Answer to Question 1
ANS: D
The nurse must exercise clinical judgment about the scheduling of new drug orders, missed dosages, modified drug orders or substitution of therapeutically equivalent medicines by the pharmacy, or changes in the patient's condition that require consultation with the physician, health care provider, or pharmacist. Adjusting the route is not within the role of the nurse. Documenting the response to PRN medications at the end of the shift is not an acceptable time frame. Educating the patient about the medication is within the nurse's role.
