A nurse is assessing a patient with possible skin cancer. Select all the clinical presentations that are commonly associated with squamous cell carcinoma.
Presence of atypical moles.
Chronic sun exposure.
Weakened immune system.
History of severe blistering sunburns.
Exposure to certain chemicals.
Correct Answer : B,C,D
Choice A rationale:
Presence of atypical moles.
This statement is not commonly associated with squamous cell carcinoma (SCC).
Atypical moles are more commonly associated with melanoma, not SCC.
Choice B rationale:
Chronic sun exposure.
This statement is accurate.
Chronic sun exposure is a significant risk factor for SCC.
Ultraviolet (UV) radiation from the sun can damage skin cells and increase the risk of SCC development.
Choice C rationale:
Weakened immune system.
This statement is accurate.
A weakened immune system is commonly associated with an increased risk of SCC.
Conditions that compromise the immune system, such as organ transplantation or certain autoimmune diseases, can elevate the risk of SCC.
Choice D rationale:
History of severe blistering sunburns.
This statement is also accurate.
A history of severe blistering sunburns is a risk factor for SCC.
Intense sunburns can damage the skin and increase the likelihood of SCC development.
Choice E rationale:
Exposure to certain chemicals.
This statement is less commonly associated with SCC.
While chemical exposures can contribute to various cancers, including skin cancer, SCC is primarily linked to chronic sun exposure and immune system suppression.

Correct Answer is ["A","C","D"]
Explanation
Choice A rationale:
"We can perform surgical excision to remove the affected area." Surgical excision is a common treatment option for squamous cell carcinoma.
It involves removing the cancerous tissue along with a margin of healthy tissue to ensure complete removal.
Choice B rationale:
"We'll use chemotherapy to target the cancer cells." Chemotherapy is typically not the first-line treatment for squamous cell carcinoma.
It may be considered in advanced cases or when other treatments are not effective.
However, it is not the primary treatment option for this type of skin cancer.
Choice C rationale:
"Radiation therapy can help shrink the tumor." Radiation therapy is a viable treatment option for squamous cell carcinoma, especially when surgery is not feasible due to the location of the tumor or other factors.
It can help shrink the tumor and target cancer cells.
Choice D rationale:
"We recommend Mohs surgery for your condition." Mohs surgery is often recommended for the treatment of squamous cell carcinoma, particularly when the cancer is in sensitive areas or when preserving healthy tissue is critical.
Mohs surgery involves the removal of the cancerous tissue in layers, with immediate examination to ensure complete removal.
Correct Answer is C
Explanation
Choice A rationale:
"Use sunscreen with an SPF of 10 or higher for daily protection" is not the best recommendation.
While an SPF of 10 provides some level of protection, it may not offer adequate protection for extended sun exposure or intense sunlight.
Higher SPF values provide better protection against UV radiation, which is important for preventing skin damage and skin cancer.
Choice B rationale:
"Select a sunscreen with the highest SPF available for maximum protection" is not necessarily the best advice either.
While higher SPF values offer more protection, they may not provide significantly greater protection than SPF 30 or 50.
Additionally, very high SPF values can be associated with increased cost and may not be necessary for everyday use.
Choice C rationale:
"SPF 30 or higher is recommended for adequate sun protection" is the most appropriate recommendation.
SPF 30 is considered to be a good balance between protection and usability.
It provides adequate protection against UVB radiation, which is responsible for sunburn and a significant portion of skin cancer risk.
SPF 30 filters out about 97% of UVB rays, whereas SPF 50 filters out about 98%, making SPF 30 a practical choice for daily use.
Choice D rationale:
"SPF is not essential; wearing a hat is sufficient" is not an accurate recommendation.
While wearing a wide-brimmed hat can provide some protection against the sun's harmful rays, it is not a substitute for sunscreen.
Sunscreen offers broad-spectrum protection and should be used in conjunction with other sun protection measures for comprehensive sun safety.
