2. A nurse is teaching a class at a community center on communicable diseases. Which statement by a member of the class best demonstrates understanding of the epidemiology of head lice?

a.	“All socioeconomic groups are at risk for this infestation.”
b.	“Head lice affect only people in crowded environments.”
c.	“Head lice are transmitted only by direct person-to-person contact.”
d.	“The infestation can be acquired from house pets.”

 

 

ANS:  A

All socioeconomic groups are at risk for head lice infestation. Head lice do not only affect people in crowded environments. Humans are the only host for these obligate parasites. Head lice can be transmitted on clothing, hairbrushes, furniture, and other objects. The infestation cannot be acquired through contact with pets or any other animals.

3. A public health nurse visits with the parents of a child who has body lice. It is most important that the nurse tell the parents that:

a.	body lice are transmitted by direct person-to-person contact.
b.	treatment of skin surfaces will eradicate the infestation.
c.	all clothing and bedding must be disinfected.
d.	lice burrow into the body, and vigorous scrubbing is required to remove them.

 

 

ANS:  C

The nurse should tell the parents that all clothing and bedding must be disinfected. In addition to person-to-person transmission, body lice can be acquired from clothing, furniture, bedding, rugs, and other items. Treatment of skin surfaces does not eradicate the infestation, because body lice reside mainly on clothing. Vigorous scrubbing is not required and may damage the skin.
