No immediate effect is observed

Explanation:

If you put ouabain, an inhibitor of the Na+-K + pump, on a neuron and then stimulate the neuron repeatedly, there would be no immediate effect to the action potentials generated by the neuron because Na + gets stucked inside the cell, the depolarization slope gets steeper, and the duration of the action potential shortens because the membrane potential reaches + 30 mV and other voltage-gated channels are opening in the membrane.
