Three IV boluses of 0.9% saline were administered during the past 2 hours, and her serum glucose concentration ahs decreased from 874 mg/dL to 400 mg/dL during this time. She responds to painful stimuli only. Her temperature is 97.9, pulse 56/min, respirations 12/min, and BP is 146/88. Fundoscopic examination shows absence of venous pulsations. Physical examination shows no abnormalities. Which of the following is the most likely cause of this patient’s altered mental status?
A) Cerebral edema
B) Hypoglycemia
C) Hypovolemia
D) Metabolic Acidosis (WRONG)
E) Persistent hyperglycemia
A 12-hour-old female newborn becomes irritable, has difficulty breathing and then has a 2-minute generalized tonic-clonic seizure. She was born at 36 WGA by c-section for breech presentation and weighed 3997g. Her mother had gestational diabetes poorly controlled with diet, she refused insulin therapy. Apgar were 7/8 at 1/5 minutes. Exam shows decreased tone and lethargy. Pulse ox shows sat of 99%. EKG shows prolonged QT interval. In addition to measurement of serum glucose concentration, the most appropriate next step is measurement of:
A) Bicarbonate
B) Bilirubin
C) Calcium
D) Magnesium (WRONG)
E) TSH
A 6 month old boy is broght ot doctor because of 1 day history of fever and foul smelling urine. UA shows 30-50 WBC/hpf, positive nitrites, and positive leukocyte esterase. Urine culture grows E. coli. ABX therapy is initiated, and his syptoms resolve. Renal ultrasound shows no abnormalities. Which of the following is the most appropriate next step in management?
A) observation for recurrent symptoms (WRONG)
B) Repeat urine culture in 3 months
C) Intravenous pyelography
D) Voiding cystourethrography
E) Cytoscopy
A 3 year old girl comes to ED 10 minutes after an episode of syncope followed by generalized tonic clonic movements lasting 30 seconds. Two minutes after the episode she is fully alert. On arrival she stops talking, closes her eyes, and has 3 to 4 rhgytmic jerks of the right upper extremity. During the episode an ECG shows P waves at 80/min with no QRS complexes, NSR resumes in 20 seconds. One minute later she is fully alert. Which of the following is the most likely Dx?
A) Absence seizure
B) Adams-Stokes attack
C) Adverse effect of medication
D) Breath-holding episode (WRONG)
E) Carotid artery trauma
F) Narcolepsy cataplexy
G) Vasovagal syncope
H) Ventricular tachyarrhytmia
