Answer to Question 1

ANS: D
Monoamine oxidase inhibitors are not shown to have any interaction with grapefruit juice; therefore, further education is needed for this patient.
Calcium channel blockers should not be taken with grapefruit or grapefruit juice because of increased effects that may occur with the medication; no further education is required.
HMG-CoA reductase inhibitors should not be taken with grapefruit or grapefruit juice because of increased effects that may occur with medication; no further education is required.
Caffeine should not be taken with grapefruit or grapefruit juice because increased CNS stimulation may occur from the interaction; no further education is required.

Answer to Question 2

ANS: D
Eye drops do bind with receptors for a desired effect; they therefore are not receptorless, and the learner needs further instruction.
Antiseptics, saline laxatives, and chelating agents all are receptorless drugs.
