The part that is not required for obtaining informed consent in a research setting is explaining the study’s hypothesis to participants.

Quick Scoop: Core Idea

Informed consent focuses on ensuring that participants:

  • Know participation is voluntary and they can withdraw at any time.
  • Understand what will happen to them, including procedures, risks, and benefits.
  • Are told how their data will be handled, including confidentiality.
  • Provide documented agreement, often via a signed consent form (or parent/guardian signature for minors).

Common exam-style options usually include:

  1. Explaining the hypothesis to the participants.
  2. Letting participants know participation is voluntary.
  3. Getting the participant’s (or guardian’s) signature.
  4. Reviewing that data is confidential.

Among these, explaining the hypothesis is good practice but not a required element of informed consent, whereas voluntariness, signatures (documentation), and confidentiality are core elements.

So if you see the multiple‑choice question “which of the following is not part of obtaining informed consent?”, the correct answer is:
Explaining the hypothesis to the participants.

TL;DR: Informed consent must cover procedures, risks/benefits, voluntariness, and confidentiality, and be documented, but does not have to include a detailed explanation of the study’s hypothesis.
