Acid Base

Question 1

If you have a metabolic acidosis, what is the next thing you look at?

Answer 1

Anion Gap

Question 2

Next step in a metabolic alkalosis?

Answer 2

Urine Chloride (or give volume and reasses)

Question 3

Next Step in NON anion gap metabolic acidosis?

Answer 3

Urine Anion Gap

Question 4

What are the causes of Respiratory Acidosis?

Answer 4

Hypoventilation = opiates, Asthma/COPD, OSA

Question 5

What are the causes of Respiratory Alkalosis?

Answer 5

Hyperventilation Pain, Anxiety, Hypoxemia

Question 6

What is you differential for Anion Gap Metabolic Acidosis?

Answer 6

MUDPILES Methanol, Uremia, DKA, Propylene Glycol, Isopropanol (Isoniazid), Lactate, Ethylene Glycol, Salicylates.

Question 7

Why does a urine chloride matter?

Answer 7

The urine chloride is an indirect measure of aldosterone, aldosterone sucks up Na and Cl. If there is low urine chloride, the metabolic alkalosis is volume responsive.
