The standard of care used in phlebotomy malpractice cases is often based on guidelines from what organization?

Answer: CLSI - Clinical and Laboratory Standards Institute

The standard of care used in phlebotomy malpractice cases is often based on guidelines from CLSI (Clinical and Laboratory Standards Institute). This organization provides standards and guidelines for laboratory testing and procedures, including phlebotomy practices. These guidelines are widely accepted in the healthcare industry and serve as a reference for establishing the expected level of care in phlebotomy procedures.

What is the recommended disinfectant for blood culture sites in infants 2 months and older?

Answer: Chlorhexidine gluconate

The recommended disinfectant for blood culture sites in infants 2 months and older is chlorhexidine gluconate. Chlorhexidine gluconate is an antiseptic agent that is effective against a wide range of microorganisms and is commonly used to disinfect the skin prior to invasive procedures such as blood culture collection. It has been shown to reduce the risk of contamination and infection during blood draws.

The composition of capillary puncture blood more closely resembles what?

Answer: Arterial Blood

The composition of capillary puncture blood more closely resembles arterial blood. Capillary blood, obtained from a fingerstick or heel stick, is oxygenated and has a similar composition to arterial blood because it is sourced from the capillaries, which are part of the arterial system. Capillary blood is typically used for point-of-care testing and provides a more immediate representation of blood gas and metabolic status compared to venous blood.

What is the purpose of an antiglycolytic agent?

Answer: Preserve glucose

The purpose of an antiglycolytic agent in blood collection is to preserve glucose levels in the blood sample. Antiglycolytic agents such as sodium fluoride are added to blood collection tubes to prevent the metabolism of glucose by blood cells during storage. By inhibiting glycolysis, these agents help maintain accurate glucose levels for laboratory analysis.

A phlebotomist arrives to collect a 2-hour post-prandial glucose specimen on an inpatient and discovers that 2 hours have not elapsed since the patient's meal. What should the phlebotomist do?

Answer: Ask the patient's nurse to verify the correct time to draw the specimen.

This ensures that the specimen is collected at the appropriate time according to the specific testing requirements.

Which type of specimen is typically used for routine urinalysis?

Answer: Random

The type of specimen typically used for routine urinalysis is a random urine sample. This sample can be collected at any time of day and does not require specific timing or preparation. It provides general information about the patient's kidney function, hydration status, and potential presence of abnormal substances such as glucose or proteins in the urine.

The manufacturer must supply an SDS for which one?

Answer: Isopropyl and methyl alcohol.

The manufacturer must supply a Safety Data Sheet (SDS) for isopropyl and methyl alcohol. SDS provides essential information about the properties and potential hazards of chemical substances or mixtures. Isopropyl alcohol and methyl alcohol (methanol) are chemicals commonly used in various applications, including disinfection and cleaning.For other items like fluid-resistant laboratory coats, certain prescribed medications, or isotonic sodium chloride solution, SDS may not be required or applicable. However, it's essential to refer to safety guidelines and manufacturer's instructions for proper handling and use of these items.

Which of the following micro collection containers should be filled first if collected by capillary puncture?

Answer: Lavender top

When collecting specimens by capillary puncture, it's important to prioritize the order of draw to avoid cross-contamination and ensure accurate results. The lavender-top micro collection container is typically used for hematology tests, such as complete blood count (CBC), and should be filled first in the order of draw. This helps prevent contamination from other additives present in tubes with different colored tops.

A quadriplegic patient can do what of the following?

Answer: Can feel pain if there is no sensory damage.

Quadriplegia impacts both motor and sensory functions in the affected areas of the body, but the degree and specific manifestations can vary widely based on the underlying cause and extent of injury.

Biological Substance Category B regulations must be followed when shipping laboratory specimens for diagnostic purposes by public transportation. These regulations require the specimens to be what?

Answer: Triple packaged in a watertight primary container.

This packaging typically includes placing the specimen in a leak-proof primary container, which is then enclosed in a secondary leak-proof container (such as a specimen bag or box), followed by additional outer packaging for protection during transport. The triple packaging helps ensure the safe transport of potentially infectious materials while complying with transportation regulations.

What is CLIA?

Answer: Clinical Laboratory Improvement Amendments

CLIA stands for Clinical Laboratory Improvement Amendments. It is a set of regulations established by the United States federal government to ensure quality laboratory testing. The CLIA program ensures that clinical laboratory testing is accurate, reliable, and timely by setting standards for laboratory personnel qualifications, quality control procedures, proficiency testing, and more. Laboratories that perform testing on human specimens for health assessment or the diagnosis, prevention, or treatment of disease are subject to CLIA regulations to ensure the accuracy and reliability of their testing processes.
