Final answer:
The most effective method for administering ventilations to an apneic patient is Bag-valve-mask ventilation, as it allows for high oxygen concentration and proper ventilation rates. The correct option is B) Bag-valve-mask ventilation.
Step-by-step explanation:
The most effective method for administering ventilations to an apneic patient is B) Bag-valve-mask ventilation. This technique allows a rescuer to provide high concentrations of oxygen to the patient while also enabling the possibility of delivering ventilations at an adequate rate and volume.
It is typically preferred over mouth-to-mouth ventilation because it can deliver a higher oxygen concentration and helps prevent the transmission of infectious diseases. Chest compressions are a crucial part of cardiopulmonary resuscitation (CPR) but are not a direct method of ventilation.
Abdominal thrusts are used to clear a blocked airway, typically in the case of choking, and are not used for ventilating an apneic patient.
This method involves using a bag-valve-mask device to deliver breaths to the patient. It provides more effective ventilations compared to mouth-to-mouth ventilation (option C) because it allows for a higher concentration of oxygen to be delivered and can generate higher pressures.
Chest compressions (option A) and abdominal thrusts (option D) are not methods used for administering ventilations, but are techniques used in CPR and choking emergencies, respectively.
The correct option is B) Bag-valve-mask ventilation.
