**Core Concept**
Inhaled foreign bodies in infants can lead to significant airway obstruction and potential respiratory compromise. Prompt and effective management is crucial to prevent serious complications.

**Why the Correct Answer is Right**
The best management for inhaled foreign bodies in infants involves the Heimlich maneuver, also known as back blows. This technique involves a series of sharp blows between the shoulder blades to dislodge the foreign object from the airway. The mechanism behind this is the creation of negative pressure in the thoracic cavity, which helps to dislodge the object and restore normal airflow. The American Academy of Pediatrics recommends the Heimlich maneuver as the first line of treatment for inhaled foreign bodies in infants.

**Why Each Wrong Option is Incorrect**
**Option A:** This option is likely a distractor, as there is no widely recognized treatment for inhaled foreign bodies in infants involving "abdominal thrusts only." While abdominal thrusts are a component of the Heimlich maneuver, they are not sufficient on their own to manage inhaled foreign bodies.
**Option B:** This option is incorrect because "nasopharyngeal airway (NPA) insertion" is not a recommended treatment for inhaled foreign bodies. NPAs are used to manage airway obstruction due to other causes, such as trauma or edema.
**Option C:** This option is incorrect because "surgical intervention" is not typically the first line of treatment for inhaled foreign bodies. While surgery may be necessary in some cases, it is usually reserved for situations where other treatments have failed or the object is too large to be removed via other means.

**Clinical Pearl / High-Yield Fact**
It's essential to remember that the Heimlich maneuver should be performed with the infant in an upright position, with the head lower than the chest, to facilitate the removal of the foreign object.

**Correct Answer:** C.
