Which of the following actions is indicated in the management of a patient with an open chest wound (sucking chest wound)?

Correct Answer: A

Rationale: An open chest wound, also known as a sucking chest wound, can lead to a collapsed lung and respiratory distress. Immediate management involves sealing the wound to prevent air from entering the pleural space and further compromising the patient's respiratory function. Applying a sterile dressing over the wound helps to prevent contamination and occluding the wound with an airtight covering, such as an occlusive dressing, can effectively reduce the risk of a tension pneumothorax, a serious complication that can arise from a sucking chest wound. These interventions help to stabilize the patient's condition and improve the chances of a successful recovery. Administering supplemental oxygen, though beneficial, would be secondary to the primary management of sealing the chest wound. Providing emotional support is important but addressing the physical emergency takes precedence. Elevating the patient's legs would not be appropriate in managing an open chest wound.

Correct Answer: C

Rationale: Colposcopy with biopsy is the most appropriate diagnostic test for evaluating a woman with suspected cervical dysplasia. Colposcopy is a procedure in which a special magnifying instrument called a colposcope is used to examine the cervix for any abnormal areas. If abnormal tissue is identified during colposcopy, a biopsy will be taken to confirm the presence of cervical dysplasia and determine the severity. This allows for a more accurate diagnosis and appropriate management of the condition. Pap smear, although a screening test for cervical dysplasia, may not provide a definitive diagnosis and may require further evaluation with colposcopy and biopsy. Endometrial biopsy and transvaginal ultrasound are not indicated for evaluating cervical dysplasia specifically.

Correct Answer: B

Rationale: The scenario described in the question is most indicative of endometriosis. Endometriosis is a gynecological condition in which tissue similar to the lining of the uterus grows outside of the uterus. Classic symptoms of endometriosis include cyclic pelvic pain, dysmenorrhea (painful periods), and infertility. The presence of a "chocolate cyst" (also known as an endometrioma) within the ovary on pelvic ultrasound is a characteristic finding in endometriosis. These cysts are filled with old blood, giving them a dark, chocolate-like appearance on imaging. Polycystic ovary syndrome (PCOS) typically presents with irregular periods, signs of hyperandrogenism, and multiple small follicles on ultrasound. Ovarian torsion and ovarian cyst rupture would present with acute-onset symptoms and may not necessarily be associated with cyclic pelvic pain and dysmenorrhea as described in the

Correct Answer: B

Rationale: The symptoms of cyclic pelvic pain, dysmenorrhea (painful menstruation), dyspareunia (painful intercourse), and tender nodules along the uterosacral ligaments are classic findings associated with endometriosis. In endometriosis, tissue similar to the lining of the uterus (endometrium) grows outside the uterus, commonly on the ovaries, fallopian tubes, and pelvic peritoneum. The presence of tender nodules along the uterosacral ligaments is known as "nodularity" and is a characteristic feature of advanced endometriosis. It occurs due to the formation of endometrial implants that respond to hormonal changes during the menstrual cycle, resulting in inflammation, scarring, and pain in affected areas.

Correct Answer: C

Rationale: Mast cells are primarily responsible for mediating allergic responses such as severe allergies. When an allergen triggers the immune response, mast cells release histamine, leukotrienes, and other inflammatory mediators. These substances cause symptoms such as difficulty breathing, hives, and swelling. Basophils also release histamine, but mast cells are more abundant in tissues and play a significant role in allergic reactions. Eosinophils are involved in allergic reactions but are more focused on combating parasitic infections. Neutrophils are not typically involved in allergic responses but play a key role in combating bacterial infections.
