Question 1

What is the maximum recommended tourniquet application time before specimen collection?

Accepted Answer

1 minute

The tourniquet should not remain in place for more than 1 minute before blood draw to avoid hemoconcentration and altered test results.

Question 2

Which of the following is a sign that a vacuum tube has expired and should not be used?

Accepted Answer

The tube fills slowly or not at all due to loss of vacuum

Answer

An expired vacuum tube loses its negative pressure, causing it to fill slowly or not at all, making it unsuitable for collection.

Question 3

When performing a capillary puncture on an adult fingertip, which area should be avoided?

Accepted Answer

The very tip of the finger and the areas with calluses

Answer

The very tip and calloused areas of the finger are avoided because they have poor blood flow and may cause inadequate specimen collection.

Accepted Answer

The safety shield or retractable needle mechanism

Answer

Safety-engineered needle devices include shields or retractable mechanisms that cover the needle immediately after withdrawal to prevent needlestick injuries.
