A client reports experiencing blurry central vision that has recently worsened. Which pathological process supports the client's subjective report?
Blockage of retinal capillaries causing ischemic damage of the central macular area.
Opaque spoke-like lines developing in the periphery of the lens to the center.
Tears in the retina that detach from the lining of the posterior eyeball.
An increase in intraocular pressure with loss of peripheral vision.
The Correct Answer is A
A) Blockage of retinal capillaries causing ischemic damage of the central macular area:
Correct. Blurry central vision that worsens over time can be indicative of macular ischemia, often caused by blockage of retinal capillaries leading to ischemic damage of the central macular area. This condition can occur in diseases such as diabetic retinopathy or retinal vein occlusion.
B) Opaque spoke-like lines developing in the periphery of the lens to the center:
This description is more characteristic of cataracts, which cause visual disturbances such as glare or halos around lights rather than blurry central vision.
C) Tears in the retina that detach from the lining of the posterior eyeball:
Retinal tears and subsequent detachment can cause visual disturbances, but they typically present as sudden onset of floaters, flashes of light, and a curtain-like shadow over the visual field rather than blurry central vision.
D) An increase in intraocular pressure with loss of peripheral vision:
This description is indicative of glaucoma, which can lead to loss of peripheral vision (visual field defects) rather than blurry central vision. Glaucoma-related visual field loss usually begins peripherally and progresses inward, affecting central vision in later stages.

Correct Answer is C
Explanation
Hypothyroidism is characterized by deficient production of thyroid hormones by the thyroid gland, leading to a decrease in circulating levels of triiodothyronine (T3) and thyroxine (T4). As a compensatory mechanism, the pituitary gland releases increased amounts of thyroid stimulating hormone (TSH) in an attempt to stimulate thyroid hormone production.
A) Increased triiodothyronine (T3) and thyroxine (T4) and decreased thyroid stimulating hormone (TSH):
This pattern of laboratory findings is not consistent with hypothyroidism. Hypothyroidism is characterized by decreased levels of T3 and T4 due to impaired thyroid function, leading to increased TSH levels as a compensatory response. Therefore, this option is incorrect.
B) Increased triiodothyronine (T3) and thyroid stimulating hormone (TSH):
While TSH levels are typically increased in hypothyroidism, T3 levels are usually decreased. Therefore, the combination of increased T3 and TSH is not indicative of hypothyroidism. This option is incorrect.
C) Decreased triiodothyronine (T3) and thyroxine (T4) and increased thyroid stimulating hormone (TSH):
Correct. In hypothyroidism, there is a decrease in both T3 and T4 levels due to impaired thyroid function. As a compensatory mechanism, the pituitary gland releases increased amounts of TSH to stimulate the thyroid gland. Therefore, this pattern of laboratory findings is consistent with hypothyroidism.
D) Decreased thyroid stimulating hormone (TSH), triiodothyronine (T3), and thyroxine (T4):
Decreased levels of TSH, T3, and T4 are not indicative of hypothyroidism. Hypothyroidism is characterized by elevated TSH levels and decreased T3 and T4 levels. Therefore, this option is incorrect.
Correct Answer is A
Explanation
A. Gastric carcinoma:
Helicobacter pylori infection is a known risk factor for the development of gastric carcinoma, or stomach cancer. Long-term follow-up is essential for clients treated for gastric ulcers caused by H. pylori infection to monitor for any signs or symptoms of gastric malignancy, such as persistent abdominal pain, unexplained weight loss, dysphagia, or gastrointestinal bleeding. Regular surveillance with endoscopic examinations may be recommended to detect any precancerous or cancerous changes in the gastric mucosa.
B. Hypokalemia:
Hypokalemia, or low potassium levels, is not directly associated with gastric ulcers caused by H. pylori infection. While certain medications used in the treatment of gastric ulcers, such as proton pump inhibitors (PPIs) or H2-receptor antagonists, may increase the risk of hypokalemia, it is not a long-term complication specifically related to H. pylori infection.
C. Kidney stones:
Kidney stones, or nephrolithiasis, are not directly associated with gastric ulcers caused by H. pylori infection. Kidney stones typically form in the kidneys and urinary tract due to factors such as dehydration, dietary factors, or metabolic disorders. While certain conditions, such as chronic kidney disease, may be associated with gastric ulcers, kidney stones are not a typical long-term complication.
D. Celiac disease:
Celiac disease is an autoimmune disorder characterized by an abnormal immune response to gluten, a protein found in wheat, barley, and rye. It is not directly associated with gastric ulcers caused by H. pylori infection. Celiac disease primarily affects the small intestine, leading to inflammation and damage to the intestinal lining in response to gluten ingestion. While individuals with celiac disease may experience gastrointestinal symptoms, they are not at increased risk for gastric ulcers specifically related to H. pylori infection.
