A nurse is caring for a patient diagnosed with cataracts.
What cue is consistent with cloudiness in the lens during the inspection of the eyes?

Redness in the sclera.

Pupil constriction.

Cloudiness in the lens.

Blurred vision.

Answer and Explanation

The Correct Answer is C

Choice A rationale

Redness in the sclera may indicate inflammation or infection but is not indicative of cataracts, which involve the lens of the eye.

Choice B rationale

Pupil constriction is not directly related to cataracts. Cataracts affect the lens clarity rather than pupil response.

Choice C rationale

Cloudiness in the lens is a hallmark sign of cataracts, which occur due to the lens becoming opaque, thereby obstructing light passage and impairing vision.

Choice D rationale

Blurred vision can result from various eye conditions, not specifically cataracts, which are characterized by lens cloudiness.

Correct Answer is D

Explanation

Choice A rationale

A decreased angle between the cuticles and the nails is not indicative of clubbing. In fact, it is often associated with healthy nails. Clubbing is recognized by changes that increase the angle between the nail bed and the cuticle.

Choice B rationale

An upward curving of the nails, known as koilonychia or spoon nails, is not characteristic of clubbing but is often associated with iron-deficiency anemia. Hence, this answer is incorrect for clubbing.

Choice C rationale

Blue nails indicate cyanosis, which is related to a lack of oxygen in the blood. This is distinct from clubbing, which is more about the shape and angle of the nails rather than their color.

Choice D rationale

Clubbing is recognized by an increase in the angle between the nail bed and the cuticle, often greater than 160 degrees. This is a hallmark feature and the correct indicator of clubbing.

A. Patient would be unable to pass the Snellen exam. B. Difficulty seeing from far or at a distance. C. Inability to see objects or letters close in range. D. Patient most likely will pass the Rosenbaum chart.

Correct Answer is C

Explanation

Choice A rationale

Patients with hyperopia (farsightedness) are able to see distant objects clearly but may have difficulty focusing on near objects. They can pass the Snellen exam, which measures distance vision, but may struggle with close-up tasks.

Choice B rationale

Hyperopia involves difficulty seeing close objects, not distant ones. Therefore, patients with hyperopia would not have difficulty seeing from far or at a distance, making this statement incorrect.

Choice C rationale

Hyperopia, or farsightedness, is characterized by the inability to see objects or letters that are close in range. It occurs when the eye's shape causes light to focus behind the retina instead of directly on it, leading to blurred near vision. Corrective lenses can help focus light properly on the retina.

Choice D rationale

The Rosenbaum chart is used to assess near vision acuity, which would highlight issues with hyperopia. However, patients with hyperopia would pass the Snellen exam, which tests distance vision, but might struggle with the Rosenbaum chart. .
