A medical assistant needs to draw a blood glucose level on a patient.. Which of the following tubes should they use? D Lavender top tube Red top tube Light blue top tube Gray top tube

## Step 1<br />The problem is asking us to identify the correct type of tube a medical assistant should use when drawing a blood glucose level from a patient. The options provided are: D Lavender top tube, Red top tube, Light blue top tube, and Gray top tube.<br /><br />## Step 2<br />The correct answer is the Light blue top tube. This is because the Light blue top tube contains sodium citrate, which is an anticoagulant. This means it prevents the blood from clotting, which is necessary for accurate blood glucose testing.<br /><br />## Step 3<br />The other options, such as the Lavender top tube, Red top tube, and Gray top tube, are not suitable for this purpose. The Lavender top tube contains EDTA, an anticoagulant that can interfere with the accuracy of the blood glucose test. The Red top tube does not contain any anticoagulant, which can also affect the accuracy of the test. The Gray top tube contains potassium oxalate and sodium fluoride, which can also interfere with the accuracy of the test.
