Answer to Question 1

Ans:
A

Feedback:

Emollients are fatty acid-containing lotions that replenish the oils on the skin surface but usually do not leave a residue on the skin. Humectants are the additives in lotions that draw out the water from the deeper skin layers and hold it on the skin surface. However, the water that is drawn to the skin is transepidermal water, not atmospheric water. Thus, continued evaporation from the skin can actually exacerbate dryness. Occlusive are thick creams that contain petroleum to act as a barrier. Lotions or cream additives include steroids or mild anesthetics, such as camphor, menthol, lidocaine, or benzocaine. These agents work by suppressing itching while moisturizing the skin.

Answer to Question 2

Ans:
A

Feedback:

Paget disease is a progressive skeletal disorder characterized by increasing structural changes of the long bones, spine, pelvis, and cranium; it usually begins during mid-adulthood. DDH is developmental dysplasia of the hip.
