Answer to Question 1

ANS: B
Cranial nerve V, the trigeminal nerve, controls the sensation of the face and function of the masseter muscle. Cranial nerve VII, the facial nerve, controls facial expressions or motor function of the facial muscles. Cranial nerve III, the oculomotor nerve, controls the pupil and movement of eyes. Cranial nerve X is the vagus nerve, which is demonstrated by testing the gag reflex.

Answer to Question 2

ANS: B
The patient may provide the history of a more generalized rash developing 2 or more weeks following the primary lesion, which may still be evident. The primary lesion is usually an isolated, single red lesion, which ultimately ulcerates, forming a nontender chancre. There may be a period of malaise preceding the eruption of secondary lesions. These lesions vary in appearance and distribution, but the typical finding is of red maculopapular lesions smaller than 1 cm in diameter. Any portion of skin can be involved, including the scalp, mucous membranes, perineum, and the soles and palms. There is generalized lymphadenopathy.
