Question 1 of 5
An older adult is seen in clinic. During the assessment process, all of the following are expressed or noted. Which is of most immediate concern to the nurse?
Correct Answer: B
Rationale: A productive cough suggests a respiratory infection, potentially serious in an older adult, requiring immediate evaluation. Forgetfulness, slow ambulation, or presbyopia are less urgent.
Question 2 of 5
A student nurse is caring for a client with iron deficiency anemia who is newly prescribed ferrous sulfate. Which action by the student nurse requires the supervising nurse to intervene?

Question 3 of 5
The nurse is preparing to administer the fourth dose of IV vancomycin to a client. Which set of laboratory values would alert the nurse to hold the vancomycin and notify the health care provider?
