Quizplus · Accepted Answer

The epidermis is the outermost layer of the skin, followed by the papillary layer of the dermis, which is in direct contact with the epidermis. The reticular layer is the deeper layer of the dermis, and the hypodermic needle would not penetrate this layer unless it was inserted very deeply. Therefore, the correct order of skin layers that a hypodermic needle would penetrate is epidermis, papillary layer, and then reticular layer. This is represented by choice C.
