Anatomy and Physiology of the Female Breast Questions
Question 1 of 5
The myometrium of the uterus responds to which hormone?
Correct Answer: A
Rationale: The correct answer is A: Prostaglandins and oxytocin. Prostaglandins and oxytocin are the primary hormones that stimulate contractions in the myometrium of the uterus during labor. Progesterone and estrogen (choice B) are involved in the menstrual cycle and maintaining pregnancy, not in uterine contractions. Oxytocin, relaxin, and prostaglandin E (choice C) have roles in labor but are not the primary hormones that directly act on the myometrium. Progesterone and testosterone (choice D) do not directly influence uterine contractions.
Question 2 of 5
Testosterone is responsible for the development of which of the following? Select all that apply.
Correct Answer:
Rationale: Correct Answer: A, B, and C Rationale: A: Testosterone is crucial for the development of male reproductive organs such as the testes and prostate gland. B: Testosterone plays a key role in the development of male secondary sex characteristics like facial hair and deepening of voice. C: Testosterone contributes to the growth and maintenance of male muscle mass, influencing strength and physical performance. Summary of Incorrect Choices: D: Testosterone does not directly affect male height. Height is primarily determined by genetics and growth hormone levels.
Question 3 of 5
A woman who is charting her basal temperature during her cycle notes a sudden increase of 0.6°F in her waking temperature on the 15th day of her menstrual cycle. Which hormone is the cause of this finding?
Correct Answer: B
Rationale: The correct answer is B: Progesterone. On the 15th day of the menstrual cycle, the woman would have ovulated, leading to the release of the egg and the formation of the corpus luteum. The corpus luteum produces progesterone, which causes an increase in basal body temperature. FSH (A) is responsible for stimulating the growth of ovarian follicles, not the temperature increase. Estrogen (C) levels peak before ovulation but do not cause the post-ovulation temperature rise. Prostaglandin (D) is involved in various physiological processes but not directly related to the basal temperature increase post-ovulation.
Question 4 of 5
What condition would the nurse suspect in a patient who presents with very painful menstrual cramps that prevent them from working each month?
Correct Answer: B
Rationale: The correct answer is B: dysmenorrhea. Dysmenorrhea refers to painful menstrual cramps that can be severe enough to interfere with daily activities like work. This condition is common and can be caused by increased prostaglandin levels leading to uterine contractions. Amenorrhea (A) is the absence of menstruation, not painful cramps. Premenstrual syndrome (C) involves a variety of physical and emotional symptoms before menstruation, but not necessarily severe cramps. Abnormal uterine bleeding (D) refers to irregular or excessive bleeding, not specifically related to cramps.
Question 5 of 5
What type of medication would the nurse prepare to speak about with a patient recently diagnosed with endometriosis?
Correct Answer: A
Rationale: The correct answer is A: oral contraceptives. Oral contraceptives are commonly prescribed for managing endometriosis by regulating the menstrual cycle and reducing symptoms. They help control estrogen levels, which can alleviate pain and inflammation associated with endometriosis. Selective serotonin inhibitors (B) are used for treating depression and anxiety, not endometriosis. Dopamine agonists (C) are used for conditions like Parkinson's disease and hyperprolactinemia, not endometriosis. Bisphosphonates (D) are used to treat osteoporosis, not endometriosis. Therefore, oral contraceptives are the most appropriate medication to discuss with a patient diagnosed with endometriosis.
