Anatomy and Physiology of the Female Breast Questions
Question 1 of 5
A postpartum patient who has had a vaginal birth asks the nurse, I was wondering if my cervix will return to its previous shape before I had the baby? Which is the best response by the nurse?
Correct Answer: A
Rationale: The correct answer is A: The cervix will now have a slit-like shape. After giving birth, the cervix undergoes changes in shape and size to adapt to the delivery process. It becomes slit-like instead of round to allow for easier dilation in future pregnancies. This response is correct as it addresses the anatomical changes that occur postpartum. Choice B is incorrect because it does not provide an explanation of the postpartum cervix shape changes. Choice C is incorrect because it describes the cervix in a way that does not reflect the usual postpartum changes. Choice D is incorrect because it refers to effacement, which is the thinning of the cervix during labor and not a permanent change postpartum.
Question 2 of 5
A patient states, My breasts are so small. I don’t think I will be able to breastfeed my baby. Which is the nurse’s best response?
Correct Answer: D
Rationale: Rationale: - Choice D is correct as it provides accurate information that all women have sufficient glandular tissue for milk secretion, regardless of breast size. - Breast size does not determine breastfeeding ability. - Choices A and B lack evidence-based information and may discourage the patient or lead to misinformation.
Question 3 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 4 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 5 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.
