Answer to Question 1

ANS: A
Renal excretion of K+ is controlled by aldosterone levels. Aldosterone inhibits the enzyme re-sponsible for K+ transport in the distal renal tubular cells of the kidney. Metabolic acidosis also inhibits the transport system.

Answer to Question 2

ANS: D
HCO3 plays an important role in acid-base homeostasis and is the strong base in the bicar-bonate-carbonic acid buffer pair. HCO3 is the primary means for transporting carbon dioxide from the tissues to the lungs. The ratio of HCO3 to carbonic acid in healthy individuals is main-tained near 20:1.

The use of salicylates dates back 2,500 years to Hippocrates’s recommendation of willow bark (from which a salicylate is derived) as an aid to the pains of childbirth. However, overdosage of salicylates can harm body fluids, electrolytes, the CNS, the GI tract, the ears, the lungs, the blood, the liver, and the kidneys and cause coma or death.

Drug abusers experience the following scenario: The pleasure given by their drug (or drugs) of choice is so strong that it is difficult to eradicate even after years of staying away from the substances involved. Certain triggers may cause a drug abuser to relapse. Research shows that long-term drug abuse results in significant changes in brain function that persist long after an individual stops using drugs. It is most important to realize that the same is true of not just illegal substances but alcohol and tobacco as well.
