Question

A client is being treated for the ingestion of a neurotoxin that interferes with the depolarization phase of action potentials.

Answer 1

Answer:

The inflow of sodium ions.

Explanation:

The generation of the action potential requires the change in the membrane potential of the cell. This membrane potential is maintained due to the unequal distribution of the ions.

The cell potential of the cell is -70mV and maintained due to the presence of potassium ions. The depolarization occurs due to the influx of the sodium ions and results in the change in the membrane potential upto +30mV. The neurotoxin that interferes with depolarization process might affect the sodium ions uptake.

Thus, the answer is inflow of sodium ions.
