Which is the function of the keratinocytes, a type of skin cell?

To serve as sensory receptors and transmitters for the sense of touch.

To anchor the epidermis to the dermis skin layer.

To provide skin pigmentation as protection from the sun's ultraviolet rays.

To produce a tough, fibrous structural protein for skin protection.

Answer and Explanation

The Correct Answer is D

A. To serve as sensory receptors and transmitters for the sense of touch. Merkel cells, not keratinocytes, function as sensory receptors in the skin, particularly for touch perception.

B. To anchor the epidermis to the dermis skin layer. Hemidesmosomes and basement membrane proteins help anchor the epidermis to the dermis, not keratinocytes.

C. To provide skin pigmentation as protection from the sun's ultraviolet rays. Melanocytes, not keratinocytes, produce melanin, which provides skin pigmentation and protects against UV radiation.

D. To produce a tough, fibrous structural protein for skin protection. Keratinocytes are the primary cells of the epidermis and produce keratin, a strong, fibrous protein that provides structure, durability, and waterproofing to the skin. They also play a role in wound healing and immune defense.

Correct Answer is A

Explanation

A. Staphylococcus aureus abscess around a hair follicle. A furuncle, or boil, is a deep infection of a hair follicle caused by Staphylococcus aureus. It presents as a painful, pus-filled nodule due to bacterial invasion and inflammation. Poor hygiene, friction, or immune suppression can increase susceptibility.
B. Insect or spider bite that becomes infected. While insect bites can introduce bacteria into the skin, they do not directly cause furuncles. Secondary infection may occur, but furuncles specifically arise from infected hair follicles, not bites.
C. Sexual contact with an infected partner. Furuncles are not sexually transmitted infections. While skin-to-skin contact can spread Staphylococcus aureus, furuncles are not a direct result of sexual activity.
D. Inadequate blood supply to the area. Poor circulation can impair wound healing and increase infection risk, but furuncles result from bacterial infection of a hair follicle rather than ischemia.

A. Explain that the child is likely to grow into her weight. B. B .Obtain the child's 3-day diet history based on the mother's input. C. Tell the mother that girls hit their growth spurt before boys so eating more is expected. D. Inquire as to whether or not the school has a physical education program. E. Determine the child's usual physical activity pattern.

Correct Answer is ["B","D","E"]

Explanation

A. Explain that the child is likely to grow into her weight. This is incorrect because a BMI at the 85th percentile indicates that the child is overweight. Without intervention, the risk of continued excess weight gain and future obesity increases.
B. Obtain the child's 3-day diet history based on the mother's input. Assessing the child's dietary habits helps identify potential areas for improvement, such as reducing sugary drinks or increasing fruit and vegetable intake. Understanding the child’s nutrition is essential for developing a healthy eating plan.
C. Tell the mother that girls hit their growth spurt before boys so eating more is expected. While girls do experience growth spurts earlier than boys, this does not justify excessive weight gain. Encouraging healthy eating and physical activity is more appropriate than assuming the child will "grow out of it."
D. Inquire as to whether or not the school has a physical education program. School-based physical activity plays an important role in weight management. If the school lacks a structured program, additional strategies for physical activity should be explored.
E. Determine the child's usual physical activity pattern. Assessing the child’s activity level helps identify if sedentary behaviors (e.g., excessive screen time) are contributing to weight gain. Encouraging regular physical activity is a key part of managing childhood obesity.
