Final answer:
A patient should make a strong fist when blood is being drawn to help the veins become more prominent, aiding in the venipuncture process. The healthcare provider must use sterile equipment, clean the site to prevent infection and communicate clearly with the patient.
Step-by-step explanation:
When drawing blood, it is essential to have the patient make a strong fist. This procedure aids in the venipuncture process by making the veins more prominent and easier to puncture. However, caution should be taken to ensure that the patient does not pump the hand, as this may cause hemoconcentration, affecting the test results. The approach to blood drawing takes skilled technique and knowledge of anatomy, as well as adherence to safety protocols to prevent injury to the patient or healthcare provider.
Prior to the blood draw, it is recommended to have the patient seated or lying down to reduce the risk of fainting. Additionally, the healthcare provider must ensure that all equipment is sterile, and that the site of the venipuncture is thoroughly cleaned to prevent infection. Throughout the procedure, maintaining clear communication with the patient is important to alleviate any fear or anxiety and to provide instructions as needed.
