Question 1 of 5
Elbow, knee are _____ type of joints
Correct Answer: C
Rationale: The correct answer is C: Hinge. Elbow and knee joints are classified as hinge joints because they primarily allow movement in one plane, similar to a door hinge. These joints enable flexion and extension movements, which are characteristic of hinge joints. The other choices (A: Ball-and-socket, B: Socket, D: Pivot) do not accurately describe the structure and function of the elbow and knee joints. Ball-and-socket joints allow for a wider range of motion in multiple directions, sockets are components of ball-and-socket joints, and pivot joints allow rotational movement around a central axis, none of which align with the movement pattern of the elbow and knee joints. Therefore, the correct classification for elbow and knee joints is hinge joints due to their specific range of motion.
Question 2 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 3 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 4 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.
Question 5 of 5
Delayed breathing at birth is a common danger faced by newborn infants. What is a frequent cause of delayed breathing?
Correct Answer: A
Rationale: The correct answer is A: Fetal hypoxia during the birth process. Fetal hypoxia, which is a lack of oxygen to the fetus during birth, can lead to delayed breathing in newborn infants. This lack of oxygen can result from various factors such as umbilical cord compression or placental insufficiency. Maternal hypoxia (choice B) and hypercapnia (choices C and D) may affect the fetus indirectly but are not direct causes of delayed breathing in newborns. Therefore, the correct choice is A, as it directly addresses the specific cause of delayed breathing in newborn infants.
