The patient has no complaints, and she does not have any past medical problems. She takes no medications. The patient reports that she remains active, exercising 5 times a week, and eats a healthy and varied diet. Which of the following would be the best way for the physician to obtain a more in-depth social history, including sexual history and use of alcohol, tobacco, or recreational drugs?

Ask the mother to step outside into the hall for a portion of the visit

A 28-year-old woman dies shortly after receiving a blood transfusion. Autopsy reveals widespread intravascular hemolysis and acute renal failure. Investigation reveals that she received type A blood, but her medical record indicates she was type O. In a malpractice lawsuit, which of the following elements must be proven?

Duty, breach, causation, and damages

A 3-year-old is brought to the pediatrician by his mother because she is concerned about recent changes to his behavior. She states that he has seemed to regress in his motor development and has been having occasional brief episodes of uncontrollable shaking. During the subsequent work up, a muscle biopsy is obtained which demonstrates red ragged fibers and a presumptive diagnosis of a genetic disease made. The mother asks if her other son will be affected. What should be the physician's response?

There is a 100% chance he will be affected, but the severity may be different

There is a 50% chance he will be affected

There is a 100% chance he will be affected, and the severity will be the same

There is a 25% chance he will be affected

A 26-year-old man comes to the emergency department because of a 1-week history of fever, throat pain, and difficulty swallowing. Head and neck examination shows an erythematous pharynx with purulent exudates overlying the palatine tonsils. Microscopic examination of a throat culture shows pink, spherical bacteria arranged in chains. Treatment with amoxicillin is initiated. A day later, a physician colleague from another department approaches the physician in the lobby of the hospital and asks about this patient, saying, "Did you see him? What does he have? He's someone I play football with and he hasn't come to play for the past 5 days. I'm worried about him." Which of the following is the most appropriate action by the physician?

Inform the colleague that they cannot divulge any information about the patient

Inform the colleague that they should ask the patient's attending physician

Tell the colleague the patient's case file number so they can look it up themselves

Tell the colleague that they cannot tell them the diagnosis but that their friend was treated with antibiotics

Ask the colleague to meet in the office so they can discuss the patient in private

A 34-year-old man presents to the local clinic with a 2 month history of midsternal chest pain following meals. He has a past medical history of hypertension. The patient takes lisinopril daily. He drinks 4–5 cans of 12 ounce beer daily, and chews 2 tins of smokeless tobacco every day. The vital signs are currently stable. Physical examination shows a patient who is alert and oriented to person, place, and time. Palpation of the epigastric region elicits mild tenderness. Percussion is normoresonant in all 4 quadrants. Murphy’s sign is negative. Electrocardiogram shows sinus rhythm with no acute ST segment or T wave changes. The physician decides to initiate a trial of omeprazole to treat the patient’s gastroesophageal reflux disease. How can the physician most effectively assure that this patient will adhere to the medication regimen?

Have the patient repeat back to the physician the name of the medication, dosage, and frequency

Instruct the patient to purchase a weekly pill organizer

Provide the patient with details of the medication on a print-out

Contact the pharmacist because they can explain the details more thoroughly

Tell the patient to write the medication name, dosage, and frequency on their calendar at home

Ethics of emerging technologies for USMLE Step 3: High-Yield Patient Safety Lessons

Genomic Medicine - Editing Our Code

Core Technology: CRISPR-Cas9 enables precise DNA modification to correct pathogenic mutations.
Key Ethical Distinction:
- Somatic Editing: Affects only the individual (non-heritable). Ethically viewed similarly to advanced medical treatments.
- Germline Editing: Alters sperm, eggs, or embryos. Changes are permanent and heritable, impacting future generations.
Primary Ethical Issues:
- Safety: Risk of off-target mutations and unforeseen long-term health consequences.
- Consent: Inability to obtain consent from future generations for germline changes.
- Justice: Concerns over equitable access and creating a genetic class divide ("designer babies").

⭐ High-Yield Point: The fundamental ethical boundary in gene editing is between somatic (non-heritable, therapeutic) and germline (heritable) modifications. US regulations currently restrict federal funding for research involving heritable human germline editing.

AI & Robotics - Rise of Robot Docs

da Vinci Robotic Surgery OR Setup and Robotic Arm

AI in Medicine: Double-Edged Sword
- Benefits: ↑Precision in diagnostics (radiology), analyzing massive datasets, potential to ↓human error.
- Risks: Algorithmic bias from non-diverse training data, patient data privacy (HIPAA), "black box" decision-making, physician deskilling.
Robotic Surgery (e.g., Da Vinci)
- Pros: Enhanced dexterity, tremor filtration, minimally invasive approaches.
- Cons: High cost, loss of haptic feedback, steep learning curve, rare but critical mechanical failures.
Core Ethical & Legal Challenges
- Accountability: Who is liable for an AI-driven error? The clinician, hospital, or developer?
- Informed Consent: How to adequately explain AI's role and risks to patients.
- Justice: Ensuring equitable access and avoiding a two-tiered system of care.

⭐ The FDA regulates many AI systems as Software as a Medical Device (SaMD). A primary concern is that biased training data can cause AI to perpetuate or even amplify existing health disparities in minority populations.

Telehealth & Big Data - The Virtual Patient

Telehealth: Remote healthcare delivery via telecommunication.
- Benefits: ↑ Access to care, patient convenience, potential cost savings.
- Ethical/Legal Hurdles:
  - Privacy/Security: Platforms must be HIPAA-compliant to protect against data breaches.
  - Digital Divide: Can worsen health disparities for patients lacking tech access/literacy.
  - Licensure: Physicians must be licensed in the state where the patient is located.
Big Data/AI in Medicine: Analyzing large health datasets to predict outcomes.
- Challenges:
  - Algorithmic Bias: Models trained on non-representative data can perpetuate inequities.
  - Accountability: Determining liability for AI-driven medical errors.

⭐ High-Yield: A major telehealth challenge is maintaining the standard of care, ensuring it is equivalent to an in-person consultation, particularly for making a new diagnosis.

Reproductive Technologies - Designer Baby Dilemmas

Preimplantation Genetic Diagnosis (PGD): Screening embryos for monogenic diseases (e.g., Cystic Fibrosis, Huntington's) or chromosomal abnormalities before implantation.
**Ethical Pros (Proponents' View):
- Beneficence: Prevents suffering from severe genetic disorders.
- Autonomy: Respects parental rights to make reproductive choices.
**Ethical Cons (Opponents' View):
- Non-Maleficence: Potential for unforeseen long-term health risks from manipulation.
- Justice: High cost may lead to genetic inequity, creating a "genetically privileged" class.
- "Slippery Slope": Transitioning from disease prevention to non-medical trait enhancement (e.g., intelligence, appearance).

⭐ The core ethical conflict lies in distinguishing between therapy (acceptable use to prevent disease) and enhancement (controversial use to select for desired traits), which raises fears of modern eugenics.

Preimplantation Genetic Diagnosis (PGD) Process

High‑Yield Points - ⚡ Biggest Takeaways

Telemedicine requires strict HIPAA compliance for data security and physicians must be licensed in the patient's state.

AI algorithms carry risks of inherent bias, "black box" opacity, and unclear accountability for errors.

EHRs can compromise patient privacy and propagate errors through careless use of features like copy-paste.

Genomic medicine requires clear informed consent regarding incidental findings and protection from genetic discrimination (GINA).

Determining liability for errors in robotic surgery or with AI-assisted diagnosis is a major ethical and legal challenge.
