Question

Which of the following is the most lethal form of skin cancer?

Answer 1

Correct Answers:

Malignant melanoma

Rationale :

🧬Malignant melanoma develops from melanocytes and can spread rapidly to distant organs.

⚠️Its high potential for early metastasis makes it the most lethal major form of skin cancer.

🔍Early detection of changes in asymmetry, borders, color, diameter, and evolution improves survival.

☀️Limiting ultraviolet exposure and monitoring suspicious lesions are important preventive measures.

📌Core Message:

Malignant melanoma is the most lethal skin cancer because of its strong potential for early metastasis.

Answer 2

Correct Answers:

Body surface area affected by the burn

Rationale :

🔥The Rule of Nines estimates the percentage of total body surface area affected by burns.

📊Major body regions are assigned percentages based on multiples of nine.

💧The estimated burn surface area helps guide fluid-resuscitation calculations and treatment decisions.

🩺The method is primarily used for significant partial-thickness and full-thickness burns.

📌Core Message:

The Rule of Nines estimates the percentage of total body surface area affected by a burn.

Answer 3

Correct Answers:

Full-thickness

Rationale :

🔥A full-thickness burn destroys the entire epidermis and dermis.

🧱The injury may extend into subcutaneous tissue and deeper structures.

⚠️Because nerve endings are destroyed, the central area may have little or no pain.

🔪Healing usually requires skin grafting because normal skin structures are extensively damaged.

📌Core Message:

A full-thickness burn extends through the epidermis and the entire dermis.

Answer 4

Correct Answers:

Waxy-white, or charred appearance with little or no pain

Rationale :

⚪A waxy-white, brown, or charred appearance is characteristic of full-thickness tissue destruction.

⚠️The burned area may be painless because the injury destroys sensory nerve endings.

🧱The skin often appears dry, firm, and leathery because of eschar formation.

🔪These burns usually require surgical debridement and skin grafting.

📌Core Message:

A full-thickness burn commonly appears waxy-white or charred and may be painless because nerves are destroyed.

Answer 5

Correct Answers:

Fluid resuscitation

Rationale :

💧Severe burns cause massive movement of fluid from the bloodstream into the interstitial tissues.

🩸This fluid shift can produce hypovolemic shock and inadequate organ perfusion.

🚑Rapid intravenous fluid resuscitation helps restore circulating volume and protect kidney and cardiovascular function.

🩺Nutrition, grafting, and wound care are important after the client’s circulation is stabilized.

📌Core Message:

Severe burns require immediate fluid resuscitation to prevent hypovolemic shock and organ failure.

Answer 6

Correct Answers:

Genetic predisposition
Environmental factors (carcinogen exposure)

Rationale :

🧬A genetic predisposition can increase susceptibility to mutations that disrupt normal cell growth.

☢️Environmental exposure to carcinogens, including tobacco smoke, radiation, and chemicals, can damage cellular DNA.

⚠️Cancer often develops through an interaction between inherited vulnerability and environmental exposure.

🔬Accumulated genetic mutations may eventually allow cells to grow and divide without normal control.

📌Core Message:

Cancer commonly develops through a combination of genetic predisposition and environmental carcinogen exposure.

Answer 7

Correct Answers:

Mutation of poorly differentiated cells

Rationale :

🧬Malignant tumors consist of poorly differentiated cells that have lost many normal structural and functional characteristics.

⚠️These abnormal cells divide rapidly and ignore normal growth-control signals.

🔬Poor differentiation is associated with greater aggressiveness and metastatic potential.

📈As mutations accumulate, the cells become increasingly anaplastic and invasive.

📌Core Message:

Malignant tumors are composed of poorly differentiated, rapidly dividing cells with abnormal growth control.

Answer 8

Correct Answers:

Do not function as normal cells

Rationale :

🧬Cancer cells lose normal differentiation and specialized function as mutations accumulate.

📈They often divide uncontrollably and ignore normal cell-cycle regulation.

🔗Many malignant cells lose normal cell adhesion, allowing invasion and metastasis.

♻️They may resist normal programmed cell death, enabling prolonged survival.

📌Core Message:

Cancer cells lose normal function, growth control, adhesion, and programmed cell death.

Answer 9

Correct Answers:

Cancer cells use up much of the available resources

Rationale :

🧬Cancer cells have high metabolic demands and consume large amounts of nutrients and energy.

⚖️Competition for resources contributes to weight loss, fatigue, and muscle wasting.

🔥Tumor-related inflammatory substances can also accelerate protein and fat breakdown.

🩺This systemic wasting condition is commonly described as cancer cachexia.

📌Core Message:

Cancer-related fatigue and muscle wasting occur because tumors consume resources and promote cachexia.

Answer 10

Correct Answers:

Usually have a capsule around them
May function similarly to normal cells

Rationale :

🧱Benign tumors are often surrounded by a fibrous capsule, which limits local spread.

🔬Their cells are usually well differentiated and resemble the normal tissue of origin.

⚙️Because of this differentiation, some benign tumors may retain normal cellular functions.

🐢They generally grow slowly and do not invade or metastasize like malignant tumors.

📌Core Message:

Benign tumors are usually encapsulated, well differentiated, and noninvasive.
