The nurse is speaking to the client and suspects a weakness in eye muscle after observing the eyes cross.
What test should the nurse administer to further assess this problem?

Cover/Uncover test.

Testing peripheral vision.

Snellen chart test.

Weber test.

Answer and Explanation

The Correct Answer is A

Choice A rationale

The Cover/Uncover test is used to assess the presence of strabismus or eye muscle weakness. During this test, one eye is covered while the other eye is observed for movement. The uncovered eye is then observed when the cover is removed. If there is a misalignment or weakness, the uncovered eye will move to re-establish focus, indicating a problem with eye muscle control.

Choice B rationale

Testing peripheral vision involves assessing the range of vision around the central focus point and is not specifically used to detect eye muscle weakness. It evaluates the function of the retina and optic nerve rather than the eye muscles. This test helps identify issues such as glaucoma or retinal detachment.

Choice C rationale

The Snellen chart test measures visual acuity, specifically how well a person can see at various distances. It is not designed to assess eye muscle strength or alignment. The test involves reading letters of different sizes from a chart placed at a standard distance.

Choice D rationale

The Weber test is an auditory test used to assess hearing loss by placing a vibrating tuning fork on the forehead or middle of the head. It helps determine whether hearing loss is conductive or sensorineural in nature. This test does not provide information about eye muscle function or alignment.

Correct Answer is B

Explanation

Choice A rationale

An elliptical chest describes the typical shape of a healthy chest with a lateral dimension greater than the anteroposterior dimension. This shape allows for normal expansion and contraction of the lungs during breathing. An elliptical chest does not indicate any deformity or abnormality in the sternum or costal cartilage.

Choice B rationale

Pectus excavatum, also known as funnel chest, is a congenital deformity where the sternum and costal cartilage are sunken inward, creating a concave appearance of the chest. This condition can range in severity and may affect respiratory function and exercise tolerance in some individuals. Surgical correction may be considered for severe cases.

Choice C rationale

A standard chest describes a chest without any deformities or abnormalities, typically with a normal elliptical shape. This term does not denote any specific condition or configuration and implies a healthy, non-deformed chest.

Choice D rationale

Barrel chest is characterized by an increased anteroposterior diameter of the chest, giving it a round or barrel-like appearance. This condition is often seen in individuals with chronic obstructive pulmonary disease (COPD) or emphysema, where the lungs are chronically overinflated, causing the chest to expand and lose its normal shape.

A. Redness in the sclera. B. Pupil constriction. C. Cloudiness in the lens. D. Blurred vision.

Correct Answer is C

Explanation

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.
