The nurse is providing discharge instructions to a person who was evaluated for possible labor. How does the nurse explain how losing the mucus plug could be a sign of impending labor?

Correct Answer: A

Rationale: The correct answer is A because the mucus plug is expelled due to increased estrogen levels before contractions start. Estrogen stimulates the production of mucus that forms the plug, which is then released as a result of hormonal changes signaling the body to prepare for labor. This process occurs before labor contractions begin. Choice B is incorrect because the mucus plug is typically expelled before the membranes rupture during labor. Choice C is incorrect because effacement and dilation of the cervix do not directly cause the expulsion of the mucus plug. Choice D is incorrect because labor can begin even if the mucus plug has not been expelled, and the plug itself does not create a space for the fetus.

Correct Answer: C

Rationale: The correct answer is C because the expected length of the third stage of labor, which is the delivery of the placenta, is typically around 1 hour for a multiparous person (someone who has given birth before) and around 2 hours for a nulliparous person (someone who is giving birth for the first time). This is based on the normal physiological process of the uterus contracting to expel the placenta. Choice A and B are incorrect as they provide specific time limits that are not generally applicable to all individuals. Choice D is incorrect as it suggests longer durations which are beyond the typical range for the third stage of labor.

Correct Answer: D

Rationale: The correct answer is D because during labor, progesterone levels decrease, estrogen levels increase, and oxytocin plays a key role in initiating contractions. Progesterone inhibits contractions, so its decrease is necessary for labor to start. Estrogen helps stimulate uterine contractions. Oxytocin, released from the brain, triggers and enhances contractions. Option A is incorrect because an absence of oxytocin would not initiate labor. Option B is incorrect because increased progesterone would inhibit labor. Option C is incorrect because oxytocin is needed to initiate labor.

Correct Answer: E

Rationale: Failed to generate a rationale of 500+ characters after 5 retries.

Correct Answer: D

Rationale: The correct answer is D because it addresses the potential strains on relationships that can occur after the birth of a child. New parents often experience changes in their relationship dynamics due to increased responsibilities, sleep deprivation, and shifts in priorities. By preparing them for these possible strains, the nurse can help them navigate these challenges effectively. A is incorrect because roles often do change at home with the arrival of a newborn. B is incorrect as stresses can actually increase after the baby is born. C is incorrect as it dismisses the importance of addressing household changes and potential stressors.
