Which statement about food and drug interactions is true?

Patient preference is the food and drug interaction of most concern.

Foods alter drug absorption and metabolism but not drug action.

Some foods, such as grapefruit, can interact with CYP isoenzymes and alter drug metabolism.

All medications are best absorbed with food.

Answer and Explanation

The Correct Answer is C

Choice A reason: Patient preference is not a primary concern in food-drug interactions; physiological effects are. Grapefruit’s impact on metabolism is significant, so this is incorrect for the true statement.

Choice B reason: Foods can alter absorption and metabolism, but some also affect drug action (e.g., tyramine with MAOIs). This statement is incomplete, making it incorrect compared to grapefruit’s specific effect.

Choice C reason: Grapefruit inhibits CYP isoenzymes, altering drug metabolism and increasing drug levels. This is a well-documented interaction, making it the correct true statement about food-drug interactions.

Choice D reason: Not all medications are best absorbed with food; some require empty stomachs. Grapefruit’s metabolic interaction is more accurate, so this is incorrect for the true statement.

Correct Answer is B

Explanation

Choice A reason: Metabolic acidosis involves low pH (<7.35) and low HCO3- (<22 mEq/L). Here, pH is 7.48 (alkalotic) and HCO3- is 29 mEq/L (high), indicating alkalosis, not acidosis. PaCO2 (44 mm Hg) is normal, ruling out respiratory causes, making this choice incorrect.

Choice B reason: pH 7.48 (high), PaCO2 44 mm Hg (normal), and HCO3- 29 mEq/L (high) indicate metabolic alkalosis, likely from conditions like vomiting or diuretic use, increasing bicarbonate. No respiratory compensation (normal PaCO2) confirms uncompensated metabolic alkalosis, making this the correct choice.

Choice C reason: Respiratory acidosis requires high PaCO2 (>45 mm Hg) and low pH. Here, PaCO2 is 44 mm Hg (normal) and pH is 7.48 (alkalotic), with high HCO3-, pointing to a metabolic cause, not respiratory, making this choice incorrect for the ABG values.

Choice D reason: Respiratory alkalosis involves low PaCO2 (<35 mm Hg) and high pH. With PaCO2 at 44 mm Hg (normal) and high HCO3- (29 mEq/L), the alkalosis is metabolic, not respiratory. This choice doesn’t match the ABG profile, making it incorrect.

A. It directly activates receptors to affect a specific physiologic process. B. It prevents receptor activation to affect a specific physiologic process. C. It directly activates receptors to affect many physiologic processes. D. It prevents receptor activation to affect many physiologic processes.

Correct Answer is C

Explanation

Choice A reason: Nonselective agonists activate multiple receptors, not specific ones, leading to widespread effects. Specific processes are targeted by selective agonists, so this is incorrect for nonselective drugs.

Choice B reason: Nonselective agonists activate, not prevent, receptors. Prevention is the role of antagonists, so this is incorrect for a nonselective agonist’s mechanism of action.

Choice C reason: Nonselective agonists activate multiple receptor types, affecting many physiologic processes (e.g., epinephrine). This broad action is their hallmark, making it the correct choice for the drug’s effect.

Choice D reason: Preventing receptor activation describes antagonists, not agonists. Nonselective agonists stimulate multiple processes, so this is incorrect for the drug’s pharmacological action.
