question 2\na study requires that each subject be given two study drugs. the first study drug is given on day 1. a second study drug is given on day 7 to counteract the toxicity of drug 1. subject # 4 - 706 is given drug 1 on day 1. due to a snowstorm, subject 4 - 706 is delayed for several days before returning to the site for drug 2. missing the administration of drug 2 on day 7 placed the subject at risk of significant toxicity. this event required the subject be notified of the increased risk and required close monitoring of the subject by phone.\nthis is an adverse event, which does not require notification to the irb.\nthis is not an unanticipated problem because the subject was required to return on day 7.\nthis is an unanticipated problem that does not include an adverse event.\nthis is not an unanticipated problem because adverse weather is a possibility in the area where the site is located.

Answer

Brief Explanations:

An unanticipated problem is one that was not expected in the study design. Here, the snow - storm causing delay in drug 2 administration and increased toxicity risk was an unforeseen event. An adverse event is an untoward medical occurrence in a subject. Since the subject was at risk of significant toxicity due to the delay, it is an adverse event. Such events that pose risks to subjects typically need to be reported to the Institutional Review Board (IRB).

Answer:

None of the provided options are correct. This is an unanticipated problem that includes an adverse event and likely requires notification to the IRB.
