Study Notes

Blood Collection Techniques

Familiarity with blood collection tube additives is crucial; top colors indicate specific additives.
Sequence of tube draw is essential to prevent contamination and ensure accurate results.
Correct needle insertion and withdrawal techniques minimize patient discomfort and ensure effective blood sampling.
Special considerations are necessary for patients with varying age groups and medical conditions when performing venipuncture.
Incident recognition during blood collection is key; being prepared allows for appropriate responses.

Post-Collection and Other Specimen Handling

Proper aftercare for venipuncture involves correct bandaging and monitoring for complications.
Capillary punctures require specific techniques to avoid complications and ensure good blood flow.
Various urine specimen collection methods include random, clean catch, timed, and drug screening.
Procedures for collecting samples from pediatric patients require gentler techniques and clear instructions to assure comfort.

Specimen Management

Accurate labeling of specimens is crucial for tracking and preventing mix-ups.
Documenting specimen collection includes details like date, time, and procedures followed.
Performing quality control before testing ensures the reliability of results.

Point-of-Care Testing

CLIA-waived point-of-care tests include hematology (e.g., hemoglobin), chemistry (e.g., blood glucose), and immunology (e.g., quick-flu tests).
Chain-of-custody testing is vital for legal specimens, particularly in employment drug screening.

Patient Rights and Patient Care Partnership

Patients have the right to non-discriminatory treatment and to be informed about their care providers.
Informed consent is essential, covering risks, benefits, and the option for a do-not-resuscitate order.
Patients should have access to their medical records and the ability to voice complaints without fear of reprisal.

Safety and Infection Control

Wearing masks reduces infection transmission when interacting with patients.
The Hazard Communication Standard mandates a comprehensive hazard awareness program for all staff.
Key components include labeling hazardous chemicals, maintaining safety data sheets, and ensuring employee training.

Medical Assistance Guidelines

Medical assistants should avoid providing unsolicited medical advice to patients.
Focus on comfort and clarification of medical instructions from doctors or nurses instead of offering personal opinion.

Aseptic Techniques

Hand hygiene is the primary method for preventing infection; differing methods include soap washing and using alcohol-based rubs.
Specific hygiene practices are necessary before and after patient contact, particularly concerning visible soil or body fluids.

Special Considerations in ECG Testing

Adjustments for elderly patients and those with cognitive impairments include gentle handling and clear communication.
Special techniques apply for patients with missing limbs or physical disabilities when placing ECG leads.
Patient comfort and understanding are emphasized throughout the process, with procedures explained clearly.

Troubleshooting in ECG and Testing Procedures

Awareness of common artifacts and recording errors during ECG testing is essential for accurate readings and troubleshooting.
