Integumentary System CPT Questions and Answers Questions
Question 1 of 5
Study of skin is known as-
Correct Answer: B
Rationale: The correct answer is B: Dermatology. Dermatology is the branch of medicine that deals with the study of skin and its diseases. "Hypology" (Choice A) is not a recognized term related to skin study. "Tricology" (Choice C) is the study of hair and scalp, not skin. "Mastology" (Choice D) is the study of breast diseases, not skin. Therefore, the correct term for the study of skin is Dermatology.
Question 2 of 5
The layer of the skin that contains the blood vessels and nerves that are closest to the surface of the skin is the ______ layer.
Correct Answer: B
Rationale: The correct answer is B: Papillary. This layer is located right below the epidermis, contains blood vessels, nerves, and capillaries closest to the skin surface, aiding in temperature regulation and sensation. The subcutaneous layer (A) is deeper and primarily consists of fat cells. The reticular layer (C) is deeper than the papillary layer and mainly provides structural support. Hypodermal (D) is not a recognized skin layer term. Thus, the papillary layer is the correct choice due to its proximity to the skin surface and functions related to blood vessels and nerves.
Question 3 of 5
Water loss due to evaporation of a fluid that has penetrated through the skin is termed:
Correct Answer: B
Rationale: The correct answer is B: Latent. Evaporation of a fluid through the skin is considered latent water loss because it occurs without any noticeable signs or symptoms. This type of water loss is not easily perceptible and may not be readily apparent to an individual. Sensible water loss (choice A) refers to water loss that is easily measurable, such as through sweating. Intensible (choice C) and discrete (choice D) are not terms used to describe water loss through evaporation of fluids. Therefore, the correct term for water loss due to evaporation through the skin is latent.
Question 4 of 5
If the epidermis, dermis, and part of hypodermis are burned, it is classified as
Correct Answer: A
Rationale: The correct answer is A: full thickness. When the epidermis, dermis, and part of the hypodermis are burned, it involves damage to all layers of the skin, including the deepest layer. This results in complete destruction of the skin layers, making it a full-thickness burn. The other choices are incorrect because: B: Second degree burns involve damage to the epidermis and part of the dermis, not the hypodermis. C: Partial thickness burns affect only parts of the epidermis and dermis, not the hypodermis. D: First degree burns are superficial, involving only the epidermis and not the dermis or hypodermis.
Question 5 of 5
Dandruff is a disorder that results in dry skin flakes forming in the scalp. A common cause of dandruff could be
Correct Answer: A
Rationale: Step-by-step rationale: 1. Dandruff is caused by excessive shedding of dead skin cells on the scalp. 2. Inflammation around sebaceous glands can lead to increased production of sebum, which can contribute to dandruff. 3. Sebaceous glands produce oil that can mix with dead skin cells and lead to flaking. 4. Inactive apocrine sweat glands, inactive merocrine sweat glands, and overactive arrector pili muscles are not directly related to the production of skin flakes on the scalp. Summary: - Choice A is correct as inflammation around sebaceous glands can lead to increased sebum production, contributing to dandruff. - Choices B, C, and D are incorrect as they are not directly associated with the production of dry skin flakes on the scalp.
