Answer to Question 1

C
Children typically do not have 20/20 vision until age 6 or 7 years. A finding of 20/60 in a 4-year-old child is considered normal. Myopia is diminished distant vision, which is associated with a Snellen chart reading of 20/100 . Hyperopia is diminished near vision and is represented by a large fraction, such as 20/15; when found in people over age 45 it is known as presbyopia.

Answer to Question 2

C
The nurse should keep the door open and position herself so that the patient cannot block her exit from the room (stay between the patient and the door). The nurse should not enter a room with an angry patient by herself. The progression to physical violence is first anxiety, then verbal aggression, and finally physical aggression. The nurse's first priority in this situation is her own safety and the safety of others in the environment. The object is to relieve the patient's anxiety and not respond to anger with anger. Questioning about weapons, or being firm and defending against verbal aggression will likely provoke even more anger from the patient. The nurse must be calm and reassuring.
