Submit
21. Which of these elements in blood is bound by EDTA in a collection tube to prevent clotting?

Explanation

EDTA (ethylene diamine tetraacetic acid) is a chelating agent commonly used in blood collection tubes to prevent clotting. It works by binding to calcium ions in the blood, which are essential for the coagulation cascade. By removing calcium, EDTA inhibits the formation of blood clots, allowing the blood sample to remain in a liquid state for further analysis. Therefore, calcium is the element in blood that is bound by EDTA in a collection tube to prevent clotting.

Submit
22. Squeezing the finger too vigorously during the capillary bloood collection can cause erroneous lab results due to

Explanation

Squeezing the finger too vigorously during capillary blood collection can cause erroneous lab results due to dilution with tissue fluid. When the finger is squeezed too hard, it can cause the tissue fluid to mix with the blood sample, leading to inaccurate results. This dilution can affect the concentration of various components in the blood, such as electrolytes or blood cells, which can result in false readings. It is important to collect capillary blood samples gently to avoid this dilution and obtain accurate laboratory results.

Submit
23. The smallest veins of the human anatomy are known as_____

Explanation

Venules are the correct answer because they are the smallest veins in the human anatomy. Venules collect blood from capillaries and carry it back to the larger veins. Arteries carry oxygenated blood away from the heart, while arterioles are small branches of arteries. Capillaries are tiny blood vessels that connect arteries and veins, allowing for the exchange of oxygen, nutrients, and waste products.

Submit
24. Why does a multi sample needle have a rubber sleeve over the end of the needle that is inserted into the collection tube?

Explanation

The rubber sleeve on the end of the multi sample needle prevents blood from seeping into the adapter. This is important because if blood were to enter the adapter, it could contaminate the collection tubes and potentially affect the accuracy of the test results. By having the rubber sleeve, it creates a barrier that prevents any blood from seeping into the adapter, ensuring the integrity of the samples collected.

Submit
25. To draw blood from  apatient with an open IV line the selected site should be located _____

Explanation

When drawing blood from a patient with an open IV line, the selected site should be located above the IV. This is because drawing blood below the IV can cause the blood to flow back into the IV tubing, contaminating it. Drawing blood in the antecubital fossa (inner elbow) is a common site for venipuncture, but in this specific scenario, it is important to choose a site that is above the IV to prevent contamination.

Submit
26. One bedside (point of care) laboratory test that is used before surgery to check whether a patient has a sufficient number of working platelets is known as the ___ test.

Explanation

The partial thromboplastin time (PTT) test is used to assess the clotting ability of the blood. It measures the time it takes for blood to clot and is used to evaluate the functioning of certain clotting factors in the blood. Before surgery, it is important to ensure that a patient has a sufficient number of working platelets to prevent excessive bleeding during the procedure. Therefore, the PTT test is used to check the clotting ability and determine if the patient has enough platelets for surgery.
