Final answer:
The preferred method for initially providing artificial ventilations to a patient with apnea is the One-person bag-valve-mask technique with 100% oxygen.
Step-by-step explanation:
The preferred method for initially providing artificial ventilations to a patient with apnea is the One-person bag-valve-mask technique with 100% oxygen (option C). This technique involves using a bag-valve-mask device, which consists of a mask that covers the patient's nose and mouth connected to a bag that is manually squeezed to ventilate the patient's lungs. The use of 100% oxygen helps to improve oxygenation.
