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 reduces 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
2

,Rationale: Selectivity is the ability of a drug to elicit only the

response for which it is given. While this drug is effective (lowers

BP) and safe (no serious harmful effects), it causes additional

unwanted effects (nausea and headache), indicating a lack of

selectivity. Most drugs are non-selective to some degree. The

oral form provides ease of administration .

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 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

k k k k k k k k k k k




k administering it. A drug may still be given even if it produces
k k k k k k k k k k k




k unwanted side effects or is difficult to administer, as long as it
k k k k k k k k k k k




k provides therapeutic benefit. Reversible action is a desired
k k k k k k k




k property for most drugs, not a contraindication .

k k k k k k k k k




k administration?

A) Fewer administration errors

k k k k k k k




k adherence and can significantly reduce administration errors. Ease
k k k k k k k




of administration is not directly related to side effect profile,
k k k k k k k k k k




k chemical stability, or reversibility of drug action .
