The nurse is explaining the function of the placenta to a pregnant patient. Which statement indicates to the nurse that further clarification is necessary?

  • A. “My baby gets oxygen from the placent
  • B. “The placenta functions to help excrete waste products.”
  • C. “The nourishment that I take in passes through the placent
  • D. The placenta helps maintain a stable temperature for my baby.”
Correct Answer: D

Rationale: While the statement "The nourishment that I take in passes through the placenta" is generally correct in the context of the placenta providing nutrients to the fetus, it does not fully convey the process accurately. The primary function of the placenta is to facilitate the exchange of oxygen, nutrients, and waste products between the mother and the fetus through the mother's blood supply. It is not a direct passage of nourishment that the mother takes in; rather, it involves a complex process of diffusion and transport to ensure the fetus receives the necessary nutrients and oxygen. Therefore, further clarification is needed to ensure the patient has a complete understanding of this essential function of the placenta.
