Answer to Question 1

A
Wide, M-shaped P waves are seen in left atrial hypertrophy and are called P mitrale because left atrial hypertrophy is often caused by mitral stenosis.

Answer to Question 2

D
Acid ketones dissociate and yield hydrogen ions (H+) that accumulate and precipitate a fall in serum pH. The level of serum bicarbonate also decreases consistent with a diagnosis of metabolic acidosis. Breathing becomes deep and rapid (Kussmaul respirations) to release carbonic acid in the form of carbon dioxide. Acetone is exhaled, giving the breath its characteristic fruity odor.
