Q

Ethylene glycol intoxication

A

Metabolic acidosis
Produces glycolic and oxalic acid
Increased anion gap

17
Q

Diarrhea

A

Metabolic acidosis
GI loss of HCO3
Normal anion gap

18
Q

Type 1, 2, 4 RTA

A

Metabolic acidosis
1 failure to excrete titratable acid and NH4, normal AG
2 renal loss of bicarbonate
4 hypoaldosteronism, failure to excrete NH4, hyperkalemia caused by lack of aldosterone inhibits NH3 synthesis, normal anion gap

19
Q

Vomiting

A

Metabolic alkalosis

Loss of gastric H, hypo K, volume contraction, may have increase anion gap due to increased ketoacids in starvation

20
Q

Hyperaldosteronism

A

Metabolic alkalosis

Increased H secretion by distal tubule, increased new HCO3 reabsorption

21
Q

Loop or thiazide diuretics

A

Metabolic alkalosis (volume contraction alkalosis)

22
Q

Airway obstruction

A

Respiratory acidosis

23
Q

ARDS

COPD

A

Respiratory acidosis

24
Q

Opiates, sedatives, anesthetics

A

Respiratory acidosis

Inhibition of medullary respiratory center

25
Q

GBS, Polio, ALS, multiple sclerosis

A

Respiratory acidosis

Weakening of respiratory muscles

26
Q

Pneumonia

A

Respiratory alkalosis

Hypoxemia—>increase ventilatory rate

27
Q

Pulmonary embolus

A

Respiratory alkalosis

Hypoxemia—>ventilatory rate

28
Q

High altitude

A

Respiratory alkalosis

Hypoxemia increases ventilatory rate
