A 68-year-old patient presents to the clinic with complaints of gradually worsening vision. Upon examination, the nurse notes that the patient has difficulty seeing at night, increased sensitivity to glare, and a noticeable cloudiness in the lens of the eyes. Which clinical manifestation is most indicative of cataracts?
Cloudiness in the lens of the eyes
Double vision in one eye
Eye pain and redness
Sudden loss of vision
The Correct Answer is A
Choice A Reason:
Cloudiness in the lens of the eyes is the hallmark symptom of cataracts. Cataracts cause the lens to become opaque, leading to blurred vision and difficulty seeing clearly. This cloudiness can make it challenging to perform everyday tasks and is the most indicative sign of cataracts.
Choice B Reason:
Double vision in one eye can occur with cataracts, but it is not the most indicative symptom. While cataracts can cause visual disturbances, the primary symptom is the cloudiness of the lens, which directly impacts vision clarity.
Choice C Reason:
Eye pain and redness are not typical symptoms of cataracts. These symptoms are more commonly associated with other eye conditions such as infections or glaucoma. Cataracts primarily cause visual disturbances without significant pain or redness.
Choice D Reason:
Sudden loss of vision is not characteristic of cataracts. Cataracts develop gradually over time, leading to a slow progression of vision impairment. Sudden vision loss is more likely to be associated with acute conditions such as retinal detachment or vascular occlusions.

Correct Answer is A
Explanation
Choice A Reason:
Storing hearing aids in a dry, cool place when not in use is crucial for maintaining their functionality and longevity. Moisture and heat can damage the delicate electronic components of hearing aids. Using a dehumidifier specifically designed for hearing aids can help prevent moisture buildup and extend the life of the devices.
Choice B Reason:
Using cotton swabs to clean the interior components of the hearing aid is not recommended. Cotton swabs can push debris further into the hearing aid and potentially damage the internal components. Instead, specialized cleaning tools such as wax loops, brushes, and earmold tubing blowers should be used to clean hearing aids properly.
Choice C Reason:
It is not okay to wear hearing aids while showering or swimming. Most hearing aids are water-resistant but not waterproof. Exposure to water can damage the hearing aids and affect their performance. It is important to remove hearing aids before any activities involving water.
Choice D Reason:
Replacing the batteries of hearing aids once a month regardless of usage is not necessary. Battery life depends on the type of hearing aid, the battery size, and the amount of usage. It is more practical to replace the batteries when they are low or depleted, as indicated by the hearing aid’s low battery warning.
Correct Answer is B
Explanation
Choice A Reason:
A random blood glucose level of 126 mg/dL is not typically indicative of hyperglycemia. Hyperglycemia is generally defined as a blood glucose level above 180 mg/dL. A level of 126 mg/dL is closer to the threshold for diagnosing diabetes but does not necessarily indicate hyperglycemia.
Choice B Reason:
A history of poor wound healing is a common manifestation of hyperglycemia. High blood sugar levels can impair the body’s ability to heal wounds by affecting blood flow and the function of immune cells. This can lead to prolonged wound healing times and an increased risk of infections.
Choice C Reason:
Decreased urinary output is not a typical symptom of hyperglycemia. In fact, hyperglycemia often causes increased urinary output (polyuria) due to the body’s attempt to excrete excess glucose through urine. Decreased urinary output could be indicative of other conditions, such as dehydration or kidney issues.
Choice D Reason:
Clammy skin is more commonly associated with hypoglycemia (low blood sugar) rather than hyperglycemia. Hypoglycemia can cause symptoms such as sweating, shakiness, and clammy skin due to the body’s response to low blood sugar levels. Hyperglycemia, on the other hand, does not typically cause clammy skin.
