Water Can Kill

Part 1 Questions

1. A hypotonic environment would be created around the cells causing them to swell. The movement of water located within the cells compartment because of the low osmolality of sodium

2. Jennifer and James both experienced nausea and vomiting, although the headache symptoms more than likely came from the brains limited capacity to swell before an edema occurs.

3. The cause of their immediate death was that with the nervous tissues being connected to the brain and the spinal cord it had to do with how quickly these three victims died.

4. To determine the underlying cause of hyponatremia, urine osmolality and urine sodium should be measured.

5. To give supplemental oxygen to patients with lethargy or obtundation. In these patients, evaluate the possibility of hypoglycemia with a rapid glucose check.

6. If they administered pure water, there is a very real risk of over hydrating the person which can also kill. The saline solution is supposed to be at the same concentration as what your body should be.

Part 2 Questions

1. Vasopressin makes athletes more vulnerable to hyponatremia because athletes retain a lot of water trying to stay hydrated while being active.

2. Desert dwellers are I danger of developing hyponoatrmia because they’re in the heat losing a lot of sweat and to gain back their water they drink more water. Hyponatrnia can be prevented by traveling in cooler places, and maintain sodium and water throughout the body fairly.

3. Infants and young children are at higher risk of developing hypothermia when exposed to the cold, because their bodies are less able to generate heat.

4.a) The normal amount of concentration solutes in your brain cells are 300mM.

b) I think that person would begin to feel the symptoms of dizziness and nausea also known as brain swelling.

C) 300mM- 280mM= 20mM so 1,200cm3 would become about 1,400cm3.
