ULTIMATE PHARMACOLOGY TEST BANK
LILLEY’S CANADIAN HEALTH CARE
PRACTICE 5TH EDITION (CHAPTERS 1-58)
This comprehensive test bank is meticulously aligned with
Lilley’s Pharmacology for Canadian Health Care Practice (5th
Edition). It features verified multiple-choice questions complete
with accurate answers and detailed clinical rationales highlighting
Canadian nursing standards, pharmacokinetics, and safe drug
administration. It is the ultimate high-yield study companion
engineered to help nursing students ace their pharmacology
exams and master complex dosage calculations.
Part 1: Nursing Process, Pharmacokinetics, &
Safety (Questions 1–15)
1. A nurse is reviewing a patient's electronic health
record prior to administering a new cardiac
medication. Which phase of the nursing process
is the nurse performing?
a) Assessment
b) Planning
c) Implementation
d) Evaluation
Answer: a)
Rationale: Assessment involves gathering
data, reviewing records, and establishing a
baseline before any clinical intervention.
,2. An 82-year-old patient is prescribed a lipid-
soluble medication. The nurse understands that
age-related physiological changes affect
distribution. Which factor must the nurse
consider?
a) Increased total body water
b) Increased percentage of body fat
c) Increased serum albumin levels
d) Enhanced hepatic blood flow
Answer: b)
Rationale: Older adults experience a relative
increase in body fat percentage, which
causes lipid-soluble drugs to distribute more
widely and prolongs their half-life.
3. A patient receives an intravenous (IV) dose of
an antibiotic. The nurse knows that the
bioavailability of a drug administered via the
intravenous route is always which percentage?
a) 50%
b) 75%
c) 100%
d) Variable based on gastric pH
Answer: c)
Rationale: Intravenous administration
bypasses the first-pass effect of the liver
, entirely, providing immediate 100%
bioavailability in the systemic circulation.
4. During a medication reconciliation, a patient
states they take an over-the-counter herbal
supplement to improve mood. The nurse
identifies this as St. John's wort and recognizes
it poses a risk because of which mechanism?
a) It decreases renal blood flow.
b) It is a potent hepatic enzyme inducer.
c) It neutralizes gastric acidity.
d) It acts as a heavy metal chelator.
Answer: b)
Rationale: St. John's wort induces
cytochrome P450 hepatic enzymes, which
accelerates the metabolism of many
prescription medications, reducing their
therapeutic efficacy.
5. A nurse is preparing to administer a medication
that has a narrow therapeutic index. What
monitoring strategy is most critical for ensuring
patient safety?
a) Checking the patient's daily fluid intake and
output
b) Monitoring serum drug peak and trough levels
c) Assessing the patient's skin integrity hourly
, d) Performing a baseline cognitive assessment
Answer: b)
Rationale: Medications with a narrow
therapeutic index have a small margin of
safety between therapeutic and toxic doses;
serum level monitoring is required to prevent
toxicity.
6. A pediatric patient is prescribed a weight-based
dose of an anticonvulsant. Why are infants and
young children at an increased risk for drug
toxicity compared to adults?
a) They have faster glomerular filtration rates.
b) Their gastric environment is highly acidic.
c) They have immature hepatic enzyme
systems.
d) They have lower body surface area ratios.
Answer: c)
Rationale: Immature liver enzymes in infants
reduce their ability to metabolize
medications efficiently, leading to prolonged
drug activity and higher risks of toxicity.
7. While reviewing a medication order, a Canadian
nurse notes that a drug dosage is written as ".5
mg". What is the correct nursing action to
prevent a medication error?
