• Medication administration and dosage principles
• Autonomic nervous system and cardiovascular pharmacology
• Endocrine and metabolic pharmacology
• Antimicrobial and anti-infective therapy
• Central nervous system and psychiatric pharmacology
• Analgesics, anti-inflammatory agents, and musculoskeletal medications
• Respiratory and gastrointestinal pharmacology
• Medication safety, adverse effects, interactions, and patient education
* INTRODUCTION *
This comprehensive NURS 615 PHARM assessment is designed to strengthen the knowledge
and clinical reasoning required for safe, effective medication therapy. The questions assess
pharmacologic principles, drug mechanisms, therapeutic uses, adverse effects,
contraindications, interactions, medication administration, monitoring, patient education,
and professional nursing responsibilities. Multiple-choice questions are used to develop
recognition, interpretation, application, and clinical decision-making skills. Emphasis is
placed on understanding why medications produce particular effects and how nurses identify
therapeutic responses, toxicity, and medication-related risks. Scenario-based questions
encourage practical application of pharmacology principles and preparation for
examination-style questions requiring careful distinction among similar medications, adverse
effects, and interventions.
PHARMACOLOGIC FOUNDATIONS
Question 1. Which statement best describes pharmacokinetics?
A. The effects a drug produces on its target tissues
B. The movement of a drug through absorption, distribution, metabolism, and excretion
C. The interaction between two medications at a receptor
D. The relationship between drug dosage and therapeutic response
Correct Answer: B. The movement of a drug through absorption, distribution, metabolism,
and excretion
,Explanation: Pharmacokinetics describes what the body does to a drug through the
processes of absorption, distribution, metabolism, and excretion. Pharmacodynamics
primarily describes what the drug does to the body.
Question 2. Which pharmacokinetic process involves movement of a medication from the
administration site into the systemic circulation?
A. Absorption
B. Distribution
C. Metabolism
D. Excretion
Correct Answer: A. Absorption
Explanation: Absorption is the movement of a drug from its administration site into the
bloodstream. Route of administration, blood flow, formulation, and gastrointestinal function
can affect absorption.
Question 3. A medication administered intravenously has which characteristic compared
with an orally administered medication?
A. It must undergo extensive first-pass metabolism
B. Its absorption is delayed by gastrointestinal motility
C. It enters systemic circulation without requiring an absorption step
D. Its bioavailability is always less than 50%
Correct Answer: C. It enters systemic circulation without requiring an absorption step
Explanation: Intravenous medications are delivered directly into the bloodstream, giving
them essentially complete systemic bioavailability and bypassing gastrointestinal absorption
and first-pass hepatic metabolism.
Question 4. Which organ is primarily responsible for metabolism of many medications?
A. Heart
B. Liver
C. Spleen
D. Pancreas
Correct Answer: B. Liver
,Explanation: The liver is the principal organ involved in drug metabolism. Hepatic enzymes,
particularly cytochrome P450 enzymes, modify many medications to facilitate their
elimination.
Question 5. Which organ is the major route of elimination for many water-soluble drugs and
metabolites?
A. Kidneys
B. Lungs
C. Skin
D. Stomach
Correct Answer: A. Kidneys
Explanation: The kidneys eliminate many medications and metabolites through urine. Renal
impairment can therefore increase drug accumulation and toxicity for medications primarily
eliminated renally.
Question 6. What is meant by a medication's half-life?
A. Time required for a medication to begin working
B. Time required for the medication to reach peak concentration
C. Time required for half of the drug amount in the body to be eliminated
D. Time required for complete absorption of a medication
Correct Answer: C. Time required for half of the drug amount in the body to be eliminated
Explanation: Half-life is the time required for the amount or plasma concentration of a drug
to decrease by approximately 50%. It helps determine dosing intervals and the time required
to reach steady state or eliminate a drug.
Question 7. A nurse administers a medication with a narrow therapeutic index. What is the
most important implication?
A. The medication has no serious adverse effects
B. Small differences between therapeutic and toxic concentrations require careful
monitoring
C. The medication can be administered without laboratory monitoring
D. The medication is always available over the counter
Correct Answer: B. Small differences between therapeutic and toxic concentrations require
careful monitoring
, Explanation: A narrow therapeutic index means the therapeutic concentration is relatively
close to the toxic concentration. Medications such as certain antiarrhythmics and
anticonvulsants therefore require careful dosing and monitoring.
Question 8. Which term describes the fraction of an administered drug dose that reaches
systemic circulation unchanged?
A. Potency
B. Efficacy
C. Bioavailability
D. Clearance
Correct Answer: C. Bioavailability
Explanation: Bioavailability represents the proportion of an administered dose that reaches
systemic circulation in an unchanged form. Intravenous administration generally provides
complete systemic bioavailability.
Question 9. Which medication route generally produces the most rapid systemic effect?
A. Oral
B. Intravenous
C. Subcutaneous
D. Transdermal
Correct Answer: B. Intravenous
Explanation: Intravenous administration delivers medication directly into the bloodstream,
allowing rapid onset. The speed of effect varies among medications and routes, but IV
administration generally produces the fastest systemic exposure.
Question 10. What is the primary purpose of therapeutic drug monitoring?
A. To determine whether the patient prefers the medication
B. To measure drug concentrations when appropriate and maintain therapeutic levels while
limiting toxicity
C. To eliminate the need for patient assessment
D. To determine whether the medication should always be administered orally
Correct Answer: B. To measure drug concentrations when appropriate and maintain
therapeutic levels while limiting toxicity
