Severe burns, particularly third-degree burns that damage a significant portion of the body surface, can result in the release of sodium from damaged cells into the bloodstream leading to hypernatremia. Note: Words with the suffix '-emia' generally indicate a presence of a substance or condition in the blood. Question: Based on this information, which of the following statement/s is/are true? ☐ Hypernatremia would lead to a greater Na* influx through voltage-gated Na* channels. This increased Na* influx would cause the cell to reach threshold faster and increase cell excitability. ☐ Hypernatremia can result in more negative resting membrane potential due to the reduced efflux of Na+ ions. Consequently, this may lead to a decrease in the rate of action potential generation in excitable cells. Hypernatremia can result in a more positive resting membrane potential due to the increased influx of K+ ions. Consequently, this may lead to a decrease in the rate of action potential generation in excitable cells. 1 pts
