At high altitudes, the partial pressure of oxygen in the air decreases, leading to a condition known as:

  1. Altitude sickness

  2. Hypothermia

  3. Frostbite

  4. Dehydration


Correct Option: A
Explanation:

Altitude sickness occurs due to the body's inability to adapt quickly to the reduced oxygen levels at high altitudes, leading to symptoms such as headache, nausea, and shortness of breath.

Which of the following is a common symptom of hypothermia, a condition caused by prolonged exposure to cold temperatures?

  1. Increased heart rate

  2. Sweating

  3. Shivering

  4. Dilated pupils


Correct Option: C
Explanation:

Shivering is an involuntary response of the body to generate heat and raise body temperature in cold conditions, helping to prevent hypothermia.

In cold weather, the body's blood vessels constrict to conserve heat, leading to a condition called:

  1. Hypothermia

  2. Frostbite

  3. Vasodilation

  4. Hyperthermia


Correct Option: B
Explanation:

Frostbite occurs when body tissues freeze due to prolonged exposure to cold temperatures, often affecting exposed areas such as fingers, toes, and ears.

Which of the following is a preventive measure to avoid altitude sickness during mountain climbing?

  1. Rapid ascent to the summit

  2. Adequate hydration

  3. Skipping meals before the climb

  4. Ignoring signs of altitude sickness


Correct Option: B
Explanation:

Adequate hydration is crucial to prevent altitude sickness, as it helps the body adjust to the reduced oxygen levels and maintain proper fluid balance.

In cold weather, the body's energy expenditure increases to maintain core temperature. This phenomenon is known as:

  1. Hypothermia

  2. Frostbite

  3. Vasodilation

  4. Thermogenesis


Correct Option: D
Explanation:

Thermogenesis refers to the body's increased production of heat to maintain a stable core temperature in cold environments.

Which of the following is a common symptom of dehydration, a condition caused by inadequate fluid intake?

  1. Headache

  2. Nausea

  3. Muscle cramps

  4. Increased urine output


Correct Option: A
Explanation:

Headache is a common symptom of dehydration, as the lack of fluids can lead to electrolyte imbalances and decreased blood volume, causing discomfort and pain.

In high-altitude environments, the body produces more red blood cells to compensate for the reduced oxygen levels. This physiological adaptation is known as:

  1. Hypoxia

  2. Polycythemia

  3. Vasodilation

  4. Hyperthermia


Correct Option: B
Explanation:

Polycythemia refers to the increased production of red blood cells in response to high-altitude conditions, helping to improve oxygen transport and delivery to tissues.

Which of the following is a recommended strategy to prevent frostbite in cold weather?

  1. Wearing loose-fitting clothing

  2. Exposing skin to cold air

  3. Avoiding sugary drinks

  4. Ignoring signs of frostbite


Correct Option: A
Explanation:

Wearing loose-fitting clothing allows for better air circulation and insulation, helping to prevent frostbite and maintain warmth.

In high-altitude environments, climbers often use supplemental oxygen to:

  1. Reduce the risk of altitude sickness

  2. Improve sleep quality

  3. Enhance athletic performance

  4. Prevent muscle cramps


Correct Option: A
Explanation:

Supplemental oxygen is used in high-altitude environments to increase the partial pressure of oxygen in the blood, reducing the risk of altitude sickness and its associated symptoms.

Which of the following is a common symptom of hypothermia, a condition caused by prolonged exposure to cold temperatures?

  1. Increased heart rate

  2. Sweating
