1. A nurse is preparing to administer a medication to a patient. Which of the following represents the
generic name of a drug?
A) Tylenol
B) Acetaminophen
C) Nacetylpaminophenol
D) Extra Strength Tylenol
Answer: B) Acetaminophen
Explanation: The generic name is the official, nonproprietary name assigned to a drug (e.g.,
acetaminophen). Trade names (e.g., Tylenol) are brand names, and chemical names describe the
molecular structure.
2. Which phase of clinical drug testing involves a small number of healthy volunteers to determine drug
safety and dosage?
A) Phase I
B) Phase II
C) Phase III
D) Phase IV
Answer: A) Phase I
Explanation: Phase I clinical trials involve 20100 healthy volunteers to evaluate drug safety, determine
safe dosage ranges, and identify side effects.
,3. The nurse understands that pharmacokinetics involves which of the following processes?
A) The study of drug interactions
B) The study of drug absorption, distribution, metabolism, and excretion
C) The study of the drug's mechanism of action
D) The study of drug contraindications
Answer: B) The study of drug absorption, distribution, metabolism, and excretion
Explanation: Pharmacokinetics is defined as "what the body does to the drug" and encompasses
absorption, distribution, metabolism, and excretion (ADME).
4. A patient asks the nurse, "What is the difference between a side effect and an adverse effect?" Which
response is most accurate?
A) "Side effects are always harmful, while adverse effects are not."
B) "Side effects are expected, predictable reactions, while adverse effects are harmful and unintended."
C) "There is no difference; the terms mean the same thing."
D) "Side effects occur only with overthecounter medications."
Answer: B) "Side effects are expected, predictable reactions, while adverse effects are harmful and
unintended."
Explanation: Side effects are predictable, often mild reactions, while adverse effects are unintended,
harmful responses that may require intervention.
5. The nurse is reviewing a medication order. Which component is essential for a complete medication
order?
A) Patient's diagnosis
,B) Patient's age and weight
C) Drug name, dose, route, frequency, and prescriber signature
D) Patient's insurance information
Answer: C) Drug name, dose, route, frequency, and prescriber signature
Explanation: A complete medication order includes the patient's name, drug name, dose, route,
frequency, time of administration, and prescriber's signature.
6. A patient is prescribed a drug that has a high firstpass effect. The nurse understands that this drug:
A) Is extensively metabolized in the liver before reaching systemic circulation
B) Is rapidly excreted by the kidneys
C) Has a high bioavailability
D) Is administered intravenously to avoid this effect
Answer: A) Is extensively metabolized in the liver before reaching systemic circulation
Explanation: The firstpass effect refers to the metabolism of a drug in the liver before it reaches
systemic circulation, reducing its bioavailability.
7. Which of the following routes of medication administration has the fastest onset of action?
A) Oral
B) Subcutaneous
C) Intravenous
D) Intramuscular
Answer: C) Intravenous
, Explanation: Intravenous (IV) administration delivers the drug directly into the bloodstream, providing
the fastest onset of action.
8. A nurse is caring for an older adult patient. Which pharmacokinetic change is commonly seen in this
population?
A) Increased renal excretion
B) Decreased liver metabolism
C) Increased gastric motility
D) Decreased body fat
Answer: B) Decreased liver metabolism
Explanation: Older adults commonly experience decreased liver metabolism and reduced renal function,
affecting drug clearance and increasing the risk of toxicity.
9. The study of pharmacodynamics involves:
A) What the body does to the drug
B) What the drug does to the body
C) The study of drug interactions
D) The study of drug names
Answer: B) What the drug does to the body
Explanation: Pharmacodynamics is "what the drug does to the body," including the drug's mechanism of
action and the relationship between drug concentration and effect.
