Final answer:
To remove air bubbles from a syringe, point the needle upward and slowly push the plunger to expel the bubbles.
Step-by-step explanation:
The student's question pertains to the correct protocol for removing air bubbles from a syringe barrel before administering an injection. To achieve this, one must point the needle upward to allow any air bubbles in the barrel to rise to the top. Then, they should slowly push the plunger to expel the bubbles from the syringe. This process ensures that no air is injected into the patient's body, which can be critical in preventing air embolism, a potentially serious medical condition.
