Question

name:
overview: welcome to this weeks application activity! this activity is designed to help you work through the content weve reviewed in chapter 6 and ensure that you understand key concepts. this week, there are two sets of activities:

1. activities for everyone (regardless of major). when you see a section highlighted in green, answer all the questions provided regardless of your major.
2. a major - specific question. when you see a section highlighted in yellow, find and answer the question provided for your category only.

each of these application activities you do is worth 2 points. some of them will be graded based on completion (meaning that if you do the activities and upload it by the deadline, you get full points!). others will be graded for accuracy. however, you will not know ahead of time whether the assignment is being graded for completion or accuracy, so please do your best and take each one seriously!
part 1 (major - specific)
instructions: review each of the categories below to find the one that includes your specific major or health care profession. provide an answer for only that question, ignoring the questions in the other categories.
exercise science, nutrition, pta

• thermoregulation is a key homeostatic function of the integumentary system. describe this negative feedback physiological mechanism.

rad tech and sonography

• as you are positioning an elderly patient for testing you notice a 3 cm size, raised, multicolored dark spot on the posterior surface of their right upper limb. describe what this could be and if it may be life threatening if left unnoticed or treated.

nursing

• patients that are not ambulatory must be turned and repositioned regularly. what can form on the skin as a conscience of failing to turn the patient? describe the layers of the integumentary that may be affected and if this could progress to a life - threatening condition.

surgical tech/respiratory tech/mlt

• a post - surgical patient is febrile (feverish), and the site of the incision is red, hot, swollen, and painful. a sample of the weeping wound must be sent to the lab to determine if the surgical site is infected. the incision was perpendicular to the tension lines. describe what might be happening to the integumentary layers of the surgical site.

answer to question:
pressure ulcers can form on the shin as a consequence of failing to turn the patient. the layers of the integumentary system that may be affected include the epidermis, dermis, and hypodermis. if left untreated, pressure ulcers can progress to a life - threatening condition due to infection and other complications

Explanation:

For the Nursing major - specific question: When non - ambulatory patients aren't turned, pressure ulcers (bedsores) form. The integumentary system has three main layers: the epidermis (outermost, protective), dermis (middle, with blood vessels, nerves, etc.), and hypodermis (innermost, fatty layer for cushioning). If pressure ulcers are left untreated, they can become infected. The infection can spread, leading to conditions like sepsis (a life - threatening whole - body inflammatory response to infection), or osteomyelitis (infection of the bone) if it progresses to deeper tissues, both of which can be fatal.

Answer:

Pressure ulcers can form on the skin as a consequence of failing to turn the patient. The layers of the integumentary system that may be affected include the epidermis, dermis, and hypodermis. If left untreated, pressure ulcers can progress to a life - threatening condition due to infection and other complications.
