A nurse is assessing a client who complains of a persistent, nonproductive dry cough after starting a new prescription for hypertension. Which of the following medications does the nurse suspect?
Correct Answer: A

The nurse is assessing therapeutic blood levels for a client receiving lithium (Lithobid). The nurse should recognize which of the following levels as toxic for this drug?

Question 3 of 5
Which of the following is the federal statute that regulates drugs and medications in Schedules I through V?
