Drugs do not metabolize the same way in all people. For what patient would a nurse expect to assess for an alteration in drug metabolism?
- A. A 35-year-old woman with cervical cancer
- B. A 41-year-old man with kidney stones
- C. A 50-year-old man with cirrhosis of the liver
- D. A 62-year-old woman in acute renal failure
Correct Answer: C
Rationale: The liver is the most important site of drug metabolism. If the liver is not functioning effectively, as in patients with cirrhosis, drugs will not metabolize normally so that toxic levels could develop unless dosage is reduced. A patient with cervical cancer or kidney stones would not be expected to have altered ability to metabolize drugs so long as no liver damage existed. The patient with renal failure would have altered excretion of the drugs through the renal system but metabolism would not be impacted.
