Question 1

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

Accepted Answer

CLSI - Clinical and Laboratory Standards Institute

Answer

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.

Question 2

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

Accepted Answer

Chlorhexidine gluconate

Answer

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.

Question 3

The composition of capillary puncture blood more closely resembles what?

Accepted Answer

Arterial Blood

Answer

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.

Question 4

What is the purpose of an antiglycolytic agent?

Accepted Answer

Preserve glucose

Answer

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.

Question 5

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?

Accepted Answer

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

Answer

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