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
Gravida: The client has been pregnant five times: three times she gave birth to term babies, once she gave birth to preterm twins, and once she had a spontaneous abortion.
Term births: She has given birth three times: at 38 weeks, 41 weeks, and 35 weeks (twins). These are all considered term births. Term pregnancies are 37 weeks and beyond. So, the number of term births is 2.
Preterm births: She had one birth at 35 weeks, which is considered preterm. So, the number of preterm births is 1.
Abortions: She had one spontaneous abortion at 10 weeks' gestation. So, the number of abortions is 1.
Living children: All of her children are alive and well. So, the number of living children is 4.
Correct Answer is C
Explanation
A) Incorrect- While understanding the frequency that a problem occurs can provide context to its significance and potential impact, it is not the most important consideration when gathering evidence for evidence-based decision-making. The frequency alone does not ensure that the evidence collected will be directly applicable to the current situation.
B) Incorrect- Personal values are subjective and may influence an individual's perspective, but they are not the primary consideration when gathering evidence for evidence-based decision- making. Evidence-based practice aims to rely on objective and scientifically validated information rather than personal values, which can vary greatly among individuals.
C) Correct- The most important consideration when gathering evidence is its relevance to the specific situation at hand. Evidence must directly address the problem and clinical question, ensuring that the information collected is applicable, appropriate, and reliable for guiding decision-making in the current context.
D) Incorrect- While past experiences can offer insights, they are not the most important consideration for evidence-based decision-making. Relying solely on past experiences may not account for new developments, changing guidelines, or unique aspects of the current situation that were not present in previous encounters.
