Final answer:
Plantar flexion is a foot movement in which the heel is lifted off the ground. It is caused by the contraction of the calf muscles. There are no specific nurse interventions to prevent plantar flexion, but proper foot care and stretching exercises can help prevent discomfort.
Step-by-step explanation:
Plantar flexion is a foot movement at the ankle in which the heel is lifted off of the ground. It is commonly seen when standing on tiptoes.
The primary cause of plantar flexion is the contraction of the calf muscles, specifically the gastrocnemius and soleus muscles.
There are no specific interventions by the nurse to prevent plantar flexion as it is a normal and necessary movement. However, maintaining proper foot care, wearing supportive shoes, and performing regular stretching exercises can help prevent any associated discomfort or problems.
