(1 pts.) Mrs. Johansen is pregnant and has accidentally been exposed to a person with German measles. She should be most concerned about the possibility of producing a child with mental retardation if she is in the
A) fetal period.
B) 35th week.
C) first trimester.
D) last trimester.
I'll be glad to check your answer.
To determine which period Mrs. Johansen should be most concerned about regarding the possibility of producing a child with mental retardation after being exposed to German measles, we need to consider the developmental stages of pregnancy.
German measles, also known as rubella, is a viral infection that can cause serious complications in pregnancy, especially during the early stages.
The developmental stages of pregnancy are divided into three trimesters:
1) First trimester: This is the period from conception to week 12. It is a critical period for the development of the baby's major organs and structures.
2) Second trimester: This is the period from week 13 to week 27. During this time, the baby's organs continue to develop, and they start growing and gaining weight.
3) Third trimester: This is the period from week 28 until birth. The baby's organs are fully developed, and they continue to grow and gain weight.
Now, considering the question, we want to determine which period is most concerning for the possibility of producing a child with mental retardation.
Since German measles can cause serious complications during early pregnancy, especially in the first trimester, the correct answer is:
C) First trimester.
Therefore, Mrs. Johansen should be most concerned about the possibility of producing a child with mental retardation if she is in the first trimester.
