Anatomy - Exam 2 Practice Questions - Integument
Critical burn injuries will likely be treated with all of the following EXCEPT __________.
pressing an ice-cold washcloth, towel, or pad to the burned area. Pressing a cold pad to a mildly burned site, such as a sunburn, may relieve some discomfort. For a critical burn, however, this is not as important as treating other factors.
Surface skin cells regenerate from stem cells found in which specific region?
In the stratum basale. The stratum basale is the deepest layer of the epidermis and the location of highly mitotic cells.
Why does your skin remain red after a bad sunburn?
Inflammation causes increased blood flow.
The integument's ability to resist tearing when stretched is largely due to the _____.
Network of collagen fibers present in the reticular layer of the dermis. The dermis is thick and strong, made up of dense fibrous connective tissue.
Which of the following layers is found only on the palms of the hands or the soles of the feet?
Stratum lucidum. Stratum lucidum is found only in the thick skin on the soles of the feet or palms of the hands. When present, it is located between the stratum corneum and stratum granulosum,.
Which epidermal cells act as sensory touch receptors?
Tactile cells (merkle cells) Tacile means "touch". Tactile cells along the border between the epidermis and dermis are touch receptors.
How can the rule of nines help indicate whether a burn should be considered critical?
The rule of nines can provide a rough estimation of the percentage of body surface affected by a burn. The rule of nines divides the body into 11 regions of 9%each, plus 1% for the perineal area. For example, one whole arm, front and back, accounts for approximately 9% of the body surface. Critical burns are classified by the degree or depth of the burn and the surface area affected.
Which of the following best describes a third-degree burn?
a burn that affects the entire thickness of the integument. Degree refers to the regions of skin affected by the burn. Third-degree burns are full-thickness burns that involve the entire thickness of the skin.
Why would a third-degree burn be less painful than a first- or second-degree burn involving the same body area?
destruction of underlying pain receptors
Serious burns pose a significant threat to the body because they can __________.
lead to kidney failure and circulatory shock Burns can destroy the layers of skin that retain fluids in the body. When burns cause a drastic loss of these fluids, including electrolytes and proteins, kidney and circulatory failure can occur.
