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 A
Explanation
Rationale for A: Elevated energy level is a common effect of cocaine use, but it does not encompass the full range of behaviors associated with the drug's effects.
Rationale for B: Powerful cravings for more cocaine can develop over time, especially after the initial effects wear off, but they are not the immediate behavior observed.
Rationale for C: High self-esteem may be a temporary effect, but it does not specifically indicate current behavior associated with cocaine use.
Rationale for D: Euphoria is one of the primary effects of cocaine and is typically experienced shortly after use. This intense feeling of pleasure is a hallmark behavior observed in clients who have recently used cocaine.
Correct Answer is D
Explanation
A) Incorrect- This response might address the client's concern but doesn't directly address her dichotomous thinking or provide immediate therapeutic communication.
B) Incorrect- While showing happiness for the client's improvement is positive, this response does not address the client's behavior or engage with her dichotomous tendency.
C) Incorrect- This response acknowledges the client's liking but doesn't address the dichotomous thinking pattern or provide an effective therapeutic response.
D) Correct- answering this question encourages the client to express her concerns and perceptions, fostering communication. This approach acknowledges the client's feelings and provides an opportunity for her to discuss the issue, potentially leading to a productive conversation.
