Questions on the Integumentary System Questions
Question 1 of 5
Treatment of psoriasis includes
Correct Answer: A
Rationale: The correct answer is A: topical therapy. Psoriasis is a chronic skin condition characterized by inflammation and rapid skin cell growth. Topical therapies like corticosteroids, vitamin D analogs, and retinoids are commonly used to reduce inflammation and slow down skin cell growth. This approach targets the affected skin directly, providing relief and improving symptoms. Systemic steroid therapy (choice B) is generally reserved for severe cases due to potential side effects. Surgical debridement (choice C) is not a standard treatment for psoriasis, as it involves removing damaged tissue. Removing the causative factor (choice D) can help in some cases, but psoriasis is a complex condition influenced by genetics, immune system dysfunction, and environmental factors, making it challenging to pinpoint a single cause.
Question 2 of 5
You are teaching a patient about changing his own dressing at home. In addition to teaching the specific dressing routine, you would teach him to evaluate the appearance of the wound and notify his physician if
Correct Answer: B
Rationale: Correct Answer: B - a musty smell comes from the wound Rationale: 1. Musty smell indicates possible infection, which can be serious. 2. Infection can delay healing and lead to complications. 3. Notifying the physician promptly can help in timely treatment. Incorrect Choices: A: the wound looks the same as yesterday - Not a significant change requiring immediate attention. C: a small blister appears in a healed area - Common and may not be urgent. D: the healed area looks very dry and flaky - Likely a minor issue, not indicating infection.
Question 3 of 5
The protein that gives the skin color is:
Correct Answer: B
Rationale: The correct answer is B: melanin. Melanin is the pigment responsible for giving the skin its color. It is produced by melanocytes in the skin's epidermis. Melanin protects the skin from harmful UV radiation and determines the skin's color. Keratin (A) is a structural protein found in the skin, hair, and nails. Collagen (C) is a protein that provides structure and elasticity to the skin. Elastin (D) is a protein that helps the skin to stretch and recoil. However, neither collagen nor elastin are responsible for skin color. The presence of melanin is what primarily determines an individual's skin color.
Question 4 of 5
The sensitivity to touch of an area of skin is determined by the:
Correct Answer: C
Rationale: The correct answer is C: number of receptors. Sensitivity to touch is determined by the presence and distribution of sensory receptors in the skin. These receptors detect touch, pressure, temperature, and pain. The more receptors present in an area, the more sensitive it is to touch. Skin thickness (Choice A), number of pores (Choice B), and number of follicles (Choice D) do not directly impact sensitivity to touch, as they are not involved in the detection of tactile stimuli. Therefore, the correct answer is C as it directly relates to the mechanism of touch sensation.
Question 5 of 5
Which statement is NOT true of the skin and body temperature?
Correct Answer: C
Rationale: The correct answer is C. In a cold environment, vasoconstriction in the dermis does not keep the skin warm. Vasoconstriction reduces blood flow to the skin, which actually decreases heat loss and helps conserve body heat. This is a physiological response to cold temperatures to maintain core body temperature. Choices A, B, and D are incorrect because they accurately describe the functions of the skin and body temperature regulation. Vasodilation in the dermis promotes heat loss in a warm environment, eccrine glands increase sweat secretion as environmental temperature rises to cool the body through evaporation, and pilomotor muscles contract to provide insulation by trapping air close to the skin in cold conditions.
