Burns
Only the epidermis is damaged; skin is red and swollen
First-degree
What percentage is one entire leg?
What is 18%
Sunlight helps the skin produce which vitamin.
What is Vitamin D?
A person has an abnormally low body temperature. Predict what happens to the dermal blood vessels and explain WHY.
What is they constrict to reduce heat loss?
A student develops an itchy, red rash exactly where a nickel bracelet touched the wrist. What is the most likely disorder?
What is Contact dermatitis?
Vaso means
What is Vessel?
A burn destroys the entire thickness of the skin and appears gray-white or black. What degree is it?
What is 3rd degree?
What percentage of an adult’s body is one entire arm?
What is 9%?
A patient loses a large amount of skin after a severe injury. Explain TWO ways this could interfere with homeostasi.
What is increased fluid loss, difficulty regulating temperature, increased infection risk, or impaired sensation.
When the body becomes too hot, do dermal blood vessels dilate or constrict?
What is Dilate?
Which fungal infection commonly affects the feet?
What is Athlete’s foot?
What is thermoregulation?
What is regulate and keep temperature stable or regulated?
Blisters are the BIG clue for which degree of burn.
What is 2nd degree?
An adult has burns covering the entire left arm and the entire anterior trunk. Calculate the TBSA ( total body surface area)
What is 9% plus 18%=27%
Name 4 types of sensory information detected by the skin.
What is touch, pressure, pain, and temperature?
Explain why dermal blood vessels constrict when a person is cold but dilate when a person is hot.
What is constriction reduces heat loss when cold; dilation allows more heat to be released through the skin when hot?
Identify BOTH disorders: Patient A has contagious bacterial sores that may become crusted. Patient B has chronic scaly plaques that are not contagious.
What is Patient A = Impetigo; Patient B = Psoriasis.
What does vasoconstriction?
What is vessels narrow?
Patient A has a second degree burns covering only over 30% of the body. Patient B has third degree burns over 12% of the the body. According to your review, which patient has a critical burn?
Both Second degree burns over 25% are critical, and third degree burns over 10% are critical.
An adult burns the entire anterior trunk. What percentage of TBSA is burned?
What is 18%?
Name any THREE of the five major functions of the skin.
What is Protection, regulating water loss, producing vitamin D, gathering sensory information, regulating body temperature?
What THREE responses can occur when the body becomes too cold?
What is shivering, goosebumps, and constriction of dermal blood vessels?
A patient has painful, pus-filled bumps developing around hair follicles. Identify the disorder AND its cause category.
What is Boils/carbuncles; bacterial?
What is hypothalamus and where is located?
What is located in the brain and receives information and responds?
Name the THREE major dangers of serious burns represented by D-E-C.
What is Dehydration , electrolyte imbalance, and circulatory shock.
An adult has full thickness burns covering the entire right leg, entire right arm, and head/ neck. Calculate the TBSA and classify the burn based on the description.
What is 18% + 9%+ 9%= 36%
A patient loses a large amount of skin after a severe injury. Explain TWO ways this could interfere with homeostasis.
What is increased fluid loss, difficulty regulating temperature, increased infection risk, or impaired sensation.
When the body becomes too cold, do dermal blood vessels dilate or constrict?
What is constrict?
A student develops an itchy, red rash exactly where a nickel bracelet touched the wrist. What is the most likely disorder?
What is contact dermatitis?
What is pathogen?
What is an organism that causes diseases?
Two patients have burns covering exactly 20% of their bodies. Patient A has 2nd degree burns and Patient B has 3rd degree burns. Which patient meets the percentage threshold for a critical burn? Explain.
Patient B 3rd degree burns are critical over 10%, while 2nd degree burns are critical over 25%.
A patient has 3rd degree burns covering only 8% of the body, so a student says, It isn’t critical because it’s under 10%. The burns involve the patients’s hand and face. Is the student correct?
No, even though the burn is below 10% TBSA, the study notes state that third degree burns involving face, hands, or feet are considered critical.
A severe injury destroys sensory receptors and blood vessels in the skin. Name TWO skin functions that would be directly affected.
What is gathering sensory information and regulating body?
Patient A is shivering with constricted dermal blood vessels. Patient B is sweating with dilated dermal blood vessels. Identify each patient’s likely temperature condition AND explain how each response helps restore homeostasis.
What is Patient A = hypothermia; constriction and shivering help conserve/produce heat. B = hyperthermia; sweating and dilation help release heat?
Three patients arrive at a clinic: one has recurring grouped blisters near the lips, another has contagious crusted sores, and the third has chronic scaly plaques that are not contagious. Diagnose all THREE and classify each cause.
What is Cold sores = viral; impetigo = bacterial; psoriasis = immune-related.
Does rash mean it’s an infection.
No
