A client expresses concern about teratogen exposure on fetal development.Which factor does the nurse emphasize as a priority related to the effects of teratogen exposure?
The mother’s size.
The timing and duration of exposure.
The type of teratogen.
The father’s health.
The Correct Answer is B
Choice A rationale
The mother’s size does not significantly impact the effects of teratogen exposure on fetal development. Teratogens are substances that cause congenital abnormalities in a developing fetus, and their impact is more related to the timing, duration, and type of exposure rather than the mother’s physical characteristics.
Choice B rationale
The timing and duration of exposure are critical factors in determining the effects of teratogen exposure. Teratogens can cause the most harm during specific periods of fetal development, particularly during the first trimester when organogenesis occurs. The duration of exposure also influences the severity of the effects, with prolonged exposure leading to more significant developmental issues.
Choice C rationale
The type of teratogen is also important, as different teratogens can cause different types of congenital abnormalities. For example, alcohol can lead to fetal alcohol syndrome, while certain medications can cause neural tube defects. However, the timing and duration of exposure are generally considered more critical factors.
Choice D rationale
The father’s health does not directly impact the effects of teratogen exposure on fetal development. Teratogens affect the fetus through the mother’s exposure to harmful substances during pregnancy.

Correct Answer is C
Explanation
Choice A rationale
Allowing the older sibling to hear the baby’s heartbeat at a prenatal visit can help them feel involved and connected to the new baby. This can be a positive experience and does not require follow-up by the nurse.
Choice B rationale
Enrolling the older sibling in a sibling preparation class at the hospital is a good way to prepare them for the arrival of the new baby. These classes often provide valuable information and help older siblings understand what to expect.
Choice C rationale
Bringing the new baby home as a surprise can be problematic. It may cause the older sibling to feel excluded or unprepared for the new addition to the family. It is important to involve the older sibling in the process and prepare them for the changes that will come with the new baby.
Choice D rationale
Allowing the older sibling to pick out a gift for the baby and having a gift for them from the baby can help foster a positive relationship between the siblings. This approach can make the older sibling feel valued and included.
Correct Answer is B
Explanation
Choice A rationale
Oligohydramnios refers to a condition where there is too little amniotic fluid. An amniotic fluid volume of 1900 mL is above the normal range, indicating that oligohydramnios is not present.
Choice B rationale
Polyhydramnios is the condition of having too much amniotic fluid. The normal range for amniotic fluid volume at 34 weeks gestation is between 800 and 1000 mL. An estimated volume of 1900 mL indicates polyhydramnios, which can be associated with various maternal and fetal conditions.
Choice C rationale
A follow-up glucose test is not directly indicated by the finding of polyhydramnios. While polyhydramnios can be associated with gestational diabetes, the decision to perform a glucose test would depend on other clinical factors and the patient’s history.
Choice D rationale
An amniotic fluid volume of 1900 mL is above the normal range for 34 weeks gestation, so it is not considered normal for gestational age. This finding indicates polyhydramnios rather than a normal fluid level.
