Answer to Question 1

ANS: D
Calcium is present in the blood in the following three forms: ionized, protein bound, and com-plex. Approximately 50 of serum calcium is ionized (Ca2+) and is physiologically active. An additional 10 forms calcium anion complexes. The remaining 40 is bound to plasma proteins, primarily albumen. Ionized calcium is physiologically active in processes such as enzyme activity, blood clotting, neuromuscular irritability, and bone calcification. Acidemia increases, and alkale-mia decreases, the concentration of Ca2+ in the serum.

Answer to Question 2

ANS: C
Hyperkalemia (elevated serum potassium) is most common in renal insufficiency.

When Gabriel Fahrenheit invented the first mercury thermometer, he called "zero degrees" the lowest temperature he was able to attain with a mixture of ice and salt.
