Tetrodotoxin blocks voltage-gated sodium channels, and ouabain blocks sodium-potassium pumps. If you added both tetrodotoxin and ouabain to a solution containing neural tissue it will result in immediate loss of action potential with gradual shift in resting potential.

When the voltage gated sodium channels are blocked then any threshold would not be able to cause an action potential thus, there will be an immediate loss of action potential and any depolarization step.

Moreover, when sodium potential pumps are blocked there is no influx or out flux of sodium or potassium ions thus the concentration of ions inside increases resulting in the gradual shift in resting potential.
