Anatomy and Physiology of the Female Breast Questions
Question 1 of 5
Which characteristic best describes the levator ani?
Correct Answer: B
Rationale: The correct answer is B: Collection of three pairs of muscles. The levator ani is a group of muscles in the pelvis that includes the puborectalis, pubococcygeus, and iliococcygeus muscles. These muscles provide support to the pelvic organs and play a role in bowel and bladder control. The other choices are incorrect because the levator ani is not related to the fallopian tube (A), an imaginary line dividing the true and false pelvis (C), or a basin-shaped structure at the lower end of the spine (D).
Question 2 of 5
The clinic nurse is reviewing breastfeeding with a pregnant patient. Which hormone will the nurse explain is responsible for milk production after the birth of the placenta?
Correct Answer: B
Rationale: The correct answer is B: Prolactin. Prolactin is the hormone responsible for milk production after the birth of the placenta. It stimulates the alveoli in the breast to produce milk. Pitocin (A) is responsible for uterine contractions. Estrogen (C) and progesterone (D) are involved in pregnancy maintenance but do not directly stimulate milk production.
Question 3 of 5
On speculum examination of the cervix, it is found to be round and smooth. These findings suggest that the patient
Correct Answer: D
Rationale: The correct answer is D: is nulliparous. A round and smooth cervix typically indicates that the patient has not given birth before (nulliparous). This is because after vaginal deliveries, the cervix may appear irregular or have scarring. Choice A is incorrect because being a multipar (having multiple births) would likely result in changes to the cervix after birth. Choice C is incorrect because previous vaginal deliveries would usually lead to changes in the cervix as well. Choice B is incomplete and does not provide any relevant information.
Question 4 of 5
The middle school nurse is reviewing the phases of the endometrial cycle with a group of female students. Which statement by a student will the nurse need to correct?
Correct Answer: A
Rationale: The correct answer is A. The proliferative phase occurs before ovulation when the endometrium thickens to prepare for implantation. This is not directly related to the maturation of the ovum. The other choices are incorrect because: B refers to ovulation, not expulsion of the ovum; C correctly states the secretory phase timing; D is incomplete.
Question 5 of 5
A 45-year-old patient asks how often she should have a mammogram. The most appropriate answer is
Correct Answer: B
Rationale: The correct answer is B: every year beginning at age 45. This recommendation aligns with guidelines from major health organizations, such as the American Cancer Society, which suggest annual mammograms for women starting at age 45 to screen for breast cancer. Regular screening helps detect early signs of cancer and improves treatment outcomes. Choice A is incorrect as relying on feeling a lump is not a reliable screening method. Choices C and D are incomplete and do not provide a specific guideline for mammogram frequency.
