Question 2 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 3 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 4 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 5 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.
