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 ["2"]
Explanation
Rationale: The nurse should calculate the dose based on the concentration of the medication. Since the suspension contains 500 mg of acetaminophen per 15 mL, a 1,000 mg dose requires 30 mL (2 tablespoons) of the suspension.
Correct Answer is A
Explanation
A) Correct- Electrolyte imbalances, particularly involving electrolytes like potassium, can lead to cardiac arrhythmias. Elevated blood pressure can strain the cardiovascular system, and mental status changes could indicate potential neurologic and cardiovascular involvement. Auscultating for an irregular heart rate helps identify any immediate cardiac issues that require intervention.
B) Incorrect- While monitoring sodium intake is important for clients with chronic kidney disease, it is not the most urgent action in this scenario. The presence of electrolyte imbalance, elevated blood pressure, and changes in mental status indicate a more acute concern that requires immediate assessment.
C) Incorrect- Documenting abdominal girth is relevant for assessing fluid status, but in this situation, the presence of electrolyte imbalance, elevated blood pressure, and mental status changes indicates a more critical issue that requires prompt intervention.
