A patient with an uncompensated respiratory alkalosis may have A. Been exposed to living at high altitudes. B. A reduced [H2CO3]:[HCO3- ] ratio. C. Neuromuscular hyperexcitability. D. An arterial pH of 7.3. E. A blood [H+] of 30 nmol/litre.

Answer»

A. False Living at high altitudes induces partial compensation, i.e. fall in [HCO3-

B. True This is consistent with alkalosis. 

C. True Alkalosis favours the development of tetany by increasing the binding power of plasma protein for ionic calcium. 

D. False This is an acidotic pH. 

E. True The normal level is 40 nmol/litre.
