The nurse is providing education to a pregnant person regarding the nausea and vomiting of pregnancy. Identify the relief measures the nurse would discuss. Select all that apply.

Correct Answer: A

Rationale: The correct answer is A: avoid dairy products. This is because dairy products can exacerbate nausea in some pregnant individuals due to their high fat content. Avoiding dairy products can help reduce nausea symptoms. Rationale: 1. Avoiding dairy products: High fat content in dairy products can trigger nausea in some pregnant individuals. 2. Avoid strong odors: While strong odors can trigger nausea, it is not a specific relief measure for nausea and vomiting of pregnancy. 3. Drink fluids between meals: Staying hydrated is important, but drinking fluids between meals is not a specific relief measure for nausea and vomiting of pregnancy. 4. Drink sweet fluids: While some pregnant individuals find relief from nausea by consuming sweet fluids, it is not a universal recommendation and may not work for everyone.

Correct Answer: B

Rationale: The correct answer is B because infants born at 25 weeks' gestation have a poor survival rate due to insufficient numbers of fetal lung alveoli. This leads to respiratory distress and difficulty in oxygen exchange, impacting their chances of survival. Choice A is incorrect as cardiac development is not the primary factor affecting survival. Choice C is incorrect as gastrointestinal development does not directly impact survival at this stage. Choice D is incorrect as the sucking reflex is not a critical factor in survival compared to respiratory function.

Correct Answer: C

Rationale: The correct answer is C: neonatal intensive care. This is because during a home birth, neonatal intensive care is not provided as it requires specialized medical equipment and expertise typically only available in hospitals. Labor support (A) and trained birth attendant (B) are essential for home births. Breastfeeding assistance (D) may be provided post-birth but is not a defining feature of care during a home birth.

Correct Answer: A

Rationale: The correct answer is A: The zona reaction. After fertilization, the zona pellucida undergoes a biochemical change called the zona reaction, which makes the ovum impenetrable to any other sperm. This process prevents polyspermy and ensures that only one sperm can fertilize the egg. Gametogenesis refers to the production of gametes, not the post-fertilization event. The zona pellucida is the glycoprotein layer around the ovum, and cleavage is the rapid mitotic cell division that follows fertilization, but neither of these directly relate to the ovum becoming impenetrable to other sperm.

Correct Answer: C

Rationale: Conjoined twins are formed at about 13 to 15 days after conception when the embryonic disc undergoes incomplete splitting. At this stage, the cells have already differentiated into different layers, making separation challenging. Immediately after fertilization (choice A) is too early for conjoined twins to form. At the time of implantation (choice B) is when the blastocyst implants into the uterine wall, but conjoined twins are not formed at this point. In the blastocyst stage (choice D), the cells are still in the process of organizing and have not yet differentiated into distinct layers. Therefore, choice C is the correct answer as it aligns with the timing of conjoined twin formation during embryonic development.
