Question

How did you save Clark?

Answer 1

Answer:

3. Increase in blood sodium concentration

4. Net movement of free water into vessel

5. Decrease in matrix pressure

6. Decrease in neuron firing rate

7. Seizures stopped

Explanation:

Answer 2

Answer:

Since there are only two options listed and not much else, the correct order would be: first, the seizure happens and then you administer the hypertonic saline solution in order to stop the seizure and restore the correct balance.

Explanation:

This question comes from a more complete case where Clark suffers from cerebral edema due to an abnormal level of sodium (Na) which caused water imbalance to happen.

It must be remembered that the human brain works under a balance of water and electrolytes. One of which is sodium. In essence, where sodium goes, water goes. When sodium is in too low concentrations somewhere, the tendency is for the stores to go out to restore balance. Water will follow sodium as well.

In the case of Clark, because sodium was too high inside the tissues, then water leaked into those tissues to restore balance, causing the pressure around the brain to increase. Thus, as a form of protection, the brain seizes and shuts until the balance is restored. The hypertonic solution administered after the seizures has the purpose of increasing sodium in the blood so that water will move out of the tissues and back into the bloodstream.

This is why the correct order with the elements given by the question is 1. Seizures and 2. Administer hypertonic saline solution.
