What is the primary purpose of splinting a fractured extremity in the pre-hospital setting?

Correct Answer: A

Rationale: The primary purpose of splinting a fractured extremity in the pre-hospital setting is to immobilize the injured area in order to prevent further injury. By stabilizing the fracture, splinting helps to reduce movement, which can alleviate pain, prevent additional damage to surrounding tissues, and minimize the risk of causing more harm during transport or while providing care. Splinting also helps to maintain proper alignment of the bones, which is crucial for the healing process and long-term function of the injured limb.

Correct Answer: A

Rationale: Polycystic ovary syndrome (PCOS) is a common hormonal disorder in women of reproductive age. The classic symptoms of PCOS include irregular menstrual cycles, hirsutism (excess hair growth in a male pattern), and acne. Women with PCOS often have enlarged ovaries with multiple small cysts. Other common features include obesity, insulin resistance, and infertility. Endometriosis is characterized by the presence and growth of endometrial-like tissue outside the uterus, leading to symptoms such as pelvic pain and infertility. Ovarian cancer usually presents with nonspecific symptoms and is less likely in a young woman with these specific symptoms. Uterine fibroids are benign tumors that can cause heavy menstrual bleeding and pelvic pressure but are less likely to be associated with hirsutism and acne.

Correct Answer: A

Rationale: Endometriosis is a condition characterized by the abnormal growth of endometrial tissue outside the uterus. One common symptom of endometriosis is excessive menstrual bleeding, known as menorrhagia. This excessive bleeding is due to the presence of endometrial tissue in abnormal locations, leading to inflammation, scarring, and blood accumulation. In severe cases, endometriosis can lead to the formation of adhesions, cysts, and scar tissue, causing significant pain and fertility issues for affected individuals. Endometrial hyperplasia, leiomyomas (uterine fibroids), and adenomyosis are other gynecological conditions, but they do not involve the abnormal proliferation of endometrial tissue outside the uterus like endometriosis does.

Correct Answer: B

Rationale: Adenomyosis is a condition characterized by the presence of endometrial tissue within the myometrium (muscle wall) of the uterus. It can present with symptoms such as cyclic pelvic pain, dysmenorrhea (painful periods), and infertility. On pelvic examination, the uterus may be retroverted (tilted backward) and enlarged due to the presence of adenomyotic nodules within the uterine muscle. Adenomyosis can also cause heavy menstrual bleeding (menorrhagia). Endometriosis, on the other hand, involves the presence of endometrial tissue outside the uterus and can cause similar symptoms but is less likely to result in uterine enlargement or retroversion. Leiomyomas (uterine fibroids) are benign tumors of the uterine muscle and can also cause pelvic pain and abnormal uterine enlargement but are less likely to be associated with dysmenorrhea and infertility

Correct Answer: B

Rationale: During the acute phase response, C-reactive protein (CRP) primarily serves to activate the complement system. CRP binds to phosphocholine on the surface of pathogens, allowing for the activation of the classical pathway of the complement system. This leads to the recruitment of immune cells, opsonization of pathogens, and enhancement of phagocytosis. The activation of the complement system by CRP plays a crucial role in the host defense against infections, aiding in the elimination of pathogens and the resolution of inflammation.
