,Q1. A drug with a volume of distribution of 40 L is administered as a continuous IV
infusion at a rate of 10 mg/h. If the drug is eliminated by first-order kinetics with a
half-life of 4 hours, what is the approximate steady-state concentration (mg/L)?
A. 0.25
B. 0.5
C. 1.0
D. 2.0
Correct Answer: C. 1.0
Rationale: At steady state, infusion rate = clearance × concentration. Clearance = 0.693 ×
Vd / half-life = 0.693 × = 6.93 L/h. Thus, concentration = .93 1.44 mg/L,
closest to 1.0. Other options are miscalculations.
Why Wrong:
A - This value would result from using Vd incorrectly as clearance.
B - This would be the concentration if half-life were 8 hours.
D - This would be obtained if clearance were 5 L/h, an underestimation.

Q2. Which receptor type, when activated, directly modulates gene transcription and
produces effects that typically take hours to days to manifest?
A. Ligand-gated ion channels
B. G protein-coupled receptors
C. Intracellular receptors
D. Enzyme-linked receptors
Correct Answer: C. Intracellular receptors
Rationale: Intracellular receptors (e.g., steroid hormone receptors) bind lipid-soluble
ligands, translocate to the nucleus, and alter gene expression, leading to delayed
responses. The other receptor types mediate rapid effects via ion flux, second messengers,
or kinase cascades.
Why Wrong:
A - Ligand-gated ion channels produce milliseconds-fast effects.
B - GPCRs act within seconds to minutes via second messengers.
D - Enzyme-linked receptors act via phosphorylation cascades in minutes.
Reference: Lehne, R.A. (2026). Pharmacology for Nursing Care, 12th Ed., Ch. 3
Q3. A patient on a stable dose of warfarin is prescribed metronidazole for an
anaerobic infection. Two days later, the INR is markedly elevated. Which mechanism
best explains this interaction?
A. Displacement of warfarin from plasma albumin
Page 3
, B. Inhibition of CYP2C9, reducing warfarin metabolism
C. Induction of CYP3A4, increasing warfarin clearance
D. Antagonism of vitamin K at the epoxide reductase enzyme
Correct Answer: B. Inhibition of CYP2C9, reducing warfarin metabolism
Rationale: Metronidazole inhibits CYP2C9, the primary enzyme that metabolizes the
S-enantiomer of warfarin, leading to increased warfarin levels and INR. Displacement (A)
is transient and not the main mechanism; induction (C) would decrease INR;
metronidazole does not directly antagonize vitamin K (D).
Why Wrong:
A - Protein binding displacement is transient and rarely causes sustained INR
elevation.
C - CYP3A4 induction would increase warfarin metabolism, lowering INR.
D - Warfarin itself inhibits VKORC1; metronidazole does not.
Reference: Lehne, R.A. (2026). Pharmacology for Nursing Care, 12th Ed., Ch. 70
Q4. Which pharmacodynamic principle explains why a partial agonist at a receptor
can act as an antagonist when a full agonist is present?
A. It has higher affinity but lower intrinsic efficacy than the full agonist.
B. It has lower affinity but higher intrinsic efficacy than the full agonist.
C. It binds to an allosteric site, changing receptor conformation.
D. It downregulates receptor number, reducing the full agonist's effect.
Correct Answer: A. It has higher affinity but lower intrinsic efficacy than the full
agonist.
Rationale: A partial agonist has high affinity for the receptor but lower intrinsic efficacy
(maximal response). When a full agonist is present, the partial agonist competes for the
same binding site, reducing the full agonist's effect. This is the basis of its antagonist
action.
Why Wrong:
B - Lower affinity would not effectively compete with the full agonist.
C - Allosteric modulation is not the primary mechanism for partial agonism.
D - Downregulation is a chronic adaptation, not the immediate competitive effect.
Reference: Lehne, R.A. (2026). Pharmacology for Nursing Care, 12th Ed., Ch. 2
Q5. A patient with type 2 diabetes is started on metformin. Which statement best
describes its primary mechanism of action?
A. Increases pancreatic insulin secretion by blocking K-ATP channels
B. Decreases hepatic glucose production and increases peripheral insulin sensitivity
C. Slows carbohydrate absorption by inhibiting alpha-glucosidase enzymes
D. Activates PPAR-gamma receptors in adipose tissue to improve glucose uptake
