Which action is correct when assessing the use of a tourniquet for venipuncture?
A. Apply the tourniquet tight enough that the patient’s distal pulse can no longer be palpated.
B. Do not use a tourniquet on a patient with a history of bleeding.
C. Apply the tourniquet for at least 2 minutes for best results.
D. Substitute a blood pressure cuff inflated to 60 mm Hg for the tourniquet.<\/p>\n\n\n\n
The correct answer and explanation is:<\/mark><\/strong><\/p>\n\n\n\n The correct answer is B. Do not use a tourniquet on a patient with a history of bleeding<\/strong>.<\/p>\n\n\n\n Explanation: Option A<\/strong> is incorrect because applying the tourniquet too tightly to the point where the distal pulse is no longer palpable can be dangerous. It can cause pain and increase the risk of vascular injury or thrombosis. It is essential to apply the tourniquet snugly but not so tightly that it cuts off circulation completely.<\/p>\n\n\n\n Option C<\/strong> is also incorrect. Applying a tourniquet for more than 1 minute is generally discouraged. Prolonged use can cause discomfort, increase the risk of hemoconcentration, and potentially affect the quality of the sample. Ideally, the tourniquet should be applied for 1 minute or less, just enough to make the veins visible and palpable.<\/p>\n\n\n\n Option D<\/strong> is partially correct in the context that a blood pressure cuff can sometimes be used as an alternative to a tourniquet, but it should not be inflated to 60 mm Hg. The cuff should only be inflated to a level that helps engorge the veins without causing undue pressure or discomfort. Additionally, it is not a complete substitute for a tourniquet in every situation and should be used with caution.<\/p>\n\n\n\n In summary, when performing venipuncture, it is essential to ensure the tourniquet is applied appropriately, and special care should be taken with patients who have bleeding disorders to avoid any further complications.<\/p>\n","protected":false},"excerpt":{"rendered":" Which action is correct when assessing the use of a tourniquet for venipuncture?A.

The use of a tourniquet during venipuncture is a common practice, as it helps to engorge the veins and make them easier to locate. However, its use should be carefully considered based on the patient\u2019s medical history. In patients with a history of bleeding disorders, applying a tourniquet could exacerbate the situation, potentially leading to excessive bleeding or complications such as hematomas.<\/p>\n\n\n\n
