Question 1

Which of the following make up the major components of the integumentary system?

Accepted Answer

B

Question 2

What is the main function of the acid mantle?

Accepted Answer

The acid mantle is a very thin, acidic film on the surface of the skin that acts as a barrier to bacteria, viruses, and other potential contaminants that might penetrate the skin. It is composed of sebum (from sebaceous glands) mixed with lactic and amino acids (from sweat) to create the skin's pH, which ranges from 4.5 to 6.2. This acidic environment helps to inhibit the growth of harmful bacteria and fungi, maintaining the balance of the skin's microbiome and preserving skin integrity.

Question 3

The functions of the skin include:

Accepted Answer

The skin serves multiple vital functions including protection (from environmental hazards), sensation (enabling the sense of touch), and absorption (allowing transdermal delivery of medication and absorption of vitamin D). Respiration and red cell production are not functions of the skin.

Question 4

What is the name of the cells of the skin that protect the body from infection by mounting an immune response?

Accepted Answer

Langerhans cells are a type of dendritic cell found in the skin and mucosa that serve as antigen-presenting cells, playing a crucial role in the skin's immune defense by recognizing pathogens and initiating an immune response.

Question 5

George has been admitted to intensive care with smoke inhalation following a house fire. He has sustained 50% third degree and 20% second-degree burn injuries to his skin.
-The loss of skin will leave George prone to ______

Accepted Answer

The loss of skin due to burns leaves the body vulnerable to significant heat loss because the skin acts as a thermal regulator, infection due to the breach in the body's primary defense mechanism against external pathogens, and pain due to exposed nerve endings.

Question 6

George has been admitted to intensive care with smoke inhalation following a house fire. He has sustained 50% third degree and 20% second-degree burn injuries to his skin.
-When calculating the extent of the burn, what method would you use?

Accepted Answer

The Wallace Rule of Nines is used to estimate the total body surface area affected by burns, making it the appropriate method for assessing the extent of burn injuries like those described for George.

Question 7

Freda has been admitted to intensive care and has had prolonged sedation and ventilation. She has been fed via a nasogastric tube. She has suffered from diarrhoea for some time and there is erythema around her perineal area.
-What is this called?

Accepted Answer

Incontinence Associated Dermatitis (IAD) is the correct term for skin damage and erythema caused by prolonged exposure to stool or urine, which is likely in Freda's case due to her diarrhoea and immobility.

Question 8

Freda has been admitted to intensive care and has had prolonged sedation and ventilation. She has been fed via a nasogastric tube. She has suffered from diarrhoea for some time and there is erythema around her perineal area.
-If there is no improvement following the implementation of a care plan, at what point would you refer to a specialist such as a tissue viability nurse?

Accepted Answer

If there is no improvement in Freda's condition following the implementation of a care plan, especially given her symptoms of prolonged diarrhea and erythema around her perineal area, a referral to a specialist such as a tissue viability nurse should be made within 3-5 days. This timeframe allows for initial interventions to take effect while ensuring timely specialist input if there's no significant improvement, to prevent further deterioration and manage the risk of skin breakdown or infection effectively.
