A nurse is performing a complete physical examination on a patient. After examining the patient with the Snellen chart, the nurse documented distance vision in both eyes 20/40. The patient asks the nurse what 20/40 means:

20 represents the distance you are placed from the chart and 40 represents the distance a normal eye read the chart.

20 represents the distance a normal eye can read and 40 represents the distance your eye read the chart.

20 represents the distance you are placed from the chart and 40 represents the distance your eye read the chart.

40 represents the distance you are placed from the chart and 20 represents the distance a normal eye read the chart.

Answer and Explanation

The Correct Answer is A

A. 20 represents the distance you are placed from the chart and 40 represents the distance a normal eye reads the chart:

This is correct. The first number (20) represents the distance in feet the patient is from the Snellen chart. The second number (40) indicates the distance at which a person with normal vision can read the same line. Therefore, 20/40 means that what the patient can read at 20 feet, a person with normal vision can read at 40 feet.

B. 20 represents the distance a normal eye can read and 40 represents the distance your eye reads the chart:

This is incorrect. The first number should represent the distance the patient is from the chart, not the normal eye's reading distance.

C. 20 represents the distance you are placed from the chart and 40 represents the distance your eye reads the chart:

This is incorrect. While the first number is correct (the distance from the chart), the second number should represent the distance a person with normal vision can read the same line, not the patient's distance.

D. 40 represents the distance you are placed from the chart and 20 represents the distance a normal eye reads the chart:

This is incorrect. The standard for visual acuity measurements is that the first number represents the testing distance (usually 20 feet), and the second number represents the distance at which a normal eye can read the line.

Correct Answer is A

Explanation

A) Presbyopia: Presbyopia is an age-related condition where the lens of the eye loses elasticity, making it harder to focus on close objects. This condition typically begins to affect individuals around the age of 40, causing them to hold reading materials farther away to see them clearly. The client's complaint aligns perfectly with this common symptom of presbyopia.

B) Cataracts: Cataracts involve the clouding of the eye's lens, leading to overall blurry vision, glare, and difficulty with night vision. Although cataracts can interfere with reading, they do not specifically cause the need to hold reading materials farther away, which is more indicative of presbyopia.

C) Tropia: Tropia is a type of strabismus where one eye deviates from normal alignment, leading to symptoms like double vision or eye strain. This condition affects how the eyes coordinate but does not typically cause the specific symptom of needing to hold reading materials farther away.

D) Myopia: Myopia, or nearsightedness, results in clear vision for close objects but blurry vision for distant objects. The client's issue of needing to hold reading materials farther away to see clearly is inconsistent with myopia, which would cause difficulty with distant vision instead.

A. "Let's discuss your risk factors for heart disease." B. "We should review the amount of protein in your diet." C. "Waist circumference can vary over the course of the day." D. "You probably have a vitamin deficiency."

Correct Answer is A

Explanation

A) "Let's discuss your risk factors for heart disease.":

A waist circumference of 43 inches (109 cm) in a male is considered elevated and indicates central obesity, which is a significant risk factor for cardiovascular diseases, including heart disease, hypertension, and type 2 diabetes. Addressing this finding by discussing risk factors for heart disease is appropriate and necessary for preventive healthcare.

B) "We should review the amount of protein in your diet.":

While diet is important, protein intake is not directly related to waist circumference. The primary concern with a large waist circumference is the associated risk of metabolic and cardiovascular conditions, rather than specific macronutrient consumption.

C) "Waist circumference can vary over the course of the day.":

Though there can be minor variations in waist circumference throughout the day due to factors like fluid retention or meals, a measurement of 43 inches is significantly above the threshold indicating central obesity. This warrants a discussion about health risks rather than focusing on daily fluctuations.

D) "You probably have a vitamin deficiency.":

Vitamin deficiencies are not directly indicated by waist circumference measurements. This statement is not appropriate given the finding, as the primary concern with a large waist circumference is its association with increased risk of chronic diseases rather than nutrient deficiencies.
