Question 2 of 5
What is the purpose of the ovum’s zona pellucida?
Correct Answer: A
Rationale: The zona pellucida is a protective layer surrounding the ovum (egg cell). One of its primary functions is to prevent multiple sperm from fertilizing the egg by only allowing one sperm to penetrate and fertilize the ovum. This is crucial for ensuring that the resulting embryo has the correct genetic material (46 chromosomes) and does not have an abnormal number of chromosomes, which could lead to developmental issues. The zona pellucida acts as a physical barrier that helps to maintain the genetic integrity of the offspring.
Question 3 of 5
A patient who is 16 weeks pregnant with her first baby asks how long it will be before she feels the baby move. Which is the nurse’s best answer?
Correct Answer: D
Rationale: Maternal perception of fetal movement (quickening) usually begins between 17 and 20 weeks after conception. Because this is her first pregnancy, movement is felt toward the later part of the 17 to 20 weeks. “The baby is moving, but you can’t feel it yet” may be alarming to the woman. “Some babies are quiet and you don’t feel them move” is a true statement; the fetus’ movements are not strong enough to be felt until 17 to 20 weeks; however, this statement does not answer the woman’s concern. Fetal movement should be felt between 17 and 20 weeks; if movement is not perceptible by the end of that time, further assessment will be necessary.
Question 4 of 5
The nurse is explaining the function of the placenta to a pregnant patient. Which statement indicates to the nurse that further clarification is necessary?
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.
