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 When performing venipuncture, the purpose of the tourniquet is to make the veins more visible and palpable, making it easier to locate a suitable vein for blood collection. However, the use of a tourniquet needs to be done carefully, especially in patients with certain conditions.<\/p>\n\n\n\n Explanation:<\/strong><\/p>\n\n\n\n In conclusion, the most appropriate action when assessing the use of a tourniquet is to avoid its use on patients with a history of bleeding, as it can lead to further complications.<\/p>\n\n\n\n Which action is correct when assessing the use of a tourniquet for venipuncture?A.

This is incorrect because applying a tourniquet too tightly, to the point where the distal pulse is no longer palpable, can cause unnecessary discomfort, tissue damage, or even thrombosis. The tourniquet should be tight enough to restrict venous blood flow but should still allow for the arterial pulse to be palpable.<\/li>\n\n\n\n
This is the correct answer. In patients with a history of bleeding disorders (such as hemophilia or those on anticoagulants), using a tourniquet can potentially lead to complications like excessive bruising or hematomas. The pressure exerted by the tourniquet can exacerbate bleeding, and alternative methods for venipuncture should be considered.<\/li>\n\n\n\n
This is incorrect because the tourniquet should only be applied for a short period (usually around 1 minute or less). Prolonged application of the tourniquet can cause discomfort and increased difficulty in performing the procedure, and it may lead to hemoconcentration, which can affect the test results.<\/li>\n\n\n\n
This is an acceptable alternative in some cases. Using a blood pressure cuff inflated to around 60 mm Hg can create a similar effect as a tourniquet, but it should not be relied upon as a routine method. It can be useful for patients with difficult veins or those who have had adverse reactions to the regular tourniquet.<\/li>\n<\/ol>\n\n\n\n<\/ol>\n","protected":false},"excerpt":{"rendered":"
