Final answer:
The cricoid pressure maneuver in infants involves applying pressure on the cricoid cartilage.
Step-by-step explanation:
The correct answer is d. Pressure on the cricoid cartilage.
In infants, the cricoid pressure maneuver is performed by using one fingertip and applying pressure on the cricoid cartilage, which is located in the neck. This maneuver is used to prevent aspiration during endotracheal intubation.
Applying pressure on the sternum, neck, or abdomen is not the recommended technique for the cricoid pressure maneuver in infants.
