Question 1An investigator is confronted with a life-threatening situation that necessitates using a test article in a human subject who is unable to provide informed consent and there is no time to obtain consent from the individual’s LAR and no alternative method or recognized therapy is available. Under the FDA regulations for using test articles, which of the following describes the best course of action for the investigator: The investigator and an independent physician agree that the situation necessitates the use of the test article. An exception or waiver for informed consent can be made under these circumstances. The IRB will be notified later. Use the test article without obtaining consent from the subject or the LAR then notify the IRB. Do not use the test article until either the subject or the subject's LAR can give consent. Submit a research protocol to the IRB and justify an expedited review approval of the consent document so test article can be used immediately.Question 2The purpose of informed consent is: To provide a potential subject with appropriate information in an appropriate manner and allow that person to make an informed decision about participation in research. To document the investigator's participation in the consent process. To obtain a signature from a study subject in order to document his or her agreement to participate in research. To obtain a signature from a study subject in order to protect the investigator, the study staff and the institution.Question 3A general requirement for the informed consent form is that it may not include any exculpatory language. Exculpatory language is that which waives or appears to waive any of the subject's legal rights or releases or appears to release those conducting the research from liability for negligence. Which of the following statements in a consent form is an example of exculpatory language? The investigator may stop you from participating in this research without your consent if you experience side effects that make your condition worse. If you become ill during the research, you may have to drop out. Your participation in this research is voluntary. If you choose not to participate, or change your mind later, your decision will not affect your relationship with your doctor or your right to health care or other services that you may be eligible for. I waive any possibility of compensation for injuries that I may receive as a result of participation in this research. In the event of any injury you may have related to this research, you will be given medical treatment.Question 4A 46-year-old man is currently enrolled in a Phase 2 study of a drug for severe diabetic neuropathy. While the study is on-going, a new drug becomes commercially available that may have equal or greater benefit to the subject. The investigator should do which of the following? Do not tell the subject about the new drug because physicians have the right to try out new treatments with their patients. Give the subject comprehensive information about the new drug, including its side effects. Discuss the pros and cons of both the investigational drug and the commercially available drug and then allow the subject to decide whether to withdraw from the research to take the new drug. Tell the subject about the new drug but discourage him from switching treatments until the study is completed. Withhold this new information to avoid confusing the subject with other treatment options or alternatives.Question 5An elderly gentleman, whose wife is his legally authorized representative (LAR) since his strokes several years ago, was recently diagnosed with lung cancer. He is eligible for a clinical trial using a new investigational drug that aims to treat lung cancer. He is able to express interest, shows a basic understanding of the nature of the trial, and gives his assent to participation. The subject's wife is out of town on a business trip.Which of the following is the most appropriate action to take for the investigator? Send a copy of the informed consent via facsimile to the subject's wife. After she has had the opportunity to speak to the investigator, she can sign the informed consent and fax it back. Exclude the man from the study. The investigator can go ahead and enroll the man without a signed consent. Consult a colleague about his opinion. If the colleague agrees, enroll the man without a signed consent.
