An overwhelmed nursing student asks the instructor whether there are any tips that will make learning pharmacology easier. The instructor gives an example of the anticoagulant heparin. The instructor indicates that knowing heparin and comparing other drugs to it will facilitate learning the many anticoagulants. Which approach is the instructor using?
1. Mechanism of action approach
2. Generic name approach
3. Trade name approach
4. Prototype drug approach
4
Rationale 1: Mechanism of action is how the drug produces its physiological effect in the body. This approach does not limit the number of drugs that must be learned.
Rationale 2: Heparin is the generic name, but this does not help the student understand the drug.
Rationale 3: Trade names are specific to only one drug, so learning by this approach does not limit the number of drugs that must be examined.
Rationale 4: In the prototype approach, the student learns about one well-understood drug from a class of drugs. Learning about this drug helps the student understand the other drugs in the class.
