A 21-year-old male presents to the emergency department after losing his footing and falling 20 feet off a construction scaffold. He hit his left side on a railing on the way down before landing on his left arm. He denies loss of consciousness during the event or feelings of lightheadedness. He has no significant past medical or surgical history and does not take any regular medications. Evaluation in the trauma bay revealed mild lacerations to the upper and lower extremities, pain to palpation in the distal left forearm, and bruising to the upper left quadrant of the abdomen as well as the lower left thorax. Free fluid was found in the abdomen by ultrasound, fluids were started, and he was rushed to the operating room for an exploratory laparotomy. A heavily lacerated spleen was discovered and removed. No other sources of bleeding were found. Further workup determined he suffered a non-displaced left distal radius fracture and non-displaced 9th and 10th rib fractures. Which of the following should be administered to this patient?
ATotal parenteral nutrition (TPN)
BProphylactic ceftriaxone
CPneumococcal vaccine
DNothing by mouth (NPO)
EOpen reduction internal fixation
A 66-year-old man is brought into the emergency department by his daughter for a change in behavior. Yesterday the patient seemed more confused than usual and was asking the same questions repetitively. His symptoms have not improved over the past 24 hours, thus the decision to bring him in today. Last year, the patient was almost completely independent but he then suffered a "series of falls," after which his ability to care for himself declined. After this episode he was no longer able to cook for himself or pay his bills but otherwise had been fine up until this episode. The patient has a past medical history of myocardial infarction, hypertension, depression, diabetes mellitus type II, constipation, diverticulitis, and peripheral neuropathy. His current medications include metformin, insulin, lisinopril, hydrochlorothiazide, sodium docusate, atorvastatin, metoprolol, fluoxetine, and gabapentin. On exam you note a confused man who is poorly kept. He has bruises over his legs and his gait seems unstable. He is alert to person and place, and answers some questions inappropriately. The patient's pulse is 90/minute and his blood pressure is 170/100 mmHg. Which of the following is the most likely diagnosis?
ANormal aging
BLewy body dementia
CVascular dementia
DPseudodementia (depression-related cognitive impairment)
EAlzheimer's dementia
