Final answer:
The rooting reflex can be tested by gently stroking the baby's cheek or the corner of their mouth. A pathological response refers to an abnormal or exaggerated reaction to the rooting reflex.
Step-by-step explanation:
The rooting reflex can be tested by gently stroking the baby's cheek or the corner of their mouth. In response to the stimulus, the baby will turn their head in that direction and open their mouth, as if searching for the source of the touch. This reflex is present in newborn infants and helps them find the nipple for feeding.
A pathological response refers to an abnormal or exaggerated reaction to the rooting reflex. For example, if the baby's head does not turn in the direction of the stimulus or if they have difficulty finding the nipple, it may indicate a neurological or developmental issue that requires further evaluation and intervention.
