Study Notes

Communicating CT Scan Results

Patients should be informed about the risks and benefits of CT scans based on their serum levels.
CT scans should be recommended for patients with serum levels above 2 standard deviations from the mean.

Serum Levels and Population Percentiles

Serum levels below 80 mg/dL are present in a certain percentage of the population.
A serum level of 110 mg/dL indicates the patient is above the mean.
2 standard deviations above the mean corresponds to a specific serum level.

Heel-Prick Tests

Heel-prick tests are done at birth to screen for certain conditions.
The tests are used to detect conditions such as phenylketonuria (PKU).
Documenting a mother's refusal of the heel-prick test is essential.

Physician-Patient Communication

Effective communication should be empathetic and avoid overly technical language.
Physicians should address patient concerns about radiation exposure.
Quitting smoking is not directly related to the patient's concern about CT scans.

Screening Guidelines

US Preventive Service Task Force guidelines influence a physician's recommendation for CT scans.
The guidelines do not recommend weekly CT scans for lung health monitoring.
Yearly x-rays are not an appropriate alternative to CT scans.

Research Concepts

The concept of ensuring results are not due to random chance is addressed in a specific topic.
The process of applying research findings to a general population is called external validity.
The Bradford-Hill criteria are used to establish causality in research.

Ethical Considerations

Enrolling children in research raises concerns about their protection.
Futile treatment addresses the issue of providing unnecessary treatment.
Balancing patient autonomy with beneficence is crucial in making medical decisions.
Managing patients who refuse vaccinations despite recommended guidelines involves an ethical consideration.
Confidentiality is essential in maintaining patient trust.
Biological plausibility is a key criterion in establishing causality according to the Bradford-Hill criteria.
