Correct Answer: A

Rationale: Neutrophils are a type of white blood cell that play a crucial role in immune defense against pathogens, particularly in phagocytosis - the process by which they engulf and destroy invading microorganisms. In a severe fungal infection, impaired neutrophil function would most likely affect their ability to effectively perform phagocytosis, leading to a compromised immune response against the fungal pathogen. This would result in increased susceptibility to the infection and potentially severe outcomes for the patient. Antibody production, cytokine secretion, and mast cell degranulation are important components of the immune response, but neutrophils are primarily responsible for phagocytosis in the innate immune system.

Correct Answer: A

Rationale: The scenario described, including cyclic pelvic pain, dysmenorrhea, dyspareunia, retroverted uterus, and a nodular mass behind the uterus, is most indicative of endometriosis. Endometriosis is a gynecological condition in which tissue similar to the endometrium (the tissue that lines the uterus) is found outside the uterus, typically on structures within the pelvis. The presence of endometrial tissue in abnormal locations can lead to symptoms such as pelvic pain, especially during menstruation (dysmenorrhea), painful intercourse (dyspareunia), and the formation of nodular masses (endometriomas) that can be felt on pelvic examination. It is important to note that while adenomyosis and uterine fibroids (leiomyomas) can also cause pelvic pain and dysmenorrhea, the specific findings of retroverted uterus and palpable nodular mass behind

Rationale: Sonography, also known as ultrasound, is a non-invasive imaging technique that uses high-frequency sound waves to create images of structures inside the body. In the context of a patient who is pregnant, sonography is commonly used to assess the well-being of the fetus. It allows healthcare providers to monitor the growth and development of the fetus, evaluate the placenta, amniotic fluid levels, and detect any abnormalities that may be present.
