A nurse is teaching a client who has herpes simplex virus type 2 about disease transmission.
Which of the following statements by the client indicates understanding of the teaching?

Choice A rationale

Prednisone, a corticosteroid, can decrease calcium absorption in the gut and increase calcium excretion by the kidneys. Long-term use can lead to bone demineralization and osteoporosis. Vitamin D is essential for calcium absorption, so supplementation helps mitigate these effects and maintain bone health. Normal serum calcium levels range from 8.5 to 10.5 mg/dL.

Choice B rationale

Pantothenic acid (vitamin B5) is involved in various metabolic processes, and vitamin B6 is crucial for protein metabolism and nerve function. While important for overall health, there is no direct established link requiring their supplementation specifically due to prednisone therapy.

Choice C rationale

Biotin (vitamin B7) is involved in carbohydrate and fat metabolism, and vitamin B12 is essential for red blood cell formation and nerve function. There is no strong scientific evidence indicating a specific need for biotin and vitamin B12 supplementation during long-term prednisone treatment.

Choice D rationale

Folic acid (vitamin B9) is important for cell growth and DNA synthesis, and vitamin C (ascorbic acid) is an antioxidant involved in immune function and collagen synthesis. While beneficial for overall health, their supplementation is not specifically indicated to counteract the side effects of long-term prednisone therapy.

Choice A rationale

Glaucoma is characterized by damage to the optic nerve, often due to increased intraocular pressure. Without proper management to lower this pressure, the damage to the optic nerve progresses, leading to irreversible vision loss and eventually blindness.

Choice B rationale

The primary goal of glaucoma treatment with eye drops is to lower intraocular pressure and prevent further damage to the optic nerve, thereby preserving existing vision. Eye drops do not typically improve vision that has already been lost due to glaucoma.

Choice C rationale

Glaucoma is usually associated with impaired drainage or overproduction of aqueous humor, leading to increased intraocular pressure, not inadequate production of fluid. This elevated pressure is the primary risk factor for optic nerve damage.

Choice D rationale

Double vision (diplopia) is not a common or characteristic symptom of glaucoma. While various eye conditions can cause double vision, glaucoma primarily affects peripheral vision and visual acuity without causing diplopia. .
