A nurse is giving an enteral medication. The patient asks why this method is preferable for this drug. How will the nurse reply?
This route allows more rapid absorption of the drug
This route prevents inactivation of the drug by digestive enzymes
This route is the best way to control serum drug levels
This route is safer, less expensive, and more convenient
The Correct Answer is D
Choice A reason: Enteral (oral) administration typically has slower absorption than intravenous routes due to first-pass metabolism in the liver and variable gastric emptying. While effective for many drugs, it’s not faster than parenteral routes, making this choice incorrect for describing the primary advantage of enteral administration.
Choice B reason: Some enteral drugs are inactivated by digestive enzymes or liver metabolism (first-pass effect), not prevented. Special formulations (e.g., enteric-coated) may protect drugs, but this isn’t a general advantage of the enteral route, which often faces enzymatic degradation, making this choice inaccurate.
Choice C reason: Enteral administration does not offer superior control of serum drug levels compared to intravenous routes, which provide precise dosing and immediate bioavailability. Oral drugs face variable absorption and first-pass metabolism, leading to less predictable levels, making this choice incorrect for enteral benefits.
Choice D reason: Enteral administration is safer (avoids injection risks like infection), less expensive (no need for sterile equipment), and more convenient (self-administered at home). These advantages make it preferable for many drugs, aligning with patient compliance and cost-effectiveness, making this the correct choice for the nurse’s response.

Correct Answer is B
Explanation
Choice A reason: Glucuronidation does not primarily involve fecal excretion; it conjugates drugs for urinary excretion. Hydrolysis is unrelated, and fecal routes are secondary, so this is incorrect for glucuronidation’s role.
Choice B reason: Glucuronidation conjugates drugs, making them water-soluble for transport across renal tubules and excretion in urine. This is the primary mechanism, making it the correct choice for drug elimination.
Choice C reason: Enterohepatic recirculation involves some drugs, but glucuronidation aims for excretion, not recycling. Prolonging drug presence is not the goal, so this is incorrect for the process.
Choice D reason: Glucuronidation facilitates excretion, not reabsorption. Reabsorbing drugs would counteract its purpose of eliminating metabolites, making this incorrect compared to urinary excretion.
Correct Answer is B
Explanation
Choice A reason: Metabolic acidosis involves low pH and HCO3-; here, pH is normal, and HCO3- is high. Elevated PaCO2 compensates for high HCO3-, so this is incorrect for the ABG values.
Choice B reason: Normal pH (7.39), high HCO3- (29), and high PaCO2 (47) indicate metabolic alkalosis fully compensated by respiratory retention of CO2. This matches the values, making it correct.
Choice C reason: Respiratory alkalosis has low PaCO2 and normal or low HCO3-. Here, PaCO2 and HCO3- are high, ruling this out, so it’s incorrect for the given ABG profile.
Choice D reason: Respiratory acidosis has high PaCO2 and low pH. Normal pH and high HCO3- suggest metabolic alkalosis, not respiratory acidosis, making this incorrect for the values.
