A 74-year-old male presents to your clinic with complaints of seeing “wavy lines” in the visual field of his left eye. He is not sure when it started but does believe it has gotten progressively worse. He denies pain, photophobia, or other ocular symptoms. His PMH is significant for Type II Diabetes and HTN. His current medications include metformin and lisinopril. On examination, his visual acuity is 20/400 in the left eye and 20/70 in the right eye.

A 74-year-old woman with PMH of hypertension, diabetes, CAD, and osteoarthritis came to the clinic with her son for assessment of her worsening cognitive decline. The son is concerned about her short-term memory problems for the past 10 months. The patient had a fall 10 months ago; after that fall, she started to ask the same questions over and over again. The patient had another fall 4 months ago and also an episode of dizziness 2 months ago. With these incidents, her son noticed further decline in cognition. Recently, her son noticed that she has become a bit more suspicious of her daughter-in-law and has been hoarding things. She has lost interest in her day-to-day activities and forgets to include the right ingredients when cooking. Family members have to remind her to take her medications, and her son is helping with the management of her finances. On the Mini-Mental Status Examination (MMSE), the patient scored 21/30 with abnormal clock drawing. On the Geriatric Depression Scale (GDS-15), the patient scored 2/15. CT scan of the head showed multiple lacunar infarcts in the right basal ganglia and left cerebellar region. Based on this information, which of the following conditions is the most likely cause of this patient’s cognitive decline?

A 74-year-old male with a PMH significant for 50-pack-year cigarette use, presents for evaluation of worsening cough and one episode of hemoptysis.  Other than nicotine stains present on his left index and middle fingers, his physical examination is unremarkable.  CXR reveals a 4 cm. right lung mass.  Serum sodium is 125 mEq/L (↓), BUN 12 mg/dL, creatinine 1.1mg/dL. Serum osmolality is 260 mOsm/L (↓), and urine sodium is 50 mEq/L (↑).  The patient’s mucous membranes are moist, skin turgor is normal, and he does not demonstrate orthostatic change in BP.  He currently takes no prescription or OTC medications or supplements.  TSH level is normal.  Based on this information, which of the following conditions is the most likely etiology of this patient’s hyponatremia?
