Answer to Question 1

ANS: B
Lyme disease occurs in people who spend time outdoors in May through September. The first disease state exhibits the distinctive bull's eye and a red macular or papular rash that radiates from the site of the tick bite with some central clearing. The rash spreads 5 cm or larger, and is usually in the axilla, midriff, inguinal, or behind the knee, with regional lymphadenopathy.

Answer to Question 2

ANS: D
Mobility and turgor are tested over the abdomen in an infant. Poor turgor, or tenting, indicates dehydration or malnutrition. The other sites are not appropriate for checking skin turgor in an infant.
