A 2-week-old infant presents to the emergency department with a 1-day history of decreased feeding, pallor, diaphoresis, and increasing somnolence. He was born at term, and the delivery was uncomplicated. On physical examination, his heart rate is 190 beats/min, his respiratory rate is 80 breaths/min, his blood pressure is 50/30 mm Hg, and his extremities are cool and pale with poor pulses. You place the infant on a cardiorespiratory monitor and begin your assessment and management.
Of the following, the MOST appropriate pair of tests to consider in this child is:
complete blood count and bone scan
electrocardiography and echocardiography
electroencephalography and head ultrasonography
lumbar puncture and head computed tomography scan
serum electrolytes and chest computed tomography scan
Sounds to me like he's just got a cold, probably due to a lowered immune system. Hence looking at the white blood cells and the marrow, just to be sure everything's dandy.
But he dual-boots with Windows 7.
electrocardiography and echocardiography
This baby most likely has congestive heart failure. A congenital heart disease frequently presents at around 2-4 weeks after birth.
i demand more of these!
And potatis - get out.
Windows Vista....hmm.
