,, \Chapter 1: Orientation to
1. The nurse is teaching a patient how a medication works to treat an illness. To do this, the
nurse will rely on knowledge of:
a.
pharmacotherapeutics.
Pharmacotherapeutics is the study of the use of drugs to diagnose, treat, and prevent
conditions. Clinical pharmacology is concerned with all aspects of drug–human interactions.
Drug efficacy measures the extent to which a given drug causes an intended effect.
Pharmacokinetics is the study of the impact of the body on a drug.
2. What does it mean when a drug is described as easy to administer?
a.
It enhances patient adherence to the drug regimen.
A major benefit of drugs that are easy to administer is that patients taking them are more
likely to comply with the drug regimen. Drugs that are easy to give may have the other
attributes listed, but those properties are independent of ease of administration.
3. A patient tells the nurse that he was told by the prescriber that the analgesic he is taking is
very effective. Which statement by the patient demonstrates an understanding of the drug’s
effectiveness?
a.
“It might make me sleepy, and it lessens pain for several hours at a time.
A drug is effective if it produces the intended effects, even if it also produces side effects. Because no
drug is completely safe, the level of toxicity does not determine effectiveness. All drugs have side
effects and many react with other substances; these do not affect the drug’s effectiveness. Ease of
administration is independent of a drug’s effectiveness.
