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 Answer - C. Selectivity Correct
The drug is effective in lowering the blood pressure and safe in that it does not
cause harmful effects. However, as do most drugs, it causes other effects
besides the one response desired; therefore, it lacks selectivity. The oral form
provides ease of administration.
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. Answer - D. The drug is
not effective for its intended purpose. Correct
,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 a desired property for most drugs.
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 Answer - A. Fewer administration errors
Correct
Ease of administration increases convenience and adherence and can reduce
administration errors. Ease of administration is not related to side effects,
chemical stability, or reversibility.
The nurse teaches a patient not to consume alcohol with nitroglycerine,
because the blood pressure often drops significantly when nitroglycerine is
taken with alcohol. Which drug property does this illustrate?
A. Chemical instability
B. Drug interaction
C. Reversible action
D. Drug selectivity Answer - B. Drug interaction Correct
When two or more drugs are taken together, they can interact, causing either
increased or decreased drug responses. In this case, alcohol would increase the
nitroglycerine response. Chemical instability, reversible action, and drug
selectivity are not related to this situation.
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. Answer - C. The drug's pharmacodynamics Correct
Pharmacodynamics can be thought of as the impact of drugs on the body.
Pharmacokinetics describes the movement of drugs through the body.
Selectivity is the ability of a drug to elicit only the response for which it is given.
Predictability is the degree of certainty about how a patient will respond to a
certain drug.
When studying the effects of drugs in humans, the nurse is learning about
what?
A. Pharmacology
B. Clinical pharmacology
C. Therapeutics
D. Effectiveness Answer - B. Clinical pharmacology Correct
Clinical pharmacology is the study of the effects of drugs in humans.
Pharmacology can be defined as the study of drugs and their interactions with
living systems. Therapeutics, also known as pharmacotherapeutics, is the use
of drugs to diagnose, prevent, or treat disease or to prevent pregnancy. The
term effectiveness indicates that the drug elicits the intended response or
responses.
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.
Answer - Drugs are defined as illegal substances. Correct
A drug is any chemical that can affect living processes. All the other statements
are correct.
, What is the ultimate concern for the nurse when administering a drug?
A. Intensity of the response
B. Dosage
C. Route of administration
D. Timing of administration Answer - A. Intensity of the response Correct
The ultimate concern for the nurse when administering a drug is the intensity
of the response, which is determined by the dosage size, route of
administration, and timing of administration.
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 Answer - A. To provide maximum
benefit with minimal harm Correct
The objective of drug therapy is to provide maximum benefit with minimal
harm. All drugs have the potential to produce side effects. Because drugs are
not ideal, we must exercise skill and care if treatment is to result in more good
than harm
Characteristics unique to each patient can influence pharmacokinetic and
pharmacodynamic processes. What characteristics may determine the patient's
response to a drug? (Select all that apply.)
A. Age
B. Gender
C. Weight
D. Mood
E. Genetics Answer - A. Age
B. Gender
