A patient is diagnosed with Homonymous Hemianopsia. The nurse expects to find what defects in the visual field of this patient:

the patient is unable to see in half of the visual field (same visual field) in each eye

the patient can see from one eye but not through the other one.

the patient is unable to see in half of the visual field (opposite visual field) in each eye

No visual impairment

Answer and Explanation

The Correct Answer is A

a) The patient is unable to see in half of the visual field (same visual field) in each eye:

Homonymous hemianopsia is a condition where there is a loss of vision in the same side of the visual field in both eyes. This occurs due to damage to the visual pathways after the optic chiasm, often from a stroke or brain injury, resulting in the loss of either the right or left visual field in both eyes.

b) The patient can see from one eye but not through the other one:

This description fits a condition called monocular blindness, which is typically caused by damage to the optic nerve before it reaches the optic chiasm. Homonymous hemianopsia involves both eyes and specific visual fields, not complete loss of vision in one eye.

c) The patient is unable to see in half of the visual field (opposite visual field) in each eye:

This option describes bitemporal hemianopsia, which results in loss of vision in the outer (temporal) fields of both eyes and is often due to damage at the optic chiasm. Homonymous hemianopsia involves the same side of the visual field in both eyes, not the opposite visual fields.

d) No visual impairment:

Homonymous hemianopsia is characterized by significant visual impairment, specifically the loss of half the visual field in both eyes on the same side. Therefore, it is incorrect to say there is no visual impairment with this condition.

Correct Answer is A

Explanation

A) Dehydration:

When the skin remains tented and returns to its normal position slowly after being pinched, it indicates decreased skin turgor, which is a clinical sign of dehydration. Dehydration can occur due to fluid loss from sweating during vigorous physical activity like a beach tournament.

B) Hypervolemia:

Hypervolemia refers to excess fluid volume in the body, which would typically manifest with signs such as peripheral edema or jugular vein distention rather than decreased skin turgor.

C) Properly Hydrated:

Properly hydrated individuals would have normal skin turgor, where the skin returns promptly to its normal position after being pinched.

D) Infection:

Skin tenting is not a specific sign of infection. Infection would typically present with localized signs such as redness, warmth, swelling, and possibly systemic signs like fever.

A. Electrical cords are placed along the walls. B. Handrails are present in the bathroom. C. Uses a microwave for cooking. D. Scatter rugs are present in the kitchen.

Correct Answer is D

Explanation

A) Electrical cords are placed along the walls: While it is important to ensure that electrical cords are safely managed, cords placed along the walls are less likely to pose a tripping hazard compared to those that are left loose or run across walking paths. This setup, in itself, is generally not a significant safety risk if managed properly.

B) Handrails are present in the bathroom: Handrails in the bathroom are actually a safety feature, not a risk. They provide necessary support for older adults with decreased vision or mobility issues, helping to prevent falls when using the toilet or getting in and out of the bathtub or shower.

C) Uses a microwave for cooking: Using a microwave for cooking is generally considered safe for individuals with decreased vision, as it minimizes the risk of burns and other injuries associated with using a stove or oven. The microwave can be a safer cooking method if the client is familiar with its operation.

D) Scatter rugs are present in the kitchen: Scatter rugs are a significant safety risk, especially for older adults with decreased vision. These rugs can easily cause trips and falls, leading to potentially serious injuries. Removing scatter rugs or securing them with non-slip backing can help mitigate this risk and create a safer home environment.
