The medical history includes hypertension and hyperlipidemia. The vital signs include: blood pressure 120/80 mm Hg, respiratory rate 25/min, heart rate 95/min, and temperature 37.0°C (98.5°F). He is admitted to the hospital. What do you expect the blood gas analysis to show?
ANon-anion gap metabolic acidosis
BMetabolic alkalosis
CRespiratory acidosis
DAnion gap metabolic acidosis
EMixed acid-base disorder
A 36-year-old male is taken to the emergency room after jumping from a building. Bilateral fractures to the femur were stabilized at the scene by emergency medical technicians. The patient is lucid upon questioning and his vitals are stable. Pain only at his hips was elicited. Cervical exam was not performed. What is the best imaging study for this patient?
AAP and lateral radiographs of hips
BLateral radiograph (x-ray) of hips
CMagnetic resonance imaging (MRI) of hips, knees, lumbar, and cervical area
DAnterior-posterior (AP) and lateral radiographs of hips, knees, lumbar, and cervical area
EComputed tomography (CT) scan of cervical spine, hips, and lumbar area
A 58-year-old man presents to the emergency department with a chief complaint of ringing in his ears that started several hours previously that has progressed to confusion. The patient denies any history of medical problems except for bilateral knee arthritis. He was recently seen by an orthopedic surgeon to evaluate his bilateral knee arthritis but has opted to not undergo knee replacement and prefers medical management. His wife noted that prior to them going on a hike today, he seemed confused and not himself. They decided to stay home, and roughly 14 hours later, he was no longer making any sense. Physical exam is notable for a confused man. The patient's vitals are being performed and his labs are being drawn. Which of the following is most likely to be seen on blood gas analysis?
ApH: 7.30, PaCO2: 15 mmHg, HCO3-: 16 mEq/L
BpH: 7.37, PaCO2: 41 mmHg, HCO3-: 12 mEq/L
CpH: 7.41, PaCO2: 65 mmHg, HCO3-: 34 mEq/L
DpH: 7.47, PaCO2: 11 mmHg, HCO3-: 24 mEq/L
EpH: 7.31, PaCO2: 31 mmHg, HCO3-: 15 mEq/L
