At the onset of a muscle contraction, the presence of calcium triggers the opening of the Na-K channels in the membrane. Potassium is a calcium inhibitor, so as the potassium flows out of the cell, it eventually reduces the presence of calcium. This causes the closure of the Na-K channel (negative feedback mechanism). In a hypokalemic state, the lack of sufficient K doesn't inhibit the calcium channel, and in turn doesn't properly terminate the muscle contraction at the cellular level.

prevent pain or dizziness, but this act isn't important. An emesis basin would
be used for irrigation of the ear. The client should be placed in the lateral
position for five minutes, not semi-Fowler's position, to prevent the drops
from draining.
