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 D
Explanation
Choice A rationale
While individuals aged 19 to 30 years are generally at a lower risk for malignant melanoma compared to older adults, melanoma can still occur at any age, especially with certain risk factors. However, age alone does not significantly increase the risk of developing malignant melanoma without additional risk factors.
Choice B rationale
Hair color has minimal impact on the risk of developing malignant melanoma. Although individuals with fair skin and light hair have a higher risk of sunburn and subsequent melanoma, having dark hair does not significantly reduce the risk compared to other factors.
Choice C rationale
Female gender does not inherently increase the risk of developing malignant melanoma. Both males and females are at risk, although certain lifestyle factors and behaviors, such as sun exposure, can influence individual risk levels regardless of gender.
Choice D rationale
A history of repeated sunburn significantly increases the risk of developing malignant melanoma. Ultraviolet (UV) radiation from sunburns causes DNA damage in skin cells, leading to mutations that can result in melanoma. Repeated sunburns exacerbate this risk, making it a critical factor in melanoma development.
Correct Answer is A
Explanation
Choice A rationale
Pallor refers to the pale appearance of the skin due to decreased blood flow or decreased hemoglobin levels. It is often seen in conditions such as anemia, where there is a reduced number of red blood cells or hemoglobin, leading to a lack of the red-pink tones normally present in healthy skin.
Choice B rationale
Cyanosis refers to a bluish discoloration of the skin and mucous membranes due to inadequate oxygenation of the blood. It is often seen in respiratory or cardiovascular conditions where there is a decrease in oxygen levels. Cyanosis does not describe the absence of red-pink tones from decreased hemoglobin.
Choice C rationale
Jaundice refers to a yellow discoloration of the skin and eyes due to elevated levels of bilirubin in the blood. It is often seen in liver conditions or hemolysis. Jaundice is not related to decreased hemoglobin levels or the absence of red-pink tones in the skin.
Choice D rationale
Erythema refers to redness of the skin caused by increased blood flow to the capillaries in the dermis. It is often associated with inflammation, infection, or skin irritation. Erythema indicates increased blood flow, not decreased hemoglobin levels.
