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

Answer and Explanation

Correct Answer : A,B,D,E

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 B

Explanation

A. Exhaling slowly after two seconds is not part of the incentive spirometer use. Proper technique involves a slow, steady inhalation, not exhalation.
B. Blowing forcefully into the mouthpiece indicates incorrect use of the spirometer. The client should inhale slowly and deeply through the mouthpiece to expand the lungs and improve ventilation.
C. Using a tight seal around the mouthpiece is correct and necessary to ensure that the spirometer measures the volume of air accurately.
D. Sitting upright during the treatment is correct as it maximizes lung expansion and facilitates deep breathing.

A. Increased oxygen saturation. B. Increased cough productivity. C. Decreased cough frequency. D. Decreased breath sounds.

Correct Answer is A

Explanation

A. Increased oxygen saturation indicates that the Venturi face mask is effectively delivering the specified concentration of oxygen. This is the primary goal of using a Venturi mask, which provides precise oxygen delivery to improve oxygen saturation levels.
B. Increased cough productivity is not a direct indicator of the effectiveness of a Venturi face mask. The mask's purpose is to deliver oxygen, not to alter cough patterns.
C. Decreased cough frequency is unrelated to the function of the Venturi face mask. The mask's effectiveness is measured by oxygen delivery rather than changes in cough frequency.
D. Decreased breath sounds are not a direct measure of the effectiveness of a Venturi face mask. Breath sounds could indicate other respiratory issues but do not specifically reflect the effectiveness of oxygen therapy.
