How long should a tube be pre-warmed in an incubator before collecting a warmed sample, such as Cold Agglutinins?
It is necessary to keep warmed specimens heated until the serum is separated from the cells. Collecting in tubes that have been pre-warmed in an incubator or a chemical hand warmer for 30 minutes will achieve this.
What size venipuncture needle has the smallest gauge?
Typically, venipuncture is performed with needles with a gauge of 20 to 23. The likelihood of hemolyzing the specimen increases when using a gauge lower than 23.
Which needle gauge size has the largest bore (opening) among the rest?
Smaller bores are correlated with higher gauge sizes (openings). Given this, the 18 G needle would have the largest needle aperture and the 25 G needle would have the smallest needle opening.
What organ of the human body has the tiniest veins?
Venules, the tiniest veins in the body, receive blood from the arteries through the arterioles and capillaries. The blood finally travels through the venules and bigger veins to the vena cava, the largest vein in the body.
Which of the following best describes a management function that involves exercising quality control over raw materials, assemblies, produced materials and components, production-related services, management, production, and inspection processes with the aim of preventing covert production of defective goods or provision of subpar services?
The term "quality control" refers to the overall management process whereby the management, production, and inspection processes are exercised to control the quality of raw materials, assemblies, produced materials and components, services related to production, and management, production, and inspection processes with the aim of preventing covert production of defective goods or provision of subpar services. Patient information handling needs are addressed by HIPAA compliance. Standards of patient care are related to quality of care. A group of operational procedures to guarantee the achievement of an outcome would be referred to as best practices.
Which test from the list below doesn't require fasting?
A 9–12 hour fast is often necessary for a lipid profile test. Iron tests typically require a 12-hour fast, while a renal function panel calls for an 8–12-hour fast. There is no need to fast before a full blood count test.
What should be done if a patient reports having previously fainted during venipuncture?
When a patient says they experience dizziness while having blood drawn, you should take all necessary precautions to guarantee their safety. Having them lie down before you start the collecting is the easiest way to accomplish this.
