Which equation is incorrect?
A)anion gap =(Na+ + K+) - (Cl- + HCO??)
B)calculated serum osmolality = 2(Na + urea +glucose)
C)paO? = pIO? - paCO?/0.8
D)the expected CO? in metabolic acidosis = 1.5 × HCO?? + 8
E)the expected CO? in metabolic alkalosis =0.9× HCO?? + 9

Question

Quizplus · Accepted Answer

The correct formula for calculated serum osmolality is 2(Na+) + (Glucose / 18) + (BUN / 2.8) or a similar variation depending on the units used for glucose and urea (BUN - Blood Urea Nitrogen). The formula provided in option B incorrectly adds urea and glucose directly to sodium without accounting for their units or conversion factors.
