The nurse assesses the patient's visual acuity to be 20/25 using an eye chart. The patient asks what that means. Which of the following is the nurse’s best response?

You can read the chart perfectly with both eyes.

You can read 25 feet what most people can read at 20 feet.

You can read at 20 feet what most people can read at 25 feet.

Your left eye can see the chart at 20 feet while your right eye can see it at 25 feet.

Answer and Explanation

The Correct Answer is C

A visual acuity of 20/25 means that the patient can read letters on an eye chart at 20 feet away, which is the same as what someone with normal vision can read at 25 feet away. This indicates that the patient's visual acuity is slightly below average, but still within the normal range.

Correct Answer is C

Explanation

REM (Rapid Eye Movement) sleep is a stage of sleep that is part of the sleep cycle, which also includes non-REM (NREM) sleep. Dreaming occurs during REM sleep, and it usually composes about 20-25% of total sleep time in adults. NREM sleep, on the other hand, makes up the largest amount of total sleep time, typically about 75-80%. Both REM and NREM sleep are important for restorative sleep, but each plays a diﬀerent role in physiological and cognitive functioning.

A. Umbilicus B. Midclavicular lines C. Sternum D. Lower border of the right ribs.

Correct Answer is ["A"]

Explanation

To map the client's abdomen into four quadrants, the nurse should use the umbilicus as the landmark to perform this assessment. The abdomen is divided into four quadrants by drawing an imaginary line from the center of the umbilicus to the pubic symphysis and another line from the center of the umbilicus to the xiphoid process of the sternum. This helps in identifying the location of any potential abdominal discomfort or tenderness.
