The child is a 2-year-old who fell into a pool. He was retrieved from the pool by a family member but was not breathing. The family member started CPR, and the ambulance brought him to the hospital.
What factors are important in determining the level of hypoxemia that the child may have experienced during the submersion?
Select all that apply.
Temperature of water
The weight of the child
Oxygen concentration of the ambient air
Whether or not anyone witnessed the fall into the pool
The amount of time the child was submerged
Correct Answer : A,E
The level of hypoxemia that the child may have experienced during the submersion depends on several factors, but the most important ones are:
- The **temperature of water**: Cold water can induce a diving reflex, which lowers the heart rate and oxygen consumption, and may protect the brain from hypoxic injury¹². Cold water can also cause laryngospasm, which prevents water aspiration but also impairs gas exchange.
- The **amount of time the child was submerged**: The longer the submersion, the more severe the hypoxemia and the higher the risk of brain damage and death. The survival rate decreases significantly after 5 minutes of submersion³.
The other factors are less relevant or not directly related to the level of hypoxemia:
- The **weight of the child**: This may affect the buoyancy and the ability to float or swim, but not the oxygen consumption or gas exchange during submersion¹.
- The **oxygen concentration of the ambient air**: This may affect the pre-submersion oxygen saturation, but not the rate of oxygen depletion or gas exchange during submersion¹.
- The **witnessing of the fall into the pool**: This may affect the time to rescue and resuscitation, but not the level of hypoxemia during submersion.

Correct Answer is B
Explanation
This is the observation that indicates that the UAPs need additional information about the turning procedure because it is incorrect and may cause complications for the client. The client who had a hip arthroplasty with prosthesis placement should not keep both legs straight and together while turning because this may cause dislocation of the prosthesis, nerve damage, or bleeding. The client should keep the affected leg slightly abducted and supported with pillows or an abduction device.
Correct Answer is C
Explanation
A) Incorrect- an audible voice when client is trying to communicate, indicates that the client has some air passing through the vocal cords, which may be due to a partially deflated cuff or a speaking valve. This is not a life-threatening situation, but the nurse should ensure that the cuff pressure is adequate and that the client is not experiencing any discomfort or aspiration risk.
B) Incorrect- This may indicate atelectasis, pneumonia, or pleural effusion in that lung area. The nurse should auscultate the client's lungs more thoroughly, monitor the client's oxygenation and ventilation parameters, and report the findings to the provider.
C) Correct- This finding suggests that the client may have a ventilator disconnect, a leak in the circuit, or a cuff leak, which can compromise the client's oxygenation and ventilation. The nurse should immediately check the ventilator connections and tubing, and assess the client's vital signs and oxygen saturation.
D) Incorrect- high-pressure alarm sounds when the client is coughing, which is a common occurrence in mechanically ventilated clients who have increased airway resistance due to secretions, bronchospasm, or coughing. The nurse should suction the client as needed, administer bronchodilators if prescribed, and ensure that the ventilator settings are appropriate for the client's condition.
