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

Answer and Explanation

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 injury. 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 submersion.

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 submersion.
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 submersion.
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 D

Explanation

Step 1: Convert the child's weight from pounds to kilograms.

55 pounds ÷ 2.2 lbs/kg = 25 kg

Step 2: Calculate the total daily dose using the child's weight and the prescribed dosage.

25 kg × 150 mg/kg/day = 3750 mg/day

The nurse should administer 3750 mg of cefotaxime each day.

A. A 70-year-old female presents to the emergency department triage with a noticeable facial droop and garbled speech. B. A 70-year-old female presents to the emergency department triage with a noticeable facial droop and garbled speech. C. A 70-year-old female presents to the emergency department triage with a noticeable facial droop and garbled speech. D. After having a few drinks at a local seafood restaurant, the client’s husband noticed his wife’s speech became difficult to understand. E. 1915: Client arrives via personal car to the emergency department with facial drooping and garbled speech.

Correct Answer is ["A","B","C","E"]

Explanation

Choice A rationale:
The client’s presentation of a noticeable facial droop and garbled speech are classic symptoms of a stroke. These symptoms indicate that the brain is not receiving enough oxygen, which can lead to permanent damage if not treated immediately. Therefore, this client requires immediate health interventions.
Choice B rationale:
This choice is identical to Choice A. The client’s noticeable facial droop and garbled speech are indicative of a stroke and require immediate attention.
Choice C rationale:
This choice is also identical to Choices A and B. The client’s symptoms are indicative of a stroke, which is a medical emergency that requires immediate intervention.
Choice D rationale:
While the change in the client’s speech after having a few drinks at a restaurant could be due to alcohol consumption, it could also be a symptom of a stroke, especially when combined with a facial droop. However, this choice does not directly indicate the need for immediate health interventions as it lacks the specificity of the symptoms compared to Choices A, B, and C.
Choice E rationale:
The time of arrival and mode of transportation do not directly indicate the need for immediate health interventions. However, the mention of facial drooping and garbled speech upon arrival at the emergency department reinforces the urgency of the situation, as these are classic symptoms of a stroke. In conclusion, Choices A, B, C, and E all highlight data that indicate the client is in need of immediate health interventions due to potential stroke symptoms. It’s important to note that strokes require immediate medical attention to minimize brain damage and potential complications. Normal ranges for lab parameters would not apply in this scenario as it’s based on clinical observations rather than laboratory findings.
