Final answer:
The parents demonstrate an understanding of the discharge instructions when they recognize the importance of using ankle-foot orthotics as prescribed for their child's postoperative care after clubfoot repair.
Step-by-step explanation:
Kali has prepared the discharge teaching for a 3-year-old after a repair to the Achilles tendon due to clubfoot. Kali knows that the parents understand the teaching when they say: "It will be important for us to use the ankle-foot orthotics as prescribed." This statement indicates that the parents understand the necessity of using the orthotics to maintain the corrected position of the foot and prevent a relapse. Parents need to ensure that their child wears ankle-foot orthotics as part of the treatment regime to keep the feet properly aligned post-surgery or casting.
