A 24-year-old female agreed to participate in an 8-week research study for smoking cessation. After participating for 5 weeks, the woman tells the nurse she wants to withdraw from the study. The nurse’s best response is

  1. “You only have 3 weeks left in the study. Please don’t quit now.”
  2. “Unfortunately, you are obligated to complete the study.”
  3. “You have the right to stop at any time.”
  4. “I will speak with your physician and see if you can be released from the study early.”
Number 3 is correct.
Clients participating in research studies have the right to quit at any time and should be informed they are free to leave the study whenever they choose.
