Final answer:
When collecting blood for a coagulation profile, it is especially important to minimize vascular trauma during venipuncture.
Step-by-step explanation:
When collecting blood for a coagulation profile, it is especially important to minimize vascular trauma during venipuncture. This is because vascular trauma can lead to the activation of coagulation factors and affect the accuracy of the coagulation profile. The choice of anticoagulant is also important, but in this case, the correct answer is not B. Use of EDTA as the anticoagulant. EDTA is commonly used for hematological tests, not specifically for coagulation profiles. Analyzing the sample immediately is not a feasible option as coagulation testing requires specific equipment and procedures, and it is not possible to analyze the sample immediately after collection. The correct answer is A. Minimize vascular trauma during venipuncture.
