Answer: both safe and effective.
Explanation:
In 1962, there was a drug in Europe and Canada that was meant to treat morning sickness in pregnant women. The drug instead caused birth defects in many people.
The Federal government of the US decided that it would be best to take action against that drug and others like it from harming the U.S. like it did those other countries.
This action came in the form of the Kefauver-Harris amendment to the Federal Food, Drug and Cosmetic (FD&C) Act. According to this amendment, companies manufacturing drugs had to make sure that a drug was not only safe for consumption, but effective in treating what it is meant to treat as well.
A patient and nurse can effectively interact and communicate when that patient has a tracheostomy thorugh "lip - reading", this is one ability that the nurse must have in order for him/her to understand the patient. Other devices such as speaking valves are implemented to allow the patients to talk freely.
