Often prescribed with levodopa/carbidopa in the treatment of
Parkinson's Disease -ANSWER-Bromocriptine
What medication may cause serious or possibly life-threatening sleep
behaviors, such as sleep driving? -ANSWER-Ambien
A 76-year-old patient with hypoalbuminemia is prescribed a highly
protein-bound medication. The patient's renal function is unchanged,
but signs of medication toxicity develop shortly after therapy begins.
Which pharmacokinetic change best explains this finding?
A. Increased first-pass metabolism
B. Decreased free-drug concentration
C. Increased free-drug concentration caused by reduced protein binding
D. Increased renal clearance
Answer: C. Increased free-drug concentration caused by reduced
protein binding
,Rationale: Reduced albumin increases the unbound fraction of highly
protein-bound drugs. Because the unbound fraction is
pharmacologically active, toxicity may occur even when the total serum
concentration appears acceptable.*
A patient taking a medication metabolized primarily by CYP3A4 begins
taking a potent CYP3A4 inhibitor. What effect should the nurse
anticipate?
A. Decreased plasma concentration of the medication
B. Increased metabolism and shorter half-life
C. Increased plasma concentration and possible toxicity
D. Immediate renal elimination of the medication
Answer: C. Increased plasma concentration and possible toxicity
Rationale: CYP inhibition decreases hepatic metabolism of susceptible
drugs, potentially increasing serum concentrations and adverse
effects.*
A patient asks why a medication prescribed orally may require a higher
dose than the same medication administered intravenously. Which
explanation is most accurate?
,A. Oral medications are always less potent
B. Oral medications may undergo first-pass metabolism before reaching
systemic circulation
C. Intravenous medications are always protein bound
D. Oral medications cannot enter the bloodstream
Answer: B. Oral medications may undergo first-pass metabolism before
reaching systemic circulation
Rationale: Drugs absorbed from the gastrointestinal tract may pass
through the liver before reaching systemic circulation, reducing
bioavailability.*
A medication has a half-life of 12 hours. Approximately how long will it
generally take to reach near steady-state concentrations after repeated
dosing?
A. 6 hours
B. 12 hours
C. 24 hours
D. 48–60 hours
Answer: D. 48–60 hours
, Rationale: Most medications approach steady state after approximately
four to five half-lives. For a 12-hour half-life, this is approximately 48–
60 hours.*
A patient with significant renal impairment is prescribed a medication
primarily eliminated unchanged by the kidneys. Which pharmacokinetic
consequence is most concerning?
A. Accelerated elimination
B. Drug accumulation and toxicity
C. Increased first-pass metabolism
D. Reduced drug exposure
Answer: B. Drug accumulation and toxicity
Rationale: Reduced renal clearance can prolong the drug's half-life and
cause accumulation unless the dose or dosing interval is appropriately
adjusted.*
A patient taking warfarin asks whether they should completely
eliminate spinach and other vitamin-K-containing foods. Which
response is most appropriate?
A. "Yes, vitamin K should be completely avoided."
B. "Increase vitamin K substantially while taking warfarin."
C. "Maintain a relatively consistent intake of vitamin K-containing
foods."
D. "Vitamin K has no effect on warfarin."
