Final answer:
The appropriate nursing intervention for a pregnant client exposed to a teratogen in the 10th week of gestation is to collaborate with healthcare providers for additional monitoring and testing. B) Administer teratogenic medications
Step-by-step explanation:
When a pregnant client has been exposed to a teratogen in the 10th week of gestation, the nurse's plan of care should prioritize the health and development of the fetus. At this stage in gestation, the major organs are in the critical phase of development. The exposure to teratogens can adversely affect the development of the fetus depending on various factors such as the duration of teratogen exposure, the time of exposure, and the degree of transfer from maternal to fetal circulation.
Therefore, the most appropriate nursing intervention to include in the plan of care would be to collaborate with the healthcare provider for additional monitoring and testing. This collaboration can ensure that any potential complications or developmental issues are identified and managed as early as possible.
Continuous fetal heart rate monitoring and the administration of teratogenic medications are not appropriate interventions in this scenario, as the former may not directly address potential developmental issues, and the latter could harm the fetus. Educating the client about postpartum care, while important, does not address the immediate need for monitoring the effects of teratogen exposure.
