A medication is described as having teratogenic side effects. The nurse understands that teratogenic is defined as which of the following?
A medication that causes harm to a fetus.
A medication that causes kidney damage.
A medication that acts in the opposite manner than expected.
A medication that causes an additive effect.
The Correct Answer is A
Teratogenic refers to an agent or factor that causes malformation of an embryo ¹. It is something that can interfere with normal fetal development and cause congenital disabilities ³. Drugs, alcohol, chemicals, and toxic substances are examples of teratogens ³.
Option B is not correct because teratogenic specifically refers to harm caused to a fetus, not kidney damage.
Option C is not correct because teratogenic does not refer to a medication acting in the opposite manner than expected.
Option D is not correct because teratogenic does not refer to a medication causing an additive effect.

Correct Answer is A
Explanation
The half-life of a medication is the time it takes for the concentration of the medication in the body to decrease by half. In this case, the medication has a half-life of 2 hours and a current toxic level of 40 mEq/dL. After 2 hours, the level will decrease to 20 mEq/dL. After another 2 hours (4 hours total), the level will decrease to 10 mEq/dL, which is within the normal range. However, it will take another 21 half-lives (42 hours) for the level to reach 5 mEq/dL, which is the lower end of the normal range. Therefore, it will take a total of 25 hours (4 + 21) for the medication to reach the normal range.
Option B is incorrect because it would take much longer than 24 hours for the medication to reach the normal range.
Option C is incorrect because it would only take 2 hours for the medication to decrease by half, not reach the normal range.
Option D is incorrect because it would take longer than 4 hours for the medication to reach the normal range.
Correct Answer is D
Explanation
Tolerance is a phenomenon that occurs when a person's body becomes accustomed to a medication over time. This means that the same dose of medication may no longer have the same effect as it did initially. In the case of anxiolytics, tolerance can mean that higher levels of medication are needed to achieve the expected effect. This is why
Option A refers to an increased ability to tolerate side effects, which is not the same as tolerance to the medication itself.
Option B suggests that a different medication is needed, but this is not necessarily the case when tolerance occurs.
Option C refers to greater acceptance of other people's behaviors, which is not related to tolerance to medication.
