A nurse needs to assess the peripheral vision of a client. What test is appropriate?

A) Rosenbaum test: The Rosenbaum test is used to assess near vision and is typically performed with a handheld card to check for presbyopia, which is the difficulty seeing up close. It is not appropriate for testing peripheral vision, which is the focus of the current assessment.

B) Consensual constriction: Consensual constriction refers to the reaction of the pupil in the opposite eye when light is shined into one eye. This test assesses the pupillary light reflex, which evaluates how well the pupils constrict in response to light. It is not used to assess peripheral vision and focuses more on the function of the optic nerve and pupil reaction.

C) Corneal Light Reflex: The corneal light reflex is a test used to assess for strabismus (misalignment of the eyes) by checking the symmetry of the light reflection on the cornea. This test helps in diagnosing eye alignment issues, but it does not evaluate peripheral vision.

D) Confrontation test: The confrontation test is a straightforward and effective method used to assess peripheral vision. The nurse and patient sit facing each other, and the patient covers one eye while the nurse tests the other eye’s visual fields by moving their fingers in from the periphery. This test evaluates the patient's ability to detect objects in their peripheral vision and is specifically designed for this purpose.

A) Acromegaly: Acromegaly is a condition caused by excess growth hormone, leading to enlargement of bones and tissues, particularly in the hands, feet, and face. While facial features can appear more pronounced due to bone growth, acromegaly itself does not cause facial drooping as a prominent symptom. The condition does not typically present with the sudden onset of facial weakness or asymmetry associated with drooping.

B) Bell’s Palsy: Bell’s Palsy is a disorder that affects the facial nerve, leading to sudden, unilateral facial drooping or paralysis. It is often caused by inflammation of the facial nerve, and facial drooping is one of its hallmark symptoms. It usually occurs on one side of the face, causing weakness or loss of muscle tone, leading to the drooping appearance.

C) CVA (Cerebrovascular Accident): A CVA, or stroke, can result in facial drooping, typically on one side of the face, if the stroke affects areas of the brain controlling facial muscles. A common sign of a stroke is the sudden development of facial asymmetry, including drooping of the mouth or eyelid. It is an important symptom to monitor in assessing neurological function following a stroke.

D) Parkinson’s Disease: Parkinson’s disease can cause facial changes, such as reduced blinking and a "masked" appearance, but it does not typically cause facial drooping in the same way that Bell's Palsy or a CVA would. Parkinson’s-related facial changes stem from reduced movement rather than sudden weakness or paralysis of the facial muscles. While facial expression can be diminished, true drooping is less common.
