I'm just a medical assistant, and I love reading medical blogs throughout the day. Figured I'd atleast give this a shot....

1) Seabather's Eruption

2)Do not rub skin, take antihistamine, apply hydrocortisone cream, shower with fresh water and apply soap, remove swim-suit asap, use ice pack to relieve pain, keep rash clean.

3) False

1. What is the cause of this patient's presentation?

-The patient was stung by a jellyfish

2. Name three treatments for this condition?

- Wash injury with either seawater, vinegar, or isopropyl alcohol. Remove tentacles with tweezers. Remove remaining nematocysts by shaving the area. Apply hydrocortizone cream 2-3 times a day. In severe cases, antivenin and airway support may be required (anaphylactic shock).

3. True or False: This condition can lead to cardiovascular collapse?

Answer by Zach at AMC
-True.

I won last time on a skin problem, so may as well try another....

1. Jellyfish sting
2. For skin reactions without other symptoms of a more severe reaction: Rinse wound with normal saline then soak in acetic acid or isopropyl alcohol; antihistamines; cold compresses.
3. Yes, but only species found in the South Pacific
