Question 1 of 5
Rhabdomyosarcoma is the malignant tumor of the
Correct Answer: D
Rationale: Rhabdomyosarcoma is a malignant tumor arising from striated muscle cells, hence the correct answer is D. Striated muscle cells are also known as skeletal muscle cells, which are voluntary muscles responsible for movement. Smooth muscle (Choice A) and visceral muscle (Choice C) are types of involuntary muscles found in internal organs, while cardiac muscle (Choice B) is the muscle specific to the heart. Therefore, choices A, B, and C are incorrect for this question.
Question 2 of 5
The transition zone between the vagina and cervix is a common site of cervical dysplasia and HPV related cancer. What epithelial transition is seen here?
Correct Answer: D
Rationale: The correct answer is D: Vaginal stratified squamous to cervical simple columnar. The transition from stratified squamous epithelium in the vagina to simple columnar epithelium in the cervix is known as the squamocolumnar junction. This transition zone is where cervical dysplasia and HPV-related cancer commonly occur. The stratified squamous epithelium of the vagina provides protection against abrasion, while the simple columnar epithelium of the cervix produces mucus for fertility. Choices A, B, and C are incorrect because they do not accurately describe the epithelial transition seen at this specific location.
Question 3 of 5
Your 20 year old male patient is c/o growths on his penile shaft. He noticed them first about 6 weeks ago, and he thinks there are more now. Denies pain with intercourse or urination. He has had 3 former partners and has been with his current girlfriend for 6 months. She is on the pill so they do not use condoms. Denies fever, weight loss, night sweats. His PMH is unremarkable. He is in college part time and works in construction and is engaged to be married and has no children. On exam, you see several moist papules along all sides of the penile shaft and two on the corona. He has been circumcised. On palpation of his inguinal region there is no inguinal lymphadenopathy. Which abnormality of the penis does this patient most likely have?
Correct Answer: A
Rationale: The correct answer is A: Condylomata acuminata (genital warts) based on the patient's presentation of painless moist papules on the penile shaft and corona, multiple sexual partners, lack of other systemic symptoms, and absence of inguinal lymphadenopathy. This is consistent with HPV infection, the most likely cause of genital warts. Genital herpes (B) typically presents as painful vesicles or ulcers, syphilitic chancre (C) presents as a painless ulcer, and penile carcinoma (D) usually presents as a solitary, indurated, ulcerated lesion with associated lymphadenopathy.
Question 4 of 5
The layer of the uterine wall that is shed during menstruation is the
Correct Answer: A
Rationale: The correct answer is A: endometrium. During menstruation, the endometrium, the inner lining of the uterus, is shed. This layer thickens throughout the menstrual cycle in preparation for possible implantation of a fertilized egg. If fertilization does not occur, the endometrium is shed during menstruation. B: myometrium is incorrect because it is the middle layer of the uterine wall consisting of smooth muscle tissue, responsible for contracting during labor. C: epimetrium is incorrect as it is not a recognized term in anatomy. The outer layer of the uterus is called the perimetrium. D: none of the above is incorrect as the endometrium is the specific layer of the uterine wall that is shed during menstruation.
Question 5 of 5
During the 12-hr period preceding ovulation, which of the following is true?
Correct Answer: B
Rationale: The correct answer is B because a surge of luteinizing hormone (LH) is necessary for ovulation to occur, typically happening 24-36 hours before ovulation. This surge triggers the release of the mature egg from the ovarian follicle. Choices A, C, and D are incorrect as estrogen levels peak just before ovulation, the corpus luteum forms after ovulation, and progesterone levels rise after ovulation, not fall immediately after the LH surge.
