The cuticle around a nail is the

Correct Answer: C

Rationale: The correct answer is C: Eponychium. The eponychium is the cuticle surrounding the nail, providing protection and sealing the nail bed. The free edge (Choice A) refers to the tip of the nail, not the cuticle. The lunula (Choice B) is the white, crescent-shaped area at the base of the nail and is not the cuticle. Epicondyle (Choice D) is a bony projection near a joint and is not related to the cuticle. Therefore, the eponychium is the correct answer as it specifically refers to the cuticle around the nail.

Correct Answer: A

Rationale: The correct answer is A: Above 95%. In localized malignant melanoma, early detection and removal significantly increase the survival rate. With timely intervention, the survival rate can exceed 95% due to the cancer being confined to the primary site and not having spread to other parts of the body. This is supported by medical research and statistical data on cancer outcomes. Choices B, C, and D are incorrect because they do not accurately reflect the high survival rate associated with early detection and treatment of localized malignant melanoma. Choice B (75%) is too low, while choices C (60%) and D (40%) are even further from the actual survival rates for early-stage melanoma.

Correct Answer: A

Rationale: The correct answer is A: cell culture. In the management of severe burns, cell culture is not typically used. Fluid replacement is crucial for maintaining circulation and preventing shock. Corticosteroids may help reduce inflammation. Antibiotics are used to prevent or treat infections. Cell culture is not directly involved in the immediate management of severe burns and is more relevant in research or specialized cases.

Correct Answer: A

Rationale: The correct answer is A because perspiration produced by merocrine sweat glands does not directly produce body odor. Body odor is primarily caused by the interaction between sweat and bacteria on the skin. Merocrine sweat glands produce watery sweat that contains electrolytes and waste products. This watery sweat helps regulate body temperature and prevents bacteria from colonizing the skin due to its slightly acidic nature. Therefore, choice A is incorrect as merocrine sweat glands do not directly produce body odor.

Correct Answer: C

Rationale: The correct answer is C: mammary glands. These glands are specifically designed to produce milk in mammals for feeding their young. Sebaceous glands (A) produce oil for the skin, ceruminous glands (B) produce earwax, and eccrine sweat glands (D) produce sweat for thermoregulation. Only mammary glands are responsible for milk production, making choice C the correct answer.
