The nurse is providing care to a client who has a vitamin D deficiency and is at risk for an alteration in skin integrity. The client states, "how can this be? I drink 3 glasses of milk each day."
Which response by the nurse is appropriate?
A) "A loss of melanin causes a decrease in vitamin D."
B) "The skin synthesizes vitamin D from sunlight."
C) "Insufficient protein intake causes a vitamin D deficiency."
D) "Not all milk contains vitamin D."
Answer: B
The skin performs several essential functions. One of these is the synthesis of vitamin D from ultraviolet light. If the client is not exposed to ultraviolet light, there is a risk for developing a vitamin D deficiency. In the United States cow's milk is fortified with vitamin D, and there is nothing to suggest the client is drinking another kind of milk. A loss of melanin does not lead to a decrease in vitamin D. Insufficient protein intake does not cause a vitamin D deficiency.
