His temperature is 99.2°F (37.3°C), blood pressure is 90/65 mmHg, pulse is 152/min, respirations are 16/min, and oxygen saturation is 100% on room air. Physical exam is notable for a young man who opens his eyes spontaneously and is looking around. He answers questions with inappropriate responses but discernible words. He withdraws from pain but does not have purposeful movement. Which of the following is this patient's Glasgow coma scale?

A 53-year-old man is brought to the emergency department for confusion. He was in his usual state of health until about 3 hours ago when he tried to use his sandwich to turn off the TV. He also complained to his wife that he had a severe headache. Past medical history is notable for hypertension, which has been difficult to control on multiple medications. His temperature is 36.7°C (98°F), the pulse is 70/min, and the blood pressure is 206/132 mm Hg. On physical exam he is alert and oriented only to himself, repeating over and over that his head hurts. The physical exam is otherwise unremarkable and his neurologic exam is nonfocal. The noncontrast CT scan of the patient's head is shown and reveals an acute intraparenchymal hemorrhage in the basal ganglia. Which of the following diagnostic tests would be most helpful in determining the underlying cause of this patient's hemorrhage?
ALumbar puncture
BElectroencephalogram (EEG)
CMRI of the brain
DCT angiography of the neck
ECT angiography of the brain
A 69-year-old male presents to the emergency department for slurred speech and an inability to use his right arm which occurred while he was eating dinner. The patient arrived at the emergency department within one hour. A CT scan was performed of the head and did not reveal any signs of hemorrhage. The patient is given thrombolytics and is then managed on the neurology floor. Three days later, the patient is recovering and is stable. He seems depressed but is doing well with his symptoms gradually improving as compared to his initial presentation. The patient complains of neck pain that has worsened slowly over the past few days for which he is being given ibuprofen. Laboratory values are ordered and return as indicated below: Serum: Na+: 130 mEq/L K+: 3.7 mEq/L Cl-: 100 mEq/L HCO3-: 24 mEq/L Urea nitrogen: 7 mg/dL Glucose: 70 mg/dL Creatinine: 0.9 mg/dL Ca2+: 9.7 mg/dL Urine: Appearance: dark Glucose: negative WBC: 0/hpf Bacterial: none Na+: 320 mEq/L/24 hours His temperature is 99.5°F (37.5°C), pulse is 95/min, blood pressure is 129/70 mmHg, respirations are 10/min, and oxygen saturation is 98% on room air. Which of the following is the best next step in management?
ADemeclocycline
BFluid restriction
