HEARTCODE EXAM 4 2026 COMPREHENSIVE
STUDY GUIDE PRACTICE SET
◉ How is sniffing position achieved in an infant or a child? Answer:
Ensure that the external ear canal is anterior to the shoulder
◉ Where may padding be required under when properly positioning
a child older than 2 years of age to maintain a patent airway?
Answer: The occiput
◉ What actions are appropriate when providing 1-person bag-mask
ventilation? Answer: Perform a head tilt, insert an oral airway, &
squeeze the bag until chest rise
◉ What does the E-C clamp technique include? Answer: Using the
third, fourth, & fifth fingers of one hand along the jaw to lift it
forward
Using the thumb & index finger of the same hand to hold the face
mask
◉ When may a 2-person bag-mask technique be preferable?
Answer: When making a seal is difficult
When there is significant airway resistance
,◉ When suctioning a patient, which of the following should be
monitored? Answer: Clinical appearance
Oxygen saturation
Heart rate
◉ What should you do to help reduce the risk of hypoxemia during
suctioning? Answer: Limit suction attempts to 10 seconds or less
◉ Under what circumstance should you use an oropharyngeal
airway? Answer: The child must be unconscious
◉ What can happen if the oropharyngeal airway is too large?
Answer: It can block the airway
◉ When measuring for an oropharyngeal airway, it should extend
from the corner of the mouth to the angle of the [blank]. Answer:
Jaw
◉ The inspired oxygen concentration of a low-flow oxygen delivery
system is between [blank] % to [blank] %. Answer: 22
60
◉ The appropriate flow rate for a simple mask is [blank] to [blank]
L/min. Answer: 6
,10
◉ For a nonrebreathing mask to be effective, the oxygen flow rate
must be at least [blank] L/min. Answer: 10
◉ High-flow oxygen systems reliably deliver an oxygen
concentration of greater than [blank] %. Answer: 60
◉ The gas flow rate for a nebulizer treatment is [blank] to [blank]
L/min. Answer: 5
6
◉ What is an indication that a nebulizer treatment is complete?
Answer: No mist is visible
◉ When using a metered-dose inhaler [or MDI] w/ a spacer device,
what should you do? Answer: Shake the MDI & spacer vigorously
◉ When may pulse oximetry be inaccurate? Answer: The displayed
heart rate does not correlate with the child's heart rate
◉ When monitoring pulse oximetry in a child, what finding would
prompt immediate evaluation of the child? Answer: There is a
decrease in oxygen saturation
, ◉ Which are appropriate interventions for an apneic child? Answer:
Provide a breath every 2 to 3 seconds
Watch for chest rise
◉ Which of the following should be included in rescue breathing for
an infant? Answer: Use oxygen as soon as it is available
◉ When should the use of an endotracheal tube be considered in a
child? Answer: Child cannot maintain oxygenation despite initial
intervention
◉ What is the first step for an intubated child whose condition
deteriorates? Answer: Support oxygenation & ventilation
◉ What are the common causes of upper airway obstruction?
Answer: Airway swelling
Tonsillar hypertrophy
Thick secretions
◉ Which anatomical feature may contribute to upper airway
obstruction in infants? Answer: Large tongue
Large occiput
