When collecting a blood sample from an elderly, frail patient, what is the best collection device to use?

1. Butterfly needle

2. Vacutainer

3. A syringe

4. Capillary tube

The correct answer is: A syringe

Using a syringe is often recommended for collecting blood samples from elderly or frail patients. This is primarily due to the ability of a syringe to provide better control during the collection process. When dealing with fragile veins, especially in elderly patients where the veins may be thinner or more prone to collapse, a syringe allows the phlebotomist to apply a gentle and consistent suction. This method reduces the risk of vein damage and ensures that the blood is collected more safely and efficiently. Utilizing a syringe also enables the healthcare provider to draw blood without creating undue tension on the vein. This is particularly important in frail individuals who may experience discomfort or stress from traditional blood collection methods. While the other options can be effective in different scenarios, they may not provide the same level of control as a syringe. The butterfly needle, for instance, is often used for smaller veins but may still pose a risk if not handled carefully. A Vacutainer is typically more advantageous for patients with larger, more prominent veins. Capillary tubes are typically used for smaller blood sample sizes and may not be suitable for a complete blood draw necessary from a frail patient. Thus, the use of a syringe stands out as the most appropriate choice for this specific population.
