Answer :
Final answer:
Capillary punctures utilize a lancet to puncture the skin and a Microtainer to collect blood. The lancet is essential for creating the initial cut, and the Microtainer efficiently gathers the resulting blood sample. Other options regarding storage or holding functions are not applicable.
Explanation:
Understanding Capillary Punctures
Capillary punctures are common procedures for obtaining blood samples, often used when only a small amount of blood is necessary. The devices and containers involved in this process include the lancet and the Microtainer.
Functions of Devices and Containers
- The lancet punctures the capillary. This is the primary function of the lancet, a small, sharp instrument that creates a small incision in the skin, typically on a fingertip, allowing blood to flow out.
- The Microtainer collects the blood. Once the skin is punctured, the Microtainer is used to collect the blood sample. It is specifically designed to draw in small volumes of blood through capillary action.
Other options listed, such as the lancet storing blood or the Microtainer holding the capillary tube, are incorrect. The capillary tube itself does not pinch a hole in the skin; this is done by the lancet. Therefore, only the two selected options apply to the role of devices and containers used in capillary punctures.
