Acclimatization to heat can also help reduce the risk.

Question 12

What are common symptoms of hypothermia?

Answer 12

• Shivering
• Slurred speech
• Slow, shallow breathing
• Weak pulse
• Clumsiness

Hypothermia can progress rapidly and requires immediate warming and medical care.

Question 13

True or False:

Answer 16

Venom poisoning

Snake venom can cause tissue damage, disrupt blood clotting, and affect the nervous system.

Question 17

Fill in the blank:

When treating heat stroke, it’s crucial to ______.

Answer 17

rapidly cool the person

The most effective method for treating heat stroke is immersion in cold or ice water, if available. If immersion isn’t possible, apply ice packs to the neck, armpits, and groin and use cool, wet cloths or fans to reduce body temperature while awaiting emergency medical help.
