Which aspect of pharmacokinetics should the nurse be most concerned with when caring for a patient with abnormal functioning of hepatic enzymes?

The correct answer is D: Metabolism. When hepatic enzymes are abnormal, it affects the liver's ability to metabolize drugs. This can lead to drug toxicity or reduced drug effectiveness. The nurse should closely monitor drug dosages and frequency to prevent adverse effects. Absorption (A) may be affected by liver dysfunction but is less critical than metabolism in this scenario. Distribution (B) and Excretion (C) are more related to renal function than hepatic enzymes. The other choices (E, F, G) are not applicable. In summary, impaired hepatic metabolism can significantly alter drug response, making it the primary concern for the nurse.
