Which pair of maneuvers is recommended for emergency care of a choking 5-month-old infant?

The correct answer involves performing a back blow followed by chest thrusts when addressing choking in a 5-month-old infant. This method is specifically recommended because it is designed to help alleviate obstructions in the airway of infants who may be choking.

Back blows are effective as they utilize the force of gravity and provide a quick, gentle yet impactful way to dislodge an object from the infant's airway. Administering firm back blows while holding the infant in a prone position can help create the necessary pressure to expel the object causing the blockage.

Following the back blows with chest thrusts is essential because it further increases the chances of clearing the airway obstruction. Chest thrusts mimic the technique of performing compressions but are specifically tailored to the needs of an infant—delivered in a way that is both safe and effective for their smaller bodies.

In contrast, other options such as the Heimlich maneuver are not recommended for infants under one year of age, as this technique can be too forceful and potentially cause injury. Similarly, performing a blind finger sweep can pose a risk of pushing the object further down the throat, which can worsen the situation. Thus, the combination of back blows and chest thrusts is the most appropriate and effective approach for treating choking
