Questions: A high school student developed allergic rashes all over her body after going on a camping trip. The student applied lidocaine spray to the affected area. Because of the spray she applied which of the following effects would be expected? A. Her rashes will decrease or resolve B. Infection will be cured C.Pruritus will decrease D. Her skin will be less dry

The answer is C: Pruritus will decrease.

Explanation for each option:

A. Her rashes will decrease or resolve - This is incorrect. Lidocaine is a local anesthetic that numbs the skin but does not treat the underlying cause of the rashes, such as an allergic reaction or inflammation.

B. Infection will be cured - This is incorrect. Lidocaine does not have antibacterial or antiviral properties, so it will not cure an infection.

C. Pruritus will decrease - This is correct. Lidocaine can help reduce itching (pruritus) by numbing the skin and providing temporary relief from the sensation of itching.

D. Her skin will be less dry - This is incorrect. Lidocaine does not have moisturizing properties and will not affect the dryness of the skin.

Summary: Lidocaine spray is expected to decrease pruritus (itching) by numbing the affected area, but it will not resolve rashes, cure infections, or make the skin less dry.
