1
Q
What is the cause of accentuated P2 in COPD patients
A
increase pulmonary pressure causes early closing of P2
2
Q
How do diuretic cause metabolic alkalosis?
A
wasting of chloride anions cause the kidney to retain HCO3- to retain electrical neutrality
3
Q
How do you calculate anion gap?
A
Na+- Cl- - HCO3- (can be calculated by rule of 10- change in HCO3- by 10 for each 0.01 change in pH)
4
Q
When anion gap is not appropriately matched by a reduction in HCO3-, what can we conclude?
A
suggests the presence of a primary abnormality increasing the concentration of HCO3-, a primary alkalosis
