Answer to Question 1

ANS: C
Scabies is caused by the scabies mite. The inflammatory response and intense itching occur after the host has become sensitized to the mite. This occurs approximately 30 to 60 days after initial contact. In the previously sensitized person the response occurs within 48 hours. Edema, redness, and maceration are not observed in scabies.

Answer to Question 2

ANS: A
Itching is generally the only manifestation of pediculosis capitis (head lice). Diagnosis is made by observation of the white eggs (nits) on the hair shaft. Vesicles, scalp rash, and localized inflammatory response are not symptoms of head lice.
