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

 

 

ANS:   B

All socioeconomic groups are at risk for head lice infestation.

Humans are the only host for these obligate parasites, and infestation cannot be acquired through contact with pets or any other animals.

Head lice do not only affect people in crowded environments.

Head lice can be transmitted on clothing, hairbrushes, furniture, and other objects.

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.	transmission of body lice occurs by direct person-to-person contact.
b.	the treatment of skin surfaces will eradicate the infestation.
c.	all clothing and bedding must be disinfected.
d.	lice burrow into the body and require vigorous scrubbing to remove.

 

 

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 through 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.

4. A public health nurse is providing patient education for a patient who is being treated for scabies. The patient has been prescribed 5% permethrin (Elimite) cream to eradicate the scabies. What instruction about applying the cream should the nurse provide?

a.	“Apply daily from head to toe for 7 to 10 days.”
b.	“Massage in the cream, head to toe, once and wash off in about 12 hours.”
c.	“Apply once and rinse off in about 10 minutes.”
d.	“Shampoo into the hair and leave in place for 48 hours.”

 

 

ANS:   B

The nurse should instruct the patient to massage in the cream, head to toe, once and wash off in about 12 hours.

Permethrin cream should not be applied daily.

Permethrin cream should not be applied and rinsed in 10 minutes.

Shampooing the hair does not address the remaining body infestation.
