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
Explanation
Choice A rationale
Lisinopril is not a beta blocker; it is an ACE inhibitor. Beta blockers, such as metoprolol, are generally considered safer during pregnancy compared to ACE inhibitors. Beta blockers work by blocking the effects of adrenaline on your heart and blood vessels, which helps to lower blood pressure. However, they are not without risks and should be used under medical supervision during pregnancy.
Choice B rationale
Lisinopril is an ACE inhibitor, which is contraindicated during pregnancy, especially in the second and third trimesters. ACE inhibitors can cause fetal renal dysfunction, oligohydramnios, and even fetal death. Therefore, it is essential to discuss alternative medications that are safer during pregnancy.
Choice C rationale
This statement is incorrect because ACE inhibitors, including lisinopril, are not safe to continue during pregnancy. They pose significant risks to the fetus, particularly in the later stages of pregnancy.
Choice D rationale
Lisinopril is not an angiotensin II receptor blocker (ARB); it is an ACE inhibitor. ARBs, like ACE inhibitors, are also contraindicated during pregnancy due to similar risks of fetal toxicity and adverse outcomes.
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.
