Answer to Question 1

Correct Answer: 4
Rationale: When the plateau of a drug has been reached, administering more of the drug will not produce additional benefit. Once the plateau of a drug has been reached, there is no time frame for an increase in dosage because an increase in dosage will not produce a greater effect. Telling the patient the nurse will check with the physician is inappropriate because the plateau of the drug has been reached; the physician will not change the dosage. An increase in dosage may cause interactions with other medications, but this is not the best answer.

Answer to Question 2

Correct Answer: 4
Rationale: Drugs with a narrow therapeutic index have a low safety margin and the concentration of the drug should be monitored by regular serum tests. The therapeutic index will give some information about safe doses, but this is not the most complete response. The therapeutic index will not help to determine if the physician prescribed the best drug for the patient. The therapeutic index will not help to identify interactions among the drugs the patients receive.
