Question 24 TK01 - Tank Vessel Assistant - Dangerous Liquids

The Correct Answer is D **Explanation for Option D (An inadequate supply of oxygen):** Asphyxia is defined as a condition arising when the body is deprived of oxygen, causing unconsciousness or death. The underlying cause of asphyxia is a severe interruption or failure of the body's respiratory process, which prevents the uptake of oxygen (O₂) and/or the elimination of carbon dioxide (CO₂). Therefore, an inadequate supply of oxygen is the direct physiological cause of asphyxia. **Explanation for Incorrect Options:** **A) Improper caloric intake:** This relates to nutritional status and energy balance. While severe malnutrition can weaken the body, it does not directly cause the acute oxygen deprivation characteristic of asphyxia. **B) Too much oxygen:** This condition is known as hyperoxia. While excessive oxygen can be harmful (leading to oxygen toxicity), it is the opposite of the oxygen deprivation state that defines asphyxia. **C) Sleep deprivation:** This is a state resulting from inadequate rest. While severe sleep deprivation can impair cognitive and physical functions, it is not the cause of asphyxia, which is fundamentally a respiratory failure or obstruction leading to lack of oxygen.
