1. Pharmacological Principles (1–15)
1. A nurse is checking a client’s identification band before
administering medication. Which right of medication administration
is the nurse verifying?
A. Right client
,B. Right dose
C. Right route
D. Right time
Correct Answer: A
Rationale: Checking the identification band verifies the right client. The
right dose, route, and time are verified by checking the medication order
and label.
2. A client refuses a prescribed medication. Which action should the
nurse take?
A. Administer the medication secretly in food
B. Document the refusal and notify the provider
C. Restrain the client and administer the medication
D. Ask the family to force the client
Correct Answer: B
Rationale: The nurse must respect the client’s right to refuse, document
the refusal, and notify the provider. Hiding medication, restraining, or
forcing is unethical and illegal.
3. A nurse is reviewing a medication order for a “loading dose.” The
nurse understands that a loading dose is:
A. A small maintenance dose
B. A larger initial dose to reach therapeutic levels quickly
C. A dose given only when symptoms occur
D. A dose that is gradually increased
Correct Answer: B
Rationale: A loading dose is a larger initial dose given to achieve
therapeutic drug levels rapidly. Maintenance doses follow to keep levels
steady.
4. Which term describes two drugs combined that produce a greater
effect than either drug alone?
A. Antagonism
B. Synergism
C. Tolerance
D. Dependence
,Correct Answer: B
Rationale: Synergism occurs when two drugs work together to produce
a greater effect. Antagonism is when one drug blocks another. Tolerance
is decreased response over time. Dependence is reliance on a drug.
5. A nurse is teaching a client about an adverse effect. Which
statement best describes an adverse effect?
A. The desired therapeutic effect
B. An unintended, harmful effect of a medication
C. A predictable side effect that is always harmless
D. A medication interaction
Correct Answer: B
Rationale: An adverse effect is an unintended and potentially harmful
effect. Side effects may be predictable but are not always harmless. Drug
interactions are separate.
6. Which condition would be a contraindication for a medication?
A. A condition that makes the drug dangerous to use
B. A condition that improves with the drug
C. A minor side effect
D. A therapeutic effect
Correct Answer: A
Rationale: A contraindication is a condition or factor that makes a drug
unsafe. It is not a side effect, therapeutic effect, or indication.
7. A nurse is reviewing a drug with a narrow therapeutic index.
What does this mean?
A. The drug is safe for all clients
B. The toxic dose is close to the therapeutic dose
C. The drug has no side effects
D. The drug can be given without monitoring
Correct Answer: B
Rationale: A narrow therapeutic index means the difference between
therapeutic and toxic doses is small, requiring close monitoring of drug
levels.
, 8. Which process describes the first-pass effect?
A. Metabolism of a drug by the liver before it reaches systemic
circulation
B. Excretion of a drug by the kidneys
C. Absorption of a drug through the skin
D. Distribution of a drug to tissues
Correct Answer: A
Rationale: The first-pass effect reduces the amount of active drug
reaching systemic circulation because the liver metabolizes it first. IV
drugs bypass this effect.
9. Which route bypasses the first-pass effect?
A. Oral
B. Rectal
C. Intravenous
D. Sublingual
Correct Answer: C
Rationale: Intravenous administration bypasses the liver initially, so the
full dose reaches systemic circulation. Oral, rectal, and sublingual have
some first-pass effect.
10. A nurse is teaching a pregnant client about teratogenic drugs.
Which statement is correct?
A. Teratogenic drugs are safe during pregnancy
B. Teratogenic drugs can cause fetal harm
C. Teratogenic drugs only affect the mother
D. Teratogenic drugs are used to treat pregnancy
Correct Answer: B
Rationale: Teratogenic drugs can cause birth defects or fetal harm. They
should be avoided during pregnancy unless benefits outweigh risks.
11. What is a black box warning?
A. A warning about a drug’s high cost
B. The most serious warning required by the FDA
C. A warning about minor side effects
D. A warning about drug storage
