Total questions: 17
Worksheet time: 9mins
What is the primary function of sodium citrate in a blue top tube?
To act as a preservative
To serve as an anticoagulant
To enhance blood clotting
To provide nutrients to blood cells
Why is it important for the blue top tube to be filled to at least 90%?
To ensure the blood sample is not contaminated
To maintain the correct blood-to-additive ratio
To prevent the blood from clotting
To ensure the tube does not break
What could be a potential consequence of sending an underfilled blue top tube to the lab?
The blood sample will clot immediately
The test results may be falsely elevated
The tube will be rejected by the lab
The blood cells will die
Explain why a 9:1 blood-to-additive ratio is crucial for accurate test results in coagulation studies.
It ensures the blood sample is preserved for longer periods
It prevents the blood from clotting too quickly
It provides the most accurate test results
It allows for more tests to be conducted on the same sample
What is the role of sodium citrate in coagulation studies?
It accelerates the clotting process
It stabilizes the blood sample
It binds calcium ions to prevent clotting
It enhances the color of the blood sample
How might an underfilled blue top tube affect a patient's treatment plan?
It could lead to an incorrect diagnosis
It might cause the patient to be overmedicated
It would have no effect on the treatment plan
It could result in a delayed treatment
What tests are typically performed using a blue top tube?
Blood glucose levels
Coagulation studies
Complete blood count
Blood typing
Discuss the importance of using the correct blood-to-additive ratio in laboratory tests.
It ensures the sample is large enough for multiple tests
It prevents the sample from being rejected by the lab
It ensures the accuracy and reliability of test results
It allows for faster processing of the sample
What might happen if a blue top tube is overfilled?
The test results will be more accurate
The blood will clot inside the tube
The sodium citrate will be diluted
The tube will be rejected by the lab
What is the consequence of a falsely elevated test result due to an underfilled blue top tube?
The patient may receive an incorrect diagnosis
The test will need to be repeated
The patient may be prescribed an incorrect dosage of medication
The sample will be discarded
How does the incorrect filling of a blue top tube impact the reliability of coagulation studies?
It has no impact on the reliability
It can lead to inaccurate test results
It makes the test results more reliable
It speeds up the testing process
In order for blue top to get all the calcium, how many times must it be inverted to be properly mixed?
1 - 3
2 - 4
3 - 5
4 - 6
5 - 8
Once blue top is filled and mixed, it is taken to the laboratory chilled.
true
false
A discard tube is manadatory before drawing a blue top tube.
True
False
What are the exceptions for a discard tube before drawing a blue top tube? Choose all that apply.
It is always necessary
It is never necessary
If you're using a butterfly set coupled into a tube holder
They affect other factor assays like factor 8, factor 9 or other esoteric coagulation tests
After you have spun down a light blue top tube, what is the liquid part on top of your cells? plasma or serum?
plasma
serum
A blue top tube must be sent to the lab and tested within 4 hours of draw?
True
False
