,Q1. A patient with chronic kidney disease is prescribed a medication that undergoes
significant renal excretion. Which term best describes the process by which the drug
is filtered from the blood into the renal tubule?
A. Tubular reabsorption
B. Glomerular filtration
C. Tubular secretion
D. First-pass metabolism
Correct Answer: B. Glomerular filtration
Rationale: Glomerular filtration is the passive movement of water and solutes from the
glomerular capillaries into Bowman's capsule, driven by hydrostatic pressure. Tubular
reabsorption moves substances from the tubule back into the blood, while tubular
secretion actively transports drugs from the blood into the tubule. First-pass metabolism
occurs in the liver, not the kidney.
Why Wrong:
A - Reabsorption moves substances from the tubule back into the blood, not out of it.
C - Secretion is an active transport process that moves drugs from the blood into the
tubule, but it is not the initial filtration step.
D - First-pass metabolism is hepatic, not renal.
Reference: Lehne, R.A. (2026). Pharmacology for Nursing Care, 12th Ed., Ch. 4
Q2. Which of the following best explains why a drug with a high volume of
distribution (Vd) may have a prolonged half-life?
A. High Vd indicates extensive plasma protein binding, slowing hepatic metabolism.
B. High Vd means the drug is rapidly excreted by the kidneys, reducing its half-life.
C. High Vd suggests extensive tissue binding, reducing plasma concentration and
slowing elimination.
D. High Vd is associated with increased first-pass metabolism, decreasing
bioavailability.
Correct Answer: C. High Vd suggests extensive tissue binding, reducing plasma
concentration and slowing elimination.
Rationale: A high Vd indicates the drug is widely distributed into tissues, leaving lower
plasma concentrations. Since elimination processes (hepatic/renal) act on the plasma
concentration, a lower plasma level slows the rate of elimination, prolonging the half-life.
Plasma protein binding does not directly determine Vd; rapid excretion would shorten
half-life; first-pass metabolism relates to bioavailability, not Vd.
Why Wrong:
A - Protein binding affects distribution, but high Vd is more about tissue binding than
protein binding.
B - Rapid renal excretion would decrease Vd and shorten half-life, not prolong it.

, D - First-pass metabolism reduces bioavailability, not Vd.

Q3. A drug is a weak acid with a pKa of 4.4. In the stomach (pH 2), what is the
predominant state of the drug, and how will it behave?
A. Ionized, poorly absorbed
B. Non-ionized, well absorbed
C. Ionized, well absorbed
D. Non-ionized, poorly absorbed
Correct Answer: B. Non-ionized, well absorbed
Rationale: For a weak acid, when the pH is below the pKa, the drug exists predominantly
in the non-ionized (uncharged) form. Non-ionized drugs are lipophilic and readily cross
cell membranes, so absorption is enhanced in the acidic stomach. Ionized forms are
hydrophilic and poorly absorbed.
Why Wrong:
A - Ionized form predominates when pH > pKa, not below.
C - Ionized drugs are poorly absorbed due to low lipophilicity.
D - Non-ionized form is well absorbed, not poorly.
Reference: Lehne, R.A. (2026). Pharmacology for Nursing Care, 12th Ed., Ch. 4
Q4. Which of the following best describes the mechanism of action of
non-depolarizing neuromuscular blocking agents (e.g., rocuronium)?
A. They bind to acetylcholine receptors and cause prolonged depolarization of the
motor end plate.
B. They competitively block acetylcholine at the nicotinic receptor, preventing
depolarization.
C. They inhibit acetylcholinesterase, increasing acetylcholine at the neuromuscular
junction.
D. They act centrally to enhance GABA-mediated inhibition in the spinal cord.
Correct Answer: B. They competitively block acetylcholine at the nicotinic receptor,
preventing depolarization.
Rationale: Non-depolarizing neuromuscular blockers are competitive antagonists at
nicotinic acetylcholine receptors on the motor end plate. They prevent acetylcholine from
binding, thereby blocking depolarization and muscle contraction. Succinylcholine is a
depolarizing agent that causes prolonged depolarization; acetylcholinesterase inhibitors
reverse non-depolarizing blockade; GABAergic agents are not involved.
Why Wrong:
A - This describes depolarizing agents like succinylcholine.
C - Acetylcholinesterase inhibitors increase ACh, which would reverse blockade, not
