Question 11 of 35

That answer is incorrect. This statement is true.

The concentrations found in topical anesthetics are usually greater than if that same agent were administered by injection. That is because a higher concentration is needed for the active ingredients to diffuse through the mucous membranes.

This quick diffusion to the nerve endings helps with a faster onset of the topical anesthetic. This, however, can lead to a greater potential for toxicity not only topically, but also systemically.
