Which of the following actions should a medical assistant take when performing a capillary puncture on a 10-month-old patient?

While applying a bandage may be necessary after the procedure to protect the site, it does not address the immediate needs of preparing for a successful capillary puncture. Holding pressure is typically done after the puncture to stop any bleeding, but this step does not enhance blood flow prior to the procedure.

This choice seems incomplete but suggests applying direct pressure, which is appropriate after a puncture to control bleeding. However, it does not pertain to the preparatory steps necessary for successfully obtaining a sample, such as warming the site.

Applying firm pressure is crucial post-puncture to prevent excessive bleeding, but this action does not facilitate or prepare the site for the procedure itself. Thus, it does not contribute to improving the success rate of the capillary puncture.

While having a parent hold the child can provide comfort and stability during the procedure, it does not enhance the physical preparation of the puncture site. The focus should be on techniques that improve blood flow to ensure a successful sample collection.
