A nurse is providing education for a client who has glaucoma.
Which of the following statements should the nurse include in the teaching?
Without treatment, glaucoma can cause blindness.
Double vision is a common symptom of glaucoma.
Glaucoma is caused by inadequate production of fluid within the eye.
Use of eye drops will improve vision over time.
The Correct Answer is A
Choice A rationale
Without treatment, glaucoma can lead to blindness due to the progressive damage it causes to the optic nerve. Elevated intraocular pressure damages the optic nerve fibers, leading to peripheral vision loss and eventually total blindness if untreated.
Choice B rationale
Double vision is not a common symptom of glaucoma. Instead, glaucoma typically presents with symptoms like gradual peripheral vision loss, eye pain, and halos around lights.
Choice C rationale
Glaucoma is primarily caused by increased intraocular pressure, either due to overproduction of aqueous humor or improper drainage, not inadequate fluid production.
Choice D rationale
Use of eye drops helps to control intraocular pressure but does not improve vision; it helps to prevent further damage to the optic nerve.

Correct Answer is ["B","E"]
Explanation
Choice A rationale
Patches of eschar covering parts of the wound are characteristic of more advanced pressure ulcers, such as Stage III or IV, where necrotic tissue is present. Eschar is a dark, thick, leathery scab or crust that indicates deeper tissue damage and is not observed in Stage II pressure ulcers.
Choice B rationale
A Stage II pressure ulcer is characterized by partial thickness skin erosion with loss of the epidermis and dermis. It appears as a shallow open ulcer with a red-pink wound bed, indicating that the damage has not extended beyond these layers of skin.
Choice C rationale
When a pressure ulcer extends into the subcutaneous tissue, it is classified as a Stage III or IV ulcer, depending on the depth and extent of tissue involvement. Stage II ulcers are limited to the epidermis and dermis and do not reach the subcutaneous layer.
Choice D rationale
Intact skin that appears red but is not broken is indicative of a Stage I pressure ulcer, which represents the earliest stage of pressure injury. Stage I ulcers involve non-blanchable erythema (redness) but no open wound or skin erosion.
Choice E rationale
Open blister areas with a red-pink wound bed are characteristic of Stage II pressure ulcers. These ulcers exhibit partial thickness skin loss and can present as open or fluid-filled blisters with a visible wound bed.
Choice F rationale
Localized redness in light skin that blanches with fingertip pressure is typical of a Stage I pressure ulcer. Blanching erythema indicates that the skin is still viable and blood flow is present, which differentiates Stage I from more advanced stages of pressure injury.
Correct Answer is A
Explanation
Choice A rationale
Vitiligo is a condition caused by the destruction or malfunction of melanocytes, the cells responsible for producing melanin pigment. This leads to the development of white patches on the skin, as melanin is absent in these areas. Vitiligo is an autoimmune condition and can affect any part of the body, including the skin, hair, and mucous membranes.
Choice B rationale
Excess apocrine glands in the feet are not related to vitiligo. Apocrine glands are sweat glands found primarily in the underarm and genital areas and are responsible for the secretion of a thick, odorless fluid. Their overactivity does not result in the white patches seen in vitiligo.
Choice C rationale
Impetigo is a bacterial skin infection characterized by red sores, blisters, and crusting. It is not related to vitiligo and does not cause depigmentation. Impetigo is treated with antibiotics, whereas vitiligo requires different management strategies to address the loss of pigment.
Choice D rationale
Vitiligo is not caused by an excess of melanin pigment. Rather, it is the result of melanin loss or the absence of melanocytes in certain areas of the skin, leading to the characteristic white patches.
