Disorders in Reproductive System Questions
Question 1 of 5
The purpose of the urethra is to
Correct Answer: D
Rationale: The correct answer is D. The urethra is a tube that carries both urine from the bladder and semen from the reproductive system. This is essential for the excretion of waste (urine) and reproduction (semen). Choice A is incorrect because the urethra carries both urine and semen. Choice B is incorrect as the urethra carries both substances, not just semen. Choice C is incorrect because the urethra carries semen and urine separately, not as a mixture. Overall, choice D is correct because the urethra can carry both semen and urine, just not simultaneously.
Question 2 of 5
Frank is a 24 year old man who presents with multiple vesicles and burning erosions on the shaft of his penis and some tender inguinal adenopathy. Which of the following is most likely?
Correct Answer: B
Rationale: The correct answer is B: Herpes simplex. This is because the presentation of multiple vesicles, burning erosions on the penis shaft, and inguinal adenopathy is classic for genital herpes. Primary syphilis (A) presents with a painless chancre, chancroid (C) with painful ulcers, and gonorrhea (D) with urethral discharge or dysuria. Genital herpes is a viral infection caused by HSV-1 or HSV-2 and typically presents with vesicles, erosions, and adenopathy in the affected area.
Question 3 of 5
The structure between the uterus and the vagina is the
Correct Answer: B
Rationale: The correct answer is B: cervix. The cervix is the structure between the uterus and the vagina, serving as the lower part of the uterus that connects to the vagina. It plays a crucial role in pregnancy by allowing sperm to enter the uterus and facilitating the passage of menstrual blood. Rationale: 1. The uterine tube (A) is not the correct answer as it connects the ovaries to the uterus and is not located between the uterus and the vagina. 2. The vulva (C) is the external genitalia and is not the structure between the uterus and the vagina. 3. The hymen (D) is a thin membrane at the opening of the vagina and does not serve as the structure between the uterus and the vagina.
Question 4 of 5
In the circulatory system of a fetus, which of the following is greater before birth than after birth?
Correct Answer: B
Rationale: The correct answer is B: Right atrial pressure. Before birth, the fetal circulatory system has a shunt called the foramen ovale that allows blood to bypass the lungs, resulting in higher pressure in the right atrium. After birth, when the foramen ovale closes, the right atrial pressure decreases. Incorrect Choices: A: Arterial Po2 - Typically, arterial Po2 is lower in the fetus due to the placenta's oxygenation, but it increases after birth. C: Aortic pressure - Aortic pressure remains relatively stable before and after birth. D: Left ventricular pressure - Left ventricular pressure increases after birth due to the transition from fetal to neonatal circulation.
Question 5 of 5
A 30-year-old woman is breast-feeding her infant. During suckling, which of the following hormonal responses is expected?
Correct Answer: C
Rationale: The correct answer is C: Increased secretion of oxytocin from the paraventricular nuclei. During breast-feeding, oxytocin is released from the paraventricular nuclei in response to suckling. Oxytocin stimulates the contraction of myoepithelial cells around the alveoli and ducts in the breast, facilitating milk ejection. This response helps in the release of milk for the infant's feeding. Rationale: - Choice A is incorrect because ADH is not directly related to breast-feeding. - Choice B is incorrect because ADH is not primarily released from the paraventricular nuclei in response to breast-feeding. - Choice D is incorrect as neurophysin is not directly involved in the hormonal response during breast-feeding.
