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 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 B
Explanation
Choice A rationale:
Diarrhea and flatulence are common side effects of statin medications like lovastatin but are typically not considered emergencies. They may be managed with dietary adjustments or over-the-counter remedies.
Choice B rationale:
Muscle pain, especially if severe, requires the most immediate follow-up by the nurse. Muscle pain can be a symptom of a rare but serious side effect called rhabdomyolysis, which can lead to muscle breakdown and potential kidney damage. Prompt assessment and intervention are necessary if severe muscle pain occurs.
Choice C rationale:
Altered taste is a side effect of lovastatin but is generally not considered a medical emergency. It may affect the client's quality of life but does not require immediate follow-up.
Choice D rationale:
Abdominal cramps may occur as a side effect of lovastatin, but they are not typically considered an emergency. Like choice A, abdominal cramps can often be managed with dietary adjustments or over-the-counter remedies.
Correct Answer is B
Explanation
The correct answer is choiceb. Chest pain and dysrhythmia.
Choice A rationale:
Decreasing gastrointestinal (GI) cramping and nausea are not typical adverse effects of vasopressin.In fact, vasopressin can cause abdominal cramps and nausea as side effects.
Choice B rationale:
Chest pain and dysrhythmia are significant adverse effects of vasopressin.Vasopressin can cause vasoconstriction, leading to myocardial ischemia and arrhythmias.
Choice C rationale:
Vasodilation of the extremities is not an adverse effect of vasopressin.Instead, vasopressin typically causes vasoconstriction, which can lead to peripheral ischemia.
Choice D rationale:
Hypotension and tachycardia are not common adverse effects of vasopressin.Vasopressin is more likely to cause hypertension due to its vasoconstrictive properties.
