The nurse is instructing a client who is at 10 weeks' gestation on smoking cessation and avoiding substance abuse because these substances will:
1. Interfere with hormone excretion of the fetus.
2. Stop the synthesis of protein in the developing fetus.
3. Pass into the developing fetus through the placenta very easily.
4. Facilitate the transfer of viruses and other diseases into the developing fetus.
3. Pass into the developing fetus through the placenta very easily.
Rationale:
Byproducts of smoking and substance use pass from the mother to the fetus through the placenta via simple diffusion. These substances have adverse effects on the developing fetus. Smoking byproducts and abused substances do not interfere with hormone excretion of the fetus or stop the synthesis of protein in the fetus. They do not facilitate the transfer of viruses and other diseases into the developing fetus.
