A nurse is reinforcing teaching with a newly licensed nurse about embryonic nutrition.
Which of the following statements by the newly licensed nurse indicates an understanding of the teaching?
Prior to the development of the placenta, the amnion provides nutrients.
The chorion supports development of the embryo.
The allantois will work to provide nutrients prior to the development of the placenta.
The yolk sac provides nutrients to the developing embryo.
The Correct Answer is D
Choice A rationale
The amnion is a membrane that encloses the amniotic fluid but does not provide nutrients to the embryo.
Choice B rationale
The chorion forms part of the placenta and contributes to nutrient and gas exchange once the placenta develops, but it does not provide nutrients before the placenta forms.
Choice C rationale
The allantois is involved in early fluid exchange and waste management but does not provide nutrients before the placenta forms.
Choice D rationale
The yolk sac provides nutrients to the developing embryo before the placenta is fully functional, supporting early embryonic development.

Correct Answer is D
Explanation
Choice A rationale
In pregestational type 1 diabetes mellitus, insulin needs typically decrease during the first trimester due to increased insulin sensitivity and decreased food intake from nausea and vomiting, not an increased dosage.
Choice B rationale
Hypotension is not a typical finding associated with pregestational type 1 diabetes mellitus. Instead, hyperglycemia and its complications, such as ketoacidosis, are more relevant concerns.
Choice C rationale
While weight gain is monitored in diabetic pregnancies, excessive weight gain is not a specific condition associated with pregestational type 1 diabetes mellitus. Weight management should be appropriate to avoid complications.
Choice D rationale
Polyphagia, or increased hunger, is a symptom associated with diabetes mellitus due to the body's inability to properly utilize glucose, leading to increased appetite and higher blood glucose levels.
Correct Answer is B
Explanation
Choice A rationale
Checking the client's temperature every 4 hours is important to monitor for infection but is not the primary action during the active phase of labor following an amniotomy.
Choice B rationale
Encouraging the client to empty the bladder every 2 hours helps prevent bladder distention, which can impede the descent of the baby and contribute to labor progress.
Choice C rationale
Bearing down with each contraction is advised during the second stage of labor, not the active phase of the first stage.
Choice D rationale
Maintaining the client in the lithotomy position is not necessary throughout labor and can be uncomfortable; mobility and changing positions are encouraged.
