The Nurse Is Assessing a Patient's Skin During an Office

The nurse is assessing a patient's skin during an office visit.What is the best technique to use to best assess the patient's skin temperature? Use the:

A) fingertips because they're more sensitive to small changes in temperature.
B) dorsal surface of the hand because the skin is thinner than on the palms.
C) ulnar portion of the hand because there is increased blood supply that enhances temperature sensitivity.
D) palmar surface of the hand because it is most sensitive to temperature variations because of increased nerve supply in this area.
