A group of students were discussing the integumentary system and the use of transdermal (TD) patches to administer medication. TD patches deliver a consistent dose of medication that diffuses at a constant rate through the skin into the bloodstream. Which student has the correct explanation?
1) Jonathan argued that the hand or foot would be the best place to apply the TD patch because it would have fewer layers to diffuse across to get to the blood supply in the dermis.

2) Gail stated that anywhere on the body other than the hands or feet would be better because the medication would only have four layers to diffuse across to get to the dermis where the blood vessels are located.

3) Kenneth argued that the hand and feet were not good because the sweating and use of the hands and feet would alter the adhesiveness of the patch so he recommended the other areas of the body place the patch.
