Quizplus · Accepted Answer

Plantar flexion is the expected response of the Achilles deep tendon reflex. Extension of the right lower leg is the expected response for the patellar deep tendon reflex. Plantar flexion of the right toes is the expected response for the plantar reflex (Babinski). Dorsiflexion of the right foot is an incorrect response because the nurse is holding the patient's foot in dorsiflexion, therefore dorsiflexion would not be an expected response.
