A woman is 28 weeks pregnant with twins. The ultrasound reveals that one twin is a boy and the other is a girl. The woman asks if her babies will be identical. The nurse will base her answer upon which of the following information.

Genetic testing when the babies are delivered will need to be done to determine this.

They are dizygotic because the ultrasound shows one is bigger than the other.

The twins are dizygotic because they are not the same sex

They are monozygotic because they are in different amniotic sacs.

Answer and Explanation

The Correct Answer is C

A. Genetic testing is not necessary to determine if the twins are identical. Identical twins come from the same egg, while fraternal twins come from separate eggs.

B. The size difference alone does not determine whether twins are identical or fraternal.

C. Dizygotic twins (fraternal twins) are always of different sexes. This is because they are fertilized by two separate sperm and develop from two separate eggs.

D. Monozygotic twins (identical twins) occur when one fertilized egg splits into two embryos. The fact that they are different sexes rules out the possibility of monozygotic twins.

Correct Answer is {"dropdown-group-1":"B"}

Explanation

Given the client's symptoms of severe lower abdominal pain on the left side, the nurse should be concerned about a potential ectopic pregnancy, where the fertilized egg implants outside the uterus, commonly in the fallopian tube. This is a medical emergency, as it can lead to life-threatening complications if the tube ruptures.

A. Tell him to ignore the mood swings, as they will go away in a few days. B. Reassure him this behavior is normal following birth and is only a concern if it lasts more than two weeks. C. Tell him that his wife might need antidepressants and to call the provider. D. Advise him the baby unattended with his wife.

Correct Answer is B

Explanation

A. Ignoring the mood swings is not an appropriate response because it may be a sign of postpartum mood changes that need to be monitored.

B. Mood swings in the postpartum period are common and often due to hormonal changes. This is normal unless it persists beyond two weeks, at which point it may indicate postpartum depression.

C. Suggesting antidepressants immediately is premature; mood swings are common in the postpartum period, and treatment is not necessary unless they persist or worsen.

D. Advising the husband to leave the wife unattended is unsafe and inappropriate. Ensuring the wife has support during this time is important.
