Answer to Question 1

D

Answer to Question 2

This is a convenience sample. Undercoverage might result. Those in the breakroom might not represent the full range of employee types, experiences, stress levels, or access to the hospital's drug supply. Pharmacy workers, for example, have greater access to drugs, and may have higher proportions of drug use than other workers, causing too high an estimate of the drug problem.
