A 30-year-old African American had surgery 6 months ago and the incision site is now raised, indurated, and shiny. This is most likely which type of tissue growth?
A. Melanoma
Melanoma:Melanoma is a type of skin cancer that arises from melanocytes, the cells that produce pigment (melanin) in the skin. Melanoma lesions are typically irregularly shaped, often asymmetrical, with varying shades of color (brown, black, tan, red, blue). They may have an uneven border and can evolve over time. Melanomas can be raised but are not typically described as indurated (firm) and shiny. They are also more commonly associated with changes in color, size, and shape.
B. Keloid
Keloid:A keloid is an abnormal overgrowth of scar tissue that extends beyond the boundaries of the original wound or incision site. Keloids are characterized by their raised appearance, firm or indurated texture, and shiny surface compared to the surrounding skin. They may also be darker than the surrounding skin due to increased collagen deposition. Keloids can develop months after an injury or surgery and are more common in individuals with darker skin tones, such as African Americans.
C. Nevus
Nevus: A nevus, commonly known as a mole or birthmark, is a benign growth of melanocytes or other skin cells. Nevus lesions can vary in appearance but are often flat or slightly raised, with a uniform color (brown, black, tan, or flesh-colored). They are usually not described as indurated or shiny. Nevus lesions can be present at birth (congenital nevus) or develop later in life (acquired nevus).
D. Angioma
Angioma:Angiomas are benign tumors that originate from blood vessels or lymphatic vessels. They can present as red or purplish raised lesions on the skin. Angiomas are typically not described as indurated or shiny. Common types of angiomas include cherry angiomas (small, red papules) and spider angiomas (red, spider-like lesions with central vessels).

Similar Questions
A nurse is caring for a client with a wound. Which of the following pairings reflect the correct wound infection stage with description?
A. Colonization - replicating microorganisms: not yet Infected
Colonization - replicating microorganisms: not yet InfectedThis pairing is correct. Colonization refers to the presence and replication of microorganisms on the wound surface. At this stage, the wound is not yet infected, as there may be microorganisms present, but they have not caused an inflammatory response or tissue damage.
B. Systemic infection - Wound is darker than the surrounding skin with noted drainage present
Systemic infection - Wound is darker than the surrounding skin with noted drainage presentThis description does not match the stage of systemic infection. Systemic infection refers to an infection that has spread beyond the initial wound site, affecting the entire body systemically. The symptoms of systemic infection may include fever, increased heart rate, malaise, and altered mental status. The description provided seems more indicative of a local infection with drainage.
C. Contaminated - infection beyond the wound
Contaminated - infection beyond the wound This pairing is incorrect. Contaminated wounds refer to wounds with a high risk of infection due to the presence of foreign material or significant contamination. However, contamination does not necessarily mean that an infection has already developed beyond the wound. It signifies a risk of infection but does not define the infection stage itself.
D. Local infection - sepsis
Local infection - sepsisThis pairing is incorrect. A local infection is confined to the wound site and may present with symptoms such as erythema, warmth, swelling, pain, and purulent drainage. Sepsis, on the other hand, is a severe systemic response to infection, characterized by widespread inflammation and organ dysfunction. Sepsis is not synonymous with a local infection; it represents a more advanced and life-threatening stage of infection.

Which people have the greatest risk for serious complications secondary to herpes zoster infection? Select all that apply.
A. Healthy middle-aged adult who never had chickenpox
Healthy middle-aged adult who never had chickenpox:This individual has not had chickenpox, which means they are susceptible to varicella-zoster virus (VZV) infection. If they contract herpes zoster (shingles), they are at risk for complications, although typically healthy adults are less likely to experience severe complications compared to immunocompromised individuals or older adults.
B. Older adult who lakes large doses of prednisone for a chronic condition
Older adult who takes large doses of prednisone for a chronic condition:Chronic corticosteroid use, such as prednisone, can suppress the immune system and increase the risk of herpes zoster infection. Additionally, if herpes zoster develops in an older adult, they are at higher risk for complications such as postherpetic neuralgia (persistent nerve pain), bacterial superinfection of the rash, and dissemination of the virus.
C. Middle-aged adult who just started taking chemotherapy
Middle-aged adult who just started taking chemotherapy:Chemotherapy suppresses the immune system, making individuals more susceptible to infections. If a person undergoing chemotherapy develops herpes zoster, they are at increased risk for serious complications due to their weakened immune response.
D. Nurse who recently received the first dose of varicella vaccine
Nurse who recently received the first dose of varicella vaccine:The varicella vaccine is designed to prevent chickenpox and reduce the risk of herpes zoster (shingles) in vaccinated individuals. Therefore, a nurse who received the varicella vaccine is less likely to experience serious complications from herpes zoster infection compared to those who are unvaccinated.
E. Young adult who is positive for the human immunodeficiency virus (HIV):
Individuals with HIV have a weakened immune system, increasing their susceptibility to infections, including herpes zoster. Moreover, herpes zoster in HIV-positive individuals can be more severe, prolonged, and may lead to complications such as disseminated herpes zoster, involving multiple organs and potentially becoming life-threatening.

A nurse assesses a patient’s peripheral IV site and notices edema and tenderness above the site. What action will the nurse take next?
A. Stop the infusion of IV fluids
Stop the infusion of IV fluids:This action may be appropriate if there are signs of infiltration or extravasation, where the IV fluid leaks into the surrounding tissue instead of entering the vein. Stopping the infusion can help prevent further tissue damage and assess the extent of the infiltration.
B. Apply cold compresses to the IV site
Apply cold compresses to the IV site:Cold compresses can help reduce swelling and discomfort at the IV site. This action may be appropriate if there are signs of local inflammation or mild irritation at the insertion site.
C. Elevate the extremity on a pillow
Elevate the extremity on a pillow: Elevating the extremity can help reduce swelling and promote venous return. This action is beneficial if there is edema or localized swelling above the IV site.
D. Flush the catheter with normal saline
Flush the catheter with normal saline:Flushing the catheter with normal saline is not typically the initial action in response to edema and tenderness above the IV site. Flushing is more commonly performed to ensure patency and proper functioning of the IV catheter.
