potential respiratory emergency. His heart rate is elevated at 140 beats per
minute, his blood pressure is critically low at 84/60 mm Hg, and his capillary refill time is 3
seconds, suggesting poor perfusion. Given this clinical picture, what is the most appropriate
immediate intervention to address the boy’s condition?
A) Perform needle decompression on the left chest to relieve pressure from a suspected tension
pneumothorax.
B) Establish an intravenous line and administer 20 mL/kg of normal saline to manage
hypotension and improve perfusion.
C) Order a chest x-ray to assess the underlying cause of the respiratory distress and to rule out
conditions like pneumothorax or pleural effusion.
D) Insert a chest tube on the left side to facilitate drainage of air or fluid and reestablish normal
lung function.
Correct Answer: A) Perform needle decompression on the left chest to relieve pressure
from a suspected tension pneumothorax.
Explanation:
In this critical case, the most appropriate initial intervention is (B) Perform needle
decompression on the left chest. The presence of respiratory distress, tracheal deviation and
absence of breath sounds on one side suggests the likelihood of a tension pneumothorax, where
air trapped in the pleural space increases pressure and collapses the lung. This condition is life-
threatening and requires immediate intervention. Needle decompression is a rapid and effective
measure to release trapped air and allow the lung to re-expand. Once stabilized, further
management such as chest tube insertion can be considered to ensure proper drainage and
prevent recurrence. Thus, the priority is to alleviate the pressure in the thoracic cavity to restore
adequate respiratory function and improve oxygen saturation.
