Authorship
Medium
A.Gift (honorary) authorship
B.Ghost authorship
C.Co-first authorship
D.Corresponding authorship
Correct Answer: Gift (honorary) authorship
Explanation:
Adding someone as an author based on status rather than contribution is gift or honorary authorship, an ethical violation. Ghost authorship is the opposite—omitting a genuine contributor.
Incorrect! Try again.

39A physician withholds a life-sustaining treatment at a terminally ill, competent patient's explicit request, allowing the natural course of disease. This is best classified as:
Euthanasia
Medium
A.Active involuntary euthanasia
B.Passive voluntary euthanasia
C.Non-voluntary active euthanasia
D.Physician-assisted homicide
Correct Answer: Passive voluntary euthanasia
Explanation:
Withholding treatment at a competent patient's request is passive (allowing death rather than causing it directly) and voluntary (patient consents), distinguishing it from active or involuntary forms.
Incorrect! Try again.
40What key ethical distinction separates active euthanasia from passive euthanasia?
Euthanasia
Medium
A.Active applies only to animals and passive only to humans
B.Active involves a deliberate act to cause death, passive involves withholding or withdrawing treatment
C.Active requires no consent while passive requires a court order
D.Active is always legal while passive is always illegal
Correct Answer: Active involves a deliberate act to cause death, passive involves withholding or withdrawing treatment
Explanation:
Active euthanasia is a positive action intended to end life, whereas passive euthanasia involves letting a patient die by withholding or withdrawing life-sustaining treatment.
Incorrect! Try again.
41A study proposes minimal-risk retrospective analysis of de-identified hospital records. The investigator argues it should be exempt from IRB review. Under the Common Rule, which factor most critically determines whether continuing IRB oversight (expedited vs. exempt) is warranted?
Institutional Review Board (IRB) and its functions
Hard
A.Whether the sample size exceeds 1000 records
B.Whether identifiable private information could be readily traced back to individuals
C.Whether the results will be published in a peer-reviewed journal
D.Whether the study is funded by a federal agency
Correct Answer: Whether identifiable private information could be readily traced back to individuals
Explanation:
Exemption hinges on whether human subjects are identifiable. If data are truly de-identified and cannot be linked back, exemption may apply; if re-identification is feasible, IRB oversight (at least expedited) is required. Funding, sample size, and publication venue do not determine exemption status.
Incorrect! Try again.
42In a Phase I oncology trial, participants have advanced disease with no standard options. The therapeutic dose is unknown and toxicity is expected. Which principle best justifies enrollment despite an unfavorable individual risk-benefit ratio?
Risks and benefits
Hard
A.The obligation to maximize enrollment to accelerate approval
B.The requirement that risks be entirely eliminated before enrollment
C.The prospect of generalizable knowledge combined with informed, autonomous consent
D.The certainty that participants will directly benefit clinically
Correct Answer: The prospect of generalizable knowledge combined with informed, autonomous consent
Explanation:
Phase I trials rarely offer direct benefit; ethical justification rests on societal value (generalizable knowledge) and genuinely informed, voluntary consent that acknowledges the low probability of personal benefit. Risks cannot be fully eliminated, direct benefit is not guaranteed, and maximizing enrollment is not an ethical justification.
Incorrect! Try again.
43A trial seeks to enroll incarcerated individuals for a study on a chronic disease unrelated to imprisonment. Which condition would most clearly render this ethically permissible under regulations governing prisoner research?
Vulnerable populations
Hard
A.The research concerns conditions affecting prisoners as a class and offers no undue inducement
B.The prisoners receive substantial payment improving their prison standing
C.The prison administration approves for operational convenience
D.The study requires no external IRB because prisons are self-regulating
Correct Answer: The research concerns conditions affecting prisoners as a class and offers no undue inducement
Explanation:
Special protections require that research involving prisoners fall into permitted categories (e.g., conditions affecting them as a class) and that incentives not be so large as to coerce given the constrained environment. Administrative convenience, standing-enhancing payments, and self-regulation are not valid justifications.
Incorrect! Try again.
44A senior lab head provided funding and lab space but did not contribute intellectually to a manuscript's design, analysis, or writing. Per ICMJE criteria, the appropriate action is to:
Authorship
Hard
A.List them as corresponding author regardless of contribution
B.Omit any mention to avoid conflicts of interest
C.List them as first author due to seniority
D.Acknowledge the contribution but not list them as an author
Correct Answer: Acknowledge the contribution but not list them as an author
Explanation:
ICMJE requires all four criteria including substantial intellectual contribution, drafting/revising, final approval, and accountability. Providing resources alone does not qualify for authorship; such contributions belong in the acknowledgments. Listing them as author would constitute gift/honorary authorship.
Incorrect! Try again.
45The '14-day rule' historically limits in vitro culture of human embryos. What is the primary developmental rationale underlying this specific threshold?
Ethical issues in human cloning reproduction and stem cells research
Hard
A.The onset of the primitive streak, marking individuation and the end of possible twinning
B.The point of implantation in the uterine wall
C.The completion of neural tube closure
D.The first heartbeat detectable by ultrasound
Correct Answer: The onset of the primitive streak, marking individuation and the end of possible twinning
Explanation:
Around day 14 the primitive streak appears, signaling the beginning of individuation (a single individual can no longer split into twins) and gastrulation. This developmental milestone, not heartbeat, neural closure, or implantation, underpins the moral significance of the 14-day boundary.
Incorrect! Try again.
46A competent terminally ill patient requests that a physician withdraw a life-sustaining ventilator, knowing death will follow. Ethically and legally, this is most accurately classified as:
Euthanasia
Hard
A.Involuntary euthanasia
B.Active voluntary euthanasia
C.Passive euthanasia / withdrawal of treatment respecting autonomy
D.Physician-assisted suicide
Correct Answer: Passive euthanasia / withdrawal of treatment respecting autonomy
Explanation:
Withdrawing unwanted life-sustaining treatment at a competent patient's request is withholding/withdrawal (often termed passive euthanasia) grounded in the right to refuse treatment. It differs from active euthanasia (administering a lethal agent) and assisted suicide (providing the means for the patient to end their own life).
Incorrect! Try again.
47A placebo-controlled trial is proposed for a new antihypertensive where effective standard treatment already exists. Under the Declaration of Helsinki, using a placebo arm is most defensible only when:
Ethical issues in clinical research
Hard
A.No proven intervention exists, or compelling methodological reasons justify it without serious harm risk
B.The sponsor requires it for faster regulatory approval
C.The placebo arm reduces trial costs significantly
D.Participants are unaware they might receive placebo
Correct Answer: No proven intervention exists, or compelling methodological reasons justify it without serious harm risk
Explanation:
Helsinki permits placebo only when no proven intervention exists, or where compelling scientific reasons exist and patients receiving placebo will not be subject to serious or irreversible harm. Cost, concealment, and regulatory speed do not ethically justify withholding effective treatment.
Incorrect! Try again.
48A researcher publishes gain-of-function methods that enhance pathogen transmissibility, citing scientific openness. This scenario best illustrates which ethical tension central to 'dual-use research of concern' (DURC)?
Social and ethical implications of biological weapons
Hard
A.Confidentiality versus the duty to warn identifiable third parties
B.Freedom of scientific inquiry versus prevention of misuse and public safety
C.Distributive justice versus beneficence in resource allocation
D.Individual autonomy versus informed consent
Correct Answer: Freedom of scientific inquiry versus prevention of misuse and public safety
Explanation:
DURC captures the tension between open dissemination of beneficial knowledge and the risk that the same information enables bioweapon development. The core conflict is scientific freedom/openness versus biosecurity and public safety, not consent, allocation, or confidentiality issues.
Incorrect! Try again.
49The Belmont principle of 'respect for persons' has two distinct components. When enrolling a patient with early-stage dementia who has fluctuating capacity, which action best honors both components?
Human protectionism
Hard
A.Excluding all cognitively impaired individuals from any research
B.Obtaining consent during lucid periods while providing additional protections such as a legal representative
C.Relying solely on a family member's decision without assessing the patient's wishes
D.Proceeding based on the patient's original consent regardless of later capacity loss
Correct Answer: Obtaining consent during lucid periods while providing additional protections such as a legal representative
Explanation:
Respect for persons requires honoring autonomy (seeking the individual's own consent when able) and protecting those with diminished autonomy (added safeguards). Combining lucid-period consent with a legal representative satisfies both. Blanket exclusion, ignoring the patient, or relying only on stale consent fails one component.
Incorrect! Try again.
50An investigator discovers that a co-author fabricated part of a dataset after publication. Which sequence of actions best conforms to responsible conduct of research?
Issues in research ethics
Hard
A.Ignore it since the paper is already published
B.Notify the institution's research integrity officer and initiate correction or retraction of the publication
C.Publicly accuse the co-author on social media immediately
D.Quietly remove the co-author's name from future work
Correct Answer: Notify the institution's research integrity officer and initiate correction or retraction of the publication
Explanation:
Suspected fabrication must be reported through proper institutional channels (research integrity officer), triggering investigation and, if confirmed, correction or retraction to preserve the scientific record. Silent removal, inaction, or public accusation bypass due process and fail the duty to maintain integrity.
Incorrect! Try again.
51During continuing review, an IRB learns of an unanticipated serious adverse event that shifts the risk-benefit balance unfavorably. The IRB's most appropriate immediate authority is to:
Institutional Review Board (IRB) and its functions
Hard
A.Suspend or terminate approval and require re-consent or protocol modification
B.Refer the matter solely to the funding agency for a decision
C.Delegate the decision entirely to the sponsor
D.Wait until the scheduled annual review to act
Correct Answer: Suspend or terminate approval and require re-consent or protocol modification
Explanation:
IRBs have authority to suspend or terminate approval of research not conducted in accordance with requirements or that has caused unexpected serious harm, and to require modifications or re-consent. Deferring to funders or sponsors, or waiting for annual review, abdicates the IRB's protective role.
Incorrect! Try again.
52In international research conducted in a low-income country, offering free healthcare that participants could never otherwise access raises concern about:
When benefits like otherwise-inaccessible care are so attractive that they distort judgment about risks, they constitute undue inducement, undermining truly voluntary consent especially among economically vulnerable populations. The issue concerns consent voluntariness, not placebos, authorship, or registration.
Incorrect! Try again.
53Induced pluripotent stem cells (iPSCs) are often cited as sidestepping a key ethical objection to embryonic stem cells. Which objection do they primarily circumvent?
Ethical issues in human cloning reproduction and stem cells research
Hard
A.The need for informed consent from donors
B.The destruction of human embryos to derive stem cells
C.The problem of immune rejection after transplantation
D.The risk of teratoma formation in transplants
Correct Answer: The destruction of human embryos to derive stem cells
Explanation:
iPSCs are reprogrammed from adult somatic cells, so their derivation does not require destroying embryos, the central moral objection to embryonic stem cells. Consent is still needed, and teratoma risk and (in allogeneic cases) rejection remain scientific concerns rather than the objection iPSCs resolve.
Incorrect! Try again.
54The doctrine of double effect is invoked to justify palliative sedation that may hasten death. For the doctrine to apply, which condition is essential?
Euthanasia
Hard
A.The physician intends the patient's death to relieve suffering
B.The patient explicitly requests a lethal dose
C.The lethal outcome is the direct means of achieving relief
D.The intended effect is symptom relief and death is a foreseen but unintended consequence
Correct Answer: The intended effect is symptom relief and death is a foreseen but unintended consequence
Explanation:
Double effect permits an action with a good intended effect (relieving suffering) even if a harmful effect (death) is foreseen, provided death is not intended and not the means to the good effect. If death is intended or used as the means, the doctrine no longer applies.
Incorrect! Try again.
55An IRB is evaluating a pediatric study with no prospect of direct benefit to child participants. Under the 'minor increase over minimal risk' standard, approval additionally requires that:
Risks and benefits
Hard
A.The children provide fully informed adult-level consent
B.Parents waive all liability on behalf of the child
C.The research is likely to yield vital knowledge about the subjects' disorder or condition
D.The intervention offers a guaranteed therapeutic benefit
Correct Answer: The research is likely to yield vital knowledge about the subjects' disorder or condition
Explanation:
For a minor increase over minimal risk with no direct benefit, regulations require that the intervention be commensurate with the child's situation and likely to yield generalizable knowledge of vital importance about the disorder/condition. Liability waivers, adult consent, and guaranteed benefit are not the operative criteria.
Incorrect! Try again.
56Two researchers dispute the order of authorship on a collaborative paper where contributions were roughly equal. Which mechanism most appropriately resolves this within accepted publishing norms?
Authorship
Hard
A.Designating co-first authorship with an equal-contribution footnote
B.Assigning first authorship to the more senior researcher automatically
C.Alphabetical ordering imposed by the journal editor
D.Excluding one author to avoid the dispute
Correct Answer: Designating co-first authorship with an equal-contribution footnote
Explanation:
When contributions are genuinely equal, journals accept co-first authorship denoted by an equal-contribution statement. Defaulting to seniority ignores actual contribution, editors do not impose ordering, and excluding a legitimate contributor would be misconduct.
Incorrect! Try again.
57The Biological Weapons Convention (BWC) is often criticized for a structural weakness compared to the Chemical Weapons Convention. This weakness is:
Social and ethical implications of biological weapons
Hard
A.The lack of any signatory states
B.The absence of a formal verification and inspection mechanism
C.The permission to stockpile pathogens for defense
D.The failure to ban offensive research entirely
Correct Answer: The absence of a formal verification and inspection mechanism
Explanation:
Unlike the CWC, the BWC lacks a legally binding verification/inspection regime, making compliance difficult to confirm. It does prohibit development and stockpiling for offensive purposes and has many signatories, so the acknowledged gap is verification, not scope or membership.
Incorrect! Try again.
58A trial's data safety monitoring board (DSMB) observes at interim analysis that the experimental arm shows overwhelming benefit exceeding a pre-specified stopping boundary. The ethically indicated action is to:
Ethical issues in clinical research
Hard
A.Unblind only the sponsor and continue enrollment
B.Switch the control arm to a placebo
C.Continue to the planned end for maximal statistical power
D.Recommend early termination so all participants can access the effective treatment
Correct Answer: Recommend early termination so all participants can access the effective treatment
Explanation:
When a pre-specified efficacy stopping boundary is crossed, continuing to randomize participants to the inferior arm becomes unethical (equipoise is lost). The DSMB should recommend stopping so participants gain access to the beneficial treatment. Pursuing power at participants' expense violates beneficence.
Incorrect! Try again.
59The Tuskegee Syphilis Study is a foundational case in research ethics. Its most egregious violation, which directly shaped later protections, was:
Human protectionism
Hard
A.Paying participants excessive incentives
B.Withholding available effective treatment (penicillin) from participants without disclosure
C.Enrolling participants from multiple countries without harmonized rules
D.Failing to publish the study results
Correct Answer: Withholding available effective treatment (penicillin) from participants without disclosure
Explanation:
In Tuskegee, effective penicillin therapy was deliberately withheld and the study's true nature concealed, causing preventable harm. This deception and denial of treatment drove reforms including the Belmont Report and informed consent requirements, not issues of publication, payment, or multinational rules.
Incorrect! Try again.
60A researcher holds equity in the company sponsoring the drug trial they lead. Beyond disclosure, which management strategy most robustly addresses this conflict of interest?
Issues in research ethics
Hard
A.Increasing the sample size to dilute bias
B.Selecting only participants likely to respond favorably
C.Simply noting the interest in the methods section
D.Divesting the financial interest or delegating trial oversight to an independent party
