The nurse promotes optimal drug effectiveness by doing what? (Select one that does not apply.)
- A. Incorporate basic history and physical assessment factors into the plan of care.
- B. Evaluate the effectiveness of drugs after they have been administered.
- C. Modify the drug regimen to modify adverse or intolerable effects.
- D. Minimize the number of medications administered to patients.
Correct Answer: D
Rationale: Incorporate basic history and physical assessment factors into any plan of care so that obvious problems can be identified and handled promptly. If a drug simply does not do what it is expected to do, further examine the factors that are known to influence drug effects. Frequently, the drug regimen can be modified to deal with that influence. Minimizing the number of medications administered is usually not an option because each drug is ordered for a reason of necessity for the patient.

- A. Teratogenic effects
- B. Toxic effects
- C. Adverse effects
- D. Therapeutic effects
Correct Answer: C
Rationale: Negative or unexpected effects are known as adverse or side effects. Teratogenic effects are adverse effects on the fetus and not a likely concern for an older adult. Toxic effects occur when medication is taken in larger than recommended dosages caused by an increase in serum drug levels. Therapeutic effects are the desired actions for which the medication is prescribed.
