(Select All that Apply.).
Blood flow of the mucous lining of the stomach and intestines.
Drug distribution.
Enzyme activity.
Gastric pH.
Gastric emptying time.
Correct Answer : A,C,D,E
Choice A rationale:
The blood flow of the mucous lining of the stomach and intestines can affect how quickly a drug is absorbed.
Choice B rationale:
Drug distribution refers to how a drug spreads throughout the body, not its absorption in the gastrointestinal tract.
Choice C rationale:
Enzyme activity can affect how a drug is metabolized and absorbed.
Choice D rationale:
Gastric pH can affect drug absorption as some drugs are better absorbed in an acidic environment, while others are better absorbed in an alkaline environment.
Choice E rationale:
Gastric emptying time can affect drug absorption. Drugs may stay in contact with the absorptive tissue longer if the gastric emptying time is slower, allowing for increased absorption.

Correct Answer is A
Explanation
Choice A rationale:
A decrease in blood pressure is a common side effect when a medication increases urine output, as the reduction in fluid volume can lead to lower blood pressure.
Choice B rationale:
While a decrease in blood pressure might be desired in certain conditions (like hypertension), in this context it is a side effect, not the primary desired effect.
Choice C rationale:
The therapeutic effect of the medication in this case is to increase urine output, not to decrease blood pressure.
Correct Answer is ["7"]
Explanation
The correct answer is 7 mL. Step 1 is to calculate the concentration of amoxicillin in mg/mL: 250 mg ÷ 5 mL = 50 mg/mL.
Step 2 is to use the calculated concentration to find the volume: Volume (mL) = 350 mg ÷ 50 mg/mL = 7 mL.
