The nurse measures a male client's waist circumference as 43 inches (109 cm). Which statement is most appropriate for the nurse to make given this finding?

A) Loss of vision in one eye:

Loss of vision in one eye is not related to hyperopia (farsightedness). This condition could be due to various other causes such as retinal detachment, optic neuropathy, or trauma, but it does not describe the refractive error associated with hyperopia.

B) Clear vision of nearby objects, but difficulty seeing distant objects:

This description pertains to myopia (nearsightedness), where individuals can see nearby objects clearly but struggle with seeing distant objects. Hyperopia is the opposite, involving difficulty with near vision rather than distance vision.

C) Clear vision of distant objects, but difficulty seeing nearby objects:

Hyperopia, or farsightedness, is characterized by clear vision of distant objects while nearby objects appear blurry. This occurs because the eye's light focuses behind the retina rather than directly on it, making close-up tasks like reading challenging.

D) Blurry vision of both distant and nearby objects:

Blurry vision of both distant and nearby objects is not specific to hyperopia and may indicate other eye conditions such as astigmatism or severe refractive errors that affect overall visual acuity, rather than the specific issue of near vision seen in hyperopia.

(a) Soles of the feet:

The soles of the feet are not considered the most reliable indicator of central cyanosis because peripheral areas can be affected by various factors, including temperature and circulation. Changes in color here might not accurately reflect central oxygenation status.

(b) Oral mucosa:

The oral mucosa is the most reliable indicator of central cyanosis because it reflects the oxygenation status of the central circulatory system. Cyanosis in this area indicates a significant drop in arterial oxygen saturation and is a more direct indicator of hypoxemia compared to peripheral sites.

(c) Ear lobes:

Ear lobes, like the soles of the feet, can be influenced by peripheral circulation and environmental factors. While cyanosis can be observed here, it is not as reliable as central sites like the oral mucosa for assessing systemic oxygenation.

(d) Conjunctivae:

The conjunctivae can show signs of cyanosis, but the oral mucosa is still a more sensitive and reliable indicator for central cyanosis. The oral mucosa provides a clear and consistent site to assess oxygenation in emergency situations.
