Practice, Detailed Rationales & Complete
Question 1
The primary care NP is reviewing a patient's nutritional intake and lab work, which
reflects hypoalbuminemia. This is critical to understand because hypoalbuminemia
will most likely cause which of the following?
A) Increased drug metabolism in the liver
B) Decreased renal excretion of medications
C) Increased free drug concentration due to decreased protein binding
D) Enhanced first-pass effect in the gastrointestinal tract
Correct ,,,answer,,,: C
Rationale: Hypoalbuminemia reduces available protein-binding sites, leading to an
increase in the unbound (free) fraction of highly protein-bound drugs. This increases
,the pharmacologically active drug concentration, potentially leading to toxicity even
at standard doses. Albumin is the primary protein for drug binding in the plasma.
Question 2
A patient with liver cirrhosis is prescribed a medication with high first-pass
metabolism. The nurse expects:
A) Increased bioavailability
B) Decreased drug half-life
C) Reduced risk of toxicity
D) Enhanced protein binding
Correct ,,,answer,,,: A
Rationale: High first-pass metabolism occurs in the liver. Cirrhosis impairs hepatic
function, reducing first-pass extraction, thereby increasing oral bioavailability and
risk of toxicity. The drug reaches systemic circulation in higher concentrations than
expected.
Question 3
A drug with a half-life of 12 hours is administered intravenously. Approximately how
many hours until steady state is reached?
A) 24 hours
B) 36 hours
C) 60 hours
D) 120 hours
,Correct ,,,answer,,,: C
Rationale: Steady state is achieved after 4–5 half-lives. 5 × 12 = 60 hours. At
steady state, the rate of drug administration equals the rate of drug elimination, and
plasma concentrations remain relatively constant.
Question 4
Which pharmacokinetic process is primarily responsible for drug elimination?
A) Absorption
B) Distribution
C) Metabolism
D) Excretion
Correct ,,,answer,,,: D
Rationale: Excretion (renal, biliary, pulmonary) removes active drug from the body.
Metabolism inactivates drugs but is not the final elimination step. Both metabolism
and excretion contribute to drug clearance.
Question 5
A patient with chronic kidney disease (CKD) has a decreased glomerular filtration
rate (GFR). The nurse should anticipate:
A) Increased drug half-life and risk of accumulation
B) Decreased drug half-life
C) Enhanced drug metabolism
D) Increased protein binding
, Correct ,,,answer,,,: A
Rationale: Decreased GFR reduces renal clearance of medications, prolonging
half-life and increasing the risk of drug accumulation and toxicity. Dosage
adjustments are often required for renally eliminated drugs.
Question 6
A drug that is a weak acid (pKa 4.4) is administered orally. In the stomach (pH 1.4),
the drug will be mostly:
A) Non-ionized and readily absorbed
B) Ionized and poorly absorbed
C) Trapped in the stomach
D) Bound to albumin
Correct ,,,answer,,,: A
Rationale: Weak acids are non-ionized at low pH (pH < pKa), favoring passive
diffusion across gastric mucosa. Non-ionized drugs are lipid-soluble and readily
cross cell membranes.
Question 7
Phase II metabolism typically involves:
A) Oxidation via CYP-450
B) Reduction reactions
C) Conjugation (e.g., glucuronidation)
D) Hydrolysis
