Introduction
This guide provides a complete topic coverage breakdown for the NURS 251 Pharmacology Modules
1-4 exam based on the 2026/2027 Portage Learning, ABCnursing, and Geneva College curricula. Module
1 (Foundations – 30% of exam) : Pharmacokinetics (ADME), half-life calculations (5 half-lives for
elimination), steady state (4-5 half-lives), bioavailability, first-pass effect, drug nomenclature (generic vs.
trade names), dosage forms (tablets, capsules, troches, suppositories), routes of administration (oral vs.
parenteral), and FDA drug approval process. Module 2 (Drug Regulation & Safety – 15%) : Pregnancy
categories (A,B,C,D,X), controlled substance schedules (Schedule II highest abuse potential with medical
use), medication error prevention, dose calculations (mg/kg, ml/dose), pharmacogenetics (slow vs. rapid
acetylators in Asian/Hispanic populations). Module 3 (Autonomic Nervous System – 30%) : Adrenergic
agonists (epinephrine, dopamine, dobutamine, norepinephrine), adrenergic antagonists (beta blockers
ending in -lol, alpha blockers ending in -osin), cholinergic agonists (parasympathomimetics, SLUDGE
syndrome), anticholinergics (atropine, oxybutynin – monitor bowel and bladder), CNS drugs
(benzodiazepines for anxiety, phenothiazines for psychosis, opioids with naloxone antidote). Module 4
(Cardiovascular & Endocrine – 25%) : Anticoagulants (heparin/aPTT/protamine, warfarin/INR/vitamin K),
thrombolytics (IV only, bleeding risk), thyroid drugs (levothyroxine, myxedema coma, drug interactions),
diabetes drugs (insulin types, metformin, acarbose, miglitol). Includes test-taking strategies and a 100-
question verified answer bank.
Module 1: Foundations of Pharmacology
Q1. A patient recently started taking a new medication; he mentions to his doctor at
his next appointment that he has noticed his mouth is dry since starting the
medication. He also mentions that this is not a problem, and he has managed it by
increasing the amount of water he is drinking. What drug effect best describes the
dry mouth this patient is experiencing?
A. Adverse Effect
B. Side Effect
C. Toxic Effect
, D. Therapeutic Effect
Rationale: A side effect is a predictable, often unavoidable secondary effect of a drug that
occurs at therapeutic doses. While dry mouth can be bothersome, it is not dangerous in this
context and the patient has managed it without discontinuing the drug. An adverse effect is
more severe and typically requires medical intervention or discontinuation of the drug.
Q2. A patient recently started taking a new medication; he mentions to his doctor at
his next appointment that he has noticed his mouth is extremely dry since starting
the medication to the point where he is not able to eat. He has tried managing it with
lozenges and increased liquids and nothing seems to work. What drug effect best
describes the dry mouth this patient is experiencing?
A. Adverse Effect
B. Side Effect
C. Therapeutic Effect
D. Placebo Effect
Rationale: An adverse effect is a severe, unintended response to a medication that
interferes with daily functioning or quality of life. In this case, the patient cannot eat,
indicating the effect is severe enough to warrant potential drug discontinuation or change.
Adverse effects are more serious than common side effects.
Q3. TRUE/FALSE: Discontinuing drug therapy is always the best course of action
whenever a patient experiences a harmful drug effect.
A. False
Rationale: Discontinuing a medication is not always the best course of action when a
harmful effect occurs. Often, the dose can be adjusted, additional medications can be
added to manage the side effect, or alternative drugs can be tried. The decision must
balance the benefits of treatment against the severity of the harmful effect.
Q4. Which of the following statements is true regarding how pharmacokinetics
changes as a patient ages?
A. Drug metabolism increases, decreasing the duration of the drug
B. Drug metabolism decreases, increasing the duration of the drug
C. Drug absorption increases significantly
, D. Drug distribution remains unchanged with age
Rationale: As patients age, liver function typically declines, leading to decreased drug
metabolism. This results in drugs remaining in the body longer, increasing the duration of
action and potentially requiring dose adjustments to prevent toxicity. Renal function also
decreases with age, further affecting drug elimination.
Q5. TRUE/FALSE: All drugs have both a trade name and a generic name.
A. True
Rationale: Every drug has a generic name (non-proprietary name assigned by the USAN
Council) and at least one trade/brand name (proprietary name assigned by the
manufacturer). For example, acetaminophen is the generic name while Tylenol is a trade
name.
Q6. Select the dosage form that is best described as a flattened tablet that dissolves
in the mouth:
A. Tablet
B. Capsule
C. Troche
D. Suppository
Rationale: A troche (or lozenge) is a flattened tablet designed to dissolve slowly in the
mouth, allowing for local or systemic absorption through the oral mucosa. Tablets are
generally swallowed, capsules contain powder or liquid in a gelatin shell, and suppositories
are inserted into body cavities.
Q7. TRUE/FALSE: Suppositories are designed to melt at body temperature.
A. True
Rationale: Suppositories are formulated with bases (cocoa butter or polyethylene glycol)
that melt or dissolve at body temperature, releasing the medication for local or systemic
absorption. This design ensures the drug becomes available once inserted into the rectum,
vagina, or urethra.
Q8. The two most common routes of administration are oral and parenteral. Which of
the following is a true statement?
A. Oral administration has the fastest onset of action
, B. In general, the onset of action with parenterally administered drugs is fairly
immediate
C. Parenteral administration includes only intravenous routes
D. Oral administration bypasses first-pass metabolism
Rationale: Parenteral administration (intravenous, intramuscular, subcutaneous) bypasses
the gastrointestinal tract and first-pass metabolism, resulting in more immediate onset of
action compared to oral administration. IV administration provides the fastest onset, often
within seconds to minutes.
Q9. The study of how various dosage forms influence the way in which drugs affect
the body describes the term:
A. Pharmacokinetics
B. Pharmacodynamics
C. Pharmaceutics
D. Pharmacotherapeutics
Rationale: Pharmaceutics is the science of dosage form design—how the physical and
chemical properties of a drug and its formulation affect its release, absorption, and overall
therapeutic effect. It bridges the gap between drug manufacturing and drug action.
Q10. TRUE/FALSE: Pharmacokinetics can also be thought of as what the body does
to a drug.
A. True
Rationale: Pharmacokinetics is the study of drug movement through the body and includes
four processes: absorption, distribution, metabolism, and excretion (ADME). It literally
means "what the body does to the drug," while pharmacodynamics means "what the drug
does to the body."
Q11. How many half-lives does it take for most drugs to be effectively removed from
the body?
A. 2
B. 3
C. 4
