PAX NLN Registered Nurse (RN) Vocabulary Practice Test

Think in terms of word parts that indicate body parts. The root that means foot is ped- (from Latin pes, pedis). Pedal is the form that conveys “relating to the foot” or something operated by the foot. You can see it in everyday use, like pedals on a bicycle or pedal extremities referring to the feet. The other terms point to different ideas: impend means something is about to happen, graphic pertains to drawing or written representation, and zoology is the study of animals. So pedal is the term that relates to the foot.
