Foundational Pharmacology Principles (Questions 1-9)
Q1. 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: The drug is effective in lowering blood pressure and safe in
that it does not cause serious harmful effects. However, it causes other
effects (nausea, headache) besides the one response desired; therefore,
it lacks selectivity. The oral form provides ease of administration, and it
is clearly effective for its intended purpose.
Q2. 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 produces an unwanted side effect.
B) The drug is difficult to administer.
C) The drug's effects are reversible.
D) The drug is not effective for its intended purpose.
Correct ,,,,answer,,,: D) The drug is not effective for its intended
purpose.
Rationale: If a drug is not effective, there is no justification for giving
it. Some drugs may be given even though they produce unwanted side
effects or are difficult to administer. Reversible action is actually a
desired property for most drugs.
Q3. Why is it important for drugs to have ease of administration?
A) Fewer administration errors
B) Less risk of side effects
C) Greater chemical stability
D) Greater likelihood of reversibility
Correct ,,,,answer,,,: A) Fewer administration errors
Rationale: Ease of administration directly correlates with fewer
medication errors by nursing staff and promotes better patient
adherence when self-administered. It does not inherently reduce side
effects, affect chemical stability, or influence reversibility.
Q4. When studying the impact a drug has on the body, the nurse is
reviewing what?
A) The drug's pharmacokinetics
B) The drug's selectivity
C) The drug's pharmacodynamics
D) The drug's predictability
,Correct ,,,,answer,,,: C) The drug's pharmacodynamics
Rationale: Pharmacodynamics can be thought of as the impact of
drugs on the body—what the drug does to the body. Pharmacokinetics
describes the movement of drugs through the body (what the body does
to the drug). Selectivity is the ability to elicit only the desired response.
Q5. When studying the effects of drugs in humans, the nurse is
learning about what?
A) Pharmacology
B) Clinical pharmacology
C) Therapeutics
D) Effectiveness
Correct ,,,,answer,,,: B) Clinical pharmacology
Rationale: Clinical pharmacology is specifically the study of the
effects of drugs in humans. Pharmacology is the broader study of drugs
and their interactions with living systems. Therapeutics
(pharmacotherapeutics) is the use of drugs to diagnose, prevent, or treat
disease.
Q6. Which statement by a new nurse indicates that further study is
indicated?
A) "Effectiveness is the most important property a drug can have."
B) "There is no such thing as a safe drug."
C) "Drugs are defined as illegal substances."
D) "There is no such thing as a selective drug; all medications cause side
effects."
Correct ,,,,answer,,,: C) "Drugs are defined as illegal substances."
, Rationale: A drug is any chemical that can affect living processes—
not just illegal substances. All the other statements are correct:
effectiveness is the most important property, no drug is completely safe
(all have risk), and truly selective drugs do not exist.
Q7. What is the overall objective of drug therapy?
A) To cure all diseases
B) To provide maximum benefit with minimal harm
C) To eliminate all side effects
D) To use the lowest possible dose
Correct ,,,,answer,,,: B) To provide maximum benefit with minimal
harm
Rationale: The goal of drug therapy is to provide maximum benefit
with minimal harm. All drugs have the potential to produce side
effects, and because drugs are not ideal, healthcare providers must
exercise skill and care to ensure treatment results in more good than
harm.
Q8. Characteristics unique to each patient can influence
pharmacokinetic and pharmacodynamic processes. Which
characteristics may determine the patient's response to a drug?
(Select all that apply.)
A) Age
B) Gender
C) Weight
D) Mood
E) Genetics
Correct ,,,,answer,,,: A, B, C, E (Age, Gender, Weight, Genetics)
