Which of the following actions is recommended for controlling severe external bleeding from an extremity?

Correct Answer: C

Rationale: When controlling severe external bleeding from an extremity, the recommended action is to apply direct pressure with a sterile dressing. Direct pressure helps to stop the bleeding by promoting clot formation and reducing blood flow from the wound. This method is effective in most cases and should be the first response to control bleeding. Elevating the extremity above the level of the heart can be helpful in some cases, but direct pressure is the initial recommended action. Applying a tourniquet proximal to the injury site should only be done as a last resort when other methods are not successful, as it can lead to complications such as tissue damage. Removing any impaled objects can actually worsen the bleeding and should be avoided unless necessary for immediate life-saving measures.

Correct Answer: C

Rationale: The appropriate initial management for a conscious patient experiencing a syncopal episode (fainting) is to provide reassurance and assist the patient to a lying position. This is important to ensure adequate blood flow to the brain and to prevent further injury in case the patient faints again. Elevating the legs above the level of the heart is not recommended as a routine intervention for syncope. Administering intravenous fluids rapidly is not usually needed in the initial management of syncope without signs of dehydration or significant bleeding. Administering oxygen via nasal cannula is not necessary for most cases of syncope unless there are specific indications such as signs of respiratory distress.

Correct Answer: A

Rationale: The clinical presentation of heavy menstrual bleeding, iron deficiency anemia, an enlarged uterus, and irregularly shaped masses palpated on pelvic examination is most indicative of leiomyomas, also known as uterine fibroids. Leiomyomas are benign smooth muscle tumors that commonly occur in women of reproductive age. They can lead to heavy menstrual bleeding and iron deficiency anemia due to their size and location within the uterus. On pelvic examination, leiomyomas can be felt as irregularly shaped masses within the uterine wall. This presentation is classic for leiomyomas and distinguishes them from conditions such as endometrial polyps, endometrial hyperplasia, and adenomyosis.

Correct Answer: B

Rationale: The recommended screening test for cervical cancer prevention in women aged 21 to 65 years is cytology, also known as a Pap smear. The Pap smear is a test that looks for changes in the cells of the cervix that could indicate the presence of cervical cancer or pre-cancerous conditions. This test is recommended every 3 years for women aged 21-29 years, and every 3-5 years for women aged 30-65 years, depending on the screening method used. HPV testing alone or co-testing with both cytology and HPV testing may be used in certain situations, but for most women in this age group, cytology (Pap smear) alone is the recommended screening test.

Correct Answer: C

Rationale: Among the given options, teratoma (dermoid cyst) is the most common type of ovarian tumor in women of reproductive age. Dermoid cysts are a type of ovarian teratoma that contains tissues derived from the ectoderm (skin), mesoderm (bone, muscle), and endoderm (mucous membranes). They are usually benign and can contain a variety of elements such as hair, teeth, bone, and sebaceous material. Serous cystadenomas and mucinous cystadenomas are more commonly seen in older women, whereas endometriomas are typically associated with endometriosis rather than being the most common ovarian tumor type in women of reproductive age.
