Questions About the Integumentary System Questions
Question 1 of 5
Which layer of the skin is made up of dead keratinized cells?
Correct Answer: A
Rationale: The correct answer is A: Epidermis. The epidermis is the outermost layer of the skin, composed mainly of dead keratinized cells called keratinocytes. These cells provide protection and waterproofing to the skin. The dermis (choice B) is the layer beneath the epidermis, containing blood vessels, nerves, and connective tissues. The hypodermis (choice C) is the deepest layer of the skin, containing fat cells and connecting the skin to underlying tissues. Choice D is incorrect as the epidermis is indeed the layer of the skin made up of dead keratinized cells.
Question 2 of 5
The nurse is evaluating a 3-day diet history with a client who has an elevated lipid panel. What meal selection indicates the client is managing this condition well with diet?
Correct Answer: B
Rationale: The correct answer is B because it includes lean protein (baked chicken breast) and vegetables (broccoli, tomatoes). Lean protein helps lower cholesterol levels, while vegetables provide fiber and antioxidants, which are beneficial for heart health. A: Steak and French fries are high in saturated fat and unhealthy fats, which can raise cholesterol levels. C: Fried catfish and cornbread are high in unhealthy fats and carbohydrates, which can worsen lipid panel results. D: Spaghetti with meat sauce and garlic bread are high in refined carbohydrates and unhealthy fats, which can negatively impact cholesterol levels. In summary, choice B is the best option as it includes a balanced meal with heart-healthy components, while the other choices contain items that can potentially worsen the client's lipid panel results.
Question 3 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 4 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 5 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).
