Question

what does a class i drug recall signify?
the drug is being recalled due to cosmetic defects
the drug is being recalled due to minor labeling issues
the drug is being recalled because of a potential serious health risk or death
the drug is temporarily unavailable due to supply issues

Explanation:

In drug recalls, Class I recalls are the most serious. They are issued when a drug has a potential to cause serious health problems or death. Cosmetic defects or minor labeling issues are typically Class III or II, and supply issues aren't part of recall classification based on risk. So the correct option is the one about potential serious health risk or death.

Answer:

The drug is being recalled because of a potential serious health risk or death
