K.B., a 32-year-old fitness instructor, had noticed a "tiny hard lump" at the base of her left nostril while cleansing her face. The lesion had been present for about two months when she consulted a dermatologist. She had recently moved north from Florida, where she had worked as a lifeguard. She thought the lump might have been triggered by the regular tanning salon sessions she had used to retain her tan because it did not resemble the acne pustules, blackheads, or resulting scars of her adolescent years. Although dermabrasion had removed the obvious acne scars and left several areas of dense skin, this lump was brown-pigmented and different. K.B. was afraid it might be a malignant melanoma. On examination, the dermatologist noted a small pearly-white nodule at the lower portion of the left ala (outer flared portion of the nostril). There were no other lesions on her face or neck.

A plastic surgeon excised the lesion and was able to reapproximate the wound edges without a full-thickness skin graft. The pathology report identified the lesion as a basal cell carcinoma with clean margins of normal skin and subcutaneous tissue and stated that the entire lesion had been excised. K.B. was advised to wear SPF 30 sun protection on her face at all times and to avoid excessive sun exposure and tanning salons.

K.B.âs basal cell carcinoma may have been caused by chronic exposure to the sun and use of an ultraviolet tanning bed. The scientific explanation for this is the:_______

a. autoimmune response
b. actinic effect
c. allergic reaction
d. sunblock tanning lotion theory

Answers

Answer: actinic effect

Explanation:

Since we are informed that K.B.âs basal cell carcinoma may have been caused by the chronic exposure to the sun and use of an ultraviolet tanning bed.

We should note that the reason for this can be due to actinic effect. Actinic effect occurs when a radiant energy results into a chemical effect. The sun is known to be a producer of radiant energy.

Hazel is a toddler she loves watching other children play however she really joins them in the play what do we call this form a play

Answers

Answer:

Onlooker play

Explanation:

I think you meant, "she rarely joins them in the play."

When it comes to "playing," kids follow 6 stages until they're able to interact with other kids. These are the stages:

1. Unoccupied play

2. Solitary play

3. Onlooker play

4. Parallel play

5. Associative play

6. Cooperative play

Hazel is showcasing the "Onlooker play," which means she is just an "onlooker" or a "spectator." She tries to observe kids interacting with each other; however, she doesn't join them because she "feels safe" watching them from a distance.

Answer:

pretty sure its solitary play for plato
