THROUGH 110 WITH QUESTIONS AND
EXPLANATORY NOTES
©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?
The drug produces an unwanted side effect.
The drug is difficult to administer.
The drug's effects are reversible.
The drug is not effective for its intended purpose.. Answer:The drug is
not effective for its intended purpose
f 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?
Fewer administration errors
Less risk of side effects
Greater chemical stability
Greater likelihood of reversibility. Answer:Fewer Admin errors
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?
Chemical instability
Drug interaction
Reversible action
Drug selectivity. Answer:Drug interaction
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?
The drug's pharmacokinetics
The drug's selectivity
The drug's pharmacodynamics
The drug's predictability. Answer:Pharmacodynamics
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?
Pharmacology
Clinical pharmacology
Therapeutics
Effectiveness. Answer:Clinical pharmacology
