Correct Answer :Correct Answer: A,B,D
A. Oxygen Concentration of the Ambient AirThe oxygen concentration of the ambient air affects how
much oxygen the child could have been exposed to once retrieved from the pool. If the child was
submerged in water, the ability to access oxygen from the environment was compromised, which
contributes to the level of hypoxemia experienced. Ambient air oxygen concentration is a crucial
factor in determining how long it might take for hypoxemia to develop or improve after submersion.
B. Temperature of WaterThe temperature of the water affects the child's physiology during
submersion. Cold water can lead to a more rapid decrease in core body temperature and can influence
the child's respiratory and cardiovascular responses, potentially affecting the degree of hypoxemia.
D. The Amount of Time the Child Was Submerged. The duration of submersion is a critical factor in
determining the level of hypoxemia. Longer submersion times result in more significant oxygen
deprivation and a greater degree of hypoxemia, which can impact the severity of respiratory and
cardiac complications.
The client is a 2-year-old who fell in a pool. He was retrieved from the pool by a family member but was
not breathing. The family member started cardiopulmonary resuscitation (CPR) and the ambulance
brought him to the hospital.
Notes: The parents are at the bedside and inform that each parent thought the other parent was
watching the child. They are not sure how long he was in the pool or how he might have fallen in. The
temperature of the pool was as cool as the temperature outside, about 64° F (17.8° C).
Which are the first four actions that the practical nurse (PN) should do?
A: Take the child's pulse
B: Place a cervical collar on the client
C: Call child protective services
D: Start a peripheral IV line

E: Look for any open wounds
F: Determine if the child's airway is clear
- Correct Answer :Correct Answer: A, F, E
A- Assessing the pulse is crucial to determine if the child has a heartbeat and to evaluate the
effectiveness of CPR. This helps to determine the current cardiovascular status of the child and the
urgency of further resuscitation efforts.
F- Ensuring a clear airway is a priority in any emergency situation. A blocked airway can prevent
effective ventilation and oxygenation, which is critical for a child who has experienced a near-drowning
incident.
E- Checking for open wounds is necessary to identify any immediate sources of bleeding or potential
infections that need to be addressed. It is part of a thorough initial assessment to ensure
comprehensive care for the child.

lab: pH 7.31 (7.35-7.45)
PaCO2 51 (35-45)
Choose the most likely options for the information missing from the statement by selecting from the
lists of options provided. When the laboratory results are available, the practical nurse (PN) would
expect the child to have ______ related to ____ during the submersion. - Correct Answer :Dropdown
Group 1: Respiratory acidosis
Dropdown Group 2: Carbon dioxide retention
Respiratory acidosis. The laboratory results show a pH of 7.31, which is below the normal range of
7.35-7.45, indicating acidosis. Additionally, the PaCO2 is elevated at 51 mmHg, which is above the
normal range of 35-45 mmHg, pointing towards a respiratory cause of the acidosis.

Carbon dioxide retention. During the submersion, the child likely experienced impaired ventilation,
leading to hypoventilation and subsequent retention of carbon dioxide. This retention of CO2
contributes to respiratory acidosis.

not breathing. The family member started cardiopulmonary resuscitation (CPR) and the ambulance
brought him to the hospital.
What complications should the practical nurse (PN) monitor for in the next 6 to 8 hours? Select all that
apply.
A. Subdural hemorrhage
B. Respiratory distress
C. Hyperthermia
D. Cerebral edema
E. Acute asphyxia
F. Hypertension –
Correct Answer :Correct Answer: B,D,E
B- B. Respiratory distressGiven the history of drowning and the current signs of respiratory acidosis
(pH 7.31, PaCO2 51), the child is at high risk for respiratory complications, including distress.
D- Although the initial CT scan is negative for edema, secondary cerebral edema can develop hours
after the incident, especially in cases of significant hypoxemia.
E- The initial incident of drowning and the resultant hypoxemia (as indicated by abnormal blood gases)
place the child at risk for complications related to acute asphyxia.
