A Nurse Notes That in Clients with Multiple Tattoos, Many

question 1

Multiple Choice

A nurse notes that in clients with multiple tattoos, many are missing quite a few of their teeth. The nurse measures the variables and establishes a negative correlation between number of tattoos and number of teeth. The nurse designs a study to measure causation. Why is this problematic?

• A)Tattooing can be expensive.
• B)Causing subjects to become multiply tattooed, so as to cause their teeth to fall out, is ethically questionable.
• C)Random assignment to group would be impossible.
• D)The nurse researcher cannot cause subjects' teeth to fall out, so as to later measure if their number of tattoos has increased; that would be ethically questionable.
• E)The study would have to be designed as a large-sample, multisite design.
