Veterinary Technician Practice Exam

In the context of animal restraint for venipuncture, what is a critical action to take when the practitioner signals readiness?

1. Check for any signs of distress in the animal

2. Lift occluding pressure from the vein

3. Stabilize the animal’s head

4. Prepare for immediate withdrawal of the needle

The correct answer is: Lift occluding pressure from the vein

When the practitioner signals readiness during venipuncture, it is essential to lift occluding pressure from the vein. This action allows for blood flow into the needle once it is inserted, ensuring that the collection process can occur effectively. Lifting the occluding pressure can help to avoid damage to the vein and ensure an adequate blood sample is obtained without excessive trauma to the blood vessel or surrounding tissues. Maintaining proper blood flow is crucial, as it affects the quality of the sample and reduces the risk of complications such as hematomas or excessive bleeding. This step must occur promptly once the practitioner indicates readiness to proceed with the venipuncture, maximizing efficiency and minimizing discomfort for the animal. While it is also important to check for signs of distress in the animal, stabilize the head, and be prepared for immediate withdrawal of the needle, these actions are secondary to ensuring the vascular access is optimal by lifting the occluded pressure. Each of these other tasks plays a role in the overall process, but the primary focus at the moment of readiness is to facilitate the successful collection of the blood sample.
