Very few plants will kill with just one bite, and a goat's habit of nibbling a little of this and a little of that usually keeps them safe from poisons.
In evolutionary terms, it's not beneficial for a plant to be so poisonous as to kill browsers with one bite. That puts too much selective pressure on browsing herbivores to develop a resistance to the poison. It's much better for a plant to be just toxic enough to taste bad in small amounts, but only kill in larger amounts.
Rhododendron poisoning has as the early symptoms vomiting and nausea, which serve to lessen the amount ingested. I would not use activated charcoal as it may inhibit the vomiting response (which you would want in this situation). If the goat is looking poorly, I'd suggest milk of magnesia. If 2-3 hours go by and no symptoms, then you're probably in the clear. Alkaline plant poisonings (such as this) tend to show symptoms pretty fast.
One of my kid goats ate some milkweed a few weeks ago (one entire plant) and spent an hour projectile vomiting. By that evening you couldn't even tell anything had ever been wrong with him.
