Correct Answer: A

Rationale: Molluscum contagiosum is a viral skin infection caused by the poxvirus. It typically presents as multiple, flesh-colored, dome-shaped papules with a central umbilication (dimple or depression in the center) on the skin. These lesions are often found on the trunk and extremities and can persist for several months. Molluscum contagiosum is commonly seen in children but can also occur in adults, especially those with weakened immune systems. The lesions are usually asymptomatic but can become inflamed or itchy in some cases. Treatment options include observation, topical therapies, cryotherapy, or curettage.

Correct Answer: D

Rationale: Incompetent cervix, also known as cervical insufficiency, is the most likely cause of the symptoms described. Incompetent cervix is a condition where the cervix begins to dilate and efface prematurely, typically in the second trimester, without contractions or labor. This can lead to painless cervical dilation and bulging of the amniotic sac into the vagina, which can cause vaginal bleeding and crampy abdominal pain. It is a leading cause of second-trimester pregnancy loss. Treatment may involve a cervical cerclage, a surgical procedure where the cervix is stitched closed to provide additional support.

Correct Answer: B

Rationale: The presentation of a pruritic rash with linear streaks and small, fluid-filled blisters following exposure to poison ivy is characteristic of allergic contact dermatitis. Poison ivy contains an oil called urushiol, which is known to cause this type of skin reaction in individuals who are sensitive to it. The linear streaks are often a result of the plant brushing against the skin. Pemphigus vulgaris is an autoimmune condition characterized by the formation of intraepidermal blisters, typically not associated with linear streaks or exposure to irritants like poison ivy. Bullous pemphigoid is characterized by subepidermal blisters, and herpes zoster presents with a painful rash following reactivation of the varicella-zoster virus in a dermatomal pattern, not typically in linear streaks.

Correct Answer: C

Rationale: Dendritic cells play a critical role in initiating adaptive immune responses by capturing antigens from pathogens, migrating to lymphoid organs, and presenting these antigens to naïve T cells. This activation of naïve T cells by dendritic cells is essential for the adaptive immune system to generate specific immune responses against pathogens. Dendritic cells act as professional antigen-presenting cells, which are specialized to capture, process, and present antigens to T cells, thereby facilitating the activation of T cells and the coordination of adaptive immune responses, such as the production of specific antibodies and the generation of memory T cells.

Correct Answer: A

Rationale: Administering systemic analgesia, such as pain medications or anesthesia, before the wound debridement procedure is the most effective way to minimize patient discomfort. These medications will help manage and reduce the pain experienced by the patient during the procedure, making it more tolerable for them. Topical anesthetic cream may provide some localized relief but may not be sufficient for significant pain management during a wound debridement procedure. Using sharp debridement techniques or performing the procedure quickly may help reduce manipulation or duration, respectively, but these actions alone may not adequately address the patient's pain and discomfort. Administering systemic analgesia ensures that the patient's overall pain is managed, promoting a more comfortable and successful wound debridement procedure.
