Final answer:
The nurse practitioner would interpret 20/60 vision as the patient being able to see at 20 feet what a person with normal vision can see at 60 feet.
Step-by-step explanation:
When a nurse practitioner interprets a patient’s vision as 20/60, it means that the patient can see at 20 feet what a person with normal vision can see at 60 feet. This is determined using a Snellen chart, which assesses visual acuity by presenting letters of varying sizes. A person with normal vision would be able to see the smallest letters from 60 feet away that a person with 20/60 vision can only see from 20 feet away.
