What is the survival rate of a localized malignant melanoma that is detected and removed in the early stages of the cancer?

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 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.

Correct Answer: D

Rationale: The correct answer is D: sweat glands. Sweat glands help regulate body temperature and water content by secreting sweat, which evaporates and cools the body. Sebaceous glands (A) secrete oil for lubrication, Dysplastic Nevi (B) are atypical moles, and a puncture wound (C) is unrelated to regulating body temperature and water content.

Correct Answer: C

Rationale: The correct answer is C because checking for swelling, bleeding, or pain associated with the surgery falls within the scope of practice for an experienced nursing LPN/LVN. LPNs/LVNs are trained to assess and monitor patients for signs of complications post-surgery. A, B, and D involve client education and teaching, which typically fall under the scope of practice for registered nurses. LPNs/LVNs may assist with reinforcing education provided by the RN but are not typically responsible for initial teaching or education related to a new diagnosis or surgical procedure.
