Health Promotion and MaintenanceQuestion 1950 of 2368
A client at five weeks of gestation asks why avoiding hazardous agents matters now. Which response is best?
- The organs are fully formed, so exposure now affects only fetal growth later
- Hazardous agents matter only later, once the fetus begins to move in the womb
- The placenta blocks all hazardous agents from reaching the embryo at this stage
- The organs are forming, so exposure now raises the risk of malformations in any system
Show answer
Correct answer: The organs are forming, so exposure now raises the risk of malformations in any system
Exposure to teratogens during organogenesis increases the risk of malformations in all systems of the embryo’s body.
