(1) 2mnth old boy has 6wk h/o diarhea and vomiting esp. after formula feeds. he has a 113grams weight loss since birth and currently weighs 3.1kg and ht is 51cm. he appears irritable and o/e jaundice+, lungs-nrml, cvs-nrml. liver- is palpable 2-3cms below the costal margin and spleen 1-2 cms below the costal margin. serum glucose- 35mg/dl, bilirubin (total) is 2.3mg/dl. urine glucose- negative, urine reducing sub's 3+. MOST LIKELY MECHANISM?
A- DECREASED GLUCONEOGENESIS
B- INCREASED "
C- INCREASED GLUCAGON SECRETION
D- INCREASED INSULIN SECRETION
E- DECREASED "
F- INSULIN RESISTANCE
(2) 28 yr old female develops arthopnea and fatigue 3wks afetr normal delivery. BP and pulse normal. crackles heard at both lung bases. the point of max. impulse is laterally displaced and diffuse. S3+. there is 2+ pedal edema. chest x-ray- vascular cephalization of pulm vasculature and kerly b lines. most appropriate next step?
A- MEASURE CKMB AND LDH
