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","C","D"]
Explanation
Choice A Reason:
Encouraging a high-sodium diet is essential for patients with Addison’s disease because they often suffer from hyponatremia (low sodium levels) due to the lack of aldosterone, a hormone that helps regulate sodium and potassium balance. Increasing sodium intake helps to counteract this deficiency and maintain proper electrolyte balance.
Choice B Reason:
Administering potassium supplements is not recommended for patients with Addison’s disease because they already have hyperkalemia (high potassium levels) due to the lack of aldosterone. Adding more potassium could exacerbate this condition and lead to serious complications such as cardiac arrhythmias.
Choice C Reason:
Administering intravenous corticosteroids is a critical intervention for managing Addison’s disease, especially during an adrenal crisis. Corticosteroids like hydrocortisone help replace the deficient hormones and stabilize the patient’s condition by reducing inflammation and supporting metabolic functions.
Choice D Reason:
Monitoring blood glucose levels regularly is important because patients with Addison’s disease can experience hypoglycemia (low blood sugar levels) due to cortisol deficiency. Regular monitoring helps in timely detection and management of hypoglycemia, preventing potential complications.
Choice E Reason:
Administering diuretics is not appropriate for patients with Addison’s disease as it can lead to further electrolyte imbalances, particularly worsening hyponatremia and hyperkalemia. Diuretics increase the excretion of sodium and potassium, which is counterproductive in managing Addison’s disease.
Correct Answer is D
Explanation
Choice A Reason:
Febrile non-hemolytic transfusion reactions (FNHTRs) are common and typically present with fever, chills, and sometimes rigors. However, they do not usually cause severe symptoms such as back pain and difficulty breathing. FNHTRs are generally less severe and are caused by the recipient’s immune response to donor white blood cells or cytokines in the transfused blood.
Choice B Reason:
Allergic reactions to blood transfusions can range from mild to severe. Mild reactions may include itching, hives, and rash, while severe reactions (anaphylaxis) can cause difficulty breathing and hypotension. However, allergic reactions do not typically cause back pain, which is more indicative of a hemolytic process.
Choice C Reason:
Fluid overload, also known as transfusion-associated circulatory overload (TACO), can occur when too much blood is transfused too quickly. Symptoms include dyspnea, hypertension, and pulmonary edema. While difficulty breathing is a symptom of fluid overload, chills and back pain are not typical features.
Choice D Reason:
Acute hemolytic transfusion reaction (AHTR) is the most likely cause of the patient’s symptoms. AHTR occurs when the recipient’s immune system attacks the transfused red blood cells, leading to their destruction. This reaction can cause severe symptoms such as chills, fever, back pain, and difficulty breathing. It is a medical emergency that requires immediate intervention to prevent serious complications, including kidney failure and shock.
