Questions About the Integumentary System Questions
Question 1 of 5
What is the role of the integumentary system in homeostasis?
Correct Answer: D
Rationale: The correct answer is D because the integumentary system plays multiple roles in maintaining homeostasis. 1. A: It regulates body temperature by sweating or shivering, maintains fluid balance through sweat production, and helps regulate blood pressure through vasodilation or vasoconstriction. 2. B: It acts as a physical barrier to prevent infections and protects against harmful environmental factors. 3. C: The integumentary system is involved in the production of vitamin D when exposed to sunlight. Therefore, all of the choices (A, B, C) are correct, making D the correct answer. Other choices are incorrect as they do not encompass the comprehensive functions of the integumentary system in homeostasis.
Question 2 of 5
A client has been bedridden for several days after major abdominal surgery. What action does the nurse delegate to the UAP for deep vein thrombosis (DVT) prevention?
Correct Answer: A
Rationale: The correct answer is A: Apply compression stockings. This is the appropriate action for DVT prevention in a bedridden client post-surgery as compression stockings help improve blood flow and reduce the risk of blood clots. Ambulation (B) is not suitable for a bedridden client. Encouraging coughing and deep breathing (C) is important for lung health but not directly related to DVT prevention. Offering fluids frequently (D) is important for overall health but does not specifically address DVT prevention.
Question 3 of 5
The cell of stratum germinativum are columnar and very active to form new cells. As new cells are formed the older ones are pushed upwards and at the same time they become-
Correct Answer: A
Rationale: Step-by-step rationale: 1. The stratum germinativum is the deepest layer of the epidermis where new skin cells are formed. 2. New cells are columnar in shape as they are actively dividing and multiplying. 3. As new cells are formed, older cells are pushed upwards towards the surface. 4. As older cells move upwards, they flatten out due to the pressure and tight packing. 5. Therefore, the correct answer is A: Flat, as older cells become flattened as they move towards the surface. Summary: Choice A is correct because older cells in the stratum germinativum become flat as they are pushed upwards. Choices B, C, and D are incorrect as they do not accurately describe the shape transformation of cells in the epidermis.
Question 4 of 5
Complexion of skin in human beings is a mixed effect of -
Correct Answer: C
Rationale: The correct answer is C: Carotene, Melanin, and Haemoglobin. Carotene contributes to the yellowish tone, Melanin is responsible for the color of the skin, and Haemoglobin gives the skin a pinkish hue. Keratin is a protein in the skin and hair, not directly related to complexion. Albinism is a genetic disorder causing lack of melanin production, not a normal component of skin complexion. Carotene, Keratin, and Haemoglobin (option B) do not cover the pigment responsible for skin color (Melanin).
Question 5 of 5
Primary function of sweat glands is
Correct Answer: A
Rationale: The correct answer is A: Thermoregulation. Sweat glands help regulate body temperature by producing sweat, which evaporates and cools the body. Osmoregulation (B) is the regulation of water and solute concentrations in the body, not the primary function of sweat glands. Excretion (C) is the elimination of waste products, which is not the primary function of sweat glands. "None of the above" (D) is incorrect as sweat glands do play a significant role in thermoregulation.
