Answer to Question 1

Correct Answer: 1
Rationale: Grapefruit juice lowers the acidity of enzymes in the GI system that break down medications. This in turn results in higher medication absorption into the bloodstream. A reduction in citrus fruit intake would likely cause a lowered drug reaction. A reduced intake of alcohol or fiber would not likely produce an increased reaction to a drug. (p. 20)
