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 ["B","C","E"]
Explanation
Choice A rationale
Lying down after meals can exacerbate heartburn by allowing stomach acid to flow back into the esophagus. It is generally recommended to remain upright after eating to help prevent this.
Choice B rationale
Remaining upright after meals helps prevent heartburn by keeping stomach acid in the stomach and reducing the likelihood of acid reflux. This can be achieved by sitting or standing for at least 30 minutes after eating.
Choice C rationale
Eating small, frequent meals can help prevent heartburn by reducing the amount of food in the stomach at any one time, which decreases the pressure on the stomach and the likelihood of acid reflux.
Choice D rationale
Drinking large amounts of water before meals can increase the volume in the stomach and may exacerbate heartburn. It is generally better to drink fluids between meals rather than before or during meals.
Choice E rationale
Discussing antacid recommendations with the provider is appropriate. Antacids can help neutralize stomach acid and provide relief from heartburn, but it is important to consult with a healthcare provider to ensure that the chosen antacid is safe for use during pregnancy.
Correct Answer is C
Explanation
Choice A rationale
This choice indicates G3-T1-P0-A1-L2. Gravida (G) is the total number of pregnancies, which is correct as 3. Term (T) is the number of pregnancies carried to term (37 weeks or more), which is 1. Preterm (P) is the number of pregnancies delivered between 20 and 36 weeks, which is 0. Abortions (A) is the number of pregnancies lost before 20 weeks, which is 1. Living (L) is the number of living children, which is 2. However, this choice incorrectly counts the preterm delivery as an abortion.
Choice B rationale
This choice indicates G3-T2-P0-A0-L2. Gravida (G) is correct as 3. Term (T) is the number of pregnancies carried to term, which is 2. Preterm (P) is the number of pregnancies delivered between 20 and 36 weeks, which is 0. Abortions (A) is the number of pregnancies lost before 20 weeks, which is 0. Living (L) is the number of living children, which is 2. This choice incorrectly counts the preterm delivery as a term delivery.
Choice C rationale
This choice indicates G3-T1-P1-A0-L2. Gravida (G) is correct as 3. Term (T) is the number of pregnancies carried to term, which is 1. Preterm (P) is the number of pregnancies delivered between 20 and 36 weeks, which is 1. Abortions (A) is the number of pregnancies lost before 20 weeks, which is 0. Living (L) is the number of living children, which is 2. This choice correctly accounts for the term and preterm deliveries.
Choice D rationale
This choice indicates G2-T1-P1-A0-L2. Gravida (G) is incorrect as it should be 3. Term (T) is the number of pregnancies carried to term, which is 1. Preterm (P) is the number of pregnancies delivered between 20 and 36 weeks, which is 1. Abortions (A) is the number of pregnancies lost before 20 weeks, which is 0. Living (L) is the number of living children, which is 2. This choice incorrectly counts the total number of pregnancies.
