Certified Advanced Alcohol and Drug Counselor (CAADC) Practice Exam

Referring a pregnant client to a medical doctor is the most appropriate choice, as this professional can provide comprehensive care tailored to the unique needs of the client and her pregnancy. A medical doctor can assess the health risks related to smoking during pregnancy and can advise on the safest and most effective methods to quit smoking. They can prescribe medications or recommend nicotine replacement therapies like patches or gum, while also taking into account the potential effects on the developing fetus.

In addition to quitting smoking, the medical doctor can provide prenatal care and monitor both the mother's health and the baby's development, which is crucial during this sensitive time. They are also equipped to address any medical complications that may arise from smoking or quitting, ensuring a holistic approach to the client’s health care needs.

While other options might offer some support—the pharmacy for nicotine replacement aids, social services for additional resources, and psychologists for behavioral therapy—they do not provide the integrated care and monitoring required during pregnancy that a medical doctor can deliver. This comprehensive oversight makes the medical doctor the best referral choice for a pregnant client wishing to quit smoking.
