A nurse in a prenatal clinic overhears a newly licensed nurse discussing conception with a client.
Which of the following statements by the newly licensed nurse requires intervention by the nurse?
A.
“Bleeding or spotting can accompany implantation.”.
B.
“Sperm remains viable in the woman’s reproductive tract for 2 to 3 days.”.
C.
“Fertilization takes place in the outer third of the fallopian tube.”.
D.
“Implantation occurs between two and three weeks after conception.”
The correct answer and Explanation is :
The correct answer is D. “Implantation occurs between two and three weeks after conception.”
This statement requires intervention because it is incorrect. In reality, implantation occurs much earlier, typically between 6 and 10 days after fertilization, not two to three weeks. Here’s a more detailed explanation of the key points involved:
Fertilization
Fertilization occurs when a sperm cell successfully penetrates an egg, usually within the outer third of the fallopian tube, also known as the ampulla. This is correctly reflected in option C, making it a correct statement.
Sperm Viability
Once sperm is ejaculated into a woman’s reproductive tract, it can remain viable and capable of fertilizing an egg for 2 to 3 days, as mentioned in option B. This is also accurate, as the sperm can survive for that duration, waiting for ovulation and fertilization to occur.
Implantation
After fertilization, the fertilized egg (zygote) travels down the fallopian tube over the course of a few days, transforming into a blastocyst. Implantation, which is the attachment of the blastocyst to the lining of the uterus, typically happens 6 to 10 days after fertilization. By this time, the endometrium (uterine lining) has prepared to nourish the embryo.
The newly licensed nurse’s statement in option D is incorrect because implantation does not take place two to three weeks after conception. This misconception can lead to misunderstandings regarding pregnancy progression and cause confusion for clients about when early pregnancy symptoms might begin.
Bleeding or Spotting
Spotting or light bleeding can occur when the blastocyst implants in the uterine lining. This is known as implantation bleeding and usually occurs around the same time as implantation. Therefore, option A is also correct.
In conclusion, statement D is the one that requires intervention due to its inaccuracy.
