What factors are important in determining level of hypoxemia that the child may have experienced during the submersion? Select all that apply.
Oxygen concentration of the ambient air
Temperature of water
The weight of the child
The amount of time the child was submerged
Whether or not anyone witnessed the fall into the pool
Correct Answer : A,B,D
A. Oxygen Concentration of the Ambient Air
The oxygen concentration of the ambient air affects how much oxygen the child could have been exposed to once retrieved from the pool. If the child was submerged in water, the ability to access oxygen from the environment was compromised, which contributes to the level of hypoxemia experienced. Ambient air oxygen concentration is a crucial factor in determining how long it might take for hypoxemia to develop or improve after submersion.
B. Temperature of Water
The temperature of the water affects the child’s physiology during submersion. Cold water can lead to a more rapid decrease in core body temperature and can influence the child’s respiratory and cardiovascular responses, potentially affecting the degree of hypoxemia.
C. The Weight of the Child
The weight of the child does not significantly impact the level of hypoxemia experienced during submersion. While it might influence the child’s ability to stay afloat or the rescue process, it does not directly affect hypoxemia levels.
D. The Amount of Time the Child Was Submerged
The duration of submersion is a critical factor in determining the level of hypoxemia. Longer submersion times result in more significant oxygen deprivation and a greater degree of hypoxemia, which can impact the severity of respiratory and cardiac complications.
E. Whether or Not Anyone Witnessed the Fall into the Pool
While witnessing the fall might be relevant for understanding the context of the incident, it does not directly affect the level of hypoxemia experienced during the submersion. The key factors are related to the conditions and duration of the submersion itself

Correct Answer is A
Explanation
A. The upper torso is where the center of gravity shifts in elderly adults. As people age, their center of gravity moves higher due to changes in body composition and muscle strength, which can affect balance.
B. The feet are the base of support, not the center of gravity. The center of gravity is located higher up in the body.
C. The upper extremities do not represent the center of gravity. The shift in the center of gravity affects overall balance and stability.
D. The head does not represent the center of gravity; it is primarily located in the upper torso. The head's position influences balance but is not the center of gravity.
Correct Answer is B
Explanation
A. Isoniazid can cause side effects like peripheral neuropathy, but ringing in the ears is not a common symptom of this medication.
B. Gentamicin can cause ototoxicity, which includes symptoms such as ringing in the ears (tinnitus). This side effect is significant and should be reported to the healthcare provider for further evaluation.
C. Pyridoxine is used to prevent neuropathy caused by isoniazid and does not cause ringing in the ears.
D. Rifampin is an antitubercular medication but is not commonly associated with tinnitus as a side effect. The immediate concern with ringing in the ears is related to gentamicin.
