The nurse learns that a drug needed by the patient is classified as an orphan drug and recognizes what as a reason for this classification? (Select one that does not apply.)
- A. The drug is rarely prescribed.
- B. The drug has dangerous adverse effects.
- C. The drug treats a rare disease.
- D. The patent on the medication is still effective.
Correct Answer: D
Rationale: Drugs are classified as orphan drugs when they are not financially viable for a drug company to produce either because of risk for lawsuits about adverse effects or because the drug is not prescribed, which is often seen in rare diagnoses. Generic drugs are not produced until the patent expires, but this has no impact on classifying a particular drug as an orphan drug. Generic drugs are often produced by companies that only manufacture drugs without conducting research, but this has no bearing on the classification of orphan drugs.
