Human Reproductive System Quizlet Questions
Question 1 of 5
The menstrual cycle is triggered each month by
Correct Answer: C
Rationale: The correct answer is C: hormones. Hormones, specifically estrogen and progesterone, control the menstrual cycle by regulating the release of an egg from the ovary, thickening the uterine lining, and preparing the body for pregnancy or menstruation. Hormonal fluctuations throughout the cycle signal the body to shed the uterine lining if fertilization does not occur. Choices A and B are incorrect as they describe events during the menstrual cycle rather than the trigger itself. Choice D, sexual intercourse, does not directly trigger the menstrual cycle but may lead to conception, which is one of the outcomes of the menstrual cycle.
Question 2 of 5
Your 22 year old female patient is c/o severe burning with urination, fever of 101, and aching all over. She takes oral contraceptives. She reports one new partner within the last month. Palpation of the inguinal nodes reveals bilateral lymphadenopathy. There are more than 10 shallow ulcers along each side of the vulva. She is very tender at the introitus. Urine has some WBCs but no RBCs or bacteria. Which disorder of the vulva is most likely?
Correct Answer: A
Rationale: The correct answer is A: Genital herpes. The patient's symptoms of severe burning with urination, fever, aching, new sexual partner, bilateral lymphadenopathy, multiple shallow ulcers along the vulva, tenderness at the introitus, and absence of RBCs or bacteria in urine are all consistent with genital herpes. Genital herpes is caused by the herpes simplex virus (HSV) and presents with painful vesicular lesions in the genital area. The presence of ulcers and lymphadenopathy points towards an infectious etiology. Condylomata acuminata (choice B) presents as genital warts caused by HPV, which typically do not cause ulcers. Syphilitic chancre (choice C) presents as a painless ulcer with a firm base, not multiple ulcers. Epidermoid cyst (choice D) presents as a benign skin lesion, not with the symptoms described.
Question 3 of 5
The hormone that stimulates uterine contractions is
Correct Answer: A
Rationale: The correct answer is A: oxytocin. Oxytocin is the hormone responsible for stimulating uterine contractions during labor and childbirth. It is produced by the pituitary gland and plays a crucial role in the initiation and progression of labor. Estrogen (B) and progesterone (D) are involved in the menstrual cycle and pregnancy maintenance but do not directly stimulate uterine contractions. Granular cell carcinoma (C) is a type of cancer and not a hormone related to uterine contractions.
Question 4 of 5
In the following figure, which lines most likely reflect the responses in a patient with nephrogenic diabetes insipidus?
Correct Answer: B
Rationale: The correct answer is B because in nephrogenic diabetes insipidus, the kidney tubules are unable to respond to antidiuretic hormone (ADH). This results in the inability to concentrate urine, leading to excessive dilute urine output. Lines A and D in the figure represent a high urine output (polyuria) and low urine osmolality, which are characteristic of nephrogenic diabetes insipidus. Choice A (A and C) is incorrect because line C does not show low urine osmolality. Choice C (B and C) is incorrect because line B does not show high urine output. Choice D (B and D) is incorrect because line D does not show low urine osmolality.
Question 5 of 5
Why is it important to feed newborn infants every few hours?
Correct Answer: A
Rationale: Step 1: Newborn infants have limited hepatic capacity to store and synthesize glycogen and glucose. Step 2: This limited capacity results in the plasma glucose concentration not being maintained in a normal range for more than a few hours after feeding. Step 3: Feeding every few hours ensures a constant supply of glucose to maintain plasma glucose levels. Step 4: Thus, it is important to feed newborn infants every few hours to prevent hypoglycemia. Summary: A: Correct - Maintaining plasma glucose levels due to limited hepatic capacity. B: Incorrect - Protein concentration is not the primary concern for feeding frequency. C: Incorrect - Keeping food in the stomach constantly does not improve gastrointestinal function. D: Incorrect - Hypoproteinemic edema is not the primary reason for feeding frequency.
