Updated Visovsky & Zambroski Questions & Answers
SECTION 1: PHARMACOKINETICS & PHARMACODYNAMICS
Question 1
The nurse is teaching a patient about how medications work in the body. Which
statement correctly describes the mechanism of drug action at receptor sites?
A) Drugs must be metabolized before they can attach to receptor sites
B) Drugs work by attaching to receptor sites, either activating or blocking them
C) All drugs work by destroying receptor sites
D) Drugs only work on receptor sites located in the brain
Answer: B
Rationale: Drugs work by attaching to receptor sites on cell membranes. They can
act as agonists (activating the receptor) or antagonists (blocking the receptor).
This is the fundamental mechanism by which most medications produce their
effects in the body.
Question 2
A patient asks the nurse, "What does it mean when a drug is an agonist?" The
best response is:
A) "An agonist drug blocks the receptor site and prevents activation"
,B) "An agonist drug attaches to the receptor site and activates it"
C) "An agonist drug has no effect on receptor sites"
D) "An agonist drug destroys the receptor site"
Answer: B
Rationale: A drug agonist works by attaching to and activating receptor sites,
producing the same actions as the body's own natural chemicals (endogenous
substances). This activation leads to a cellular response.
Question 3
The nurse is administering naloxone (Narcan) to a patient who has experienced an
opioid overdose. What effect should the nurse expect from this drug?
A) Positive activation of opioid receptor sites
B) Partial activation of opioid receptor sites
C) No activation of opioid receptor sites
D) Destruction of opioid receptor sites
Answer: C
Rationale: Naloxone is a drug antagonist. When an antagonist attaches to a
receptor site, it does not activate or "unlock" it, resulting in no increase in cell
,activity. In the case of opioid overdose, naloxone blocks opioid receptors,
reversing the effects of the overdose.
Question 4
Pharmacokinetics refers to:
A) What the drug does to the body
B) What the body does to the drug
C) The study of drug classifications
D) The mechanism of drug action
Answer: B
Rationale: Pharmacokinetics describes the processes of absorption, distribution,
metabolism, and excretion (ADME) of drugs—essentially, what the body does to
the drug. Pharmacodynamics, in contrast, refers to what the drug does to the
body.
Question 5
The nurse is teaching a patient about oral medication administration. The patient
asks why water is recommended for swallowing tablets. The best response is:
A) "Water helps with proper metabolism of the drug"
, B) "Juice or milk can keep the drug from dissolving"
C) "Water helps to dissolve the drug and increase its solubility"
D) "Water keeps the drug potent"
Answer: C
Rationale: All drugs must be dissolved in body fluid before they can enter body
tissues. When the patient takes water with a tablet, it not only helps with
swallowing but also helps dissolve the drug and increase its solubility for
absorption.
Question 6
The nurse administers an intravenous (IV) antibiotic to a patient with severe
cellulitis. The patient asks why this medication is being given IV instead of by
mouth. The best response is:
A) "This antibiotic is not available in oral form"
B) "This antibiotic can act faster when given by IV than by mouth"
C) "This antibiotic can cause stomach ulcers if given by mouth"
D) "The prescriber ordered it this way"
Answer: B
