In 1951, Henrietta Lacks, an African American woman, sought treatment at Johns Hopkins Hospital for severe abdominal pain. During her examination, doctors discovered a malignant tumor on her cervix. Without her knowledge or consent, cells from her tumor were collected by Dr. George Gey, a prominent cancer researcher.
Remarkably, while most cells died shortly after being removed from the body, Lacks’s cells thrived and multiplied indefinitely in the lab. These “immortal” cells, named HeLa cells, became a cornerstone of medical research. They have been instrumental in numerous scientific breakthroughs, including the development of the polio vaccine, advancements in cancer treatments, and insights into virology.
Despite the monumental impact of her cells, Henrietta Lacks remained anonymous for decades, and her family was unaware of her contribution to science. This case raises important ethical questions about informed consent and patients’ rights in medical research.
NCLEX-Style Question: Ethical Considerations:
A nurse is reviewing ethical principles in medical research with a group of nursing students. Which of the following scenarios presents the greatest ethical concern regarding informed consent?
A) A patient signs a consent form for an experimental drug trial but later withdraws consent. The physician encourages them to continue participation, stating their data is already being used in research.
B) A researcher collects excess tissue samples removed during surgery and uses them for genetic studies after obtaining broad consent from the patient.
C) A physician submits a case report detailing a unique disease presentation using de-identified patient information without seeking additional consent.
D) A patient donates blood for routine testing, and the hospital later uses the de-identified sample for research on an emerging infectious disease.
Answer: A
Rationale:
While all options present ethical concerns, option A is the most problematic because it involves coercion, a direct violation of the patient’s autonomy. Patients have the right to withdraw consent at any time in research studies, and continuing to use their data after withdrawal without their explicit agreement compromises ethical standards.
- Option B is ethically acceptable if broad consent is obtained, as patients sometimes agree to future research use of samples.
- Option C may be questionable but does not breach confidentiality since the data is de-identified.
- Option D aligns with some hospital policies, under which de-identified specimens can be used for public health research, provided they comply with institutional guidelines.
