Integumentary Case Study
Chief Complaint: 28-year-old woman admitted for first
and second degree burns following her rescue from being lost in the
Mojave Desert for 72 hours.
History: Rachel McElravy, a 28-year-old white
female, was transported by an air ambulance to the emergency room
after wandering in the desert for 72 hours. She was doing research
in a remote part of the Mojave Desert when, she got lost in her
vehicle and had forgotten to bring her cell phone with her that
day. When her fuel run out, she walked and walked believing she
could find her way out. During the day, shade temperatures exceeded
110°F degrees with humidity levels at just 5%. When found, she had
developed severe facial and arm burns and was severely dehydrated.
Rachel’s core temperature was 101°F but she wasn’t
sweating!
In the hospital, Rachel was barley conscious,
weak, nauseated, suffering from headaches and had low blood
pressure of about 65/45. After administration of intravenous fluids
both in the ambulance and hospital, her vital signs
stabilized.
The next day Rachel had almost no pain on her
face and arms and couldn’t feel feather light touches to her burnt
face. This lasted for a few days. After further treatment of
antibiotics and surgery, Rachel was able to leave the hospital. She
possessed minor scars where she had been burnt. Slowly her
sensation of pain and touch returned to her skin.
Questions:
1. What
vitamin would Rachel have produced in greater quantity from her
ordeal?
2. What
condition did Rachel develop that lead her to not sweat despite the
elevated temperature?
3. Why was it
necessary to administer fluids to Rachel and what osmolarity did
they most likely administer?
4. Describe
her most likely distinct abnormal skin colouration of her face and
hands when they found (using technical terminology) Rachel in the
desert?
5. What
happened to cause Rachel to temporarily lose her sense of light
touch and pain within the burnt parts of her body? Which
cell/structures were affected in this loss?
6. What is
the difference between scar tissue and normal skin tissue? Why
where her scars minor.
7. Briefly
describe the two major layers that make up healthy skin?
8. What are
first-degree burns and second-degree burns? How many epidermal
strata did she lose in the areas of second degree burns.
9. Name four
cells associated with the skin and the injury that would be active
during her recovery process, include their functions.
