Question

Which of the following statements related to "the bends" is(are) true? __________.

a) Increased water pressure due to increased depth causes more gases such as nitrogen to be dissolved in the blood.
b) As a diver ascends to the surface, the pH of body fluids increases.
c) Ascending too quickly causes nitrogen gas to come out of solution in body fluids, creating bubbles.
d) Nitrogen gas bubbles can clog blood vessels and lodge in joints and the nervous system.
e) Answers a, c, and d are true.
f) All of the above are true.

Answer 1

The correct statements related to "the bends" are: increased water pressure due to increased depth causes more gases such as nitrogen to be dissolved in the blood, ascending too quickly causes nitrogen gas to come out of solution in body fluids creating bubbles, and nitrogen gas bubbles can clog blood vessels and lodge in joints and the nervous system.

Step-by-step explanation:

The correct answer is e) Answers a, c, and d are true.

1. A) Increased water pressure due to increased depth causes more gases such as nitrogen to be dissolved in the blood. This is true because as a diver goes deeper underwater, the higher ambient pressure causes more gases to dissolve in their blood.
2. C) Ascending too quickly causes nitrogen gas to come out of solution in body fluids, creating bubbles. This is also true because when a diver ascends too quickly, the rapid decrease in pressure causes nitrogen gas to form bubbles in body fluids, resulting in decompression sickness.
3. D) Nitrogen gas bubbles can clog blood vessels and lodge in joints and the nervous system. This is true as well, as nitrogen bubbles can block blood vessels and cause pain and damage in joints and the nervous system.

Therefore, the correct answer is e) Answers a, c, and d are true.
