Pharmacological Clinical Judgment, Safety, &
Terminology for 2023-24 answered
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 reduces the blood pressure
without serious harmful effects, but also causes the patient to have nausea and a
headache. Based on this information, which property of an ideal drug is this drug
lacking?
Effectiveness
Safety
Selectivity
Ease of administration - Correct answer C
-Rationale: The drug is effective in lowering the blood pressure and safe in that it
does not cause harmful effects. However, like most drugs it causes other effects
besides the one response desired so it lacks selectivity. The oral form provides ease
of administration.
The nurse is preparing to give a drug with the following 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 drugs effects are reversible
The drug is not effective for its intended purpose - Correct answer D
-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 a desired property for most drugs.
, Why is it important for drugs to have ease of administration?
A: Decreased medication errors
B: Less risk of side effects
C: Greater chemical stability
D: More likely to be reversible - Correct answer A
-Rationale: Ease of administration increases convenience and adherence and can
decrease administration errors. Ease of administration is not related to side effects,
chemical stability, or reversibility.
Blood pressure often drops significantly when nitroglycerin is taken with alcohol.
Which drug property does this illustrate?
A: Chemical instability
B: Drug interaction
C: Reversible action
D: Drug selectivity - Correct answer B
-Rationale: When two or more drugs are taken together they can interact, causing
either increased or decreased drug responses. In this instance, the alcohol
increased the nitroglycerin response. Chemical instability, reversible action, and
drug selectivity are not related to this situation.
Which term best describes the impact of drugs on the body?
A: Pharmacokinetics
