Answer to Question 1

A
Feedback:
Destruction with electrodesiccation (treatment with short duration, high-frequency electrical current) and curettage (scraping or suctioning) is the best treatment for common and filiform warts. Impetigo is treated with systemic antibiotics (e.g., dicloxacillin). A physician may carefully incise and drain large carbuncles after they come to a point. Application of the prescribed medication, such as lindane (Kwell), to the entire body from the neck down is the treatment of choice for scabies.

Answer to Question 2

D
Feedback:
In gram-negative bacteria, the murein layer is thin and is surrounded by an outer membrane. In this case, the stain is not retained and the organism looks light pink. In gram-positive bacteria, the cell envelope is a thick layer of murein and it retains the stain, turning a purple color.
