b. Stratum corneum, stratum lucidum, stratum granulosum, stratum spinosum, stratum basale
c. Stratum basale, stratum granulosum, stratum spinosum, stratum corneum, stratum lucidum
d. Stratum basale, stratum spinosum, stratum granulosum, stratum lucidum, stratum corneum

When radiation is used to treat a nonmelanoma skin cancer, which of the following treatment techniques offers the best cosmetic effect?
a. Parallel-opposed high-energy photons
b. Single field low-energy photon
c. Single field low-energy electron
d. Interstitial brachytherapy
b. Single field low-energy photon
In instances where malignant melanoma is treated with radiation, delivering one fraction per day, which of the following is the most effective fraction size?
a. 100 to 150 cGy
b. 150 to 180 cGy
c. 180 to 200 cGy
d. 200 to 400 cGy
d. 200 to 400 cGy
Standard fraction sizes of 180 to 200 cGy are not effective. Larger doses per fraction are needed to overcome the apparent repair processes that melanoma cells seem to possess. Daily doses of 200 to 400 cGy or hyperfractionated doses of 115 cGy twice per day may be used.
Pigmentation following therapeutic doses of radiation is caused by which of the following?
a. Dwelling of capillaries of the dermal layer
b. Shedding of the epidermis
c. Increased production of melanin
d. Destruction of cells at the basal layer
c. Increased production of melanin
