PrepTest 34, Section 2, Question 19
People should avoid taking the antacid calcium carbonate in doses larger than half a gram, for despite its capacity to neutralize stomach acids, calcium carbonate can increase the calcium level in the blood and thus impair kidney function. Moreover, just half a gram of it can stimulate the production of gastrin, a stomach hormone that triggers acid secretion.

Which one of the following is most strongly supported by the information above?
Cessation of gastrin production is a more effective method of controlling excess stomach acid than is direct neutralization of stomach acid.
People who avoid taking more than half a gram of calcium carbonate are less likely than average to suffer from impaired kidney function.
Doses of calcium carbonate smaller than half a gram can reduce stomach acid more effectively than much larger doses do.
Half a gram of calcium carbonate can causally contribute to both the secretion and the neutralization of stomach acids.
Impaired kidney function may increase the level of calcium in the blood.
