The infant in this picture is turning her head to the side to nurse which is more than likely pulling at the mothers breast and results in a shallow latch. Turning her infants body towards the breast would allow for a deeper latch and less strain.
In the case of sore nipples, both on the exam and in practice, look first to correcting positioning and latch before checking for the pathology, making A incorrect.
Nipple shields have their place in cases of weak suck or as a last resort in preserving the nursing relationship. Correcting positioning and latch should be the first technique.
C is a sophisticated distractor as bringing the infant's lower body into greater contact is often a technique for achieving better positioning and latch. However, we are basing the answer on the picture given which does not show the infant's bottom but does clearly show the infant with its neck turned awkwardly.
