Answer to Question 1
Correct Answer: 1,2
Rationale 1: Increased gastric pH may enhance the absorption of acidlabile drugs such as ampicillin and penicillin and slow the absorption of weak acids such as Phenobarbital.
Rationale 2: Delayed gastric emptying may keep a drug in the stomach longer, increasing the absorption across the stomach mucosa but slowing the rate of drug absorption for drugs designed to be absorbed in the intestine.
Rationale 3: The immature hepatic cytochrome P450 enzyme system affects metabolism of drugs, not absorption.
Rationale 4: The immaturity of the kidneys affects excretion of drugs, not absorption.
Rationale 5: The high water-to-fat proportion affects distribution of drugs, not absorption.
