Question 1
A nurse is preparing to give an oral dose of drug X to treat a patient's high blood
pressure. After giving the drug, the nurse finds that it not only reduces the blood
pressure without serious harmful effects, but it also causes the patient to have
nausea and headache. Based on this information, which property of an ideal drug is
this drug lacking?
A. Effectiveness
B. Safety
C. Selectivity
D. Ease of administration
Correct Answer: C. Selectivity
Rationale: Selectivity refers to a drug's ability to elicit only the response for which
it is given, without causing other effects. An ideal drug would act only on specific
receptors to produce the desired therapeutic effect without causing side effects
such as nausea and headache .
Question 2
,The nurse is preparing to give a drug with certain properties. Which property of the
drug is the most compelling indication that it should not be given?
A. The drug is expensive.
B. The drug causes minor side effects.
C. The drug is not effective for its intended purpose.
D. The drug requires multiple daily doses.
Correct Answer: C. The drug is not effective for its intended purpose.
Rationale: Effectiveness is the most important property of a drug because it
determines whether the drug can achieve its therapeutic objective. If a drug is not
effective for its intended purpose, it should not be administered regardless of other
properties .
Question 3
What is the objective of drug therapy?
A. To provide maximum benefit with minimal harm
B. To provide minimum benefit with maximum harm
C. To provide total relief of symptoms regardless of harm
D. To provide as much benefit as possible
Correct Answer: A. To provide maximum benefit with minimal harm
,Rationale: All drugs have the potential to produce adverse effects. The goal of drug
therapy is to achieve maximum therapeutic benefit while minimizing harm. Drugs
are not ideal agents; healthcare providers must exercise skill and care to ensure
treatment results in more good than harm .
Question 4
When studying the impact a drug has on the body, the nurse is reviewing what?
A. Pharmacokinetics
B. Pharmacodynamics
C. Clinical pharmacology
D. Toxicology
Correct Answer: B. Pharmacodynamics
Rationale: Pharmacodynamics is the study of what the drug does to the body,
including the mechanisms of drug action and the relationship between drug
concentration and effect. Pharmacokinetics is what the body does to the drug.
Clinical pharmacology applies these principles to patient care .
Question 5
When studying the effects of drugs in humans, the nurse is learning about what?
A. Pharmacokinetics
B. Pharmacodynamics
, C. Clinical pharmacology
D. Toxicology
Correct Answer: C. Clinical pharmacology
Rationale: Clinical pharmacology is the branch of pharmacology that deals with
the effects of drugs in humans. It encompasses both pharmacokinetics and
pharmacodynamics as they apply to patient care .
Question 6
Why is it important for drugs to have ease of administration?
A. Fewer administration errors
B. Lower cost
C. Faster onset of action
D. Increased potency
Correct Answer: A. Fewer administration errors
Rationale: Ease of administration is an important property of an ideal drug because
it reduces the likelihood of administration errors. Drugs that are difficult to
administer are more prone to dosing mistakes and patient non-adherence .
Question 7
Which statement by a new nurse indicates that further study is indicated?
