Write answer in between .Q:A 65-year-old woman comes to the emergency department because of blurry vision for 10 hours. She has also had urinary urgency and discomfort while urinating for the past 4 days. She has been feeling increasingly weak and nauseous since yesterday. She has a history of type 2 diabetes mellitus and arterial hypertension. One year ago she was treated for an infection of her eyes. She drinks 23 glasses of wine weekly. Current medications include captopril, metoprolol, metformin, and insulin. Her temperature is 37.5C 99.5F, pulse is 107min, and blood pressure is 9570 mm Hg. Visual acuity is decreased in both eyes. The pupils are equal and reactive to light. The corneal reflexes are brisk. The mucous membranes of the mouth are dry. The abdomen is soft and not distended. Cardiopulmonary examination shows no abnormalities. Which of the following is the most likely diagnosis?? A: Ischemic optic neuropathy, B: Hypoglycemia, C: Posterior uveitis, D: Hyperosmolar hyperglycemic state, E: Alcoholic ketoacidosis,  <response>: Based on the information provided in the question stem, the most relevant findings are:- 65-year-old woman with blurry vision, urinary symptoms, weakness and nausea- History of type 2 diabetes mellitus and hypertension- Vital signs show tachycardia, hypotension, fever- Decreased visual acuity, dry mucous membranes- No abnormalities on cardiovascular or pulmonary examThe key finding here is the very high blood sugar hyperglycemia evidenced by the symptoms of polyuria, polydipsia, weakness, nausea, and decreased vision. This, combined with her history of poorly controlled type 2 diabetes, makes diabetic hyperosmolar hyperglycemic state HHS the most likely diagnosis. The other choices can be ruled out:- Ischemic optic neuropathy - no evidence of vascular occlusion- Hypoglycemia - symptoms point to very high blood sugar- Posterior uveitis - no indication of inflammatory eye disease- Alcoholic ketoacidosis - no severe metabolic acidosis or history of recent heavy alcohol useD: Hyperosmolar hyperglycemic state
